Usability in Websites

Introduction

Based on our website frustrations encountered in everyday life and while doing assignments, we decided to do a research in finding a method that makes the life easier. On our research, we found this topic, Website Usability. And also, we find that much research is going on this topic. As a support to that, we decided to spread this message through our literature review. Based on Fisher’s (2011) research, 70 percent of e-commerce website users do not purchase through website because of the difficulty and confusing design of websites.

Literature Review

This literature review addresses the basic concept of website usability, how it is measured, what is usability testing of website, what are the tools using for website usability testing, benefits of website usability, what are the disadvantages of website usability testing, what is the cost of doing website usability testing, and impacts. Through this literature review paper, we need to create awareness on why usability in website is important.

Website Usability

Usability is the product quality that enhances its user’s ability to use the product without any difficulties or frustrations.  Usability in websites or website usability means the quality of the user interface design to perform the desired action of its user without any kind of confusions. According to Cappel (2007) website usability is measured on the learn ability, efficiency, and user satisfaction.  Web usability depends on various features of design including website’s presentation, its navigational easiness, its functionality and its usefulness to users (Huang 2007).

Measuring Website Usability

Measuring the usability of a website depends on various factors like errors or bloopers, inconsistent usage of web conventions, lack of proper navigation, etc. Cappel (2007) categorizes different measures of usability into three groups. The three groups are web design errors, web design conventions, and design features to promote usability (Cappel 2007). The following section deals with the measures according to their classification.

Web design errors

Under design error classification Cappel (2007) puts the measures of web usability that should be avoided. One of the attractive features of websites is the use of splash screen while loading, this feature affects the usability of the website because it takes a long time to load than the normal screen. The other design error is the usage of horizontal scrolling creates frustration in finding out the information from the screen, which also contributes the usability error. Then, the other important measure is the self link on home page, because in some cases the home page may contain some changing pictures that may lead the users a misconception of new page when they click the self link (Cappel & Huang 2007).
Another measure according to Market Ease Business Promotions (2008) that comes under design errors is hiding important information in Business to Business (B2B) websites behind registration barriers well before creating trust or creating an impression that is relevant to the customers will lead them to lose customers who are concerned about junk mail and unwanted telemarketers.

Web Design Conventions

Cappel and Huang (2007) grouped some of the web usability measures that should be followed into design conventions. Examples for the measures under the web design conventions are the following: Link appearance, home page link from Logo, consistency in giving reference, and formats like color, font, page layout, content, etc.  According to Nielsen and Loranger (2006), designers should not offer video streaming more than two minutes because it will bore the users.

Web Design Features

The web design features are those features that enhance the website usability. In this section, some of the features that enhance the website usability are discussed. One of such good design feature is Breadcrumb trail which shows the page where the user stands and also shows the path. This will help user to make sure them on right topic. The other good design feature, Site search capability, helps the user to go directly the topic the user need to read on.  The FAQ or help option feature helps the user to manage the confusing features or latest features that added to the website (Cappel & Huang 2007).
According American Disability Act, designers need to enhance the usability of the website for the people with disability. For example, Designers need to give audio support for those websites of legal and essential thing (USACM 2008). Some other design features are ‘Add to cart button for B2C websites’, ‘Add to compare button for B2C websites’, Instructions to complete the task and error prevention. The website should use the terminologies, according to audience of the website (Hinchliffe2008).
In e-commerce websites like ebay, the websites usability is not only based on the front end design, but also depends on the back end design. In this case the usability is measured by considering the following factors: Scalability, Availability/Reliability, Security, Usability, and performance (Ahmed). Scalability means whatever the number of users accessing website simultaneously should be serviced without fail. Usability is the ability to perform multiple task or single task by different users at same time. Performance is the fast response time. For example booking a train ticket or making a bid.

Usability Testing of Websites

In general usability testing is the testing approach in which the tester watches how the product users perform typical task to achieve their goal (Barnum 2008). Usability testing of websites means observing the web users behavior in doing task in websites. It varies according to users and the purpose of websites.
Two different types of testing approach are there, formative testing and summative testing (Barnum 2008). Formative testing is an iterative testing done during the development cycle of the website. Hence it is done during development; it helps the developers to change the usability errors easily and tested again. But, Summative testing is done after the completion of development of the product and before the release. The advantage of summative testing is the testing of the whole product, and its result will be used during the future development of the product. The disadvantage is, the summative testing is too late to incorporate the result into the product.
 The next important step is who and how many human resources needed to perform the usability test. Keeping an eye on strategy of business, the number of people involved in the usability testing process will vary (Barnum 2008). If the number is more, it will be a proof for the issues. According to Nielsen (2000), with the help of five users for testing, can able to find around 85% of the usability errors. More than five is a usability testing luxury. The other important criterion is the user selection. These five users should be selected from the expected audience or users of the particular website (Barnum 2008). For example, health care equipment selling websites, for this website the main users are those in the medical field, not the common people. According to Fisher (2011), reliability and validity in usability testing is achieved by participating users from variable background and characters. Based on this, we need to select the appropriate user.
Another stuff need to discuss is in usability testing is the requirement of a testing lab. But, according to Barnum (2008), there is no need to have a testing lab. But, based on research on web usability, in some cases the lab is required, for the advanced testing like eye tracking, and searching behavior need to done in lab.  Nielsen (2009) finds that the eye tracking heat map shows the users tendency to read the websites in ‘F’ pattern.
The one of the most important step is to create the scenario for testing. That means setting of the boarders, range, and target testing goal. For example, if we are testing the usability of textile store website, here we can fix a target testing goal like websites interactive design to define and view outfit (Fisher 2011).
 The next step is to decide the tools that we need to perform usability testing. This depends on the types and purpose of the websites. Then we need to proper note down the results.

