The process begins with an initial statement of a need, and the first design activity is analysis of the problem. French suggests that the analysis of the problem is a small but important part of the overall process. The output is a statement of the problem, and this can have three elements:
• a statement of the design problem proper
• limitations placed upon the solution, e.g. codes of practice, statutory requirements, customers' standards, date of completion, etc.
• the criterion of excellence to be worked to.
