Team stages

Team stages is a concept, first introduced by Bruce Wayne Tuckman, a psychologist, in 1965. The theory was given an official name, "Tuckman's Stages". Researching processes and dynamics inside teams is the groundwork for "Tuckman's Stages". Earlier in his findings, Tuckman determined four stages: Forming, Storming, Norming, Performing. But several years later, fifth stage, Adjourning, was added to the theory.