Website Usability Testing Tools

Under this section, we are discussing some of the common tools that are used for usability testing of a website (Stalker 2008).
·         Methodologies- usability, web metrics, interaction design, usability, human-computer interaction, usability engineering, user-centered design and accessibility.
·         Planning, feasibility, and requirements- task analysis, icon intuitiveness testing and card sorting.
·         Design- cognitive Walkthroughs and prototyping.
·         Evaluation.
·         Competitive analysis and benchmarking.
·         Do-it-yourself usability tools and techniques.
·         Software- click capture, visitor timing software and eye tracking software.
·         Think out aloud (Barnum 2008).
·         Eye tracking. According to Tullis and Djamasbi (2007), usability also deals with keeping the information where the users easily recognize.  

Benefits

Nielsen (2001) elaborates the benefit of web usability from two dimensions: Users and Providers. According to users, the benefits are the following:
·         Satisfaction on the task they performed in the website
·         Comfortable in playing around the website
·         Easy achievements of their goals without frustration
·         Trust and confidence in using the website
According to provider’s point of view, the benefits are:
  •              Cheap development cost and lesser time consumption
  •              Lower support cost
  •        Minimized user errors
  •       Training time and cost is reduced
  •        Return on investment

Disadvantages

Web Usability has its own disadvantages are the following:
  •         It cannot satisfy all the users, especially in the case where users are from a broad range.
  •        Different ways of accessing websites
  •        It restricts the designers to attract the users by flashy design.

Costs

The cost of conduction usability testing of websites varies based on the factors included in the process (Barnum 2008). According to Barnum (2008), the cost will be a minimum of $5000 or may go up to $10,000. But for the business to customer websites, the cost will go up, because the usability testing is to be done both front end and back end of the websites. In this case it will go very high.
As mentioned earlier, if we are doing both approaches: formative testing and summative testing, the cost of usability testing will go high. The cost will also vary according to the audience of the website. The setting up of usability testing lab will also add up to the cost of usability testing.

Impacts

The following are the impacts of web usability:
  •        Productivity of users and providers increased
  •        B2C websites sales and revenues increased
  •        B2B websites created confidence and trust in customers
  •        Reduced the maintenance cost
  •        Increased the customer satisfaction
  •        American Government introduced an act called American Disability Act for websites
  •        Increased number of web usability testing
  •        Increased research on web usability

Conclusion

Through this literature review, we are providing some awareness on the topic website usability, how it is done, what are its benefits, disadvantages, cost and impact. Through this paper, we need to support the statement made by Scott (2009), which emphasize the need to make usability and design an integral part of the development process, at whatever rate it’s conducted

Motivation and Performance


Introduction
In this 21st century, the words ‘Motivation’ and ‘Performance’ have great value. As you know, both of these words will go hand-in-hand. Now, in almost all organizations, the reward system is based on performance which is called performance appraisal. At the same time, criticism comes in motivation package for the improvement of employee’s skills. In comparison to present world, in early times the rewards are just the offered wage and motivations are the corporate punishments. This literature review lights you with some of current motivation based performance approaches at some of the organizations or workplaces around the world.
Motivation and Performance
What is motivation? What is performance? From work and organization perception, motivation is the stimulus to achieve high performance. On the other hand, performance is outcome of proper motivation. As we all know, human beings are not machine, so they will have their own ups and downs in their performance. None can make humans a machine. But good managers can make them to behave like a machine. For that managers should know how to motivate their employees properly. The pioneers in motivation based performance are Mary Parker Follett (1918) and Elton Mayo (1933, 1945). According to their perception, resources can develop or collapse an enterprise. The human resource frame platform is based on the following assumptions. Organizations exist to serve human needs, and both organization and workers need each other because organisations need ideas, energy, and talent. On the other hand, people need careers, salaries, and opportunities. When the individual and organization fit is poor, one or both suffer. And if the fit is good, it benefits both. Wegmans also said that his organisation serves the needs of his organisations customer with keeping in mind that the organisation can achieve its goal only if it fulfil the needs of his employees.
In the view of Shields John, Performance does not mean just how ‘high’ or ‘low’, but it means different based on the perceptions that you are looking at with, like, how it is defined and measured? Who is and what purpose, it is defined and measured? According to production manager performance is labour productivity and for a customer it might be product quality or cost-attractiveness. But for an employee in the production line, performance is his ability to do good job based on the income security, and workplace health and safety. These varied definition of performance lights into two important aspects of performance. It is a remarkable process which is subjective, constructed, open-ended, and multidimensional. Performance is not only an individual phenomenon. It has group and organisation-wide dimensions, each with inputs, processes and results that parallel those operating at the individual level. In this sense, performance can be thought of as having sequential and scalar dimensions.

