<P> The forming--storming--norming--performing model of group development was first proposed by Bruce Tuckman in 1965, who said that these phases are all necessary and inevitable in order for the team to grow, face up to challenges, tackle problems, find solutions, plan work, and deliver results . </P> <P> The team meets and learns about the opportunities and challenges, and then agrees on goals and begins to tackle the tasks . Team members tend to behave quite independently . They may be motivated but are usually relatively uninformed of the issues and objectives of the team . Team members are usually on their best behavior but very focused on themselves . Mature team members begin to model appropriate behavior even at this early phase . The meeting environment also plays an important role to model the initial behaviors of each individual . The major task functions also concern orientation . Members attempt to become oriented to the tasks as well as to one another . Discussion centers around defining the scope of the task, how to approach it, and similar concerns . To grow from this stage to the next, each member must relinquish the comfort of non-threatening topics and risk the possibility of conflict . </P>
