This paper presents a historical overview of the Tuckman model describing the stages of group development. Created by Bruce W. Tuckman in 1965 and revised by Tuckman and Mary Ann Conover Jensen in 1977, the model presents the wellknown stages of forming, storming, norming, performing, and adjourning.

The purpose of this study is to examine if there is a difference between service-sector Lean Six
Sigma (LSS) project teams that progress through Tuckman’s group development model and those that do not in terms of the number of completed projects, the number of projects completed on time, the length of time to complete the projects and the total cost savings and avoidance because of the projects.
