Rapid prototypes
Choose solutions
Complexity Rapid prototypes can be used to test and communicate solution ideas. If this concerns more comprehensive solutions, it will often only be selected parts of a solution that can be tested in a prototype.
Prototypes are an unfinished and physical version of an idea for new or changed workplace layout and design, workflow, distribution of tasks, technical aids, user interfaces, and the like.
Prototypes can be produced in many different ways and using different materials:
• Diagrams on a piece of paper or a whiteboard, for example a physical model, sequence model, or a flow model. • Spatial models built in LEGO or cardboard. • Draw a new layout on an architectural drawing of the workplace layout. • Draw a new design by drawing on a photo of a machine, equipment, or technical aid. • Build a mock-up either in a scale ratio or in full scale. • Use brightly coloured adhesive tape on the floor to indicate new rooms, spaces, or partitions. • Come up with more examples yourself ...
Some prototypes can be supplemented by scenario-based simulation.
Steps 1. Start by finding out whether a solution idea or parts thereof can be expressed in a prototype. 2. Find out how the prototype can be used to test and assess a solution idea. Can the participants play a scenario? Can the participants move about physically in the prototype, as is, for

example, the case in a full-scale mock-up or using adhesive tape on the floor. If the prototype consists of work models drawn on a piece of paper, the participants can assess solution ideas by comparing models of the current work situation with models of a possible future work situation, for example a changed workflow or a change in the distribution of tasks between the employees. 3. Make the prototype. 4. Conduct a test or an assessment of one or more solution ideas – using a scenario, physical movement in mock-up, or a comparison of models. 5. Hold a debriefing for each completed test: What worked well? What worked less well? What needs to be redone? 6. If the prototype can be changed on site, you can do so and then conduct a new test. 7. The results can be used to choose from several solution ideas and as input for creating one or more solution concepts.
