When you've become the bottleneck on your own team
The Practitioner stage
If you are the person every hard problem gets brought to, and your team has quietly stopped bringing you their own judgement, you are probably leading from the Practitioner stage.
It is a genuine achievement, not a deficit — and it has a specific ceiling. The frame works beautifully right up to the point where you can no longer personally hold the whole problem.
A genuinely excellent leader starts producing a mediocre organisation, and cannot see why, because every individual decision they made was right.
What it looks like
Attention goes to the problem. Not to the goal the problem sits inside, not to the people bringing it, not to the system generating it — the problem itself, in front of you, solvable.
You fix things personally, often faster than delegating would take, which is true and is also why it never stops. You have high standards and little patience for work that misses them. When someone disagrees, you explain — because from inside this frame disagreement is a gap in the other person's information. Usually they would agree if they had the facts. They usually would, which is what makes the pattern so durable.
You are respected, and difficult to work for once the team gets past about six people.
The move that earned it
Every stage represents a real developmental achievement, and it is worth naming this one, because treating the first stage as a starting deficit misunderstands the whole scale.
The Practitioner has built a self that can be measured against an external standard and survive it. That sounds small. It means having a craft you can be measurably bad at, submitting your work to a judgement that is not yours, and staying in the room. Many people never fully do this — they arrange their working lives so nothing they produce is ever cleanly assessable.
Where it stops
The ceiling arrives with scale, and it arrives abruptly. Facing a problem too big to solve personally, the Practitioner does not switch approach. They solve harder — longer hours, more detail, more personal intervention on the parts still within reach.
Your team stops developing. Not from neglect, but from being consistently corrected by someone who is consistently right. Nobody grows judgement in an environment where their judgement is routinely overwritten by better judgement, and the correction is usually gracious, which makes it harder to object to.
Disagreement stops being available. Your response to it is explanation, and the explanation is usually good, so people stop offering. This happens gradually and invisibly. You experience it as the team increasingly agreeing with you, which is pleasant.
You become the ceiling. The unit can be exactly as good as one person’s attention, and one person’s attention is finite.
What moves you from here
The opening question is what the competence is actually for. Not whether the standards are right — they usually are — but what happens to everyone else when the standards are held by you personally rather than built into the work.
The move is toward holding an outcome larger than your own contribution to it, and organising other people around that, including accepting an approach you would not have chosen because it gets there.