Difficulties in Motivation and Performance
According to Pritchard, People work for different reasons. Some people work for satisfaction; they feel good by doing good work and feel bad about the poor work. One of the job performance measure (Borman, 2004) concerns in manufacturing companies is focused on improving productivity of workers. Greguras (1996) describes that an employee can contribute in achieving the organization objectives through completing the assigned job in time. It is not possible to improve the performance of your employee based on the benefits attained only from the Organization. Improvement in performance has to achieve from your employees satisfaction. If an employee is satisfied, that employee will be happy and will be in higher energy level or excitement. This satisfaction motivates him to do more work in smarter way. In turn the individual performance and organizational performances increases. Managers have to motivate employees based on strong needs, basics needs, etc. None of us can able to get a clear picture of our own needs, then how will a manager gets the need of someone else.

One of the other barriers in motivating an employee is the changes in the objectives of Organization, arbitrary performance standards, the number of resources to get the huge work done, feedback mechanisms for the improvement of employees in criticism and disrespectful tone.  All these things will make the way to lose the good presence of mind for doing good work. These are also called disincentive factors in an organisation. People likes to control their work, people do not want to be held accountable for things they cannot control. People want feedback but not in the form of judgement. People want to valued, people do not want to waste their time. In a boarder view motivation is the process of changing one’s energy into one’s satisfied needs. It means making an employee to get completely focused to do the desired task of Organisation. For that, Managers should know his employees energy pool, which is the amount of physical, mental, and emotional resources a person has available to apply to different actions or tasks.
Another trouble comes in motivating your employees are the divergences. Each of your employees is different; they might be from different culture, economic levels, values, etc. Due to these divergences, you need to motivate your employees in their suitable way. For that you have to understand your employees desires, why they work in your organization, what are their goals, what are their hobbies, how they refresh when they are tired, etc. All these information guides you to motivate in your employees in a personalized manner. It is easy to say, but in practical, it is a hard task. Also, with greater diversity the challenge of motivation will also increase. In this scenario, the managers have to avoid demotivation due to frequent conflicts among groups of employees and within diverse groups. To motivate employees in diverse groups is a very elusive task.

One of the best ability to human is the ability to think. Because of this ability, you cannot use the same way of motivation for a long time. Humans need changes according to time. If you motivate your employee based on old motivational assumptions, your work will go in vein. The motivation is an ongoing and innovative process.
How to Overcome Difficulties in Motivation and Performance
One way of bracing employee is to provide effective motivation, which makes them more satisfied with what they are doing and committed to their jobs. They are motivated with money, but it is not the only motivator. There are other incentives which can also serve as motivators. As we all know, for achieving an effective work performance in an organization, work motivation is one of key factor as put by Luthans (1998). The new technologies, time management, leadership effectiveness will also to considered to understand how they relate to work performance. Although there are different features, all of these features are inter-related. For example, to motivate your employees, you should possess good leadership qualities which is a central feature of organisational performance. A good leader can direct their subordinate’s efforts towards the goals and objectives of the organization. There must be an appropriate form of behaviour to enhance performance. Based on the leaders ability to achieve effective performance from others, the leadership is defined. Akinboye (2005) defines leadership as managers motivating workers to work for certain aims that represent the values and the motivations, the wants and needs, the aspirations and expectations of both managers and workers.

With greater diversity, the probability of occurring human relation mistakes increases which result in low performance. In this situation, mistakes might happen due to different personalities, past experiences, partiality in leadership, etc. Because of these reasons, there is no one theory or model that can help all managers to motivate all employees for all time. Gordon (1996) notes, that the motivational needs became paramount when your workforce becomes more diverse and recognizing. The employee’s position and status in the organization, age, gender education marital status or any other socio economic characteristic has to be considered during motivation process. To overcome these issues, your managers should use a contingency approach to find the appropriate motivational theories to follow (Kreintner and kinicki, 1995). You can change behaviour of your employees by understanding the components of motivation, which are action, result, evaluations, outcomes and needs satisfaction, and how they work together.

