Comparing team development models and choosing the right one

A team that meets its deadlines can still end up working at cross-purposes. Decisions are postponed, conflicts are taken into one-to-one discussions, and new colleagues find it difficult to settle in. Anyone wishing to compare team development models should therefore not look for the most appealing theory, but for a robust answer to a specific question: What is currently preventing this team from working together effectively?

Models provide guidance. They reveal patterns, put into words dynamics that are difficult to grasp, and help ensure that measures are not chosen based on gut feeling. However, they only have an impact if they are suited to the team’s starting point, its remit and its day-to-day work. No model can replace a close examination of what is actually happening between people, roles and tasks.

Why comparing models is more than just theory

Team development is often equated with a shared experience. A well-designed format can strengthen trust and energy. However, when roles are unclear, a conflict is smouldering or new silos are forming following a reorganisation, a positive experience alone is rarely enough. In such cases, the team needs a structured development process.

The well-known models address different aspects. Some explain how groups typically grow. Others examine the prerequisites for performance. Still others focus on trust, conflict or leadership. Anyone who treats them all the same risks implementing a measure that seems appealing but fails to address the actual bottleneck.

The crucial shift in perspective is this: the model is not chosen simply because it is well-known. It is selected as a working tool because it enables the relevant team issue to be addressed precisely.

Comparing team development models: four approaches in use

Tuckman: Understanding development as phases

Bruce Tuckman’s phased model describes the development of teams through the stages of Forming, Storming, Norming and Performing. Later, Adjourning was added as a final phase. Its strength lies in normalising tensions: friction is not automatically a sign of a failed team, but can be part of the process of clarification.

The model is particularly helpful for new teams, following mergers, at the start of a project, or when the team’s composition and responsibilities have changed significantly. It makes it easier for managers to recognise why a team still needs a great deal of guidance, or why rules and decision-making processes need to be renegotiated.

The limitation: real-life teams do not progress neatly from one phase to the next. They may find themselves back in a state of uncertainty when starting a new project, or old conflicts may resurface following staff changes. Tuckman is therefore a useful framework for orientation, but not a diagnosis of the actual cause of the conflict.

GRPI: Systematically assessing performance prerequisites

The GRPI model considers four areas: Goals, Roles, Processes and Interpersonal Relationships. Put simply, these are objectives, roles, processes and relationships. The logic is clear: performance does not stem solely from good relationships. Teams also require a shared mission, clear responsibilities and effective workflows.

GRPI is particularly well-suited when collaboration is generally respectful, but results remain too slow, inconsistent or unclear. Typical questions include: Does everyone understand the same objective? Who decides what? How are interfaces managed? Where is information getting lost?

The major advantage lies in its practical relevance. Agreements can be derived directly from the analysis – for example, regarding meeting frequencies, escalation procedures or accountability structures. At the same time, the model should not be applied mechanically. A supposed process issue may actually conceal a power struggle. In such cases, more than just a new agenda is required.

Lencioni: Addressing Dysfunctions Openly

Patrick Lencioni’s model of the five dysfunctions focuses on trust, conflict resolution, commitment, accountability and results orientation. It is particularly effective when a team appears polite but avoids critical issues. Where there is no open discussion, decisions are often made without genuine commitment, and a culture of turning a blind eye develops.

This approach provides leaders and teams with a clear framework for understanding sensitive patterns. Rather than accusing individuals of a lack of motivation, the team can examine whether uncertainties are being left unaddressed, whether conflicts are being resolved too quickly, or whether there is a lack of mutual accountability.

His focus on behaviour and relationships is, at the same time, its limitation. Structural problems such as unrealistic targets, unclear mandates or competing management approaches are not automatically resolved. Lencioni’s approach is therefore most effective when the focus is on collaboration within the core team, and should be supplemented when dealing with complex organisational problems.

Systemic team diagnosis: recognising patterns within their context

Systemic approaches do not view a team in isolation. They examine interactions with leadership, other departments, customers, decision-making processes and the wider context. A conflict between sales and operations, for example, may have less to do with personal chemistry than with conflicting key performance indicators or unclear handover procedures.

This perspective is useful for cross-functional teams, change processes, recurring interface issues and conflicts that remain unresolved despite workshops. It prevents the team from being held solely responsible for difficulties that arise within the system.

This requires a clear mandate and professional facilitation. Not every external dependency can be changed in a team workshop. Effective team development therefore distinguishes between what the team can agree upon itself and what leadership or the organisation must decide.

Which model suits which team situation?

The selection process does not begin with an overview of models, but with a clear definition of the brief. Four questions help to narrow down the development requirements:

• Is the main focus on finding one’s bearings within a new or changed team structure?
• Is there a lack of clarity regarding objectives, roles, decision-making or work processes?
• Are tensions, mistakes or critical feedback being avoided?
• Could the cause lie outside the team, for example at interfaces or due to conflicting expectations?

Tuckman provides a helpful framework for orientation and team building. When it comes to performance and structural issues, GRPI leads more quickly to concrete working agreements. Where there is a lack of openness and commitment, Lencioni provides insight into behavioural patterns. If the team is stuck in a complex environment, a systemic diagnosis is usually the more appropriate starting point.

In practice, models are often combined. A newly formed management team can use Tuckman to map out its development phase, clarify responsibilities using GRPI, and then work on conflict management skills. The order in which this is done is crucial: attempting to build trust first, even though objectives and mandates are contradictory, leads to frustration. Merely defining processes, whilst conflicts are off-limits, results in agreements that have no real impact.

From model to measurable development

A model only becomes valuable when it is translated into observable changes. After following a development framework, a team should be able to say what it will do differently in future: how decisions are made, when conflicts are addressed, who bears which responsibilities, and how progress can be recognised.

A three-step approach is recommended for this. First, the current situation is assessed, for example through structured interviews, a team check or a brief evaluation of key success factors. The team then addresses the prioritised issues in a facilitated format. Finally, binding implementation agreements are drawn up and a follow-up assessment is carried out after a few weeks.

In this context, measurability does not mean reducing team dynamics to a single metric. It creates a common basis for determining whether clarity, trust, communication or accountability have actually improved. Measurement becomes particularly valuable when a team is not merely given a status update, but can identify changes between the initial situation and the follow-up assessment.

BITOU combines this reflection with experience-based and work-related development programmes. In this way, a sense of ‘we’ does not arise in isolation from everyday life, but rather as the foundation for concrete collaboration, which leads to tangible and demonstrable improvements within the team.

Leadership determines the transfer of learning

A team may reach good agreements in a workshop and yet still fall back into old patterns after two weeks. Often, this is not due to a lack of will, but to the demands of everyday life: time pressure, new priorities and unresolved decisions quickly overshadow the impetus for development.

Managers ensure this transfer takes place by keeping the agreed behaviours visible. This may involve reviewing decision-making rules at regular meetings, addressing tensions at an early stage, or not reclaiming responsibilities at the first sign of difficulty. The team also bears responsibility: members must be able to hold one another to these agreements in day-to-day work.

The right framework provides clarity. Lasting change occurs when a team has the courage to examine its actual patterns and develops sufficient commitment to change them together.
