Conducting a PI Planning event is an example of applying cadence-based synchronization in SAFe. A PI Planning event is a two-day face-to-face or virtual meeting where all the members of an ART and Solution Train collaborate to align on a common vision, mission, and backlog, and plan the work for the next Program Increment (PI). A PI is a fixed timebox of 8 to 12 weeks that provides a regular cadence for delivering value. The PI Planning event is synchronized across all the teams and trains in the portfolio, and it occurs at the beginning of every PI. The PI Planning event enables the ART and Solution Train to achieve alignment, collaboration, synchronization, and commitment, as well as to identify and address risks and dependencies. References: = PI Planning - Scaled Agile Framework, Exam Study Guide: SP (6.0) - SAFe® Practitioner