For the effective performance management, the organisation has to validate the performance standards and measures which are directly relevant to what is required in the job position or role involved. Reliability, cost-effectiveness and felt-fairness are the other key requirements for effective performance. A Performance management system should meet the test of felt-fairness, both in terms of the decision-making process involved, or procedural fairness and the outcomes delivered, or distributive fairness.

Elgenhuis suggests a way to overcome performance difficulties by creating a winning organizational climate. In organization with a winning climate there is willingness to go and above and beyond the call of duty, to ‘go the extra mile’. This has a direct impact on the performance of the organization and also makes people to stay with organisation for long time.


Commonly Used Methods 
To improve performance, Honda provided better work environment based on survey which boosted results. In Europe, large number of organisations started taking feedbacks in the second half of 1990s.

Managers find a confusing array of regulations and procedures standing in their way when they seek to reward good performance. (Alan K. Campbell, 1978) In spite of pervasive difficulties encountered by all public managers, Campbell’s experiment with merit based compensation was good. All public hr managers started to fairly motivate and reward public employees for better performance is a recurring and consistent theme of public human resource management literature and practice. Another method is the effective reward system and an effective performance appraisal system (Badway, 2007) In this method, employee can accommodate his family and also allowed to have a say in decision making of the work they carried out.
The contemporary theories of motivation are rooted in the principle of hedonism (Kreitner and Kinicki, 1995), states that people seek pleasure and avoid pain. Moorhead and griffin (1995) suggest that the drive to satisfy some important needs is the common goal in various theories of motivation. According to Maslow’s, managers have to concentrate in physiological needs by paying reasonable wage and providing comfortable physical environment.
According to Falcone Paul, for progressive performance, Organisation has to develop people’s skills and valuing individual. While communicating the inabilities to an employee, organisation has to use polite way of communicating instead of harsh way. He suggests organisations to use sentences starting with “I expect...” This polite approach will construct your employees. You can help your employee to succeed in his job and in turn help in achieving your organisations goal, by taking a little care in your communication. Training or special direction to be provided, whenever possible, it’s best to address a problem with positive tools as opposed to negative methods. Training is a kind of punishment, a positive punishment. You should help the employee succeed on her job. Even if discipline must be administered in the form of a warning, it should still be delivered hand in hand with training and other affirmative employer efforts. Keep in mind as well that training is the glue that binds people to a company: Everyone likes learning new things and developing new skills. And training, more than anything, helps people reinvent their hobs in light of their company’s changing needs. Although motivation is internal and not external, noting drives an employee to renewed commitment more than being challenged and stimulated by a new learning curve.

Conclusion
According to Kroth(2007), even though scholars proposed integrated motivational theories, there is no generally accepted models for all employee motivation. In this review, you can find many theories, but none of the theories can be used for a long time. To achieve a good performance, you should motivate your employees in an appropriate way. To find an appropriate way, managers should continuously follow your employees and has to find out what are their current needs and desire. These difficulties necessitate the need for human resource management team in an Organization.

International Business Strategies

Introduction
In this article, you can see some of the strategies used in doing business. This article will glance through some of the business strategies.
Multi-Domestic Strategy
Multi-Domestic strategy is an international strategy, which will be effective while entering into a new nation having many differences from the firm’s nation of origin. Implementing this strategy helps in localizing the firm to the people of the new nation. In this strategy, the firm concerns more for local responsiveness than the global product, which means that their product will be customized to the local demands and also the firm is controlled by local managers. This decentralized control reduces the political risks in managing the firm in the new market. This Strategy has less impact on international human resource management.
Global Strategy
Global strategy is good to enter into the new nations which have similar culture to the firm’s nation. In this strategy the control is centralized, which means that firm is less localized. The product of the firm will be same all across the nation. The activities across the nation will be well coordinated and cost effective and faster product development.
Transnational Strategy
Transnational strategy is a combination of multi-domestic and global strategies. This strategy integrates the global competitiveness with local responsiveness. It is not easy to implement. It has huge human resource impact.

Inventory Management

Introduction
Inventory management is the process of managing or controlling stock of resources of economic value by minimizing the cost of resource storage and maintenance in order to meet the customer requirement in right quantity, right place, right time and right cost, where the resources are manpower, machines, capital goods or material at various stages of production. This paper describes the needs and methods of inventory management. It also provides some good ideas on the risk and benefits of keeping inventory.

Inventory Management

One of the important parts of supply chain management is the inventory management. It is the process of maintaining appropriate level of inventories in the warehouse. The basic processes in inventory management are analyzing the inventory requirement, setting inventory targets of the firm, implementing replenishment techniques in maintaining the inventory, monitoring the usages of goods, accommodating the inventory balances, reporting inventory status.
According to Sookdeo, inventories are of different types like inventories raw materials and purchased part, partially completed goods, finished goods. The functions of inventory are to meet the expected demand, to smooth the production requirements, to increase the speed of production, to prevent stock outs, to take advantage of order cycle, to help hedge against price increases, to permit operations, to get advantage of quantity discounts.

