PeopleCert DevOps-Foundation Question Answer
How do you define Wait Time?
Lead time minus cycle time
Cycle time minus lead time
Lead time plus cycle time
Cycle time multiplied by lead time
Wait Timeis the time work spends waiting between process steps—wasted, non-value-added time.
Mathematically,Wait Time = Lead Time – Cycle Time
Lead Time:Time from work request to delivery.
Cycle Time:Time spent actively working on the item.
Why is this important in DevOps?
Identifying and reducing wait time (waste) is central to Lean/DevOps, directly improving flow and reducing delays.
Extract-style reference:
“Wait time is calculated as the difference between lead time and cycle time—highlighting bottlenecks in the value stream.”
—DevOps Handbook
PeopleCert DevOps Foundation v3.6:Wait time is a core Lean concept for optimizing flow.
