 Using Tuckman's stages of group development as a basis, a HPT moves through the stages of forming, storming, norming and performing, as with other teams.However, the HPT uses the storming and norming phase effectively to define who they are and what their overall goal is, and how to interact together and resolve conflicts.Therefore, when the HPT reaches the performing phase, they have highly effective behaviours that allow them to overachieve in comparison to regular teams.
