6. Test & Evaluate



You should be testing your product throughout the making stage of building your product - if your testing highlights an area of weakness or where an alternative is suitable then modify your design and move on. The Stage 3: Develop section of the design cycle is designed to aid in reducing the frequency that modifications need to happen to designs but cannot totally eliminate this from occuring. If this happens to you do not worry about it, just modify your design and make note about why you needed to so that you can refer to this when you write your evaluation of the project.


The evaluation document is a reflection of the whole project from start to finish. Evaluating a project is essential for all designers as it allows them time to reflect on what they have done so that they can learn from the experience and use this knowledge when they design other products in the future.

Your Evaluation needs to include the following:

  1. Photos of your final piece of work (1 on its own and 1 being used if possible),
  2. A written evaluation & reflection (in paragraph format) of your final product.

Here are some prompting questions that you can use to get you started as you write your evaluation of your final product:

  • Brief explanation of what you have designed and made, why it is designed like it is and its purposes.
  • Did you use your time effectively?
  • What have you learned whilst completing your product?
  • What did you find easy?
  • What difficulties have you overcome?
  • What are the strengths and weaknesses of your design?
  • What are the views of others about your product?
  • What would you do differently if you made the same or a similar product again?
  • How will what you have learned help you in the future?
  • What do you think of the overall design? What changes would you make?
  • Are you happy with the materials you chose? Would you make adjustments next time?
  • Did the project take too long?
  • Would it be easy to set up a production line to manufacture your product?
  • Is your solution safe? Could it be made safer?
  • Are the techniques you used to make the product adequate or would you use a different range of manufacturing techniques next time?
  • Is the solution the right size/shape?
  • What are the views of the other people regarding your design?
  • Does it work? What changes are required?
