Tuckman's group-development model was first proposed by Bruce Tuckman in 1965 with four stages, and later expanded with Mary Ann Jensen in 1977 to add a fifth. It remains one of the most widely used models for understanding how groups mature from a collection of individuals into a high-performing team, and is particularly valuable to managers who form project teams, cross-functional sourcing teams, or supplier-development working groups.
Forming is the initial stage when group members come together. Behaviour is typically polite, tentative, and dependent on the leader for direction. People focus on understanding the task, learning each other's names and roles, and avoiding controversy. Productivity is low; uncertainty is high. The manager's role is to provide clear objectives, define roles, and create psychological safety.
Storming follows once members feel safe enough to express disagreement. Personalities emerge, conflict surfaces over priorities, working methods, and informal hierarchy, and some members may challenge the leader. This is the most uncomfortable stage but also a necessary one — without storming, real norms cannot form. The manager must facilitate constructive disagreement, mediate where conflict becomes destructive, and resist the temptation to suppress all dissent.
Norming emerges as the group settles its disputes and develops shared expectations about behaviour, communication, and decision-making. Trust grows, members begin to identify as a team rather than as individuals, and there is a collective sense of 'how we do things'. Productivity rises noticeably. The manager's task shifts from refereeing to coaching — reinforcing the agreed norms and removing remaining obstacles.
Performing is the stage where the team operates with high autonomy and high effectiveness. Members understand each other's strengths, communication is fluid, and the team can take on complex problems with confidence. The manager can step back into a more strategic, supportive role — providing resources, removing organisational barriers, and championing the team externally.
Adjourning (Tuckman & Jensen, 1977) is the final stage when the team disbands, either because the project is complete or because reorganisation breaks it up. There can be a sense of loss, especially in long-standing teams; a thoughtful manager will mark the ending — celebrating achievements, capturing lessons learned, and supporting members into their next assignments.
Belbin's team-roles framework complements Tuckman by addressing not the time dimension of team development but the composition dimension. Meredith Belbin, working at Henley Management College in the 1970s and 1980s, identified nine preferred behavioural roles individuals tend to play in teams: Plant (creative ideas-generator), Resource Investigator, Co-ordinator, Shaper (driving force), Monitor-Evaluator, Teamworker, Implementer, Completer-Finisher, and Specialist.
Applying Belbin during storming. The storming stage is where Belbin's diagnostic value is highest. Conflict often arises because people misread each other's behaviour: a Shaper's drive can be experienced as aggression; a Plant's stream of ideas can frustrate an Implementer who wants to get on with the existing plan; a Monitor-Evaluator's measured scepticism can be heard as obstruction. By having team members complete a Belbin self-perception inventory and sharing the results openly, the manager can reframe conflict as a difference in role-preference rather than personal failing. A Shaper can be told 'your drive is exactly what we need at the start of a sourcing project, but please give the Monitor-Evaluator time to surface risks before pushing for a decision'. This shifts the conversation from blame to design.
Applying Belbin during norming. As the team begins to form shared norms, the manager can use Belbin to ensure those norms accommodate the team's actual composition rather than an idealised one. If the team lacks a Completer-Finisher, the agreed norm should explicitly assign someone to drive deadlines and check details — otherwise, a brilliant Plant-heavy team will generate ideas but never deliver. If the team is heavy on Teamworkers but light on Shapers, the manager may need to lead more directively at the start of each task. The norming-stage agreement on 'how we work' becomes more realistic when grounded in role data.
Both models have limitations. Tuckman's stages are not always strictly linear — established teams can be thrown back into storming by the arrival of a new member or a major change in scope. Belbin's nine roles emerged from observation, not controlled experiment, and the self-perception inventory is open to social-desirability bias. Even so, used together, the two frameworks give a procurement manager a powerful pair of lenses: one for diagnosing where the team is in its development, the other for understanding who is in it. Used honestly, they accelerate the journey from forming to performing.
