When do you need a coach, and when can a team do the work itself?
I'm a team coach, so you might expect me to say every team needs one. I don't believe that, and the research doesn't support it either.
Years ago, in one organisation, we ran four kinds of development side by side: leadership workshops, peer coaching, individual coaching and team coaching. Team coaching had by far the largest impact on long-term behaviour change. It also had the problem every HR leader with more than a handful of teams recognises straight away. It couldn't reach past the top team. There weren't enough coaches, enough budget or enough hours in the year.
If coaching is the only way a team can develop, most of your teams never will. So the useful question isn't 'coach or no coach'. It's which teams need a skilled person in the room, and how everyone else gets real development without one.
What the research says a team can do for itself
The best evidence I know on this comes from Desmond McEwan and colleagues, who pooled controlled studies of team interventions. One of the formats that worked well was the structured team review: a team, working to a structure, examining how it works and deciding what to change. It didn't need an expert delivering content. It needed a structure, and time set aside to use it.
What didn't work was teaching people about teamwork. Classroom content had no measurable effect. Christina Lacerenza's work on leadership training points the same way from the individual side: self-administered learning was notably less effective than practice, feedback and spaced sessions.
Put those together and the line is clear. A team can do this work itself when it has its own data, a structure for reviewing it, and a regular rhythm. Give a team a workbook and a link to some videos and you haven't enabled it. You've left it to it.
When a team needs a coach
In my experience, a team needs someone skilled in the room when:
The team can't safely talk about its results. If people won't say what they think in front of each other, a self-run review just produces polite agreement. Someone outside the hierarchy changes what can be said.
The leader is part of the problem. It's very hard for a team to review its own dynamics when the person running the review is at the centre of them.
The results are split. When half the team sees one reality and half sees another, someone needs to hold that conversation without taking sides.
The team has been round once and nothing moved. A second self-run cycle with the same blind spots usually gets the same result.
The stakes are high. A leadership team mid-restructure, a merger, a new CEO. The cost of getting it wrong is worth the coach's fee many times over.
Most teams, most of the time, aren't in any of those situations. They're busy, reasonably functional, and would get better with a clear view of themselves and a habit of acting on it. One of the best executive teams I ever worked with had just two learning habits: a check-in at the start of every meeting, and a two-question review at the end. The coaching got them started. The habit is what changed them.
A good coach makes themselves less necessary
The coaching engagements I'm proudest of are the ones where the team stopped needing me. Its review habit outlasted my contract. That's the best outcome for the team and, I'd argue, for the coach's reputation too.
So I'd stop treating coaching and self-directed development as competing options. Put coaches where they're non-negotiable. Give every other team the data, the structure and the rhythm. And make sure each coached team leaves with the ability to keep going on its own.
Where TeamHive fits
We built TeamHive to work both ways, because I needed both.
For teams working on their own: the TeamHive 360 gives a team its own data, from members and stakeholders, mapped to the PLUS model. The HiveAI Coach turns that into what it noticed, questions for the team to discuss and strategies to work on, and it can be chatted with whenever the team wants. A Pulse re-test gives the team a regular rhythm and shows it whether anything has moved.
For teams with a coach: the same results give the coach the diagnosis before the first session, and material to design the sessions around. And because the HiveAI Coach stays available between sessions, the work keeps going when the coach isn't in the room.
Across an organisation: the same measure across every team shows you which ones need a coach. Split results, stakeholder views that differ sharply from the team's own, or a team that hasn't moved since its last Pulse are all signals worth acting on. Through Brave Insights and our partners we also train internal coaches and facilitators to run TeamHive with their own teams.
If you'd like to see what your own team's starting point looks like, the Free Team Effectiveness Indicator takes about ten minutes. And if you're designing development across many teams, the research behind PLUS and our earlier piece on starting with the team are good places to start.
