Yes. Annex’s published examples describe prototype testing informing and validating an approach. Research and usability testing can help a team check whether its assumptions match how people understand and use a service, and the findings may influence design decisions. What changes as a result depends on what testing reveals and on the project’s constraints. Annex describes an iterative process of design, thorough testing and improvement, rather than treating a prototype as a final decision.
Public Q&A
If we have a prototype already, can user testing still change what we build?
Useful next steps
Use this answer as a practical starting point. Current scope, specifications, compatibility, availability, pricing, timing and next steps should be confirmed directly with Annex where they affect a decision.
