Review the work, find the root causes, extract the learning.
Teams work through a series of tailored retrospective questions to review their work from multiple angles, digging into root causes and extracting the key learnings.

Teams gain a clear picture of what happened and why, with concrete learnings and actions to carry forward.

Agree the period you are looking back on with the team leader in advance, then work the group through four questions to understand what happened, why, and what to carry forward. Push past surface answers to the dynamics beneath the outcomes.
Brief the group at the start: we are looking at this period, and the aim is to understand what happened, why, and what we can take forward. Then work through four questions in sequence, giving people time to write individually before discussing as a group.
What went well? Capture real successes: outcomes achieved, moments of strong collaboration, decisions that held up. Push for specifics, since 'the way we managed handovers between the two teams during the final week' is more useful than 'the launch.' What was difficult? Name the challenges, blockers, and moments of friction, framed as what we would want to avoid repeating. What impact did we make, and what changed as a result of this team's work? And what have we learned, drawing on the first three: given what went well and what was difficult, what do we now know that we did not before, about our work, our team, or how we operate together?
Then identify two or three clear themes and name them explicitly. The retrospective is most valuable when it surfaces the dynamics beneath the outcomes, so push past surface answers with questions like 'what made that difficult?' and 'how were we operating as a team at the time?' The goal is root causes and real learnings.
Use Retrospective when a team wants to review a project or period and pull real learning from it. Structured questions look at what happened and why, digging past surface accounts to root causes and leaving the team with clear themes and actions.

Using this tool with a skilled facilitator means that discussions are focused, time is used efficiently, and the group moves toward consensus, making the session productive and impactful.
