Leverage Erosion
The buyer's ability to enforce contract terms degrades over time.
The buyer's ability to enforce contract terms degrades over time as dependencies deepen, alternatives narrow, and the people managing the contract don't understand it.
Recognition signals
- Milestone payments are the only enforcement mechanism. The contract has penalty clauses, remediation provisions, and performance frameworks — but the only lever anyone uses is withholding payment. Everything else sits unused because nobody knows how to invoke it.
- Variation mechanisms aren't understood by the people negotiating scope changes. The PM agrees to scope adjustments without knowing the commercial implications. The contract allows variations, but the variation process requires commercial expertise the project doesn't have.
- Contract knowledge is concentrated in one person. When they leave, the commercial capability walks out the door. The replacement inherits a contract they haven't read in a context they don't understand.
- Legal counsel wasn't briefed on the engagement until crisis. The first time the legal team sees the contract is when something goes wrong. They inherit a dispute about a document they've never read.
- "We've never actually used the penalty clause." The enforcement mechanisms exist on paper but have never been exercised. The vendor knows this. Every month they go unused, the implicit message is that they won't be used.
Structural cause
Why this happens
Commercial leverage requires competency, not just authority. When the people managing the contract don't understand the contract, and the people who do aren't in the room, the vendor's position strengthens by default.
Leverage erodes through a series of small, rational decisions. Each uninformed concession — a scope variation without commercial review, a milestone approved without quality assessment, a penalty clause not invoked because "it would damage the relationship" — ratchets leverage toward the vendor.
The erosion is invisible because each individual concession looks reasonable. It's only when you map the cumulative effect — the scope that's expanded without price adjustment, the milestones that were paid without deliverable assessment, the SLAs that were never measured — that the pattern becomes clear.
Risk mapping
| Risk | Description |
|---|---|
| CO1 | Leverage gap — buyer's enforcement position weakens over time |
| CO2 | Competency gap (commercial) — variation mechanisms used without commercial expertise |
| G7 | Competency gap (contract) — contract managed by people who don't understand it |
| K5 | Key person risk — commercial knowledge concentrated in one person |
Self-assessment
When to worry
- You couldn't name a specific contract clause you'd enforce if the vendor underperformed
- Variation mechanisms aren't understood by the people negotiating scope changes
- Contract knowledge is concentrated in one person
- Legal counsel hasn't been briefed on the engagement
When you're OK
- Contract enforcement mechanisms have been exercised at least once
- Variation requests require commercial review before agreement
- Legal counsel was briefed within the first month
- Multiple people can interpret and apply contract terms
