The interval of inactivity between stages, characterized by delays and queuing.
— Flow Engineering, Steve Pereira and Andrew Davis
Wait Time
3 of our books define this term — and their definitions are worth reading side by side.
The wait time for a given resource is the percentage that resource is busy, divided by the percentage that resource is idle.
— The Phoenix Project, in “Chapter 20”, Gene Kim, Kevin Behr, and George Spafford
wait time = queue size/processing rate
— A Seat at the Table, in “3 - A Nimble Approach To The Table”, Mark Schwartz
