Criterion D: Evaluating

Your task will be to design detailed and relevant testing methods, which generate data, to measure the success of the solution. 
Critically evaluate the success of the solution against the design specification. 
Explain how the solution could be improved in future and 

Explain the impact of the solution on the client/target audience.

Strand (i)

Design detailed and relevant testing methods that generate data to measure the success of the solution.

• Design a wide range of effective tests to evaluate the solution against the requirements of the design specification (including expert appraisal, user trials, field testing and user observation)

Strand (ii)

  Critically evaluate the success of the solution against the design specification.

This will be achieved by;

• 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 weaknesses and limitations of the solution based on the analysis of data collected throughout objective and subjective testing against the requirements of the design specification.

Strand (iii)

 Explain how the solution could be improved

• Explain, in detail, how the identified weaknesses and limitations of the solution could be improved in the product.

Strand (iv)

Explain the impact of the solution on the client/target audience
