Question 4 2 pts (Chapter 8) Consider a process with three process steps, each of which is staffed with one or more workers. The sequence of the three steps does not matter for the completion of the product. Currently, the three steps are operated in the following sequence: Do step 1 then step 2 then step 3. Assume there is a buffer storage in front of every step. Also assume there is sufficient input raw material at Step 1.
