Development of Function Analysis System Technique in Value Analysis for Product Improvement

Abstract

This paper presents the development of Function Analysis System Technique (FAST) by directly adding the supporting function for follow-on costs saving in order to assure the implementation of such function in value analysis for product, service or procedure impeovement. This will guarantee the process of adding or maintaining the product value in terms of importance inerease. First cost reduction and follow-on cost saving. Moreover, the performance measurement of each proposal of improvement is introduced so as to facilitate the selection of these proposals for implementation. Crucially, the follow-on cost saving emphasizes on energy conservation responding to the energy crisis of the nation and the world. As an illustration, the case study of room illumination improvement is discussed. The study shows that the use of this developed FAST could lead to the first cost reduction of 49,886 Bahts or 11.5% and power saving of 156,804 Bahts/year or 48% In addition, the value in terms of user’s importance is maintained or inereased.
