Design Criteria


To evaluate any design or the process that lead to the completion of that design, a series of evaluation criteria are required. These evaluation criteria allow the designer to understand how well the requirements of the design brief were met or surpassed. They also allow the designer to fine tune their professional practice and design skills. Simply put, evaluation criteria are the questions the designer asks to ensure they are meeting the requirements of quality management (AS/NZ ISO 9000), meeting Occupational Health and Safety management systems (AS/NZS ISO 4801) and continual improvement. Evaluation criteria are questions based on the brief's product design specifications. They should be written as open ended questions that call for detailed qualitative or quantitative answers during both the design process and on conclusion of the design process. This allows the designer to use the criteria to judge the effectiveness of each concept as it conceived.

Examples of Evaluation Criteria

Design Concepts

  • Does the seating system allow the user to ergonomically use the working surface?
  • Does the semiotics of the product visually communicate its purpose?
  • Can the storage system be installed into the intended environment?

Design Process

  • Was the working surface designed to carry the weight of tools and working force applied by the user?
  • What did the testing data indicate about the material's ability to support required weight?
  • What difficulties were encountered in the design of the storage system? How were these overcome?
