Research Topic 196 / 200
Research samples lack diversity
Testing includes only people familiar with the product, overlooking first-time users and maintenance teams.
Three-step solution method
- Create a participant coverage matrix based on roles, experience and usage environments.
- Design comparable tasks and recording methods for different participant groups.
- Report shared issues and group differences separately to avoid conclusions that obscure variation.
Key Deliverables
- Sample Coverage Matrix
- Task Plan
- Research Findings by Group
Verification Approach
Check that key roles are represented and that group differences are supported by evidence.
