A media and communications firm made the following value stream map in order to clarify the production system. The table below the VSM shows the resource and performance data for the four steps in the system. The WIP data in the table indicate the amounts of work-in-process held before the second, third, and fourth How much time per unit is needed for processing and changeover at the Ink Lab step? (Exclude the effect of uptime in your calculation.) The time needed for processing and changeover is seconds per unit. (Round your answer to two decimal places.) Considering now the uptime of Ink Lab, what is the capacity of this step? The capacity of Ink Lab is units per hour. (Round your answer to two decimal places.) The bottleneck in the production process is Pressroom which has capacity 4.87 units per hour. If demand and throughput for the system are equal to bottleneck capacity, what is the sum of WIP times for the system? (See above for explanation of WIP.) The sum of WIP times for the system is hours per unit. (Round your answer two two decimal places.)
