Synthesis & Clustering

How to turn raw research into groups, identify archetypes, and avoid common synthesis traps.

Synthesis & Clustering

Synthesis turns research data into digestible patterns. Start by extracting behaviors, motivations, and constraints from your data and using clustering to identify personas.

Common approaches

  • Affinity mapping: group quotes and evidence on a board
  • Quantitative clustering: use analytics or survey data for behavioral buckets
  • Hybrid method: annotate data, then run clustering and iterate

Practical exercise

  • Create an affinity map with 20–50 research notes and identify 3–5 clusters.
  • For each cluster, write a one-sentence archetype label.

Avoid these mistakes

  • Designing personas from a single interview
  • Mixing demographic-based segments with behavioral segments indiscriminately
