Prototyping test

Description: Prototyping test is a low cost and quick process in which a product or service with limited functionality and interaction is tested with real end-users. An interactive prototype product or service must be available so real end-users or experts can experience it. This prototype test can be, for instance, an interactive mock-up of a web service, which interface looks like a real thing. One can navigate through different screens and see simulated content. Also, the service prototype can consist of role-playing exercise to simulate service encounters. The main aim is to collect feedback on a 'close to real' user experience as possible, but at a lower cost. Different methods such as interviews, surveys and observations can be used.

R&D service category-ies: Testing and validation

Key characteristics in Living Lab context:

  • From rapid prototyping to the MVP
  • IT solutions/Physical and cognitive exercises


  • Similar to proof-of-concept but testing higher fidelity solution,
  • Identify improvement suggestions and usability test,
  • Provides development recommendations based on user/patient/customer experience and needs,
  • Identify key measures to investigate in follow-up tests

Methods: Survey, observation, demo-session, interview, Wizard of Oz, usability tests, role playing

Tools: Paper prototype, wireframes, interactive mock-ups, scaled down prototypes, visual dummies close to final (visual UI), video recording, usability questionnaires, eye tracking
