4. Evaluate - (ii) Critically evaluate the success of the solution against the design specification

At the end of year 5 you should be able to:

• carry out a wide range of effective tests to generate qualitative and quantitative data
• explain the accuracy of the data gathered throughout testing
• present the analysis of the data in a clear and concise way
• evaluate the success of the solution against the requirements of the design specification
• explain weakenesses and limitations of the solution based on the analysis of data collected throughout objective and subjective testing against the requirements of the design specification

---

When critically evaluating the success of a solution, you must objectively judge the solution against the specifications. This objective evaluation comes from analysing the data gathered by carrying out the tests designed.

You must analyse this data and make conclusions that identify strengths and weaknesses of the solution, along with opportunities for further development.

Test against design specifications example (could also be a table:

• Test 1
  
  • Specifications 
    • Must have at least 3 sections for putting different types of writing utensils
      
  • Testing method - Yes/No  
    • 5/5
  • Evidence from tests - How is it met?
    • There are three sections for putting different types of writing utensils: one big section and two small sections
      
• Test 2
