Final answer:
Retrospective meetings should be held at the end of each Sprint to allow the Development Team to inspect and adapt its processes, ensuring continuous improvement. These regular meetings contribute to a spiral design process and allow for iterative development and refinement. Action should be taken on feedback received to improve team performance continuously.
Step-by-step explanation:
Retrospective meetings should be held at the end of each Sprint. This is because they serve a vital role in the agile development process, enabling the Development Team to inspect and adapt its processes. By doing so, the team can achieve continuous improvement, assess what worked and what didn't, and discuss possible changes for future sprints.
It's crucial that these meetings take place regularly to ensure that team dynamics, processes, and tools are continually evolving and improving. This approach creates new meanings and perspectives that help to refine future interactions. Retrospectives are a core element of the spiral design process which emphasizes iterative development and refinement.
Finally, team members should take action on the feedback received in retrospective meetings. This involves making an effort to improve upon any weaknesses identified, asking for feedback regularly, and ensuring that they stay on track with their work plans. This practice is integral to maintaining a productive and forward-moving team environment.
