C-suite

Roles and structures
What is the C-suite?

The C-suite is an organisation's most senior executive tier, made up of "chief" roles such as Chief Executive Officer, Chief Financial Officer and Chief People Officer. The name comes from the shared first letter of the titles.

Which roles make up the C-suite?

The core set is the Chief Executive Officer (CEO), Chief Financial Officer (CFO) and Chief Operating Officer (COO). Most mid-sized and large organisations add a Chief Technology Officer or Chief Information Officer (CTO or CIO), and increasingly a Chief People Officer (CPO or CHRO). Beyond that, the tier expands with the business model: a Chief Marketing, Revenue, Product or Risk Officer where those functions carry enough weight.

What is the difference between the C-suite, executives and the board?

The C-suite runs the company; the board governs it. Directors set strategy boundaries, appoint the CEO and hold management accountable, while C-suite executives own day-to-day decisions and results. "Executive" is the broader word: many organisations have executives (general managers, state directors) who sit below the C-suite tier.

Why does C-suite composition matter to HR?

Whether people decisions get made with data depends heavily on whether the person accountable for them sits at the top table. Organisations with a Chief People Officer in the C-suite treat workforce risk the way they treat financial risk: measured, reported and owned. Where HR reports two levels down, people problems tend to surface only after they have become expensive.

Common questions

Is "C-level" the same as "C-suite"?

Yes. C-level describes the individual roles, C-suite describes the group, and the two are used interchangeably.

What does the "C" stand for?

Chief. Every C-suite title starts with it, from Chief Executive Officer to Chief People Officer.
