4.4.22 Prototyping test
Description: Prototyping test is a low cost and quick process in which product or service with limited functionality and interaction is tested with real end-users. Interactive prototype product or service must exist so real end-users or experts can experience it. Prototype 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 as real kind of user experience as possible, but at a lower cost. Different methods such as interviews, surveys and observations can be used.
R&D service categories: Testing and validation
Key characteristics in living lab context:
- From rapid prototyping to the MVP
- IT solutions/Physical and cognitive exercises
Objectives:
- 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 mockups, scaled down prototypes, visual dummies close to final (visual UI), video recording, usability questionnaires, eye tracking
