The Hidden Cost of an Unbalanced Team (And How to Fix It)
Most teams don’t fail dramatically. They underperform quietly.

Deadlines slip by a week. Then a fortnight. Meetings run over, decisions are postponed, and the same problems return every quarter but perhaps in a slightly different guise.
Projects start with enthusiasm but somehow lose momentum. Frustration builds. Good people try to work harder, yet the results don’t seem to improve.
And eventually, someone asks the obvious question:
“Do we have the right people in this team?”
It’s a reasonable question. But it may not be the best question to ask.
Because the problem isn’t always the quality of the people. It’s often the balance of the behavioural contributions they bring to the team.
And that’s where Belbin Team Roles can make a real difference.
A better question to ask can be “Do we have the right mix of behaviours in the team?”
Why Better People Aren’t Always the Answer
One of the most interesting findings from Dr Meredith Belbin’s original research at Henley Management College was that teams of highly intelligent, capable individuals did not necessarily outperform everyone else.
Quite the opposite.
During the research, teams composed of exceptionally able individuals were expected to perform well.
Frequently, they didn’t.
Despite their intellectual ability, these teams often became caught up in analysing problems, challenging each other’s arguments and defending their own positions. Considerable energy went into discussion, but not enough into reaching decisions and delivering results.
The problem wasn’t a shortage of ability. It was how that ability was combined and used.
Belbin’s research helped establish a key principle that remains highly relevant to organisations today:
A team of talented individuals isn’t necessarily a talented team.
What matters is having a complementary mix of behaviours, with people contributing different strengths towards a shared objective.
This principle became central to the development of the nine Belbin Team Roles.
And it helps explain why some teams consistently outperform others, even when their members have similar levels of experience, qualifications and technical expertise.
What Does an Unbalanced Team Actually Look Like?
An unbalanced team doesn’t necessarily look dysfunctional.
Sometimes everyone gets along. Everyone works hard. Everyone appears perfectly competent.
The warning signs are usually more subtle.
In Belbin terms, problems can arise when important Team Role contributions are missing, when particular behaviours dominate, or when people compete to make the same contribution.
Let’s look at five common examples.
1. Plenty of Ideas. Very Little Delivery.
We’ve probably all encountered this team.
Meetings are energetic. New ideas are enthusiastically discussed. Opportunities are everywhere, and there’s always another exciting initiative around the corner.
The problem?
Very little actually gets finished.
What might be happening?
The team may have plenty of Plant and Resource Investigator behaviour.
Plants generate original ideas and creative solutions. Resource Investigators explore opportunities, develop contacts and bring fresh possibilities into the team.
Both are enormously valuable contributions.
But without sufficient Implementer behaviour to turn ideas into workable plans, and Completer Finisher behaviour to ensure those plans are properly delivered, progress can stall.
The solution isn’t to discourage creativity.
It’s to make sure the team has the complementary strengths needed to turn good ideas into results.
After all, an excellent idea that never gets implemented is just an idea.
2. Reliable Delivery. Very Little Innovation.
Now consider the opposite situation.
This team is organised, disciplined and dependable. Processes are followed, deadlines are monitored, and established work is completed efficiently.
Everything appears to be running smoothly.
Until something changes.
A new competitor enters the market. Customer expectations shift. Technology changes the way the work needs to be done.
Suddenly, the team struggles to adapt.
What might be happening?
There may be strong Implementer and Completer Finisher contributions, but insufficient Plant or Resource Investigator behaviour.
The team may be excellent at delivering what it already knows how to do, but less comfortable questioning established approaches or exploring alternatives.
The answer isn’t to abandon discipline and structure.
It’s to introduce more opportunity-seeking and creative thinking alongside those existing strengths.
The best teams need to deliver today’s priorities while remaining alert to tomorrow’s challenges.
3. Plenty of Harmony. Not Enough Challenge.
Some teams are exceptionally pleasant places to work.
Relationships are good. People are considerate. Disagreements are rare.
On the surface, everything looks healthy.
But important decisions take too long. Difficult conversations are avoided. Nobody wants to challenge an idea that everyone else seems happy with.
The team agrees in the meeting, then raises its concerns afterwards.
What might be happening?
Strong Teamworker and Co-ordinator behaviour may be helping the team maintain positive relationships and work collaboratively.
However, there may be insufficient Shaper behaviour to introduce urgency and challenge, or Monitor Evaluator behaviour to question assumptions and assess proposals critically.
The result can be a team that values agreement more than progress.
Constructive challenge isn’t the enemy of teamwork. Often, it’s what makes teamwork effective.
4. Endless Analysis. Few Decisions.
This team takes decision-making seriously.
