- Méthodologie Agile, Remue-méninges, Créativité, Collaboration interfonctionnelle, Pensée conceptuelle, Innovation, Techniques de résolution de problèmes, Amélioration des processus, Travail d'équipe
Objectif :
Comment il est utilisé :
- Participants metaphorically wear different colored hats: White (facts & information), Red (emotions & intuition), Black (caution & critical judgment), Yellow (optimism & benefits), Green (creativity & new ideas), and Blue (contrôle des processus & overview). The group focuses on one hat at a time.
Avantages
- Encourages thorough exploration of a topic from multiple viewpoints; Reduces conflict by separating ego from performance; Fosters focused and productive discussions; Promotes creative thinking and critical evaluation in a structured way.
Inconvénients
- Can feel artificial or overly structured if not facilitated well; Requires discipline from participants to stick to the designated hat; May take time for teams to become proficient in its use.
Catégories :

Idéal pour :
- Facilitating effective group discussions, exploring different perspectives on an issue systematically, and making more well-rounded decisions.
The Six Thinking Hats methodology can be employed in various industries, including product design, healthcare, education, and corporate strategy, allowing teams to tackle problems or innovate in a structured manner. This approach is particularly effective during brainstorming sessions, project reviews, and product development phases, where collaboration and comprehensive analysis are required. For example, in a design team developing a new consumer electronic device, members might use the White Hat to present market research data on user preferences, switch to the Red Hat to express feelings about design aesthetics, utilize the Black Hat to identify potential manufacturing limitations, and then adopt the Yellow Hat to envision the advantages this product could offer to customers. This technique is often initiated by team leaders or project managers, but it thrives on participation from diverse roles across an organization, including engineers, designers, marketers, and end-users. Its structured nature encourages all participants to contribute their viewpoints without falling into conflicts over personal opinions, as the focus transitions systematically from one aspect to another, fostering an atmosphere of respect and collaboration. Such meetings can lead to more innovative outcomes, as the Green Hat invites out-of-the-box thinking and the exploration of unconventional solutions. Companies that have successfully implemented this methodology report clearer decision-making processes, increased team alignment, and ultimately more robust product offerings that address various stakeholder needs.
Principales étapes de cette méthodologie
- Introduce the issue to be discussed.
- Wear the White Hat: Focus on facts, data, and information relevant to the topic.
- Wear the Red Hat: Share emotions, intuitions, and gut feelings regarding the issue.
- Wear the Black Hat: Discuss potential risks, obstacles, and negative aspects.
- Wear the Yellow Hat: Explore benefits, advantages, and positive outcomes.
- Wear the Green Hat: Brainstorm creative solutions and new ideas.
- Wear the Blue Hat: Guide the process, summarize discussions, and outline next steps.
Conseils de pro
- Rotate the hat order based on the phase of discussion, ensuring fresh perspectives emerge at critical stages.
- Assign specific roles to participants for each hat to enhance engagement and accountability during discussions.
- Document the outputs from each hat systematically to create a comprehensive record for future reference and analysis.
