PI planning | Glossary

Definition:

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.‘ It’s a fixed timebox for building and validating a full system increment, demonstrating value, and getting fast feedback. Each PI uses cadence and synchronization to:

  • Facilitate planning
  • Limit Work in Process (WIP)
  • Summarize newsworthy value for feedback
  • Assure consistent, Program Level retrospectives

Jidoka | Glossary

Definition

Jidoka is the policy of halting the production or development whenever there’s a fault or bug cropping up, the next step is to fix the problem and find the reason for the problem, thereby making sure it doesn’t occur again. This is considered to be a highly beneficial policy as it helps in increasing the quality of work.

Origin

The concept of jidoka originated in the early 1900s when Sakichi Toyoda, founder of the Toyota Group, invented a textile loom that stopped automatically when any thread broke.
