Your best specialist is not your next manager

Somebody on your team is exceptional at the work. They are the one you go to when the numbers have to be right, or the system has to hold, or the client cannot be lost. When a promotion comes up, the decision feels obvious. They have earned it. Everybody agrees. You make them a manager.

Six months later you have a manager who is struggling and you no longer have the person you used to go to. You have lost two people, and only one of them has left.

We have each done this. It is worth being precise about why it keeps happening, because the usual explanation — that some people simply cannot manage — is both unkind and largely wrong.

The promotion is doing three jobs at once

In most organisations, promotion is the only instrument available for three separate purposes: paying someone more, recognising that they are excellent, and changing what they do all day.

Those are different things, and bundling them means the third one arrives as a side effect of the first two. Nobody sat down and decided that the best analyst should stop analysing. What was decided was that she should be paid what she is worth and told publicly that she matters, and management was the only envelope those came in.

So the first question is not who deserves it. It is whether you have any other way to pay and recognise someone. If you do not, you will keep converting your strongest practitioners into your weakest managers, and the conversion will keep looking like a reward.

What actually changes

The work changes completely, and we think this is understated in most handovers.

A specialist is judged on what they produce. A manager is judged on what other people produce, which means their day is spent on things that show no output of their own: unblocking, sequencing, absorbing bad news, sitting with someone who is not coping, deciding between two defensible options with insufficient information.

For someone who has built their professional identity on being the person with the right answer, this is not a promotion in any felt sense. It is a demotion into ambiguity. The satisfaction they used to get from finishing something is simply gone, and it is replaced by a diffuse anxiety that they are not doing anything.

Nobody warns them about this. We did not warn anybody either, for a long time.

What we would do instead

Three things, none of them complicated, all of them requiring a decision at the top.

Build a second ladder. A senior specialist track with real seniority, real money and real standing — not a consolation title. This is common in engineering and rare everywhere else, and there is no reason it should be. A principal analyst who never manages anyone can be worth more to a bank than a mediocre head of department.

Make the choice explicit, and give it a way back. Say plainly: this is a different job, not a bigger version of yours. Try it for a year. If it is not for you, returning to the specialist track is a legitimate outcome and not a failure. Almost nobody offers this, which is why almost nobody admits it is not working.

Train before, not after. Most first-time managers here are handed a team and a target and left to work out the rest by watching whoever managed them. That is how bad management reproduces itself for a generation. A few days of real preparation before the first difficult conversation is worth more than a course two years in.

The part that costs something

Several of us teach, coach and mentor, and we hold that the measure of our work is not only the organisations we change but the leaders we leave behind.

Which means this: sometimes the right answer is that your best person should stay exactly where they are, being excellent, paid well, and never managing anyone. Saying so out loud costs you a tidy succession plan and a straightforward headcount line.

It is still the right answer, and the alternative is one you have probably already watched happen.
