Saturate and Group

Purpose

Saturate and Group is a rapid synthesis technique for making sense of qualitative research data. By externalising every observation, quote, and insight onto a shared surface and then grouping related items, teams move from scattered data to coherent themes that drive design decisions.

At a glance

• Group size: 3–8
• Duration: 30 minutes
• Difficulty: Low to moderate
• Facilitation style: Individual sharing followed by collaborative clustering
• Setting: Large wall with plenty of sticky-note space

How to run

1. Saturate (10 min): Each team member writes one observation, quote, or insight per sticky note from their research. Cover the wall. Aim for 50–100+ notes total.
2. Share highlights (5 min): Each person briefly narrates 3–5 of their most surprising or important notes.
3. Group silently (10 min): Everyone stands at the wall and moves notes into clusters based on affinity. No talking — let the groupings emerge organically. If someone moves your note, let it go.
4. Name the clusters (5 min): Once clusters stabilise, the team discusses and names each theme with a header note.

Materials needed

• Large wall or multiple flip charts
• Sticky notes (ideally one colour per researcher)
• Markers
• Header cards or larger sticky notes for cluster names

Pitfalls & common mistakes

• Too few notes: If you have fewer than 30 notes, the clustering will be trivial. Push for more data.
• Premature categorising: Don’t decide categories before clustering. Let them emerge.
• One person dominates the wall: The silent grouping phase prevents this — enforce it.
• Ignoring outliers: Notes that don’t fit any cluster may be the most interesting insights.

Inclusion & accessibility

• Read clusters aloud for visually impaired participants.
• Allow digital sticky notes (Miro/Mural) for remote participants to contribute equally.
• Ensure wall height is reachable for wheelchair users — use a lower section or table.

Variations

• Affinity diagram: A more formal version with stricter bottom-up grouping rules.
• Digital saturate and group: Use Miro or FigJam for distributed teams.
• Speed saturate: Limit to 5 minutes of posting and 5 minutes of grouping for a faster version.

When NOT to use this

• When you have quantitative data that needs statistical analysis, not thematic grouping.
• When only one person did the research — individual synthesis methods may be more efficient.
• When the team has not done primary research and would be grouping assumptions.
