Tuckman was Wrong (Assumptions around team formation > performing)


Tuckman's Theory of Group Development was first published by Bruce Tuckman in 1965. In Tuckman's original explanation, groups and teams go through four stages as they become a cohesive, high-performing unit; Forming, Storming, Norming, and Performing. While a commonly accepted model of how teams form, science tells us that Tuckman's Theory is wrong. The stages he defines are not really stages at all, do not happen in a specific sequence, and are not all experienced by all teams. Our top argument for why teams need to be kept stable has been invalidated.
