Assess how to continue with last retro's actions Source: Sven Winkler
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:
Find the source of problems whose origins are hard to pinpoint and lead to endless discussion Source: Henrik Kniberg
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.
Asking and answering go around the team circle - an excellent way to reach consensus Source: Agile Retrospectives
Everyone sits in a circle. Begin by stating that you'll go round asking questions to find out what you want to do as a group. You start by asking your neighbor the first question, e.g. 'What is the most important thing we should start in the next iteration?' Your neighbor answers and asks her neighbor a related question. Stop when consensus emerges or the time is up. Go around at least once, so that everybody is heard!
