What Does a COO Do? Roles, Responsibilities, and Salary

Key Takeaways

• A COO turns company strategy into execution, overseeing the operations and people that carry out the CEO's priorities.
• The job changes with a company's size and industry, and with how the CEO chooses to divide the work.
• Many companies treat the COO as the CEO's second-in-command, and some use the role to prepare a successor.
• Most COOs reach the role through progressively broader leadership experience, and the routes vary widely.

Most people have a working sense of what a CEO does: set the company's direction and answer to its board. The chief operating officer is harder to picture, partly because the job looks different at almost every company that has one.

The short answer to "What does a COO do?" is that the COO turns strategy into execution and keeps the organization running well day to day. The longer answer depends on the business and on the CEO the role supports.

What Is a COO?

A chief operating officer (COO) is a senior executive who oversees a company's operations and works closely with the CEO to carry out the business strategy. In many companies, the COO is considered the CEO's second-in-command, although reporting structures vary.

Each company defines the role of chief operating officer around its own needs and the CEO's strengths. As a result, two COOs with the same title can oversee very different parts of the business.

What Does a COO Do? Key Roles and Responsibilities

The fuller answer to "What does a chief operating officer do?" starts with a simple idea: a COO turns company strategy into execution by coordinating people, processes, resources, and performance across the organization. Most COOs work through other leaders, overseeing the managers and systems that get the work done. Department heads for areas such as operations, supply chain, customer service, and sometimes human resources often report to the COO.

Turns strategy into execution

The CEO and board set priorities, and the COO converts them into operating plans with measurable goals and named owners, each with a deadline. If the company decides to open a new region, the COO works out the staffing plan and budgets the expansion needs, then sets the milestones leaders will be held to. The same work applies when a company rolls out a new enterprise software system.

Oversees day-to-day operations

At the executive level, day-to-day operations means how resources get allocated and how work flows between teams. The COO moves budget and people when priorities change and steps in when a problem blocks execution. Operations managers and project managers each run one function or project, while the COO is accountable for how all of those pieces work together.

Tracks performance and solves operational problems

COOs monitor key performance indicators and review results against goals, looking for the bottlenecks and inefficiencies behind any miss. They use those numbers to decide what should change. If order fulfillment slips, a COO wants to know whether the cause is staffing or a supplier, and then fixes the part that's failing.

Aligns departments and leads cross-functional initiatives

Departments tend to optimize for their own goals, and the COO keeps them working toward the same company priorities. That often means leading cross-functional initiatives, such as a product launch that needs engineering and customer support on the same timeline, and settling disagreements between department heads. When an issue affects the whole company, such as a supply disruption, the COO brings it to the CEO with options. Across all four areas, the COO's job is to make the company's operating model work.

COO vs. CEO: What's the Difference?

The CEO is responsible for the company's overall direction and answers to the board, while the COO focuses on execution and operational performance. In a typical week, a CEO might spend more time with the board and investors, while a COO spends more of it with department heads reviewing operating results.

Area	CEO	COO
Primary focus	Vision and long-term strategy	Execution and operations
Orientation	Internal and external leadership	Primarily internal execution
Reports to	Board of directors or owners, depending on structure	CEO
Main time horizon	Long-term direction	Current and near-term execution
Core accountability	Overall company performance	Operational performance

The COO and CFO are separate C-suite roles. The COO oversees operations across the business, while the CFO leads the finance function. In most companies, both report to the CEO, and which one carries more authority depends on how the CEO structures the team.

How the COO Role Changes by Company

The COO's scope depends on the size and stage of the company, and on the industry it operates in.

By company size and stage

At startups and scale-ups, the COO often takes a broad remit, covering the areas a founder can no longer manage alone. When Facebook hired Sheryl Sandberg as COO in 2008, the company said she would help it scale operations globally and manage functions including sales, marketing, human resources, and communications. Many early-stage companies leave operations with the founders until the business needs a dedicated COO.

At large enterprises, the COO usually has a more defined scope and may coordinate several business units or senior executives. Some companies also use the role to prepare a successor: Apple named its COO, Tim Cook, as CEO in 2011 under its succession plan. In executive search firm Crist Kolder Associates' 2025 data, the COO or president seat was still the most common step to CEO at Fortune 500 and S&P 500 companies, at nearly 44%. Other COOs stay in the role for years.

