Milestone-Based Control
Definition
Milestone-Based Control is a governance model where deal progression is anchored to verifiable milestones rather than subjective stage labels. Each milestone represents a concrete, evidence-backed event that confirms the deal has genuinely advanced.
Milestone Types
Discovery Milestones
Confirm that the problem, stakeholders, and decision process have been identified and documented. Evidence includes meeting notes, stakeholder maps, and recorded problem statements.
Validation Milestones
Confirm that the proposed solution has been evaluated against the buyer's requirements. Evidence includes technical assessments, proof-of-concept results, and stakeholder feedback.
Commitment Milestones
Confirm that the buyer has made a concrete commitment to proceed. Evidence includes signed letters of intent, budget approvals, and procurement timelines.
Delivery Milestones
Confirm that agreed deliverables have been completed. Evidence includes signed contracts, onboarding confirmations, and acceptance documentation.
Control Mechanisms
Milestone Gates
A milestone gate prevents a deal from being marked as progressed until the required evidence is attached. This eliminates phantom pipeline progression.
Time Windows
Each milestone has an expected completion window. Exceeding this window without completion triggers a drift alert.
Ownership Assignment
Every milestone has a named owner — the individual accountable for driving that milestone to completion.
Evidence Requirements
Each milestone specifies the type and minimum quantity of evidence required for completion. Milestones without evidence remain open regardless of narrative claims.
Comparison with Stage-Gate Models
| Aspect | Traditional Stage-Gate | Milestone-Based Control |
|---|---|---|
| Granularity | Broad stages (e.g., "Negotiation") | Specific events (e.g., "Budget approval received") |
| Evidence | Optional | Required |
| Ownership | Deal-level | Milestone-level |
| Drift detection | Not built-in | Inherent via time windows |
| Reversibility | Stages rarely reversed | Milestones can be invalidated |
