Ask HN: What Is a COO?

114 points by simonhfrost ↗ HN
Throughout my career I've held exclusively engineering positions. However, I've noticed the parts of my work I enjoy the most aren't necessarily the technical challenges, but instead improvements to process and productivity.

My favourite books are 'Getting Things Done' [0], and 'Deep Work' [1]. I also consistently try to find improvements to communication, requirement clarification, and decision making.

Is this mindset aligned with what would be expected from a COO? I know virtually nothing about the position apart from a line that stuck with me (paraphrased): 'A COO is similar to a CEO, where they have to do the same amount of work but don't get to make any of the decisions'.

Do you have any insights or books/article recommendations for what the role of COO looks like? It would be greatly appreciated

You got it - a COO is focused on process and productivity (among many other things)

A good COO will be almost invisible. The company is firing on all cylinders, departments interact with one another smoothly, everyone is getting what they need…. and the COO is behind the scenes making it all work.

-- a nebulous position - depending on the CEO - usually they are excellent in things the CEO is not - our CEO is really good at thinking about process and productivity - but really bad at thinking about finance and legal - so our COO does that stuff for her --
I think a classic super-star COO example would be Sheryl Sandberg, who was COO of Facebook/Meta. She was practically running the company. Zuckerberg mainly focused on strategy, vision while she made Facebook a well oiled profit machine.
This description matches my experience interacting with multiple COO's at startups of varying size. Most CEO's I know look outwards and to the future, the COO ensures the company executes against the path the CEO has set

The role responsibilities are nebulous and change based on the company, but can generally be described as "whatever is necessary for the business to run". That could mean they focus on running Sales, Marketing, Support, Customer Success, but they could also oversee Operations and in some cases Product.

I know even less. What’s the O?

In my experience (6 companies, variety of verticals), COO responsibilities really vary. I haven't encountered a COO who wasn't interested in improving performance, but I also haven't encountered a COO whose role could be described exclusively as "business optimizer."

On the other hand, I've seen BAs and PMs do the kinds of things you describe, along with plenty of engineers. I've also seen people doing those things who have vague made-up titles unique to the org. In some cases, they were hired for something else, but then ended up what they were good at, and instead advised company leadership.

All of which is to say: if you're looking for a career where you can do more of that kind of thing, you might do better focusing on organizations rather than titles.

Depending upon the size of the firm and the nature of the CEO/COO relationship, they can be anything.

The scope of their job can be everything from ensuring that the office windows get cleaned regularly, to working on a hyperspecific project as a fixer, to overseeing large parts of business strategy that the CEO does not have time or expertise for, to effectively waiting/in training to be a successor to the CEO.

Gross oversimplification: CEO - Works on the business, focuses on the big picture. COO - Works in the business, focuses on the detailed execution.
Shortly after signing on as Chief Operating Officer at Facebook, Sheryl Sandberg was looking to connect with people in a similar role. She called Tim Cook.

“He basically explained nicely that my job was to do the things that Mark (Zuckerberg) did not want to focus on as much,” Sandberg said of the 2007 meeting that lasted several hours with the Chief Operating Officer of Apple Inc.

“That was his job with Steve (Jobs). And he explained that the job would change over time and I should be prepared for that.”

If you've watched The Wire, Stringer's the COO. "And you see this? It's the Queen. She smart, she fierce. She move anyway she want as far as she want. And she, is the go get shit done piece. Remind me of Stringer."
What’s Slim Charles’ title?
Slim is probably a Craig Federighi or Eddy Cue back when Steve Jobs was at the helm. VPs who report directly to the CEO.
what is Prop Joe?
Prop Joe's a King like Avon, except for the other side.
No no, Prop Joe is a member of the board
In my experience the CEO - COO relationship is similar to that between a CTO and a VP Engineering.

If you are the CTO and have a VPE, the VP typically tends to focus inwards, while the CTO has the luxury to care more about outwards topics - strategy, vision, investor relations, business relations etc. The VP focuses on processes, projects, coding standards etc.

It's similar between CEO and COO. If you have a COO you trust, as a CEO you can focus much more outwards about high level issues (strategy, investors, business partners etc). The COO makes sure that the business runs smoothly (hiring, processes, quality of service etc).

I work in C suite for non tech/start up industry, more traditional setting, and could not have explained better than this.

