Include step-by-step guidance on setting the stage, gathering data, generating insights, deciding on actions, and closing the session. Emphasize techniques to foster psychological safety, encourage participation from [QUIET TEAM MEMBERS], and avoid common pitfalls like [BLAME GAME]. Provide examples of icebreakers, timeboxing strategies, and tools (e.g., Miro, FunRetro) for [REMOTE/HYBRID TEAMS]. End with a checklist for follow-up accountability.
