Welcome to our advent calendar! Throughout December, we're exploring the behind-the-scenes aspects of product creation. Today, we're diving into a key ritual: the design critiquesThey boost product quality, accelerate decision-making, and strengthen team cohesion. In this article, discover the critical design methodology and download a ready-to-use template to integrate it permanently into your practice.

What is critical design?

Critical design is simple: team members (designers, developers, PMs and stakeholders) meet to provide structured feedback on ongoing design work.
This is not a simple review: it is a collaborative session where solutions are evaluated against user needs and business objectives.

Why does it work?

• Promotes a culture of constructive feedback.

• Improves quality through the plurality of perspectives.

• Strengthens coherence between projects and mutual understanding.

A designer on my team recently shared:

"Since Aki introduced critical design, this format has become an integral part of my practice and will accompany me throughout my career."
Another added:
"His critical design template has become a true standard within our team."

Concrete benefits

Critical design transforms the way teams work:

• Faster decisions Detecting a problem early saves considerable time compared to late discovery.

• Increased coherence : seeing the work of others reinforces the harmonization of components and interactions.

• Constructive culture : feedback becomes normalized and less dramatic.

• Shared understanding : varied perspectives refine the solutions.

What design critics are not

• Not from user search They evaluate solutions, not behaviors.

• Not brainstorming : ideation takes place upstream.

• Not intended for end users : only project teams participate.

When to organize a design critique?

They are useful at all stages, but particularly during key milestones:

Phase Discover

• Project launch

• Evaluation of initial explorations

Phase Iterate

• Refining the concepts

• Pre-development, before the handoff

💡 Tip: early enough to influence, but late enough to assess a clear intention.

Prepare a critical design

1. Choose the participants (3 to 8 people).

2. Prepare the background slides : logic, objectives, research insights.

3. Create a collaborative space (Miro, FigJam) upstream.

Tips for the presenter

• Create a supportive environment where every voice matters.

• Encourage a period of silent feedback to avoid conformity.

• Guide the discussion without imposing.

• Let the group challenge decisions, and accept not defending everything immediately.

Typical procedure

Understanding the roles

Facilitators / Presenters

• Explain the project, the rationale, and clarify expectations.

• Listen without becoming defensive.

Critics

• Provide clear and actionable feedback.

• Identify problems, questions, and successes.

The Rose/Thorn/Bud framework

A simple, efficient and balanced structure:

???? Rose : what works well
???? Thorn difficulties, risks
???? Bud opportunities, avenues to explore

Making critical design a team standard

When they become regular, their effects extend beyond the projects:

• improved reuse of components,

• overall understanding of the product,

• enhanced coherence

• natural diffusion of good practices.

Conclusion

Critical design sessions are moments where collaboration and evaluation converge. When well-structured, they elevate design quality, foster empathy, and accelerate decision-making. By making them a team ritual, you create an environment where every voice matters and every project progresses faster—and better.
