A Program Increment (PI) is a timebox during which an Agile Release Train (ART) delivers incremental value in the form of working, tested software and systems. PIs are typically 8–12 weeks long. The most common pattern for a PI is four development Iterations, followed by one Innovation and Planning (IP) Iteration.
A Program Increment is to an ART (or Solution Train) as an Iteration is to the Agile Team. In other words, the PI is a fixed timebox for building and validating a full system increment, demonstrating value, and getting fast feedback. Each PI uses cadence and synchronization ...
