Manage Change Through Collaboration and Team Work

The definition of done is the shared, written standard that every piece of work must meet before it counts as complete, covering the quality, testing, documentation and release conditions that make an increment usable.

A retrospective is a regular, structured meeting in which a team examines how it worked over the last period, decides what to change, and commits to one or two concrete improvements for the next one.

Incident management is the service-management practice of restoring a disrupted IT service to normal operation as quickly as possible, through a defined process of logging, categorising, prioritising, resolving and closing each incident, separate from the later work of finding and fixing its root cause.
