Abstract
In recent years products and services, and many business model development sites, there are many companies that hold short-term workshops and create ideas to propose ideas in line with changes in the environment. While short-term workshops have the advantage of being able to quickly bring up ideas, they are not always sufficiently reviewed, and have the problem that they are not unique and there are many similar ideas. According to the previous report of the authors, it is proposed to organize ideas by performing reflection on ideas using ”Inverted Triangle”, but it is assumed to be done after ideas have been fully reviewed. The results of short-term workshops are not considered. In this research, in order to reinterpret the ”focused point” of the idea created in the short-term workshop and improve the description about ”uniqueness”, a proposal sheet for preparing the idea inside the idea was proposed and its effect was confirmed.
