A comparison has been made between TRIZ matrix with Value Study matrices and discussed to achieve product optimization. Finally, results obtained are discussed.

INTRODUCTION A New Product Development (NPD) phase is a stage-gate product development process used by many companies in order to encourage rapid product development and to cull out the least promising projects before large sums of money are committed. The application of NPD is based from the engineering design process which consists of 7 main phases; conceptual design, embodiment design, detail design, planning for manufacture, planning for distribution, planning for use and planning for retirement [1]. Figure 1 below shows the flow summary of the 7 phases. Fig. 1. Summary of the Engineering Design Process for NPD Previous study shows integration has been made between NPD and Value Study; Value Analysis (VA) and Value Engineering (VE) [2]. VAVE has proven its ability to verify the worth of a particular product and process through the application on series of tools governs by the Job Plan. However, it is found that a new integration within these methodologies with the one been applied within the Theory of Inventive Problem Solving (TRIZ) may further enhance the verification process and lower the design risk. This would then give the opportunity to improve the design value without compromising with the harmful may present. II. JOB PLAN Job Plan consist of three main phases; Pre-workshop, Workshop and Post-Workshop. While Pre-workshop phase assign to prepare for the foundation of the studies and Post- workshop responsible for the follow up action plan, the Workshop phase involve six other sub-phases; information gathering phase, function and analysis phase, creative phase, evaluation phase, development phase and presentation phase [3]. A new integration is found within the Workshop phase of Job Plan where new tool can be introduced from TRIZ;