Need for Inventory Management

The reason why companies keep inventory is to meet the demands of their customers, to keep the organization running, to get lead time, to avoid financial risk, to get discounts in price, to meet the sudden requirements, etc. The Companies want profit, for that their business has to run good. In other way, they should be capable of meeting the customer demands. Improper inventory management can cause loss to a company.
The product manufacturing companies get profit by selling their products. But to manufacture the product, resources should be available in inventory when it is needed. To attain profit, the inventory should be reliable, efficient and affordable. Improper management of inventory may lead to either excess stock or insufficient stock. For the successful management of stock, the stocks should be classified properly. The inventories are of different types, some goods may get damaged, if it is stored for a long duration. On other hand some goods are needed more and some are less in amount while manufacturing a product, in that case the stocks should be maintained in proportion of usage. That means, the goods used more should be stocked more and the goods used less should be stocked less. This proportional way of keeping inventory improves storage space utilization and efficiency.
Safety stock is the additional stock above the current and short term needs. The necessity of safety stock comes into existence when the unexpected element of event happens. For example, once due to some technical or natural reason, the replacement order for the inventory delayed, that its lead time increased a lot. At that time, the firm has to depend on the safety stock to run their business.
Anticipation Stock is the stock of goods stored in the view of performing a marketing promotion or an upcoming season or any event. The firm has to decide first on the promotional activity and has to start stocking the inventory for that event.
Hedge stock is the stock kept or accumulated based on the expectation of rising prices or supply uncertainty in the market place.

Implementing Inventory Management

One of the important steps to maintain a good inventory is the purchasing plan. Purchasing plan is important, because it helps to prevent the shortage of stocks. The company should find out the usage of stock, based on other conditions like different seasons, festivals, etc. In this plan, company should know when to order for supplies, when to keep high stock, what proportion of goods to be stocked, how long a good can be stocked, etc.
Another method for inventory planning is accurate demand forecasting. In this method, software systems predict the future demand of the product by using mathematical formulae based on historical usage data. This demand forecasting is an ongoing process; it can be done based on the duration of acquirement of inventory goods.
Inventory monitoring is the other important process in maintaining accurate inventory management. In this process, Firm has to track the arrival of product, usage of product, shipment of product, and disposition of inventory items to ensure the accuracy of inventory management. A cycle counting process can be done for this purpose.
Inventory report is the overview of what is there and what is not there in the inventory. Based on these reports, the Firm has to make decision for managing the inventory.

Effective inventory management
An effective inventory management is needed to meet demand of the customer while keeping inventory costs in a reasonable level (William 2005). The following are some of the methods to implement effective inventory management.
The firm has to implement a system to track of inventory details. To manage an inventory, the firm should know the count of resources in the inventory. For counting the inventory, the firm can use either an inventory counting system which counts the number of items in the inventory at periodic intervals or perpetual inventory system which keeps track of removal of items in the inventory continuously. This helps in monitoring the current availability of each item in the stock. Based on this count, the firm can replace orders of needed resources.
Another way to manage the inventory effectively is by doing a reliable forecast of demand. For attaining this forecast, the firm can use one of the following inventory methods. Two bin system and Universal –barcode method. In two bin system, the inventory is divided into two containers. According to this system, the firm should reorder for goods when the first container is empty. On the other hand, universal barcode that is printed on a label which has information of the item to which it is attached.
To meet the demand of customer, the firm should have a good knowledge of lead time to replace a resource. Lead time is the time interval between the ordering and receiving the item. In this case, firm has to replace an order considering the lead time. In other words, the firm has to replace an order with lead time.
For managing the inventory, firm should be able to estimate reasonably the following costs. Holding cost is the cost to store an item in the inventory for a period of time. Most of the
cases, the holding cost is calculated in a year. Ordering cost is the cost of ordering and receiving an item. Shortage cost is the cost of an item when the demand exceeds supply.
Another method to improve inventory management is to classify the system based on ABC classification system. In this classification, some goods have given high importance and classifying inventory according to some measure of importance and allocating control efforts accordingly.
Replenishment order in inventory management is done based of the following models. The following model provides the accurate details of the time at which replenishment has to be done.

Economic order quantity model
In economic order quantity, the quantity of inventory is based on the following assumptions and formula. The assumptions are only one product should be involved, annual demand requirements should be known, demand should be there throughout the year, lead time should not vary, each order should be received in a single delivery, and there should not be any quantity discounts.
EOQ= square root of {(2*annual demand*order or set up cost)/annual holding cost}

Economic production model
Economic production model is based on the following assumptions lime production should be done in batches or lots, capacity to produce a part exceeds the part’s usage or demand rate, assumptions of EPQ are similar to EOQ, orders are received incrementally, only one product should be involved, annual demand requirements should be known, demand should be there
throughout the year, lead time should not vary, each order should be received in a single delivery, and there should not be any quantity discounts.

