Abstract
Conditions and methods for idea generation were gathered from the questionnaire survey for development managers. Idea is likely generated when an incompleteness is allowed, team members are self-motivated, and tasks are urgent. The importance of these conditions varies according to the stage of development. There are 80 methods to fulfill the conditions in a team. They are applicable in food, software, and home electron-ics developments, and in the workshops in educational institutions. We expect to apply the methods in idea generation stage of 3S model and Boost-Gate method®.
