D: Evaluating

Outline simple, relevant testing methods, which generate data, to measure the success of the solution

Design performance tests for your pen. (The performance of a solution is tested under the conditions in which it would normally be used.)

Outline the success of the solution against the design specification

Using the success criteria from B: Developing Ideas, complete the following table.

Outline how the solution could be improved

Take into consideration the results of your performance tests and the above table. How could you improve your pen?

Write a paragraph to describe how you could improve your pen

and

Take a scan or photo of your pen and annotate the image showing how you could improve the design. or carefully complete a design improvement sketch.

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

Refer back to the very start of this project. What is the possible impact of having a custom made, ergonomic pen a made just for you?

Are you likely to keep it for a long time? Why?

Is it easier to write or draw with this pen?
