Wants Chain Analysis (tool for analysing and designing social systems considering various needs of humans)

Abstract

In the present paper, WCA (Wants Chain Analysis) is proposed by extending CVCA (Customer Value Chain Analysis). CVCA is a method for visualizing relationship among stakeholders for analyzing existing social systems and designing new social systems. WCA is a method for visualizing wants and needs of stakeholders in CVCA utilizing Maslow's hierarchy of needs. In WCA it is shown that people's wants or needs are finally realized through the looped and linear chain of relationship among stakeholders. With various examples, effectiveness of WCA is shown by describing that characteristics of business/social systems structure can be clearly visualized using WCA. It is described that WCA is useful for analyzing social systems. "Think of others" should be more and more important for humans' satisfaction and happiness in the near future. WCA can be a tool for clarifying what is for others. © 2012 The Japan Society of Mechanical Engineers.
