Six Thinking Hats is a system designed by Edward de Bono which describes a tool for group discussion and individual thinking involving six colored hats. “Six Thinking Hats” and the associated idea parallel thinking provide a means for groups to plan thinking processes in a detailed and cohesive way, and in doing so to think together more effectively.
There are a total of six colored hats. Each hat help us focus on our thinking direction. I used the hats in the following sequence – White, Red, Yellow, Black, Green and Blue. I got the team to spend about 5 minutes of silent brainstorming and post-it writing before another 5 mins of going through the post-it notes.
White Hat – Fact and information about the iteration that has just passed. Similar to gathering data stage. Defects and stories delivered not delivered are part of the white hat. Planned leave and unplanned leave can also be part of the white hats.
Red Hat – How each of the team member feel during the iteration. The feeling does not need to be justified nor explained. We will not go into details on why and who wrote it for this hat.
Yellow Hat – What went well for the iteration. What are the good practices that we should continue to practice.
Black Hat – What did not go well for the iteration. What are the areas that the team should take note of for subsequent iterations.
Green Hat – What are the new idea/practices that the team can consider to adopt. Any proposal to change existing practices.
Blue Hat – What are the action items pertaining to Yellow Hat, Black Hat and Green Hat and who should own it with a timeline.
