A design process includes a series of steps followed by designers. Depending on the product or service, some of these stages may not be necessary.

Typical stages of the design process include:

• Pre-production design
• Design brief - a statement of the customer's design goals
• Specification - specifying requirements of the design
• Problem solving - conceptualizing and documenting design solutions
• Presentation - presenting design solutions by creating a computerized 3D model
• Design during production
• Development - continuation and improvement of a computer designed solution
• Testing - producing a rapid prototype of  the design for fit and function
• Post-production design feedback for future designs
• Implementation - evaluating the 3d model in a real world situation ( Does it work? Is it strong enough to last?)
• Evaluation and conclusion - summary of process and results, including 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

Redesign: Something that is redesigned requires a different process than something that is designed for the first time. A redesign  includes an extensive evaluation of the existing design.   Those findings will drive the redesign process to include all necessary improvements to the original.
