The business must depend on the team's capabilities to do any meaningful planning. This is because the team's capabilities determine the amount and complexity of work they can handle during a Program Increment (PI). SAFe emphasizes the importance of understanding the team's capacity and skills to ensure that the planning is realistic and achievable1.
During PI planning, teams create PI objectives they intend to accomplish in the upcoming PI. These objectives are based on the team's understanding of their capacity and the features they need to deliver. The process requires estimating and planning, knowledge of the team's capacity, analysis of upcoming features, defining stories for the Team Backlog, and summarizing the information into simple business terms everyone can understand2.
Furthermore, the Release Train Engineer (RTE) plays a vital role in facilitating PI planning events, which align all the teams on the Agile Release Train (ART) to a shared mission and vision. The RTE helps ensure planning readiness, which includes leadership and team preparedness for the event (content readiness), part of which is understanding the team's capabilities1.
