Consider a simple process where work flows from Activity A to Activity B to Activity C to Activity D. Activity A takes 3 minutes and is performed by Aaron. Activity B takes 5 minutes and is performed by Aaron and Betty together. Activity C takes 4 minutes and is performed by Betty and David together. Activity D is performed by David and takes 3 minutes. What is the bottleneck of the process?

(a) None of these
(b) Activity B
(c) Betty
(d) Aaron
(e) Activity C

The correct answer is the option B: Activity B.

Explanation:

First of all, the term ''bottleneck'' in the management area refers to the activity or process in a chain of processes that its limited capacity reduces the capacity of the chain in its whole.

Once said that, in the case presented, where there are four workers and two of them have to do two differents tasks then the activity consider the bottleneck of the process will be the one in where one person does an activity after another and that reason makes that person delates more in working. That is the case of the activity B, where Aaron has to work again after the first activity and that takes him and Betty five minutes full, while in the other case where Betty works with David they only take four minutes, so therefore that the activity B is the bottleneck of the process.
