In pay-setting, the firm that measures the market also makes it.

In compensation consulting, the firm that measures the market also makes it.

A comp study does not observe an external market the way an appraiser observes home sales. Its recommendations become the pay structure that the next jurisdiction benchmarks against. When one firm has built hundreds of plans across dozens of states, the prevailing market a new study measures is substantially that firm's own prior work, echoed back. Concentration converts an independent measurement into a self-referential loop. This is a property of market structure, not a comment on any firm's competence.

Evergreen Solutions reports public-sector clients in 47 states and hundreds of compensation and classification plans (consultevergreen.com).

Salary benchmarking is an estimation problem, and diversity is half the answer.

Scott Page's Diversity Prediction Theorem is exact: a group's collective error equals the average individual error minus the diversity of the individual predictions. Diversity and accuracy contribute equally. A field served by methodologically diverse firms produces a more accurate aggregate of public pay-setting than a monoculture of individually excellent ones, because independent methods cancel one another's blind spots. A single method, however good, cannot correct its own.

One lens applied everywhere propagates the same errors everywhere.

A single dominant point-factor methodology applied across hundreds of jurisdictions carries the same systematic assumptions into each one. Where that method quietly under-weights a job family, it under-weights it everywhere it is used. The roles most often caught in that gap are the ones that do not fit a clean template: emergency dispatchers, social services, skilled trades, and front-line care work. A second, independent method re-tests what the first one assumes.

Methodological monoculture is the mechanism the Diversity Prediction Theorem warns against.

Regulators have already studied what happens when a few firms set the standard.

The audit market is the clearest precedent. Reviewing Big Four dominance, regulators flag a consistent list: less choice, less innovation, higher fees, eroded independence and professional skepticism, and systemic fragility when one firm's error or failure spreads across everyone it served. When Arthur Andersen collapsed, roughly 1,300 companies scrambled at once. Public pay-setting, which shapes the budgets of entire communities, deserves the same scrutiny of concentration that financial reporting receives.

The firm doing its 400th templated study has little reason to change it.

Method innovation in this field, AI-assisted analysis reconciled by credentialed experts, transparent reconciliation logs, and live decision tools like this portal, tends to arrive through challengers rather than through the incumbent protecting a high-volume book of business. National research on procurement concentration finds the same pattern across government contracting: fewer firms means higher costs and less innovation, and the small, nimble entrants are where commercial innovation reaches the public sector.

A study about fairness benefits from people who understand what fairness costs.

Classification and compensation is, at bottom, a fairness exercise: paying the work what the work is worth, consistently, across people. A field served by homogeneous teams tends to under-weight the dimensions it does not experience. Bringing the lived perspective that pay equity exists to protect is not a diversity checkbox here; it is subject-matter expertise applied to the actual subject. House Strategies Group is an SBA 8(a)-certified, minority-owned firm.

A fresh voice re-examines first principles instead of grading its own homework.

When a single firm holds a jurisdiction's compensation work across many cycles, each new study tends to validate the last. The reference point stops being the outside market and becomes the firm's own prior recommendation. An independent study that returns to first principles is not a risk to continuity; it is a governance safeguard, the same reason public bodies rotate auditors and re-compete contracts.
