Consider the five process designs represented in the table below. For each design, the amount of time (in seconds) that a unit spends at a workstation is provided in the associated cell. Assuming all of the above designs are operating in steady state, if the market demand is for 7 units per minute, which of the above designs maximizes throughput with the fewest number of workstations? Select one: a. Design 1 b. Design 2 c. Design 3 d. Design 4 e. Design 5
