Problem:
A government department that deals with passport applications receives applications on a daily basis. On receipt, applicants' details are captured on the relevant system, such as the National Population Register.
The department is always busy, and processes an average of 3000 applications per eight-hour day. During a recent inspection by the Minister of Home Affairs, it emerged that at least 7 500 applications were in progress or waiting to be processed. Under normal circumstances, it should take 15 minutes to process an application.
Question: Calculate the throughput efficiency of the process.