Every option is examined. Risks are identified. Additional information is requested.
Unfortunately, the discussion never quite reaches a conclusion.
Another meeting is arranged.
Then another.
What might be happening?
The team may have considerable Monitor Evaluator and Specialist strengths.
Monitor Evaluators provide objective judgement and careful consideration of alternatives. Specialists contribute valuable depth of expertise.
But without someone creating momentum, clarifying the decision or organising the next steps, analysis can become an end in itself.
The team doesn’t necessarily need less information.
It needs a clear process for moving from analysis to action.
5. Too Many People Trying to Lead.
A strong Shaper can bring much-needed drive and determination to a team.
But what happens when several people are equally determined to set the direction?
Instead of additional momentum, the team may experience competing priorities, frustration and conflict.
Similarly, two strong Co-ordinators may both attempt to organise the group’s work or direct discussions.
What might be happening?
This isn’t necessarily about difficult personalities.
It may reflect overlapping Team Role preferences, with people competing to make similar contributions.
The answer isn’t always to remove someone or suppress their strengths.
It may simply involve clarifying responsibilities, agreeing decision-making authority and giving each person a distinct area in which to contribute.
These examples illustrate some common potential issues. The same Team Role combinations can work very differently depending on the people, the task and the wider working environment.
The important point to note is that behavioural imbalance provides another potential explanation for problems that might otherwise be attributed to individual performance or personality.
The Hidden Business Cost of an Unbalanced Team
Here’s where the problem becomes particularly important for managers and business leaders.
An unbalanced team rarely generates a neat financial output labelled “the Cost of Poor Team Balance”.
Instead, the costs appear elsewhere.
They show up as:
- Slow decision-making: Meetings consume valuable management time without producing clear outcomes.
- Poor execution: Promising ideas fail to translate into completed projects.
- Rework and quality problems: Errors, omissions and missed requirements create avoidable additional work.
- Unnecessary conflict: Friction between colleagues reduces collaboration and diverts attention from the task.
- Missed opportunities: Teams become inward-looking and fail to recognise developments outside their immediate environment.
- Employee frustration: Capable people become disengaged when their strengths are overlooked or constantly underused.
- Management time: Leaders spend increasing amounts of time resolving recurring problems rather than improving performance.

Individually, these problems may seem manageable.
Collectively, over a year, their effect on productivity, performance and profitability can be considerable.
And because the consequences are spread across different activities, the underlying causes can remain hidden.
A Simple Way to Assess the Cost
Rather than relying on generic productivity statistics, start with your own organisation.
Consider:
- What did the last delayed project actually cost?
- How many hours are spent in meetings that fail to reach decisions?
- What did the last preventable quality problem cost to put right?
- How much management time is absorbed by recurring conflict or poor collaboration?
- What opportunities have been missed because nobody was looking beyond the immediate workload?
Not every one of these problems will be caused by Team Role imbalance.
But if the same patterns keep appearing, it’s worth investigating whether the team has the behavioural strengths its work requires.
The cost of doing nothing may be greater than it first appears.
Why Do Teams Become Unbalanced?
Very few organisations deliberately build an unbalanced team.
Most teams are assembled using three perfectly sensible criteria:
- Skills: Who has the technical knowledge required?
- Experience: Who has successfully undertaken similar work?
- Availability: Who is available to join the team?
All three matter.
But none necessarily tells us how someone will behave when working with others.
Belbin distinguishes between a person’s functional role - their job, responsibilities and technical expertise - and their Team Roles, which describe the behavioural contributions they make within a team.
Two people with similar qualifications and experience may bring very different behavioural strengths to the same project.
One may generate ideas and spot opportunities. Another may organise the work and ensure that it gets completed.
Both are valuable.
But if we only assess their technical backgrounds, experience or qualifications, we may overlook those differences entirely.
Three Further Causes of Team Imbalance
Recruiting in our own image
Managers can naturally favour candidates whose approach to work feels familiar.
Over time, repeated recruitment decisions may produce a team with similar behavioural preferences and fewer complementary strengths. Watch our webinar about Breaking Bias with Belbin.
Restructuring and changing team membership
When organisations restructure or reduce headcount, the work still needs to be done.
Losing one individual may also mean losing a particularly valuable Team Role contribution.
The impact might not be immediately obvious. It may emerge later through missed details, weaker collaboration or reduced momentum.
Changing business priorities
A team that is well balanced for routine delivery may be less suited to leading a major transformation programme.
Equally, a team assembled to develop innovative ideas may need a different balance of contributions once those ideas move into implementation.
The right team balance depends on what the team is being asked to achieve.
And that balance needs to evolve.
