Part 4 is the continuation of Part 3. Part 3 is mainly about how the restaurant operates given the current settings. Part 4 goes further to identify wastes and eliminate them, which is the notion of lean operations. To enrich your work, you would need to review and apply the concepts of lean operations in Module 06 and methods of process improvements in Module 04. In your report of this part, you need to present the following: (a) Explicitly state the wastes that you see in the earlier U-profile (Part 3). State if the process is balanced or not. Briefly discuss the effects of the wastes on production, revenue, and profit. (b) A brief proposal on how to eliminate the wastes that you find. (Hint: labor reconfiguration) (c) A new Extended Table to show how your proposal in (b) can work. Essentially, you would do some experiments (trials and errors) with the new Extended Table in Excel where: - The number of employees stays unchanged throughout your experiment. - Assume that you already cross-trained the workers and, hence, you can easily move them around the resources. - The number of workers at one resource can be understood as the percentages of time they work at that resource (for example: two workers work full time or 100% and the third worker spends only 35% of his/her time at that station). Thus, the number of workers can be presented as a decimal number (for example: 2.350 workers). - You can move the workers around the resources with increments as fine as 0.001 workers. - With a new labor setup, you should achieve all utilizations close to 100%, e.g. more than 99%. (d) Discussion on the new outcomes that you get in (c). Note that there is no single best new outcome! Your discussion emphasis should be on improvements in labor utilization, balance of the process, production, revenue, and profit. For future analysis, you can have different demand acceptance ratios for different products. However, you do not need to consider different DARs in this current project
