HR Was the Right Size. The Shape Was the Question.

We started with the ruler, not the data. A benchmark is only as good as its definitions, so we built one HR taxonomy before counting anyone: 4 domains, from leadership and strategy to operations and services, 12 practices and 39 role types. Every profile, at the client and at each peer, was classified against the same list. Job titles differ from firm to firm; the taxonomy does not.

Then the panel. 11 institutions headquartered in the same country, from about 700 to more than 7,500 employees, covering some 34,000 employees and 666 HR professionals between them. Peers were chosen for the market they share with the client, not for the convenience of their data. All were read from the same public source, so every firm carries the same bias, and the client’s own count was checked against its internal HR headcount before any comparison.

Then 2 measures at every level. Employees served per HR professional answers the size question. Each practice’s share of the firm’s own HR team answers the shape question, and corrects for company size. Both were set out as ranges, through the quartiles, for the whole function, each domain and each practice. Small HR teams swing hard in percentages, so extreme values were flagged, not quoted.

The answer came in 2 parts. On size, the firm sat close to the peer median: no case for adding or cutting heads. On shape, it stood apart: most of its HR team sat in expertise and business partnering, operations was thinner than at peers, and 3 practices that peers staff had no dedicated role. Each gap was then read against the firm’s business and HR priorities, so every shift had a reason, and we pointed to where to rebalance first: operations, and the missing strategy and governance capacity. Same envelope, different mix.
