0–39: Low maturity
Procurement here is processing transactions, not managing exposure. The organisation is choosing suppliers on the strength of their sales process rather than your evaluation process, and the cost of that shows up later, in delivery, dependency and renewals negotiated from weakness.
40–59: Developing maturity
The function has real process on the biggest deals and thin coverage everywhere else. The exposure is the middle tier: contracts too small for scrutiny and too large to fail without damage, signed on vendor paper with nobody tracking the obligations.
60–79: Moderate maturity
This is a function the business takes seriously: aligned early, commercially literate, watching its contracts. The residual weakness in most functions at this level is the feedback loop: delivery experience and independent challenge still depend on individuals rather than the system.
80–100: Stronger maturity
These answers describe procurement operating as a genuine control and value function. The remaining risk is concentration of a different kind: mature functions develop house views (preferred vendors, trusted integrators, settled category doctrine) and house views go stale without anyone noticing.
