A Chief Operating Officer (COO) is a C-suite executive responsible for operational execution — ensuring that the company's strategy is translated into day-to-day performance across functions. The COO role is more variable than most other C-suite positions: in some companies the COO manages all operating functions and is effectively the company's number two; in others the COO is a specialist running a specific operational domain (logistics, supply chain, or production). The role is typically hired when the CEO cannot effectively manage the operational complexity of the business alone.
When a Company Needs a COO
A COO becomes necessary when: the CEO's time is dominated by operational management that would be better delegated, the company has multiple major operating functions that need senior coordination, or the organisation is scaling through a phase that requires disciplined operational execution that is not the CEO's strength.
Many technology companies do not have a COO — the CEO manages the leadership team directly, and functional VPs run their functions with autonomy. The COO hire makes sense specifically when there is more coordination and operational complexity than the CEO can manage without an operating partner.

What a COO Does
The specific scope of a COO role is defined by the CEO's strengths and gaps. A product-focused CEO may hire a COO who owns go-to-market, finance, and operations. A sales-focused CEO may hire a COO who owns product, engineering, and operations. The COO typically owns cross-functional programmes, company-wide process and efficiency, and the functions that sit below the CEO's attention threshold.
In practice, the most effective COO relationships are built around a clear division of responsibility: the CEO owns vision, strategy, and external relationships; the COO owns internal execution, operational health, and cross-functional coordination.
“The COO role is only as valuable as the clarity of what the CEO is delegating. A vague mandate produces a COO who is simultaneously overstepping and underperforming — because no one agreed on what success looks like before they started.”
COO Profiles and What to Hire For
COO candidates come from several backgrounds: operators who have built and scaled complex business functions, former management consultants or strategy executives who have moved into operating roles, or functional leaders (often in finance or operations) who have expanded into broader operational responsibility.
The intake for a COO search requires the CEO to answer clearly: what is not getting done well enough, and what would the CEO's time look like if this role succeeded? Without that specificity, the COO search produces a generic generalist hire rather than the specific operational partner the CEO actually needs.
