The Team Radar is a nice retro activity. I provide some tips and improvements in this blog post.
Agenda with a team radar (spider net) example, to describe the method
A wall / flipchart for the team radar with a central point and four pre-drawn arrows in the four cardinal directions. (A paper flipchart is ideal, because you can simply count ten squares to
draw each scale from 0-10)
Improvement: Draw eight arrows in advance
Tape (for the flipchart and the agenda)
Set the stage
Gather Data (15-30 minutes)
Collect "attributes for effective work in a Scrum team"
Pick a general topic for the attributes
Whole Team, one team member writes the attributes on Post-Its
Find 5-8 attributes, reduce attributes with Dot-Voting if needed
Draw the additional direction arrows
Let every team member vote (draw a stroke on the scale from 0-10) for each attribute
Improvement: Reach independency of votes, e.g. collect individual votes on Post-Its and draw them together with a team member
Draw the spider net (ask the team which point to use, e.g. low, high, middle, median)
Tipp: draw a circle around the votes to visualize spread
Suggestion: Use the most inner point for the spider net
Generate Insights (20-30 minutes)
Open discussion with a short timebox: "What catches your eye?" Lead the discussion to "interesting findings", e.g. spread, outliers, high or low votes,
Issue: Depending on the question or the participants, this could immediately lead to deep analysis. You may have to adapt the further agenda then
Identify with the team topics to analyze further (totally dependent on the wish of the team, this might be DoT Voting)
Use pairs/small team to create ideas for measures, Then merge the ideas in the whole group
Tipp: visualize them next to the attribute on the team radar
Issue: How to get "good" measures? This is an area for further improvement.
Decide what to do (5-10 minutes)
If you have several measures, simply do a Dot-Voting and let the team pick the top 1-3 measures "As a team, we want to try next sprint:".
Improvement: You may rewrite the measure to fulfill the SMART-criteria
Let the team decide on an owner for each measure "Who cares for it next Sprint"
Alternative: The teams puts the tasks on the board
Improvement. Add a hypothesis (what you want to achieve) to each measure.
