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. 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 system structure can be clearly visualized using WCA. It is described that WCA is useful when it is used for analyzing existing systems as well as creating new systems. It is also shown that “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.
