Ideation

  • Understand what ideation means in Design Thinking
  • Discover techniques to generate ideas
  • Learn how to organize a brainstorming and a brainwriting session
  • Apply the Crazy 8 technique
  • Use mind mapping to structure ideas
  • Select and converge ideas to choose the best one for prototyping

The ideation phase aims to generate a wide range of ideas to solve a problem identified in the definition phase.

It includes two steps:

  1. Divergence → Generate as many ideas as possible, without judgment
  2. Convergence → Filter and select the most relevant ideas

A group session where participants freely share ideas.

Rules for effective brainstorming:

  • A facilitator leads the session
  • Friendly atmosphere (tools available, relaxed environment)
  • Time-limited session (max 45 minutes)
  • Group of 8 to 10 participants
  • All ideas are welcome, even wild ones
  • No criticism allowed
  • Final synthesis to group and refine ideas

A written version of brainstorming, where ideas are written down and shared anonymously.

Methods:

  1. Brainwriting Pool: Everyone writes ideas on sticky notes, then picks others’ notes and adds on.
  2. Brainwriting 6-3-5: 6 people write 3 ideas in 5 minutes, then pass their sheet to another participant to improve or expand ideas.

Advantages:

  • ✅ Reduces fear of judgment
  • ✅ Gives everyone a voice
  • ✅ Helps refine and build on ideas

A fast and visual technique to generate 8 ideas in 8 minutes.

Steps:

  1. Fold a paper into 8 sections
  2. Each participant sketches one idea per box (1 min per idea)
  3. Everyone shares their ideas
  4. A voting round selects the best concepts

💡 Ideal for visual solutions like app interfaces.


A visual diagram that organizes ideas hierarchically.

How to do it:

  1. Place the central problem in the center
  2. Connect main ideas as branches
  3. Expand each idea with sub-branches
  4. Group and prioritize the ideas
Recommended tools:
  • XMind
  • MindMeister
  • Coggle
  • Whiteboard + sticky notes

After generating lots of ideas, it’s time to narrow them down to select the best one to prototype.

  1. Dot Voting
  • Each participant votes on their favorite ideas
  • Most-voted ideas move to the next phase
  1. The 4-Category Method

Ideas are categorized as:

  • Rational Choice → The most logical
  • Favorite Choice → Most liked by the group
  • Consensus Choice → Agreed upon by most
  • Risky Choice → Bold, innovative, but uncertain

Goal: Select the strongest, most viable idea to prototype and test.


The ideation phase helps generate a wide range of ideas before selecting the most relevant one.
It’s divided into two steps: Divergence (creativity) and Convergence (selection).

  • Brainstorming → Free group sharing
  • Brainwriting → Silent writing and idea building
  • Crazy 8 → 8 quick sketch ideas in 8 minutes
  • Mind Mapping → Visual idea organization
  • Selection Methods → Dot voting or 4-category sorting

The goal is to end up with one strong, viable idea for the next phase: prototyping!
