Affinity Diagram Template and Example
A structured framework to organise complex qualitative data and brainstormed ideas into coherent, actionable themes.
§1Understanding the Affinity Diagram
The affinity diagram is a cornerstone of qualitative analysis, transforming the chaos of unstructured feedback into a logical, hierarchical structure.
During the early phases of any project, requirements gathering exercise, or broad brainstorming session, teams invariably generate vast quantities of disparate data points. The affinity mapping process provides a systematic method to group these unstructured inputs—traditionally recorded on sticky notes—based purely on their natural relationships to one another.
Used extensively in Six Sigma, user experience (UX) research, and general project management, this framework allows stakeholders to bypass individual cognitive biases and uncover the genuine, holistic themes residing within large datasets.
Contents§2Blank Template Structure
The blank template provided in this toolkit is designed for immediate deployment in your project workshops, acting as a structured canvas for your team's raw ideas.
The resource features a clear header block to establish the project context, along with a primary focal question to anchor the team's thinking. Below the header, six initial grouping areas are provided to help spatial organisation during the session.
§3Worked Example: Mary's Consulting
To demonstrate the practical application of this tool, we have included a completed, real-world example based on a web development project.
In this scenario, a project team gathered to establish the foundational success criteria for a new corporate website. The core question posed to the room was: "What makes the new marysconsulting.com website successful?"
Following a rapid ideation phase, the raw sticky-note ideas were synthesised and grouped into six distinct thematic clusters:
| Theme | Synthesised Requirements |
|---|---|
| Performance / Speed | Strict page load limits (< 2.5s), global CDN delivery, structural stability (no layout shifts), and rigorous image optimisation. |
| Content Quality | Strong portfolio case studies, maintenance of a consistent firm voice, regular content updates, and absolute freedom from typographic errors. |
| User Experience | Frictionless navigation, a mobile-first design architecture, highly visible calls-to-action, and a high-functioning internal search engine. |
| Brand Identity | A premium visual aesthetic (reflecting a 'Fortune 500' posture), distinctive positioning against direct peers, and final sign-off from key stakeholders. |
| SEO / Findability | Targeted rankings for primary industry terms, integration of structured schema markup, rapid crawler indexing, and robust internal linking. |
| Accessibility / Inclusion | Strict adherence to WCAG 2.1 AA standards, comprehensive keyboard navigation, verified screen-reader compatibility, and validated colour contrast ratios. |
§4Quick Reference Guidelines
Ensure your affinity mapping sessions remain productive and unbiased by adhering to these core facilitation principles.
1. Silent Grouping
During the first phase of sorting, enforce absolute silence. Participants should move ideas into clusters without debate, preventing dominant voices from steering the outcome prematurely.
2. Deferred Naming
Never name the groups before sorting begins. The category titles must be the final step, accurately summarising the specific cluster of ideas that formed naturally.
3. Democratic Prioritisation
Once themes are firmly established, utilise dot-voting to quickly identify which categories represent the highest priority or highest risk to the project's overall success.
