During which iterative ceremony should someone obtain feedback?

The iteration demo is specifically designed to showcase the work completed during the iteration to stakeholders and gather their feedback. This ceremony occurs at the end of an iteration, allowing team members to present their deliverables and receive insights that can inform future work. The feedback obtained during this demo is invaluable as it helps teams understand how well they have met the needs of the stakeholders, what changes might be necessary, and how to improve in subsequent iterations.

While the other ceremonies such as the daily stand-up, iteration planning, and retrospective have their own purposes, they do not primarily focus on obtaining feedback from stakeholders regarding the product increment. The daily stand-up is more about coordinating team activities and addressing immediate roadblocks. Iteration planning is focused on planning the goals and tasks for the upcoming iteration. The retrospective, on the other hand, is about reflecting on the team's process and how they can improve their collaboration and efficiency, rather than gathering feedback on the product itself. Therefore, the iteration demo stands out as the ideal ceremony for obtaining feedback.
