Formation of groups
SAT6B-Social Psychology II 4
Psychologist Bruce Tuckman first came up with the memorable
phrase "forming, storming, norming, and performing" in his 1965
article, "Developmental Sequence in Small Groups."
He used it to describe the path that most teams follow on their way
to high performance. Later, he added a fifth stage, "adjourning"
(which is sometimes known as "mourning").
