What is operative IT vendor management?

Operative IT vendor management is the discipline that runs after the contract is signed. It is a governance framework with seven core capabilities (Performance Management, Financial Management, Demand and Change, Escalation, Reporting, Roles and Responsibilities, Tools) that close the post-signature value gap.

How long does it take to build a vendor management operating model?

12 months on a four-phase path: Assessment (weeks 1-4), Design (weeks 4-10), Build and Pilot (weeks 10-26), Scale and Embed (weeks 26-52). Twelve months produces a piloted operating model and an embedded capability, in that order.

Operative IT Vendor Management.

Q: How much value do organizations lose after signing a contract?

11% of contract value on average, according to WorldCC and Ironclad 2024 research. For an enterprise with $500M in annual contracted spend, that is up to $55M every year, lost through unvalidated invoices, scope creep, missed renewal triggers, and post-signature contract amendments.

Most organizations lose 11% of contract value after signature. For an enterprise with $500M in annual contracted spend, that is up to $55M every year. The cause is not bad negotiation. It is the absence of an operating model for what happens after the contract is signed.

A governance framework, the seven core capabilities, and a 12-month path to build one.
