1. EVOLUTION OF A COMMERCIAL PRODUCT FIVE MAIN STAGES 1.DESIGN BRIEF 2.DESIGN SPECIFICATION 3.GENERATION OF DESIGN IDEAS 4.SYNTHESIS 5.PROTOTYPE

2. DESIGN BRIEF ALWAYS THE STARTING POINT FOR A PROJECT-PRODUCT DISCUSION WHEN A PROBLEM IS IDENTIFIED ie A NEED OR A DESIRE NORMALLY GIVEN TO THE DESIGNER BY THE CLIENT IT IS STATED IN SIMPLE TERMS

3. DESIGN SPECIFICATION ONCE THE DESIGN BRIEF IS CLEAR AND AGREED WITH THE CLIENT. THE DESIGNER WILL CARRY OUT A DETAILED INVESTIGATION OF THE PROBLEM. THIS IS CRUCIAL AND STATES WHAT THE DESIGN HAS TO ACHIEVE, WHAT IT MUST DO.

4. GENERATING IDEAS THE SEARCH BEGINS FOR POSSIBLE SOLUTIONS TO MEET THE SPECIFICATION. INITIAL THOUGHTS ARE SKETCHED AND RECORDED THEY MAY BE EXPLORED FURTHER. A TECHNIQUE TO AID GENERATION OF IDEAS IS BRAINSTORMING MODELING IS ANOTHER METHOD TO ASSIST A SOLUTION

5. SYNTHESIS INITIAL IDEAS ARE FURTHER DEVELOPED INTO MORE FEASIBLE SOLUTIONS AT AN APPROPRIATE POINT GOVERNED BY TIME/FINANCE THE DESIGNER MUST NARROW DOWN IDEAS TOWARDS A SOLUTION THE SOLUTION MUST MEET THE DESIGN SPECIFICATION TRIALS TESTS MODELS TO CHECK OUT IDEAS THIS IS CALLED SYNTHESIS

6. PROTOTYPE THE LAST STAGE BUILD A FULL WORKING MODEL OF THE SOLUTION ATTEMPTS TO BE AS CLOSE AS POSSIBLE TO THE SOLUTION IT IS A ONE OFF IT IS USED FOR FINAL TESTING ie ERGONOMICS AESTHETICS IF THE DESIGNER AND CLIENT ARE SATISFIED THEN A MANUFACTURING BASE IS SET UP TO PRODUCE THE PRODUCT
