Testing And Evaluating

Overview

Designing is never a single straight line from brief to product. Good designers are constantly checking their work against what it is supposed to do, finding problems early, and improving as they go. Testing and evaluating is that checking habit made formal: comparing what you have made against the specification, judging how well it meets the needs of the user and the wider world, and being honest about what worked and what did not.

This note covers the 0445 testing and evaluating objectives: why testing and evaluation must run throughout the whole design process and not just at the end; how to evaluate a product against its specification and across its social, ethical and environmental life cycle; how to write balanced concluding comments about successes and limitations; and how to propose sensible further developments. Each idea is grounded in real product examples so you can apply the same thinking to your own coursework.

Objectives

  1. understand the importance of testing and evaluating throughout the design process
  2. evaluate a product with reference to the specification, and its social, ethical and environmental impact throughout its life cycle
  3. make concluding comments about the successes and limitations of the design
  4. identify proposals for further development of a product.

Lesson Note

A common misconception is that evaluation is something you do once, at the very end, by writing a paragraph that says the product turned out well. In reality, testing and evaluating run throughout the design process. You test early ideas with quick models, you test a chosen design against the specification before committing, you test joints and finishes on scrap before using them on the real product, and you test the finished article with real users. Each test feeds a small evaluation, and each evaluation changes what you do next. This is the iterative loop at the heart of design: make, test, evaluate, improve, repeated until the product is right.

This section offers a variety of practice questions designed to reinforce your understanding and help you gauge your grasp of the material.

You will encounter a mix of question types, including multiple-choice questions, short answer questions, and essay questions. Each question is thoughtfully crafted to assess different aspects of your knowledge and critical thinking skills.

Use this evaluation section as an opportunity to reinforce your understanding of the topic and to identify any areas where you may need additional study. Don't be discouraged by any challenges you encounter; instead, view them as opportunities for growth and improvement.

  1. When should testing and evaluating take place in the design process? A. Only at the very end, once the product is finished B. Only before any designing begins C. Throughout the whole process, repeatedly informing improvements D. Only if the product fails to work Answer: C
  2. What is the fairest yardstick for evaluating a finished product? A. The designer's personal taste B. The design specification agreed before designing began C. How attractive the product looks D. How quickly it was made Answer: B
  3. Which of these is part of the 'six Rs' used in environmental evaluation? A. Replace B. Repair C. Resell D. Recolour Answer: B
  4. Why is an all-positive concluding evaluation usually marked down? A. Positive comments are not allowed B. It suggests the student has not tested the product critically or found real limitations C. Conclusions must always be negative D. It takes too long to write Answer: B
  5. A good proposal for further development should be: A. Vague, so it covers many possibilities B. Specific, justified and realistic, linked to a limitation found in testing C. Unrelated to the test results D. A general wish to make the product nicer Answer: B
