Place a circle or sphere in the middle of a free space. Let the team gather around it. Explain that the circle is the center of approval: If they agree to a statement they should move towards it, if they don't, they should move as far outwards as their degree of disagreement. Now read out statements, e.g.
I feel I can talk openly in this retrospective
I am satisfied with the last iteration
I am happy with the quality of our code
I think our continuous integration process is mature
Watch the constellations unfold. Afterwards ask which constellations were surprising. This can also be a closing activity (#53).
Draw a table with 3 columns. Head the first one 'Destination', the second one 'Delay' and the last one 'Announcement'.
Introduce the scenario: 'You are at a train station. Where is your train going? (It can be anything, a fictional or a real place.) How much of a delay does the train currently have? And what is the announcement? Why is there a delay? (This can be a real reason or modeled after the typical announcements.)'
Each team member fills out 3 sticky notes, 1 for each column. Going around the circle, each team member posts their notes and explains briefly, why they're going to destination X and why there's a delay (or not).
Trains and train delays are very familiar in Germany. Depending on your country and culture you might want to pick a different mode of transportation.
Introduce SMART goals (specific, measurable, attainable, relevant, timely) and examples for SMART vs not so smart goals, e.g.'We'll study stories before pulling them by talking about them with the product owner each Wednesday at 9am' vs. 'We'll get to know the stories before they are in our sprint backlog'. Form groups around the issues the team wants to work on. Each group identifies 1-5 concrete steps to reach the goal. Let each group present their results. All participants should agree on the 'SMART-ness' of the goals. Refine and confirm.
Let team members appreciate each other and end positively Source: Agile Retrospectives who took it from 'The Satir Model: Family Therapy and Beyond'
Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
