When a customer pushes for an unfunded change or asks to ship before readiness, the fastest way to lose control is to treat it as a personal confrontation. Effective project leaders do not do that.

Instead, the conversation is grounded in facts, contracts, and risk:

• What are the agreed acceptance criteria?
  Start with the contract, statement of work, or baseline requirements that define “done.” Confirm that the criteria are objective, testable, and already approved, not newly interpreted under pressure. Use documented artifacts such as acceptance test plans or a requirements traceability matrix to anchor the discussion. If criteria are unclear or outdated, pause delivery decisions until they are formally clarified.
• What is complete and what is not?
  Use evidence, not percentages, to show status such as passed tests, signed deliverables, and verified artifacts. Clearly separate completed work from work that is partially complete, unverified, or not started. Avoid optimistic language, as unfinished work is still unfinished regardless of effort spent. This clarity prevents false confidence and forces honest trade discussions.
• What risks are introduced if we proceed anyway?
  Describe downstream impacts to quality, compliance, safety, or operations, not just schedule risk. Identify who absorbs the risk if the decision is made to proceed, such as the customer, operations, regulators, or support teams. Distinguish between reversible risks and those that create permanent exposure. Framing risk ownership often clarifies decisions faster than arguing timelines.

This approach removes emotion from the equation and replaces it with shared reality.

Unfunded scope and premature delivery do not just threaten schedules. They erode trust. When customers see decisions handled consistently and professionally, trust increases even when the answer is not what they hoped for.

Formal change control is not bureaucracy for its own sake. It is how organizations:

• Preserve mission assurance.
  Mission assurance is protected by defining non-negotiable readiness criteria tied to safety, reliability, and operational effectiveness, and refusing to trade them informally under schedule pressure. Verification results, operational scenarios, and failure modes make readiness risks explicit. Any proposed trade that weakens mission outcomes is escalated with documented impacts to the appropriate decision authority, such as program sponsors, executive owners, governing boards, or senior leadership accountable for accepting mission risk.
• Maintain compliance.
  Compliance is maintained through discipline, not intent. Decisions are anchored to regulatory, contractual, and policy requirements that cannot be waived without formal authority. Deviations are documented, approved, and traceable to an accountable owner. Temporary workarounds that create permanent audit exposure are avoided.
• Protect downstream teams and customers from hidden risk.
  Risks that would otherwise surface in operations or support are made visible early. Technical or schedule shortcuts are translated into operational consequences. If a trade is accepted, risk ownership is explicit. Hidden risk becomes manageable only when it is exposed.
