A prototype is a simple experimental model of a proposed solution used to test or validate ideas, design assumptions and other aspects of its conceptualization quickly and cheaply, so that the designer/s involved can make appropriate refinements or possible changes in direction.
Aims of the session: to assess whether the needs of the user were met with the implemented ideas.
Group: prototype can be created by one person or by a larger team. Experts and additional team members can help to check that everything has been considered.
Duration: 30 min.-Many Days
Materials needed: Paper, Post-its, pens. Whatever material it takes to create the prototype.
Step 1: Before prototyping, it is important to know what kinds of insights we want to gain. It is necessary to formulate assumptions to be tested and how the experiment is to be carried out.
Step 2: Interacting with the prototype will become an exciting experience for the user and the test will result in new insights.
Step 3: Determine the level of resolution and what exactly is to be done. Define different prototypes to be built. Often it makes sense to think in alternatives and then opt for one.
Step 4: Choose a variant and outline the experiment, if necessary. Low-resolution prototypes focus on the insights with respect to needs, practicality, and functionality and are mostly used in the divergent phase. High-resolution prototypes concentrate on feasibility and profitability.
Prototyping allows to engage with end users or stakeholders, in ways that reveal deeper insight and more valuable experiences, to inform design decisions going forward.
