Lead time vs cycle time

[ashwineec]

Lead time -> time from inception to delivery
cycle time -> from one process to another ( requirement to implemenation)
Is my understanding correct?
Cycle time sometimes referes to time from requirement to deployment then lead time and cycle time is same.
Can you please clarify ?

Clear to good extent -
Lead time : Time between user story is on boarded in "Todo" to "Deployed" stage
Cycle time : Actual processing time - say "Analysis" to "Deploy"

So cycle time doesnt consider the waiting time in "Todo" thats the main difference?

Yes at top level you can say, for Cycle time you define the process start and end point and you capture time in between, whereas lead time start with customer and end at customer.

I do not expect PMI-ACP exam differentiating it, and many time exam may use these two terms interchangeably