EPQ= square root of {(2*annual demand*order or set up cost)/annual holding cost}

Latest Trends in Market

Now in markets, there are different methods and tools are available to manage inventories like enterprise resource planning, manufacturing resource planning, just-in-time and lean manufacture. The application of information technology in grocery industry has reduced the cost and time to process an order and in turn improved the supply chain performance (Casher and Fisher 1997).
Enterprise Resource Planning (ERP) is the latest tool used in inventory management. An ERP is a real time information system which is modularized and integrated with a wide range of functional scope responsible for the processing and management of business transactions (Paull 2010). This ERP system integrates information across all departments. It helps in the flow of information among different processes and functions. It tracks manufacturing process, order entry, inventory details, etc at the same time. Hence, this is a real time system, firms can take decision on inventory based on this tools report. With the help of this system, Firm can able to see its inventory details at any point of time.
For example in trade industry, the daily operations involve procurement management, shipment schedule, consolidating sales orders, and delivery. With the help of a proper inventory management system or ERP system, the industry can automate its process.
According to Synergy-focus case study on trading industry in China, the implementation of inventory control system, the industry’s improvement in efficiency is 300%.
Manufacturing resource planning (MRP) is the planning process in which all processes in the manufacturing industries are integrated like business planning, production planning, order processing, capacity requirement planning, forecasting, inventory control planning, etc. According to Giraffe production system, the benefits of manufacturing resource planning are the following:
Order entry and production forecasting which deals elimination of duplicate information, attaining consistent productivity data across the enterprise, and making commitments based on capacity. Resource planning handles the forecast and plan of both human and machine resources. It also helps in attaining improved productivity and reduced production costs. Production Scheduling provides priority assigned to each order. It tracks jobs and generates reports automatically. It also does the rescheduling of uncompleted jobs. Order fulfillment is the other benefit of MRP. It improves customer service and product delivery on time.
Just-in-time production system purpose is to produce and deliver finished goods just in time to be sold. According to Schonberger, the purpose of JIT is to “produce and deliver finished goods just in time to be sold, sub-assemblies just in time to be assembled into finished goods, fabricated parts just in time to go into subassemblies, and purchased materials just in time to be transformed into fabricated parts." In Just-in-time system, the firm works with minimum finished goods in the inventory.

McDonalds Inventory Management systems
McDonald uses Just-in-time inventory management system (Aktinson, 2005). As the name suggests, Just in time provides the supplies for the customer in time. When a customer orders a burger, McDonalds does not start to cook. It reheats and assembles the burger according to the particular order. If McDonalds begins to cook food when a customer places an order, McDonalds’s will take time to prepare a burger. As McDonalds is a fast food, it cannot make a customer to wait for a long time to get the ordered burger. With the help of just in time inventory management system, McDonalds pre-cook a batch of hamburgers and keep them under heat lamps. They keep them as long as possible and eventually discard what could not be sold. The advantage of this system is to serve a customer as fast as possible while having the finished product sitting in the inventory as short as possible.
The other benefit of just in time inventory management system is that the product will be good in quality. Because of this system, McDonalds prepares hamburger ‘just in time’. McDonald’s ability to produce faster reduced the ordering cost of the customer. Because of their ability to prepare fast, the customers need not to wait long for burgers. This firm has lower inventory levels, which may cause a bigger problem during high demand. But, McDonald’s ability to make burgers in record time prevents them from those situations. The holding cost of burger parts are costlier, hence it will be spoiled if it is kept for a month of time. If this frozen burger parts are cooked, the spoil time increases to 15 minutes. Because of this, in McDonalds old system the cost of burger was high to absorb cost of spoiled burger. But now they can prepare burger in record time, as a result of that there is less spoiling of burger in turn low cost of burger. Hence, this Just in time system is beneficial to McDonalds.
The advantages for McDonalds for using just in time inventory management system are reduction of cost of ordering and cost of holding, and reduction in safety stock. The reason for keeping the safety stock is to meet inconsistency in lead time and demand. In McDonalds case, the supplier is internal and they are using just in time system, so they can reduce the lead time and variation in lead time (Aktinson, 2005).

Conclusion
In short, this paper covers all the aspects of inventory management benefits, risk, etc. In this report, you can get information about the benefits of inventory management. This paper is also mentioning about the different methods followed in inventory management. This also details one of the inventory management based on the case study of McDonalds. From this paper, you can understand the reason, why inventory management is important in business process.

