The Design Process

• The design process is an engineering activity
  that turns a concept into reality.
• The concept is a solution to a specific problem
  or a perceived need.
• The process from concept to solution is not
  random. It is a logical sequence of steps to
  develop the best solution to a specific problem.

The Design Process

• The design process is not a one-way street ending
  in the finished product.
• It is a series of stages and check-points where
  each step in this process can be reviewed and
  analyzed. Modifications or refinements can be
  made to the concept.
