Summary Introduction
Case summary:
Person HR the manager of the metropolitan branch made an attempt to analyze the driving license renewal operations. The various steps and the time taken for each of them are analyzed.
He identified that the work was divided unequally between the workers. This led to long queues during peak periods. He was under severe pressure to increase the productivity while satisfying the incoming demand.
To determine: The maximum number of applications per hour that can be processed.
