During which phase are Backlog grooming or Refinement sessions typically held?

Backlog grooming, also known as backlog refinement, sessions are primarily held during the Build phase of a project. This is the stage where the development team actively works on turning the product backlog into workable user stories and tasks. During these sessions, teams assess the priority of items in the backlog, clarify requirements, and break larger items into smaller, actionable pieces that can be tackled in future iterations. This ensures that the team is well-prepared for the upcoming work and helps maintain a clear focus on delivering value to users.

While backlog grooming can occasionally take place before a new phase begins, the Build phase is where it plays a crucial role in keeping the team's progress organized and aligned with project goals.