Project Life-cycle Management

Product Lifecycle Management (PLM) is growing rapidly with product complexity and offering greater competitive edge in business process. The purpose of this paper is to provide awareness of product lifecycle management in general and in our organization. On the other hand, you can understand avail that our organization achieving from PLM. This paper provides insights into SAPs PLM solution, by referring to some companies which are using PLM solution. Also, this paper discusses the issues associated with implementing PLM solution.
Product Lifecycle Management
Product Lifecycle Management (PLM) is the process of monitoring and controlling various stages of production cycle, starting from order of product, pricing of product, buying of raw materials, training of resources, designing of product, processing of raw materials, testing of product, packing of product, and delivery of product, in a systematic way.
PLM is an essential tool for managing needs of global competition by fulfilling the reducing product and component lifecycles, and growing customer needs.  By using PLM, an organization attains the ability of controlling their product cycle. It integrates the supply network and manufacturing of product. Doing this, an organization can bring new products to the market in less time, effort, and expenditure, with an added advantage to customer like reduced cost of product but the same good quality and quantity.
The product lifecycle management manages the lifecycle by keeping track of the following details in the system:
  • Terms and abbreviations used in this field like lifecycle, phases of lifecycle, definition of product, jargons used in the lifecycle and process, and so on.
  • Working domain/field of document (Document is the product of our organization) like telecommunication, banking, production, literature, travel, etc.
  • Product information models and product models like what type of document is to be delivered and version number of the document is to be used for making new document.
  • Product (document) lifecycle management and principles available in the organization like status of the product, version of the product, resource/author of the product/document, etc
  • Processes involved in product lifecycle. For example, in documentation review process, there are other process like peer review, team leader review, technical review, quality review, and customer review.
  • Instructions which helps to apply the concept in routine business.

Like most of manufacturing's latest era transitions, the product lifecycle management revolution is driven by the auto industry based on industries evolving need to become more collaborative, adaptive, flexible and responsive. And PLM is just the beginning of a revolution that turns information into a more usable and accessible tool. According to experts, automotive and aerospace industries are the PLM leader for the rest of manufacturing industries.
Product Lifecycle
In our organization, which is mainly into technical communications, the product lifecycle that we follow is Document Development Lifecycle (DDLC). DDLC is same as Software Development Life Cycle (SDLC). In DDLC, the various levels of processes involved are analysis and collection of resources available, design of document, development of document, review of document, and release of document.
Benefits of PLM
Like any other organizations, our organization also benefits from PLM. The following are the benefits of PLM:
  • It eases and standardizes the processes involved in our DDLC. The standardization of process helps in switching resources for an assigned work. It clearly shows the current status of product development. Hence, a new resource can easily start the job.
  • It reduces the time consumed for the documentation process by avoiding the searching time to locate resources and reusing the previously documented documents. Under PLM process, all the resources like templates, style guides, definition, etc. will be stored in this system. This storing of old data and design reduces document creation time.
  • It reduces the cost of documentation process by reusing, previously documented documents and design. By reusing the previous version of the document, the author should only need to add the new feature to the present document. Almost all the software products are undergoing changes. Every other release, a new feature will be added. In such case, the reuse of older version of document with needed modification saves a lot of money and time.
  • It saves the disk storage space by eliminating redundant documents and designs. PLM system will track the contents of disk and only allows a copy of document to be saved in the system.
  • It helps people throughout an organization to work together more effectively. For example, when one resource is writing a document, other resource can design a template.

Difficulties of PLM
Implementation of PLM takes a long time. To implement PLM successfully, an organization needs expert in their field of work. A well built information technology team is needed to maintain and operate PLM systems. It changes the whole process of an organization. It computerizes all the operations in an organization. The other important issue is the change in lifecycle of a product. This change creates the need for the regular updating of information to the system, thus making it a continuous process.
SAPs PLM Solution
SAP PLM supports the following areas in core business processes:
  • Product Management, which helps in planning and decision making for achieving the objective of big corporate growth. It also helps to create product strategy and planning, innovative management, and requirement management.
  • Product Development and Collaboration, which deals with sharing critical information such as project plans, previous documents, resources available, product structure, service bulletins, audit results, share work across teams, etc. It also deals with product quality management and product change management.
  • Product Data Management, which tracks data used in project, maintenance and modification of data, storage of data, proactive service to retrieve data and publishing of processed data.
  • Lifecycle Management, which helps in pricing and standardizing of product. It also helps in the integration of project requirement, tool, and resources.

