Consider the following process in a cafeteria with 5 different food stations. The number on the right of each task is customers per hour, the number on the bottom is the time for each customer in sec.

a) Which activity is the bottleneck activity? b) What is the capacity of the whole process (customers per hour)? c) Redesign the process (combining tasks & use more than one staff to work on one task, etc.) so that the total capacity increases - without changing the number of staff.

Optimize the whole process. The sequence does not matter and each task can be combined with any other task. You can not hire more staff.

What is the current process capacity and what is the bottleneck?

Draw an improved process flow. What is the process capacity of the optimized process?
