The Performance Gap: Issue 18

Last week I wrote about decision-making - specifically the gap between the process teams think they use and what actually happens. This week a harder problem to name: the team that looks high-performing from the outside, functions smoothly internally, and is quietly foreclosing the kind of thinking that would make it better.

Some of the most underperforming senior teams are widely regarded as excellent.

They are professionally capable. They are collegial. They manage upwards well and present coherently to the organisation. Meetings are productive. There is no obvious dysfunction. If you asked any member whether the team was high-performing, they would say yes.

What is absent (and what is almost never named, because naming it feels like a complaint) is productive tension. The kind of challenge that produces better thinking. The kind of honest disagreement that surfaces problems before they become expensive. The kind of relationship where one colleague can tell another that their reasoning is weak and the other is genuinely glad to hear it.

In its place is something that looks like alignment but is actually harmony. And harmony, in a senior team, is often the precursor to failure.

The evidence on conflict and performance

The research on this is counterintuitive and robust. Karen Jehn's work on intra-group conflict distinguishes between task conflict (disagreement about ideas, approaches, and priorities) and relationship conflict, which is interpersonal and affective. Relationship conflict consistently reduces team performance. Task conflict, at moderate levels, consistently improves it.

The high-performing teams in Jehn's research were not the ones with the least conflict. They were the ones with the right kind. They disagreed productively about the work while maintaining the relational trust to do so. The teams that performed poorly tended to have either too much relationship conflict or, just as commonly, too little task conflict - having settled into a pattern of mutual accommodation that felt collaborative but was not generating better outcomes.

Why smooth teams suppress good thinking

The mechanism is straightforward. Once a team has developed strong cohesion (genuine liking, shared history, investment in the relationship) the cost of challenging a colleague's thinking rises. The challenge feels like a personal statement. The recipient, consciously or not, hears it that way. Over time, the team learns to signal agreement rather than risk the discomfort, and the quality of collective thinking quietly declines.

Irving Janis, whose work on groupthink I mentioned last week, documented this pattern across historical case studies of major collective decision failures. The common thread was not incompetence. It was the presence of strong cohesion combined with the absence of any mechanism for genuine critical challenge. The team felt good. The decisions were poor.

What productive tension requires

It requires explicit permission, from the leader, given repeatedly and modelled behaviourally. Not the generic instruction to 'challenge each other' but the specific demonstration that challenge is welcome: the leader who invites a named person to find the flaw in their own position, who visibly updates their view when presented with good counter-evidence, and who thanks the person who made them think harder rather than the person who agreed most quickly.

It also requires that the relational foundation is strong enough to hold the tension. Challenge without trust is aggression. Trust without challenge is stagnation. The combination (which is harder to build than either element alone) is what distinguishes genuinely high-performing teams from teams that are performing the appearance of it.

The question for this week

When did someone last tell you your thinking was wrong in a team setting? What was your response - and what did your response signal to everyone who was watching?

Issue 19: When the team changes - why membership transitions are among the most disruptive events a senior team faces, and why leaders systematically underestimate how long recovery takes.
