Combining multiple theories and the development models of Tuckman and Gersick, Morgan, Salas and Glickman (1994) created the Team Evolution and Maturation (TEAM) model to describe a series of nine developmental stages through which newly formed, task-oriented teams are hypothesized to evolve.
The IPO model of teams is a systems theory, as it rests on the assumption that a team is more than one-to-one relationships between variables, and more than the sum of its members. It suggests that there are interactions and feedback between many contributing factors. [ 2 ]

He suggested that these inevitable phases were ...
The equilibrium model is a progressive model as it explains group maturity and performance over a given period of time. [6] Bales proposed the model as a means to study the manifestation and incidence of task-oriented and socio-emotional behaviours. [7] There are three main stages of group development within the equilibrium model. [6]

John Adair developed a model of Action-Centred Leadership comprising 3 interlocking balls in a venn diagram arrangement, labelled Task, Team and Individual on the premise that:
In reviewing the older leadership theories, Scouller highlighted certain limitations in relation to the development of a leader's skill and effectiveness: [3] Trait theory: As Stogdill (1948) [4] and Buchanan & Huczynski (1997) had previously pointed out, this approach has failed to develop a universally agreed list of leadership qualities and "successful leaders seem to defy classification ...

As early as World War II (1939-1945), Lewin experimented with a collaborative change-process (involving himself as a consultant and a client group) based on a three-step process of planning, taking action, and measuring results. This was the ...
