? and Section # of This paper aim to answer questions regarding two case studies, it would elaborate over the concepts of Material resource planning and Just in time techniques and show their implication in real life scenarios. MATERIAL REQUIREMENTS PLANNING Why did peter have such problems getting to the relevant information? There are a number of different activities that take place in order to complete one unit of production. As in the case of Psycho sports, one table tennis bat was made up of nine different parts put together through two assemblies. Psycho sports did not have any automated system to record the number of purchases being made and when they are used and how much stock is maintained in the inventory. As sales were increases and the buyers now included large retail stores, it was becoming increasingly important for psycho sports to keep track of the production in order to meet the demands in a timely fashion. Peter found it difficult to get all the information as the structure was entirely disintegrated and manual. There was no system that recorded the information and there was no single worker that managed the entire inventory levels and kept the information in an integrated form. There was no central database or system that held and updated all the information regarding the inventory levels of different parts. The data was all decentralized and with different workers responsible for different parts who were more often than not, unaware of the inventory levels. Furthermore, the purchasing was also manual, hence, there was no record of the number of item that were purchased and used. Exercise 1 (a) Draw a single level bill of material for each level of assembly; Face assembly Item no. Quantity 6511 Rubber Face 2 2547 Wooden Inner 1 8561 Foam Panel 2 Handle Assembly Item no. Quantity 1821 Handle 1 9110 Nail 2 (b) Complete indented bills of material Item no.

of the different parts and assemblies are different; hence, it is difficult to determine when to order which part. This also leads to backlogs and access inventory. When the sales are completed, there is often a lot of inventory that is left and this creates wastage. Moreover, it is difficult to keep track of the economic quantity of ordering and this adds to the complications to the ordering process. (c) To resolve this problem an automated system could be implemented that would keep track of all the inventory in a single database and order inventory when it reaches the minimum point in order to avoid backlogs as well as excess inventory. Furthermore, the quantities of ordering could be standardized to simply the system. (Monk & Wagner, 2007) JUST IN TIME To what extent could (or should) dean expect to apply the philosophies and techniques of JIT to the running of the staircase cell? Although the business process of the staircase cell involves customization according to the needs of the customers, the main functions are the same. These main processes make up the major chunk of the work. With the implementation of JIT techniques the process could be separated and workers would work over their allotted function. For example, some workers can be given the job to cut timber, some would be responsible for sanding, some workers would be running the machinery and so on. This way the process would flow through a series of steps. Customization could be done through specifying the details of the design and other specifications to each process areas. JIT centers upon continuous improvement and this philosophy is implemented through maintaining quality, flow and employee involvement in the work tasks from the start and till the end of the production process. (Betley et al. 2005) Making the work area free from clutter and forming an organized flow of work processes would make production simpler and quicker as orders would be completed in a timely manner. Having one person to take charge of the doors proved to be a success as it aided specialization. The job was done more efficiently when the workers focusing over a certain specialty rather than doing a number of different things together. Having applied the JIT technique there would be more efficiency in terms of meeting the estimates and deadlines in time. What are likely to be the main categories of costs and benefits in establishing the cell? Are there any non-financial benefits that could be taken into account? Establishing a separate cell would mean that there is a separate dedicated area to manufacture staircases. There is obvious upfront financial cost in setting up the separate production cell for the staircase. Moreover, there may be considerable reluctance from the workforce to work in a confined area as employees are usually reluctant to change. Most of the joiners were capable of making any product and they enjoyed the wide variety of challenging work. With JIT techniques in place, workers would be specializing in certain areas and although they could be rotated around, the work would involve learning a specific skill and mastering it, this could be a set back to the workers who like to be a part of the production from start to finish. Establishing the cell could also hamper customization and B&B may have to eventually move towards standard staircase designs with less customization. Furthermore, they would have to increase the production in order to fully utilize the cell. However, on the contrary, the cell would be a dedicated area where the functions would take place. It would be more organization and hence, save space while providing the employees with a better and cleaner environment to work in which is less congested. the cell would reduce the exertion of the workers, who currently have to walk a lot to get to one place to another and carry items of the way. Establishing the cell would get the job done faster and more efficiently. There would be greater throughput with the help of a step by step process and orders could be completed more rapidly. (Steavenson, 2008) At what stage, and how should dean sell his idea to the joinery manager and the workers? The idea of implementing JIT techniques to the joinery department is something that could make the department more competitive and help solve the problem that it is currently facing. Once Dean has established and analyzed the costs and benefits associated with the implementation of the idea, it would be the right time to communicate it with the joinery manager to get more insight to the situation and how it could be improved. Dean could show the joinery manager the loss that the department is incurring due to a disorganized process and how JIT could eliminate this wastage and help minimize costs whilst increasing efficiency and quality. With the establishment of a separate staircase cell there would be less clutter and congestion in the work area. Workers having skills over most of the work processes can be moved around and to do different jobs and the overall productivity would increase as workers would be faster and with a properly formulated work process, the production would be quicker, thereby eliminating the problems regarding the failure to meet estimation and deliver times. These factors, if properly communicated with the joinery manager, would sell the idea as there is no denial to the advantages of implementing the JIT techniques to this business area. The workers may have to be convinced through highlighting the benefits to them and their work practices. They would not have to move around as much and would be allowed to rotate their jobs from time to time to enrich their work experience. What risks are associated with deans proposal? With the new system in place the production capacity would be increased so there would be more production expected than before. The joinery department of B&B was known to make products based on the exact requirements and design of the customer. Through the introduction of JIT techniques, the customization may be affected to some extent and could influence the sales of the company. Moreover, Setting up an entirely new system requires the implementation of change management through that department. Mostly, workers are reluctant to change and need to be guided and trained in order for them to accept the new process and cooperate with it. BIBLIOGRAPHY Betley, A. Mayle, D. & Tantoush, T.
