QuestionQ360

Delivery

A customer-service line has a throughput of 200 tickets. Employees raise the tickets, and each 8-hour shift has an average of 50 tickets in progress.

What is the cycle time for resolving a ticket?

  • A 0.25 hour
  • B 1 hour
  • C 2 hours
  • D 4 hours
Explanation

By Little’s Law, cycle time equals average work in progress divided by throughput rate. A throughput of 200 tickets per 8-hour shift is 25 tickets per hour; with 50 tickets in progress, the cycle time is 50 ÷ 25 = 2 hours.