How Belbin Helps Identify the Gaps
This is where Belbin offers a particularly practical solution.
Rather than relying entirely on assumptions about how people contribute, Belbin provides a structured way to assess individual behavioural strengths and examine how they fit together.
The process begins with each team member completing a Belbin Self-Perception Inventory.
This identifies the Team Roles they believe best describe their contributions.
Ideally, this is supplemented by Observer Assessments, in which colleagues provide feedback about the behaviours they actually experience.
Observer feedback is especially valuable because how we believe we contribute isn’t always the same as how others perceive the way we behave.
Belbin recommends inviting around six Observers, with a minimum of four required to produce a report incorporating Observer feedback. Ideally, those colleagues should have worked closely with the individual for at least three months.
The resulting Belbin Individual with Observers Report identifies:
- Preferred Team Roles: Behaviours someone naturally enjoys and tends to demonstrate strongly.
- Manageable Team Roles: Contributions they may be able to adopt effectively when required.
- Least Preferred Team Roles: Behaviours they may find less comfortable or less natural.

The next step is to combine these individual insights in a Belbin Team Report.
This provides an overview of the team’s behavioural composition, helping identify:
- Strengths that are well represented.
- Contributions that may be missing or underrepresented.
- Areas of overlap or potential competition.
- Opportunities to distribute tasks more effectively.
- Ways of combining individual strengths to improve team performance.
The real value lies in moving from a general feeling that something isn’t working to a more specific discussion about which contributions are needed, who can provide them and how the team can use them more effectively.
Does Every Team Need All Nine Team Roles?
Not necessarily.
Firstly, a team doesn’t need nine people to cover the nine roles.
Most individuals have more than one preferred Team Role and may be able to contribute effectively in other roles when required.
Secondly, not every team needs all nine behaviours in equal measure, or at every stage of its work.
A team responsible for delivering a complex, highly regulated project may particularly value Implementer and Completer Finisher contributions.
A team exploring new markets may require greater Resource Investigator and Plant contributions.
The objective isn’t to produce a perfectly symmetrical Team Role chart.
It’s to ensure the team has access to the right behavioural contributions for the work it needs to deliver.
Six Practical Ways to Fix an Unbalanced Team
Once behavioural gaps and overlaps become visible, the solutions are often more straightforward than people expect.
Importantly, many improvements can be made without recruiting additional staff or changing the membership of the team.

1. Make Better Use of Manageable Team Roles
People aren’t limited to one Team Role.
Someone who doesn’t naturally prefer a particular contribution may still be capable of adopting it when necessary.
For example, a team with limited Monitor Evaluator behaviour could ask an individual who has this as a manageable role to take responsibility for reviewing assumptions and challenging a proposal before a decision.
The key to success here is making the expectation explicit, rather than hoping someone will question the plan. Agree who will do so, with their buy-in.
2. Allocate Work According to Strengths
Too often, responsibilities are allocated according to job title, seniority or simple availability.
Belbin offers another consideration: who is behaviourally best suited to the task?
Think about the person who naturally spots errors and omissions. Could they take greater responsibility for final quality checks?
Or the individual who effortlessly develops external relationships. Could they contribute more to identifying opportunities and building partnerships?
Playing to strengths doesn’t mean ignoring job requirements or allowing people to avoid every less-preferred task.
It means using the available talent more intelligently.
And often, the work gets done more effectively because people are contributing in ways that suit them.
3. Build Missing Contributions into the Process
Sometimes a team genuinely lacks a particular behavioural strength.
Where nobody can readily provide it, a more structured process may help compensate.
For example:
- Introduce a formal challenge stage before important decisions.
- Use quality checklists and sign-off points.
- Set clear decision deadlines to prevent endless analysis.
- Allocate responsibility for monitoring external opportunities.
- Build regular progress reviews into project delivery.
These approaches don’t replace the contribution of an individual Team Role completely, but they can reduce the impact of a Team Role gap.
4. Manage Overlaps Rather Than Suppressing Strengths
Having several people with similar Team Role preferences isn’t automatically a problem.
The difficulty arises when their contributions compete rather than complement one another.
Two strong Shapers, for example, may be highly effective when they have separate areas of responsibility and a shared understanding of priorities.
Without that clarity, they may compete for direction and authority.
Similarly, strong Co-ordinators can work effectively together when decision-making responsibilities are agreed.
The aim isn’t to reduce people’s strengths.
It’s to create the conditions in which those strengths work together.
5. Consider Team Balance When Recruiting
When a vacancy arises, it creates an opportunity to look beyond the immediate job description.
Yes, technical capability, experience and qualifications remain essential.
But what behavioural contribution would most benefit the team?
