How often should a retrospective be conducted in PRINCE2 Agile?

In PRINCE2 Agile, conducting a retrospective at the end of each iteration or sprint is essential for continuous improvement. This practice aligns with Agile principles, emphasizing the importance of regular reflection and assessment of team processes and workflows. By holding retrospectives at the end of each iteration, teams have the opportunity to evaluate what went well, what challenges were faced, and how they can enhance their practices moving forward. This feedback loop is critical for fostering an adaptive environment where team members can openly discuss issues, propose solutions, and implement changes in subsequent iterations, ultimately leading to better productivity and project outcomes.

In contrast, conducting a retrospective only at the end of the project limits opportunities for learning and adaptation. Waiting for a year to have such discussions would not provide timely insights into team dynamics and project progress. Additionally, relying solely on the discretion of the team leader without a fixed schedule may lead to inconsistencies and missed opportunities for improvement, as the rhythm and structure provided by regular retrospectives would be lost. Thus, holding retrospectives at each iteration effectively supports the Agile approach of responding to change and continuously improving the work process.
