Assess how to continue with last retro's actions Source:
Create a table with 5 columns. The first column lists last retro's action items. The other columns are headed 'More of', 'Keep doing', 'Less of' and 'Stop doing'. Participants place 1 sticky note per row into the column that states how they want to proceed with that action. Afterwards facilitate a short discussion for each action, e.g. asking:
Collect some news headlines in advance and take them to the retrospective to serve as examples. Try to gather a mixture of headlines: factual, opinion, review. Place the headlines where everyone can see them. Hand out sticky notes. Give team members 10 minutes to come up with their own headlines describing newsworthy aspects of the sprint. Encourage short, punchy headlines. Stick the completed headlines to a whiteboard. If any cover the same news item, combine them. If any are unclear, ask the reporter for details. Vote on which news items to discuss and analyse in more depth.
