1965年に主張された「組織の形成過程には4つのフェーズがある」という意見。
4つのフェーズが順番に来るのではない、という修正がDAUモデル
The development of small, short duration technical teams in particular and technical teams in
general appears to follow a variant of the Tuckman model (F<S<N<P). This model, which will
be called the DAU model, has three discrete stages (F<N<P) and one continuous
Brainstorming stage that takes place over the entire duration of the group. The brainstorming
activity can be described as group members challenging each other’s ideas and approaches in a
cooperative way with the intention of producing a better product or improving the group’s
process (efficiency and productivity).
