The Trouble with Harmony: When Getting Along Gets in the Way

On 27 January 1986, engineers involved in NASA's Space Shuttle Challenger programme raised serious concerns about the planned launch.

Temperatures at Kennedy Space Center were forecast to be unusually low.

Engineers at Morton Thiokol, the contractor responsible for the shuttle's solid rocket boosters, were concerned about how the cold might affect the rubber O-ring seals.

They recommended against launching under those conditions.

What followed was a series of discussions, disagreements and management decisions.

The initial recommendation was reversed.

The following morning, Challenger launched.

Seventy-three seconds later, the shuttle broke apart, killing all seven crew members.

The subsequent investigation identified serious failures in communication, decision-making and organisational processes.

It's an important and deeply sobering case.

Not because the disaster can be reduced to a simple story about people wanting to get along.

It cannot.

But because it illustrates what can happen when organisations fail to adequately surface, examine and act on important concerns.

And it raises a question that matters in every team.

What happens when agreement becomes more important than getting the decision right?

The comfort of agreement

Most of us prefer working in environments where relationships are positive.

Where people are respectful.

Where meetings are constructive.

Where conflict is limited and everyone appears to be moving in the same direction.

There's nothing inherently wrong with that.

Positive relationships can support wellbeing, cooperation and effective teamwork.

But agreement and alignment aren't the same thing.

And a team that rarely disagrees isn't necessarily a team that makes good decisions.

Sometimes it simply means people have stopped speaking up.

The difference between harmony and psychological safety

One of the most influential contributions to our understanding of team dynamics comes from Harvard researcher Amy Edmondson.

Her research on psychological safety explores the shared belief that a team is safe for interpersonal risk-taking.

That includes asking questions, admitting mistakes, raising concerns and challenging assumptions.

Psychological safety isn't about everyone feeling comfortable all the time.

Nor is it about avoiding difficult conversations.

In fact, psychologically safe environments can make difficult conversations more possible.

Because people are less concerned that speaking honestly will result in humiliation, rejection or punishment.

That's a very different proposition from harmony.

Harmony is about the apparent absence of friction. Psychological safety helps people engage with friction constructively.

When silence looks like agreement

Think about a meeting where a leader presents a decision.

Everyone nods.

Nobody raises a concern.

The meeting ends.

The leader leaves believing the team is aligned.

But what if three people had reservations?

What if someone noticed a potential problem but didn't want to appear negative?

What if a junior colleague had information that challenged the assumptions of the most senior person in the room?

Silence can mean agreement.

But it can also mean uncertainty, resignation, fear or the belief that speaking up won't make a difference.

That's why leaders need to be careful about interpreting a quiet room as a committed team.

Connection isn't the same as compliance

In The Teamfully Model, Connection is one of four dimensions of collective effectiveness.

The others are Competence, Contribution and Collaboration.

Connection encompasses trust, respect, care, closeness and commitment.

But genuine Connection shouldn't require people to agree with one another.

In fact, a meaningful professional relationship may be one in which people feel sufficiently secure to disagree.

Consider the distinction between an Associate and an Ally.

An Associate might work alongside you and fulfil their responsibilities.

An Ally stands with you for a shared purpose.

But standing with someone doesn't necessarily mean agreeing with them.

Sometimes the most valuable Ally is the person willing to say:

I think we're getting this wrong.

Not to undermine the team.

But because the shared purpose matters enough to challenge the current approach.

The problem with groupthink

Irving Janis popularised the concept of groupthink in his 1972 work on group decision-making.

The concept describes circumstances in which pressures towards concurrence can interfere with critical evaluation of alternatives.

It's an influential idea, although subsequent research has challenged aspects of the original theory and shown that group decision-making failures are more complex than cohesion alone.

That's an important distinction.

Close relationships don't automatically produce poor decisions.

And disagreement doesn't automatically produce better ones.

The issue is whether teams have the processes, behaviours and relational conditions needed to examine information, challenge assumptions and make sound judgements.

A team can be cohesive and critically minded.

It can also be fragmented and make terrible decisions.

The goal isn't conflict for its own sake.

It's the capacity for constructive challenge.

Where MAP becomes important

In my work with teams, I use a framework called MAP.

Mission. Approach. Principles.

Mission is our purpose.

Approach is the behaviours through which we pursue that purpose.

Principles are the values that underpin and guide those behaviours.

The distinctions are important.

A team might have a compelling Mission but pursue it through behaviours that contradict its stated values.

A leader might claim that honesty is a Principle while discouraging people from raising uncomfortable truths.

An organisation might talk about respect while humiliating people who make mistakes.

In those circumstances, the problem isn't necessarily the Mission.

It's the disconnect between the values the team claims to hold and the behaviours it actually demonstrates.

Our Principles should guide our Approach. Our Approach should support our Mission.

And that alignment matters most when the stakes are high.

When we're under pressure.

When results aren't going our way.

When someone challenges a decision.

When doing the right thing becomes inconvenient.

The role of leadership

Leaders have an important influence on whether people feel able to speak honestly.

That doesn't mean every suggestion needs to be accepted.

Or that every disagreement should become a prolonged debate.

But it does mean creating conditions in which relevant information and concerns can be raised, considered and responded to appropriately.

A leader might ask:

What are we missing?

Who sees this differently?

What assumptions are we making?

What would make this decision wrong?

And perhaps most importantly:

What have I done that might make someone reluctant to challenge me?

That last question requires a different kind of leadership confidence.

Not confidence that you're always right.

Confidence that you can hear something uncomfortable without making the person who raised it regret speaking.

The strongest teams aren't always the most agreeable

I've worked with teams in which people genuinely liked one another but struggled to challenge behaviours that undermined performance.

And I've seen teams with very different personalities and perspectives find ways to work effectively together.

The difference isn't simply how close the relationships are.

It's whether people can combine trust, competence, contribution and collaboration in ways that support the team's purpose.

Sometimes that means encouragement.

Sometimes it means support.

And sometimes it means a difficult conversation that nobody particularly wants to have.

The Challenger disaster remains a reminder of the seriousness of organisational decision-making failures.

It should never be reduced to a convenient metaphor for team harmony.

But the broader research on psychological safety, voice and team decision-making gives leaders an important question to consider.

Are people agreeing because they genuinely agree—or because disagreeing feels too difficult?

The answer may tell us more about the health of a team than how well everyone appears to get along.
