      Lesson details

      Learning outcome

      I can gather and analyse feedback to identify strengths and weaknesses in my design.

      Key learning points

      1. Prototypes testing reveals strengths and weaknesses in a design.
      2. Feedback collection and analysis informs improvements and design decisions.

      Keywords

      • Testing - trying out a design to check its performance

      • Feedback - information from primary users or stakeholders about how well something works

      • Design requirements - something which is needed or wanted to make a product successful

      • Design decisions - a deliberate choice to meet a requirement or solve a problem

      Common misconception

      Testing is only to prove that a design works.

      Testing is equally about finding flaws and learning what doesn’t work; failures provide insight.

      Teacher tip

      Model how to give constructive feedback (specific, linked to criteria, not just “good/bad”).
