Example Sequence of Stages
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) or service.
- Problem solving – conceptualizing and documenting design solutions
- Presentation – presenting design solutions
- Design during production
- Development – continuation and improvement of a designed solution
- Testing – in situ testing a designed solution
- Post-production design feedback for future designs
- Implementation – introducing the designed solution into the environment
- Evaluation and conclusion – summary of process and results, including constructive criticism and suggestions for future improvements
- Redesign – any or all stages in the design process repeated (with corrections made) at any time before, during, or after production.
Each stage has many associated best practices.

Famous quotes containing the words stages and/or sequence:
“Phlebas the Phoenician, a fortnight dead,
Forgot the cry of gulls, and the deep sea swell
And the profit and loss.
A current under sea
Picked his bones in whispers. As he rose and fell
He passed the stages of his age and youth
Entering the whirlpool.”
—T.S. (Thomas Stearns)
“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”
—Walter Benjamin (1892–1940)
