Evaluate and refine processes

I can write an evaluation and identify further modifications to the design and batch process.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Designers collaborate to evaluate designs.
  2. Designers modify products after evaluating.
  3. Evaluations help to discover if the final design outcome has addressed the original design objectives.
  4. Design specifications and requirements can be used to support writing an evaluation.

Keywords

  • Evaluation - checking how good something is and how to make it better

  • Design outcome - a final product or solution

  • Modifications - making changes or adjustments to improve or alter a design

Common misconception

Once a final product is complete, no further improvements are needed.

Designers constantly seek to improve and develop their designs and products, no product is ever perfect.
