Phases and Interactions of the Design Process

• What is the design process? 
• How does it begin? 
• Does the engineer simply sit down at a desk with a blank sheet of paper and jot down some ideas? 
• What happens next? What factors influence or control the decisions that have to be made? 
• Finally, how does the design process end? 

The phases in design, acknowledging the many feedbacks and iterations

The complete design process

• The process begins with an identification of a need and a decision to do something about it 
• After many iterations, the process ends with the presentation of the plans for satisfying the need 
• Depending on the nature of the design task, several design phases may be repeated throughout the life of the product, from inception to termination 
• Identification of need 
• The definition of problem 
• The synthesis (Concept design) 
• Analysis and optimization 
• Evaluation 
• Presentation
