A couple of months into leading a data platform team, and very much feeling the gap between "good engineer" and "good manager," I did something that a year ago I'd have found faintly ridiculous: I signed up for a Harvard online management course. From my kitchen table, in the middle of a pandemic, I studied Management Essentials. And I want to write about it honestly — what a formal management education genuinely gave me, and the large and essential part that no course could — because I think both halves are worth knowing before you spend the time.

Why I reached for it

The honest impetus was that I'd been promoted into a role I had no formal preparation for. I'd been trained, over years, as an engineer. I had been trained, over exactly zero years, as a manager. And I'd just started doing the second thing full-time, mostly by instinct, mostly by copying managers I'd respected and avoiding the patterns of ones I hadn't. That's a normal way to become a manager — most people do it that way — and it left me with a nagging sense that I was improvising a discipline that actually has a body of real knowledge behind it.

So the course was, in part, the same impulse as the certifications I'd been collecting: a wish to systematise something I was picking up piecemeal, to replace "winging it competently" with "understanding the thing properly." And in a pandemic, with the usual informal ways of learning a role — watching other managers up close, the corridor mentorship — all shut off by remote work, formal study filled a gap that osmosis normally would.

What it genuinely gave me

I want to be fair to it, because it delivered real value, and the sneering "you can't learn management from a course" take is lazy. What a good, structured management education actually gave me:

  • A vocabulary and a frame. So much of what I'd been doing by instinct turned out to have names, structure, and a considered body of thinking behind it. Having the concepts — being able to think "this is a delegation problem" or "this is about aligning incentives" rather than just a vague sense that something's off — is genuinely clarifying. Naming a thing is the first step to handling it deliberately rather than reactively.
  • Other people's expensive mistakes, for free. The case-study method — Harvard's whole thing — is essentially a way to live through management situations you haven't yet faced, and learn from decisions (good and bad) that other people paid for. It stretched my sense of what situations look like before I'm standing in one, which is worth a lot when the alternative is learning each lesson personally and expensively.
  • Permission to take the craft seriously. Perhaps the subtlest benefit: the course treated management as a genuine discipline worth studying, which quietly gave me permission to invest in getting good at it, rather than treating it as the thing you do around the real (technical) work. That reframing mattered.

The essential part it couldn't give me

But here's the honest boundary, and it's the same boundary I keep finding at the edge of every certification and course: the frame is not the doing, and management lives almost entirely in the doing.

A course can teach you the concept of a difficult conversation. It cannot give you the specific, sweaty-palmed experience of having one — with this person, whom you like, about this real problem, where the words matter and the relationship is on the line and there's no model answer. It can teach you frameworks for motivation; it cannot tell you what actually motivates the particular human sitting across from you (or, this year, in the other Zoom window), which you can only learn by paying attention to them specifically, over time. It can give you principles of good judgement; it cannot supply the judgement itself, which is forged only by making real calls with real consequences and living with how they land.

Management, more than most disciplines, is practice, not knowledge — and practice is exactly the thing a course, by its nature, has to leave out. The course gave me the map. The territory is walked alone, in real conversations with real people, and it's genuinely hard in a way no amount of studying softens.

A management course gives you the vocabulary, the frameworks, and other people's mistakes. It cannot give you the one thing the job actually runs on: judgement about specific real humans, which only accrues from leading them, imperfectly, and paying attention to what happens.

Was it worth it?

Yes — with the same clear eyes I bring to any certification. It was worth it as a complement to the doing, not a substitute for it. It gave structure and vocabulary to the experience I was already accumulating, and it accelerated my sense of the shape of the discipline. What it didn't do — couldn't do — was make me a good manager, because that's a thing you become slowly, in practice, by leading actual people and learning from how it goes.

There's a nice symmetry here with what I wrote about passing my product-owner certification: the exam or the course makes you certified; the room makes you capable. I'm a little better equipped than I was, and I know exactly which part of "good manager" is still entirely ahead of me — the part that isn't in any syllabus, that I can only earn by continuing to lead this team, month after month, and paying close attention to the humans in it. The Harvard course was a good use of a strange, shut-in autumn. But the real education is happening in the standups, the one-to-ones, and the hard conversations, none of which came with a certificate — and all of which are teaching me more than Harvard could.
