C'est lors de la transition vers un premier poste de responsable que votre réserve de futurs dirigeants se fissure

En bref : Promoting your strongest individual performer into management rarely creates a strong manager. The first leadership step is a genuine career change, and treating it as a deliberate transition protects both your people and your pipeline.

The best individual contributor and the best manager are doing two different jobs

Early in my career I watched a brilliant engineer get promoted on a Friday and arrive on Monday responsible for six people, a roadmap, and a set of conversations he had never been trained to have. He was still the sharpest technical mind in the room. He was also, almost overnight, the reason his team felt adrift. Nothing about his ability had changed over the weekend. His job had. The skill that earned the promotion, personal excellence at the craft, is close to irrelevant to the skill the promotion now demands, which is producing results through other people. Most organisations keep treating these as one continuous ladder. They are two different jobs, and the move between them is a real career change that we consistently underestimate. We reward mastery of the work by asking people to stop doing the work, then act surprised when the transition is hard.

Promoting your strongest performer rarely produces your strongest manager

Gallup’s long-running research on managers is blunt about the odds. It finds that about one in ten people naturally possess the talent to manage others well, with another two in ten showing some of the raw material. That leaves most promotions drawing from a shallow natural pool. The selection itself is usually wrong, too: Gallup reports that companies choose the candidate with the right talent for the job only eighteen percent of the time. When we default to promoting whoever produced the most last quarter, we optimise for the wrong signal. Individual output tells you almost nothing about someone’s instinct to coach, to give hard feedback cleanly, to hold a standard without smothering people, or to feel genuine satisfaction from a teammate’s win rather than their own. Those are the muscles the new role runs on, and the annual sales number never measured a single one of them.
