Explanation
Conducting a PI planning event is an example of applying cadence and synchronization in SAFe. Cadence is a regular and predictable pattern of events that provides a rhythm for development. Synchronization is the alignment of multiple perspectives and activities within a cadence. PI planning is a two-day event that occurs at the beginning of every Program Increment (PI), which is typically an 8-12 week timebox. PI planning brings together all the teams in an ART to align on a common vision, identify dependencies, plan features, establish objectives, and commit to a plan for the next PI.
