Typical stages consistent with the rational model include the following:
Pre-production design
- Design brief or Parti pris – an early (often the beginning) statement of design goals
- Analysis – analysis of current design goals
- Research – investigating similar design solutions in the field or related topics
- Specification – specifying requirements of a design solution for a product (product design specification)[19] or service.
- Problem solving – conceptualizing and documenting design solutions
- Presentation – presenting design solutions
