Team Principle of Development

Team development stages

A team is not made by its lineup but by time.

The dots find one another loosely, rub against each other, fall into order and finally rotate as one. Meanwhile, a timeline fills up at the bottom.
In short

A team is not made by its lineup but by time.

A lineup only gives you a list of names. It does not yet give you a team. A team is a well-practiced fabric of roles, rules and trust – and that has to grow first.

In depth

The team principle in detail

Four steps through the principle: understand, check, connect, apply. Open any topic to read more.

The explanationThe reason is simple. At the start, no one knows exactly who can do what, who decides what and how people deal with one another here.
  • The reason is simple.
  • At the start, no one knows exactly who can do what, who decides what and how people deal with one another here.
  • No job description settles these questions.
  • They are settled by working together: through tasks, through mistakes, often through friction as well.
  • “Time” therefore means shared experience, not just months on the calendar.
Read closelyWhat the principle says – and what it doesn’t
At its core

A good lineup is the beginning, not the result. What makes a team grows only through working together.

Strictly speaking
Time is necessary, but it is not enough. Some groups stay stuck in conflict. If you just wait, you will not automatically end up with a mature team.
There is no fixed sequence of phases that applies to all teams. Teams often mature in leaps rather than steadily. Conflict is normal in the early phases, but it is not a mandatory stage.
The principle applies to groups that work together over a longer period. Highly trained professionals with fixed roles, such as flight crews or surgical teams, can start working immediately because they learned their roles beforehand.
The signs3 signs that the principle is at work · 3 that it is missing
The principle is at work
  • The leader expects a start-up period and plans for it.
  • Roles and rules are clarified explicitly.
  • Early friction is worked through rather than complained about.
The principle is missing
  • Full performance is expected from day one.
  • At the first sign of trouble, people are swapped out.
  • The team is reshuffled so often that it never gets past the beginning.

Moderate – that groups change measurably over time is established; a fixed sequence of phases that is the same for all teams is not.

  1. 1965
    Review / Theory
    Bruce W. Tuckman

    Analysis of 50 articles on the developmental stages of groups. From this came the model forming – storming – norming – performing.

  2. 1977
    Review
    Bruce W. Tuckman & Mary Ann C. Jensen

    Review of 22 studies from ten years: only one tested Tuckman’s hypothesis directly. The authors add a fifth stage (adjourning) and call for more empirical work.

  3. 1988
    Primary study / Critique
    Connie J. G. Gersick

    Eight natural project teams over their entire life span: an alternation of inertia and upheaval instead of fixed phases. The trigger is awareness of time and deadlines, not the amount of work completed.

  4. 2003
    Primary study
    Susan A. Wheelan, Barbara Davidson & Felice Tilin

    26 work groups (conversation analysis) and 88 groups (survey): longer-standing groups show fewer expressions of dependency and conflict and more work on the task.

  5. 2006
    Review
    Steve W. J. Kozlowski & Daniel R. Ilgen

    Major overview of team effectiveness: a team’s cognition, motivation and behavior emerge over time from working together and can be fostered through training, leadership and design.

  6. 2010
    Review / Critique
    Denise A. Bonebright

    History of the Tuckman model: popular first among practitioners, then widely adopted in academia – partly for lack of applicable research.

Where the research reaches its limits
  • Tuckman’s phases come from a literature review, mostly of therapy, training and laboratory groups, and have hardly been tested directly.
  • The finding that older groups work more maturely rests mainly on cross-sectional comparisons.
  • It does not follow that every group will mature if you just wait.
Read more: what the research shows

The field is called group development: it studies how groups change over the course of their existence. The best-known framework is Bruce W. Tuckman’s phase model, with the stages forming, storming, norming and performing. Susan A. Wheelan, Barbara Davidson and Felice Tilin found that longer-standing work groups show, on average, less dependency and conflict and do more work on the task. Connie J. G. Gersick, by contrast, observed in project teams not a steady progression through phases but an alternation of inertia and upheaval, triggered by awareness of time and deadlines. In their overview, Steve W. J. Kozlowski and Daniel R. Ilgen describe how a team’s thinking, motivation and behavior emerge over time from working together.