By industry

Industry shapes where a COO spends the most time:

• Manufacturing: production and supply chain
• Retail: store operations and fulfillment
• Technology: customer success and scaling operations as the company grows
• Professional services: service delivery and staffing

COO Salary and Job Outlook

The Bureau of Labor Statistics (BLS) counts COOs among chief executives, the same category as CEOs, so its figures describe the broader executive market and COO pay has to be estimated from other sources. Useful reference points include:

• Chief executives: median annual wage of $213,990 in May 2025, according to BLS. Because the category includes CEOs, treat it as an upper reference point.
• General and operations managers: median of $105,770 in May 2025, a reference point for the operations leaders who often move toward COO roles.
• Job outlook: BLS projects employment of top executives to grow 5% between 2025 and 2035, faster than the 3% average for all occupations.
• COO-specific estimate: Payscale's self-reported data puts the average COO base salary at about $151,000 in 2026, with most falling between roughly $82,000 and $255,000 before bonuses and profit sharing.

COO pay depends on company size, industry, experience, bonuses, and equity, and the last two can add substantially to base salary at larger public companies. BLS notes that total compensation for corporate executives often includes stock options and performance bonuses. Location also plays a role: California's concentration of large employers keeps the average MBA salary in California above most other states.

Skills Every COO Needs

The COO skill set combines hands-on operating knowledge with the ability to lead people across the company:

• Operational and analytical depth: understanding how the business makes money and reading operating data well enough to spot where performance is slipping.
• Execution discipline: turning plans into owners and deadlines, then following up until the work gets done.
• Cross-functional fluency: knowing enough about finance and engineering to broker trade-offs between them.
• Leadership and influence: getting senior peers to commit to shared priorities, often without direct authority, which is why aspiring COOs work early to develop leadership skills beyond their own function.
• Communication: explaining operating decisions clearly to both the board and front-line teams.
  Judgment under pressure: making sound calls with incomplete information when something breaks.

How to Become a COO

Professionals reach the COO seat by many routes, usually after years of progressively broader leadership experience.

1. Earn a relevant bachelor's degree: Business, finance, engineering, and operations management are common choices, and other fields work too.
2. Build functional expertise: Develop deep experience in one area, such as operations, finance, technology, or supply chain. Operations is one of the areas expanding hiring among jobs for MBA graduates, so it offers a practical base for this step.
3. Move into progressively broader leadership roles: The usual sequence runs through director and vice president titles, sometimes with a general manager role that carries full business responsibility.
4. Develop cross-functional and financial experience: Lead initiatives that span departments and, where possible, take responsibility for a budget or a full profit and loss (P&L) statement.
5. Consider an MBA or Executive MBA: Graduate business education fills gaps a single-function career leaves, such as finance for an operations leader. If you're further along, it helps to understand what an Executive MBA is and how its schedule fits senior professionals.
6. Build an executive track record: Show that you can lead beyond one function and turn strategic priorities into measurable results.

At the Leavey School of Business, the Executive MBA is designed for experienced professionals preparing for broader leadership roles, with in-person classes about one weekend a month. Its curriculum includes a course in Operations and Supply Chains and hands-on operations simulations. In the Evening MBA, working professionals take courses such as Operations Management and Financial Management while staying in their jobs, with classes two evenings a week. Both programs are ranked #1 in Silicon Valley by U.S. News & World Report and rooted in the Jesuit tradition of ethical leadership.

Turning Strategy Into Results

The COO is the executive who connects a company's strategy to its daily work, and the exact scope depends on the company and the CEO the role supports. Across that variety, the job asks for a solid grasp of how operations run and the leadership to move people across departments toward the same priorities.

If you're building toward that kind of role, start by taking on one cross-functional project or budget you don't own today, since COOs need that breadth.

Frequently Asked Questions

Does every company need a COO?

Companies usually add a COO when operations outgrow what the CEO and department heads can manage between them, so many smaller companies run well without one.

Can a company have two COOs?

Yes, though it's uncommon. Some large companies name co-COOs to split oversight by region or business line, or during a leadership transition.

Can a COO work remotely?

Parts of the job can be done remotely, but most COOs spend regular time on-site, especially at companies with factories or warehouses.

Does a COO have to come from an operations background?

Many COOs do, such as Apple's Sabih Khan, who spent three decades in the company's operations group before becoming COO in 2025. Others arrive from finance or sales leadership and learn operations along the way.

What is the difference between a COO and a president?

The titles overlap, and many companies give both to one person. Where they're separate, the president often oversees overall business results or a major division, while the COO runs internal operations.

Can a COO become a CEO?

Yes. Some companies treat the COO seat as preparation for the top job, while others keep it as a long-term operating role.
