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.
Find the source of problems whose origins are hard to pinpoint and lead to endless discussion Source:
Write the problem you want to explore on a sticky note and put it in the middle of a whiteboard. Find out why that is a problem by repeatedly asking 'So what?'. Find out the root causes by repeatedly asking 'Why (does this happen)?' Document your findings by writing more stickies and showing causal relations with arrows. Each sticky can have more than one reason and more than one consequence Vicious circles are usually good starting points for actions. If you can break their bad influence, you can gain a lot.
Create actions based on how much control the team has to carry them out Source:
Diana Larsen who adapted it from 'Seven Habits of Highly Effective People' by Stephen Covey and Circle of Influence and Concern' by Jim Bullock
Prepare a flip chart with 3 concentric circles, each big enough to put stickies in. Label them 'Team controls - Direct action', 'Team influences - Persuasive/recommending action' and 'The soup - Response action', from innermost to outermost circle respectively. ('The soup' denotes the wider system the team is embedded into.) Take your insights from the last phase and put them in the appropriate circle. The participants write down possible actions in pairs of two. Encourage them to concentrate on issues in their circle of influence. The pairs post their action plans next to the respective issue and read it out loud. Agree on which plans to try (via discussion, majority vote, dot voting, ...)
Prepare 3 flip chart papers titled 'Helped', 'Hindered', and 'Hypothesis' (suggestions for things to try out). Ask participants to help you grow and improve as a facilitator by writing you sticky notes and signing their initials so that you may ask questions later.