It’s mostly a bifurcation of strategy and execution. The CEO is forward looking and COO is focused on the day to day. Making sure all teams and processes are running smoothly. Helping determine which investments have a high priority, etc. The COO is still very involved in the strategy as well. Because they’ll eventually need to operationalize it.

Pretty much every C level role that gets added as a company grows is to pull away some domain specific stuff from the CEO. The CEO could do it all in theory. COO is usually one of the later additions to the C suite during growth as it usually has a lot of overlap with CEO.

The inward focus aspect is a good way to look at it. Most of these titles date back to the manufacturing days, when the COO was the guy responsible for production, for running the factories (all of the plant managers reported up to him). The CEO had a much broader purview (not only production, but also sales, finance, etc) and perhaps more importantly being the external face of the company to the market and to shareholders.
Some people would say that the VPE has the luxury to care more about inwards topics whilst the CTO tends to focus outwards.

Different strokes for different folks.

> while the CTO has the luxury to care more about outwards topics - strategy, vision, investor relations, business relations etc.

Odd, those are all CEO responsibilities, not CTO ones.

Not in the realm of technology. I.e. what is our strategic technical vision, what do I have to prepare for investors to explain our technical strategy, etc.
Yeah sorry, I meant this of course in the context of a tech organization.

As a CTO you will spend time preparing board meetings, OKR discussions, be part of strategy offsites, handle audits, have stakeholder meetings (CPO, COO, HR), have a part in Allhands, talk to vendors and business partners and of course handle all internal crisises that are escalated to you.

It's definitely a more messy and political work environment that you should take into account when leaving the IC track.

The CEO is a leader, the COO is a manager. The CEO chooses what to do, the COO gets it done.
Sort of a side question: If someone running a company claimed to do all the things in these comments "looking towards the future", "strategy", "investor relations", "business optimization" how would you disprove that?
"Investor relations" and "strategy" sound vague, but in this context they refer to concrete and unambiguous things. If you're not regularly standing in front of investors and showing them slide decks, you're not doing investor relations; if you're not regularly talking to senior leaders to discuss the industry and suggest new initiatives, you're not doing strategy.

"Looking towards the future" and "business optimization" are more squishy, and you can't really specifically disprove that someone's doing them on an ongoing basis. But you can often disprove it retrospectively, if you see that the business is run increasingly poorly or clearly failed to account for some big new trend.

let dog = 'dog'; let food = 'scraps'

console.log(`${dog} gets ${food}`);

dog = 'coo'; food = 'what ceo doesn\'t wanna do';

console.log(`${dog} gets ${food}`);

As a rough parallel, think Game of Thrones - the COO is the Hand of the King. As in the novels, specifics vary widely depending on those involved and how much/what the leader wants to delegate.
"The king eats, and the hand takes the shit."
(comment deleted)
"Operations" and COO, in my ignorance, I find extremely domain-specific.

I think of Operations from technology perspective - datacentre and servers and SRE and ITIL; processes like release / incident / problem management.

In many other businesses, Operations/COO is much more focused on business finances, supply chain, paying the bills, accounting, etc.

From that experience, while I too would love to have better understanding and will read this thread eagerly, I think we all need to be careful to "domain scope manage" it.

The person I've been missing my whole life :)

Writing code is fun, building stuff is fun. Handling tax stuff, invoicing, managing office space and connecting various departments is a major PITA.

I don't think there is any one specific answer. It is going to vary a lot company to company and will depend highly on the CEO. Places I have worked, the CEO & COO operate very closely together with the COO usually focusing more on the internal company functions while the CEO focused more externally.
I never liked 'Getting Things Done'. It's the most repetitive book I've ever read. It could be a 5-page article, but David Allen decided to write a ~300 pages book by repeating the same idea over and over.
I'm a pretty faithful GTD user, and I love the book, because I need to hear some of those things a hundred times, but also because there's nuance to the method beyond a few mechanical basics. I've met a lot of people who say they do GTD and haven't read the book or only skimmed it, and invariably they seem to basically just use to-do lists. That's a good first step, but it's a terrible place to stop.
A COO does what the CEO doesn't want to do.
In short, the best analogy I have for COO is from the Navy. The Captain is the CEO. The Executive Officer is the COO.
Where I work, most of the persons time is spent making sure customers/clients/partners/suppliers/tenants/banks/investors/employees/contractors etc etc honor commitments. Cuz most people dont. For all kinds of good and bad reasons. And ofcourse same story works in the opposite direction too.