The related team principles11 Attunement · 12 Reliability · 14 Conflict · 22 Investment

The principle is the time axis for “Attunement”, “Reliability” and “Conflict” and fits with “Investment”.

“Leadership” has to deliver something different in each phase.

It stands in tension with “Bench” and “Diversity”, because every change in the lineup sets the team back.

The action steps5 steps: Plan a start-up period for every new team, and make that clear to your own superiors as well.
  1. Plan a start-up period for every new team, and make that clear to your own superiors as well. Do not measure a young team against a well-established one.
  2. Clarify early what would otherwise stay open for a long time: who has which role? Who decides what? How do we treat one another?
  3. Use deadlines and the midpoint of a project for a deliberate pause: what is working, what will we change? Teams often change course at such moments.
  4. Do not see early conflicts as failure. But step in when camps form and the dispute becomes entrenched.
  5. Change the lineup with care. Every change sets the team back a little.
The questions for your team3 questions for your team conversation: Where are we as a team right now – still sorting ourselves out, or already working on the task itself?
  1. Where are we as a team right now – still sorting ourselves out, or already working on the task itself?
  2. Which question about roles, rules or decisions is still unresolved in our team?
  3. What did the last change in our lineup cost us, and what did we learn from it?

Take time for one question at your next team meeting. Talk about it openly and note down what you take away from it.

The picture to rememberThe dots find one another loosely, rub against each other, fall into order and finally rotate as one.

The Team Principle of Development in practice

From every sphere of society.

Sports & Arts

The Beatles in Hamburg and the Team Principle of Development

When the Beatles arrive in Hamburg in August 1960, their drummer has been with them for only a few days. They play four sets a night, later 92 nights in a row. Two years on, five young musicians have become a band – with a different lineup from the one they started with. A team is not made by its lineup but by time.

The Chicago Bulls and the Team Principle of Development

In 1984 the Chicago Bulls sign Michael Jordan. They win their first title in 1991 – in his seventh season and after three straight playoff defeats against Detroit. In the years between, the roster, the system and trust all develop. A team is not made by its lineup but by time.

Biosphere 2 and the Team Principle of Development

Eight people live sealed inside a glass structure in Arizona for two years (1991–1993). After about six months, the group splits into two camps. This is a counterexample: it shows the Team Principle of Development through its failure. A team is not made by its lineup but by time – but time alone is not enough.

Movie – Marvel’s The Avengers (2012)

In “Marvel’s The Avengers,” Nick Fury brings together six exceptional talents – and gets quarrels instead of cooperation at first. Only after a shared loss do they fight as one. The film shows, in condensed form, that a team is not made by its lineup but by time.

FAQ

Questions about the Team Principle of Development

What does the Team Principle of Development say?

A team is not made by its lineup but by time. A lineup only gives you a list of names. It does not yet give you a team. A team is a well-practiced fabric of roles, rules and trust – and that has to grow first.

How can I tell whether my team follows the Team Principle of Development?

The leader expects a start-up period and plans for it. Roles and rules are clarified explicitly. Early friction is worked through rather than complained about.

What can I do as a leader to put the Team Principle of Development into practice?

Plan a start-up period for every new team, and make that clear to your own superiors as well. Do not measure a young team against a well-established one. Clarify early what would otherwise stay open for a long time: who has which role? Who decides what? How do we treat one another?

How well is the Team Principle of Development supported by research?

Research support: moderate – that groups change measurably over time is established; a fixed sequence of phases that is the same for all teams is not.

Where does the Team Principle of Development come from?

This principle comes from team research. John C. Maxwell has no separate law for it; the idea is only hinted at in “The Law of Dividends.”

What are some examples of the Team Principle of Development?

Four examples show the principle: the Beatles in Hamburg, the Chicago Bulls, Biosphere 2 and the film “Marvel’s The Avengers” (2012).
