What app prototypes can tell you before development

A prototype turns an idea into screens people can explore. It can make a conversation much more specific, but it answers different questions from a working product. Knowing that distinction helps a team make better use of it.

Test the journey

Faffin’s design work includes mobile consumer and business experiences. A prototype can help examine whether someone understands an offer, finds the next step and recognises the purpose of a screen. It can also reveal where a journey needs an explanation that the design does not yet provide.

Record the questions it cannot answer

A clickable screen does not establish database performance, payment settlement, permissions or production reliability. Those need implementation and separate testing. Write down which interactions are demonstrated, which are simulated and which still need a technical decision.

Use feedback to choose the next build

Look for repeated confusion and missing steps rather than collecting only visual preferences. A focused prototype review should produce decisions: change a label, add a state, simplify a flow or investigate a dependency. That gives development a clearer starting point.

A LITTLE THINKING. A USEFUL NEXT STEP.

Put it into practice

  • Define the question for each test
  • Distinguish simulated and working features
  • Translate feedback into specific changes