Benefits and Issues of Companies with PLM
Kongsberg Automotive, which is an automotive company that looks into commercial vehicle market, uses SAP PLM for attaining internal collaboration in R&D. Using PLM, the company increased their efficiency by reducing the total cost of R&D, reducing time for R&D process. It also provides a secure platform for collaboration with other external companies.
Aker Solutions uses SAP PLM to manage its worldwide engineering data by storing 3D models and drawings in a unique global database. When implementing SAP PLM, the problem faced is the viewing formats of huge set of legacy drawings and models stored on various file servers and local product data management system. Here, the concern is to convert all these files and import them to SAP. Because of this issue, the migration process of files has to be done in two steps, one step to convert and next is to import. With the help of Cideon’s Import PDM program, Asker solutions has migrated the files step by step based on the need.
Canadian National Railway Company uses SAP PLM to overcome their key challenges like improving focus on customer and profit, creativity and innovation, merging organizational structure and systems of four railways, manage workforce diversity, productivity, efficiency and reporting.    
Conclusion
Throughout this report, you can see the information regarding product lifecycle management, mainly using SAP PLM. Even though, implementing PLM system has some difficulties, it has got a high value in the competitive business process. In short, PLM provides better control over the lifecycle of product which in turn helps in rapid growth of business.

International Strategy and International Human Resource Management

As a result of globalization and technology advancement, most of the companies and their work force are influenced by global pressure and competition. Because of these global influences, firms introduced the need for the proper international strategy and International Human Resource management. International strategies are those methods or approaches taken by a firm to extend their business across borders of their home country (Gillonn 2004).
According to Schuler (2009), the result of internationalization of business resulted in the increase of travel across the border, fast and easy communication across different cultures, fast development and transfer of technologies, improvement in education, free trade between the countries, pressure on cost and migration of people from one country to other countries. Because of this, People and their organization exposed to high pressure and competition.  In this scenario, the scope for international human resource management (IHRM) or globalized human resource management comes into existence.
According to Brannen (1999), good strategy and good strategic implementation are the good signs of good management. Based on good management signs and the strategy of go international, IHRM has developed (Lisbeth 2009). IHRM deals with the handling and researching of the issues faced during the management of human resources in enterprises in the global environment like the development of global mind-set in human resource functions by aligning HR processes and procedures for the enhancement of global strategies and competitions.
The some of the key aspects of IHRM are the cultural differences between the firms and the employees of the firms, the compensation methods in different countries, political situation of the countries, etc. IHRM has to deal with the issues of expatriates and foreign locals of the host countries. International human resource management is different from domestic human resource management (Vance 2006).

Aspects of International Strategies and Its Relationship between IHRM

Firms use different strategies for the expansion of their business to different countries. The following are some of the international strategies and their aspects based on the international human resource management.

In Licensing and Subcontracting strategy, a firm makes an agreement with foreign countries firm to manufacture or assemble its products and to export it back to the original firm’s country (Schuler 2009). Here the internationalization happens through export of one product from subcontracted firm to the original firm. In this method, A Firm gives license to other firm to franchise its brand and products.  In this strategy, the international HR issues effect in a small way. For the successful implementation of this strategy, the firm needs to guarantee the human rights of production workers and to make sure through training of franchisee to stick to the standards created by the franchisor.
Outsourcing is another kind of strategy for extending business to other countries from a firm’s home country. In this strategy, a firm gives contract to other firm in different country or same country to do their supporting works, so that the original firm’s resource can focus on their core competencies. For example, call centers, accounting, etc.  For the success of outsourcing, the international human resource management has to do proper communication with the people from same and different countries, able to assign suitable employees, fix proper compensation and benefits, give good training and development, good employee relationship, etc.
Offshoring , in this strategy a firm relocates one or more aspects of its business process to a different country for its strategic or competitive advantages like low cost and improved quality products. Here the role of international human resource management is to deal with the anxiety of the employees of home country, regarding job security. The other responsibilities of IHRM are relocating services, infrastructure for starting the business, communication skills in both languages, managing political stability, finding suitable skill sets, enforceability of intellectual property rights, etc.
Wholly Owned subsidiary strategy is an approach in which a firm acquires another firm from the country to which the original firm wants to do business. Mergers and Acquisitions come under this strategy. In this case, the firm acquires the whole firm or the infrastructure of the other firm. In this scenario, the success is based on the ability of IHRM to integrate both firms’ culture and HR policies. 
International Joint Venture Strategy, is the one in which two or more firms from different countries start a new business in one of the partners country with shared ownership and responsibility. But this new business is entirely independent on their parent companies, except their joint control. International Joint Venture is an equity sharing arrangement between two companies (one local, one foreign) that pool their resources, share risks and operational control to operate an independent business unit on a continuous basis to attain strategic objectives (Geringer & Hebert, 1991). In this new business the challenges for the IHRM are the creation of work force, culture, and practices. The one of the important key for the success of international joint venture is the agreement and the clarification on the agreement between the partners. In case there is lack of clarity in expectation for performance of resulting organization, which may eventually cause the early dissolution of the venture.

Conclusion

The above research and analysis on the importance and role of international human resource management on international strategies show that a global business can be a failure, if the international human resource management is not done properly. For the successful implementation of international strategy, human resources should be managed properly.
