Using 6 Thinking Hats For Better Design

A design critique session can be tough. Some people don’t feel comfortable enough to give an honest opinion and limit themselves to giving positive feedback. Others will only observe the negatives. And most folks base their critique on their own biased aesthetic viewpoint  rather than focusing on the purpose of the design (form follows function, remember?). These and a number of other reasons can turn a design critique session into an endless back-and-forth conversation.

Enter Six Thinking Hats….

To keep the group focused on provide feedback based on different views of the same situation minus the conflicts, I’m using a methodology created by Edward DeBono called Six Thinking Hats. It is also known as the Black Hat session, as the black hat is really important to it, as I’ll describe later.

The core of the Six Thinking Hats is to help people to change their own thinking process. When giving feedback we tend to be biased, too positive or too negative and we usually forget to see all aspects of the situation.

To use this method, we divide the group into six different roles, six different “thinking hats”: 


  • White:  focus on facts. “This information is not clear to me.”

  • Yellow: is the positive view. It focus on the benefits. “It was very easy to find the search field.”

  • Black: devil’s advocate. Focus on risks and weaknesses. “The is not enough color contrast and is really hard to read the text on this graphs.”

  • Red: provides emotional feedbacks based on intuition. “I don’t like the animations, it makes me feel distracted.”

  • Green: brings news alternatives and concepts not explored yet. “What about a tooltip to help users to understand the abbreviations on this table?”

  • Blue: control. It helps the team to focus on the process and ensures that the guidelines are followed.

The Black hat is special to this process. To create the best design we should have a high level of auto-critique. However, it can be hard to to pinpoint your own gaps when you are the only one thinking through the design. The Black hat will ensure that risks, weakness and critical issues will be taken into consideration in an open and safe environment.

Running the session

This session can be run whenever you feel that user feedback is needed to validate your design ideas to move ahead with development, engage the team in the design process or make decisions, which means - always.

The session should be time boxed to 60-90 min. You will need Post-its, pencils, paper hats (or tags) and a printed version of the interfaces that need feedback (put them visibly up on a wall for people to take a close look).

Ideally, and to keep it fun, colourful paper hats can be used to indicate each person’s role during the session. You can also use tags and write the color name on each of them.

Distribute the colours, explain what they mean, and give the team 15 minutes to look at the designs. They can provide as much feedback as they want, but limited to one piece of feedback per post-it. Then post their notes around the designs, or you can help them to group the feedback in categories. 


Next, everyone is invited to present their feedback to the group. If your group is large, and you have more than one person per role, ask them to pair on their presentations.

At the end of the session you will have tons of feedback from different perspectives and will be able to prioritise issues and define (or confirm) the right path for your design vision on the project.

An extra benefit is to create a collaborative environment where everyone is responsible for the User Experience. A open session like that, with the participation of your team, real users and stakeholders creates a balanced environment that considers the user needs, the business purpose and the right technology to create great products.

Thoughts? Which tools and techniques do you use to collect meaningful feedback and generate discussion around design?



Experiência do Usuário: uma introdução.

No dia 4 de abril eu e a Natalia Arsand apresentamos uma introdução à prática de Experiência do Usuário no evento de 10 anos do GUMA-RS. A apresentação é baseada no nosso conhecimento da prática aplicada ao desenvolvimento ágil de software.

O público fez perguntas muito interessantes sobre como introduzir a prática de experiência do usuário em empresas e equipes que ainda não definiram o usuário como centro de sua estratégia (ou nunca trabalharam com UX Designers), então aqui vão alguns dos livros que citei e que abordam o tema:

Undercover User Experience Design, por Cennyd Bowles e James Box. 

Agile Experience Design: a digital designers guide to being Agile, por Lindsay Ratcliffe e Marc MacNeill.

The User Experience Team of One, por Leah Buley.

Lean UX, por Jeff Gothelf  e Josh Seiden.

E aqui está a nossa apresentação. :)