Could the team benefit from someone who brings more creative thinking, stronger organisation, better relationship-building or greater attention to detail?
A Belbin Job Report can help define the behavioural requirements of a role.
This information can then support recruitment decisions alongside interviews, experience, technical assessment and other relevant evidence.
Recruitment should never be reduced to finding a particular Team Role label either.
It’s about understanding what the role and team genuinely need.
6. Look Beyond the Immediate Team
Not every behavioural gap requires a permanent appointment.
Sometimes the solution lies elsewhere in the organisation.
A colleague with strong Resource Investigator preferences might be involved during the early stages of a business development project.
A Completer Finisher from another function might contribute to an important final review.
A Monitor Evaluator could be invited to challenge a proposal before a major investment decision.
These contributions can be valuable even when individuals aren’t permanent members of the team.
Sometimes the missing strength is already available.
We simply haven’t thought to use it.
Don’t Try to Fix People. Fix How the Team Works.
There’s another important lesson from Belbin.
Every Team Role brings characteristic strengths and potential allowable weaknesses.
These weaknesses are often the flip side of a valuable contribution.
For example, a Plant may generate highly original ideas but have less interest in practical detail.
A Completer Finisher may produce work to exceptionally high standards but worry excessively about mistakes.
An Implementer may be exceptionally dependable but initially resist changes to an established plan.
The answer isn’t to try and develop people so they lose those characteristics.
In many cases, a more effective approach is to recognise the strengths, manage the associated weaknesses and combine people whose contributions complement one another.
That doesn’t mean unacceptable behaviour should be excused as an allowable weakness. Individuals remain responsible for how they work with others.
The purpose of Belbin is to help teams recognise differences constructively, rather than trying to make everyone behave in the same way.
We don’t necessarily need well-balanced individuals. We need individuals whose contributions balance one another.
A Word of Caution: Belbin Is About Behaviour, Not Labels
Belbin Team Roles describe behavioural preferences and contributions.
They aren’t fixed personality types, permanent categories or measures of someone’s overall capability.
An individual may demonstrate different Team Role behaviours depending on their responsibilities, colleagues, experience and working environment.
Equally, a gap identified in a Team Report doesn’t automatically mean that a particular contribution is entirely absent.
Sometimes people have strengths they rarely get the opportunity to demonstrate.
A creative colleague may have stopped sharing ideas because previous suggestions were dismissed.
Someone who could provide constructive challenge may remain quiet because disagreement isn’t welcomed.
Before concluding that a team needs different people, it’s worth asking whether its existing members have sufficient opportunity to use the strengths they already possess.
Belbin should support constructive development and better teamwork, not be used to label employees or as a basis for redundancy selection.
Five Questions Every Team Leader Should Ask
If you’re concerned about your team’s performance, start with these questions:
- What is this team’s purpose? Which behavioural contributions are most important to achieving those objectives?
- Where do we regularly lose momentum? Is it generating ideas, making decisions, organising delivery or completing the final stages?
- Which strengths are we relying on too heavily? Are one or two individuals carrying responsibilities that could be shared more effectively?
- Where do we have overlapping contributions? Are people complementing one another or competing to play the same role?
- Are we making full use of the strengths already available? Or are some valuable contributions being overlooked, discouraged or underused?
These questions won’t provide every answer.
But they can help shift the conversation away from assumptions about individual shortcomings towards a more constructive examination of how the team operates.
High-Performing Teams by Design
The difference between a high-performing team and an underperforming one isn’t always the calibre of the people involved.
Often, it’s how effectively their strengths are recognised, combined and used.
A team can have exceptional technical capability and still struggle with communication, decision-making, innovation or delivery.
Equally, a group of relatively ordinary individuals, working together with complementary strengths and a shared purpose, can achieve exceptional results.
That’s the real value of understanding Belbin Team Roles.
Not simply knowing what each person does best, but understanding how those individual contributions fit together to create a more effective team.
And importantly, how to recognise and address the gaps before they become expensive problems.
The good news?
Improving team balance doesn’t always require new people, a major restructuring exercise or another expensive initiative.
Sometimes it starts with a better understanding of the people you already have.
Is Your Team Working Hard but Not Delivering the Results It Should?
At Belbin Scotland, we help organisations understand the behavioural strengths, gaps and overlaps within their teams, and turn those insights into practical improvements.
A Belbin Team Report provides a structured starting point, bringing individual Team Role profiles together to help identify how the team can work more effectively.
Combined with a facilitated team workshop where appropriate, it can support better communication, clearer responsibilities, improved decision-making and more consistent delivery.
If you recognise some of the warning signs described in this article, we’d be happy to explore whether Belbin could help.
