Step-by-step explanation:
The term referenced in the question pertains to an event in Agile methodology known as the Program Increment (PI) planning meeting, a key event in the Scaled Agile Framework (SAFe). This pivotal event is comparable to a cadence-based, face-to-face gathering that acts as the central alignment point for Agile Release Train (ART), which is a large group of agile teams that plan, commit, and execute together. The purpose of the PI planning event is to align all the teams to a shared mission and vision. By bringing together everyone involved, it ensures that each team is aware of the objectives and can work in synchronization to achieve the goals, effectively functioning as a large group of people who gather together for a collaborative activity with a clearly defined duration.
