Fitness for purpose

Designers will have written a design specification, developed from the design brief and based on the results of completed research. This is where a specific list of criteria is written that a designer can follow as a set of rules. During the iterative design process, this specification should be referenced to and designs evaluated against it to ensure the final solution is the best fit.

Six different design criteria, function, materials, environment, performance, target market and aesthetics all illustrated around a main central label saying ‘Design specification’.

Considerations might include:

  • How does the product fit within the range of sizes specified?
  • Does the product fit the client’s taste?
  • Do the materials and components fit within the specified cost limits?
  • Does the product appeal to the target market?
  • Will the design comply with current safety standards?
  • Will the product have a minimal impact on the environment?
