Assume that all other resources and equipment (e.g., cashiers, chicken, packing material, etc.) are always available and ready when needed. The sandwich making process is characterized as follows: Time (seconds) Resources (Workers) Used Cutting Chicken Gustavo Assemble Sandwich 5 Walter, Jesse Pack Sandwich Jesse a. What is the flow time of the process? (5 points) b. What is the capacity rate of this process (in minutes)? (5 points) c. If the factory hires Walter's twin (who is identical to Walter in all respects) to do the exact job as Walter (so that both twins are performing same task at the same time), by how much will the capacity of the process increase? Briefly explain the intuition behind your result. (5 points)
