Abstract
In order to create things more effectively when the value associated with achieving things is more
important than mere achievement, understanding ‘why things are neededʼ. Manufacturing often involves many people, and mutual understanding is necessary when there are established values at the outset; whereas, value creation through communication is necessary when clear values have not been established. In this article, the authors will explain i) a methodology to reduce ambiguity in software development, which has been considered a problem that must be resolved in conventional engineering, ii) the characteristics of the manufacturing approach of creating value by attempting to utilize ambiguity, and iii) their attempt to observe and model value-creating communication, in which value is added through the use of ambiguity.
