Cycle time (software)
Cycle time has different meanings and should not be confused with takt time or lead time. As the name suggests, it contains time as a unit of measure and relates to e.g. CPU cycle time (Cycles per instruction) in computer context.

In software engineering however, cycle time is a software metric and a rough measure of process speed in context of development, specifically in agile software projects.
