Problem Solved
Engineers accommodate informal client scope changes via Slack or verbal requests without commercial review, inflating delivery costs, causing milestone delays, and sparking bitter billing disputes.
When to Use
- •Evaluating any client request to add, remove, or modify functional requirements, integrations, or non-functional targets
- •Assessing the schedule and cost impact of unforeseen technical discoveries (e.g. undocumented legacy database schemas)
- •Executing legally binding amendments to Statements of Work with adjusted fees and billing milestones
When NOT to Use
- •For internal zero-cost developer bug fixes and defect resolution (use TPL-QAV-010)
- •For standard IT infrastructure change management and maintenance windows (use TPL-SVC-006)

Frequently Asked Questions
Why must work NEVER commence before a Change Request is formally signed by the client?
Commencing work on informal promises ("verbal approval" or email nods) is the single most common cause of consulting write-offs. If client executive sponsors change or budget freezes occur, the vendor has zero legal standing to invoice for completed work without an executed, binding contract variation.
How does this pack handle the schedule impact of a change on existing delivery commitments?
The pack mandates a Schedule Impact Analysis that maps new requirements against the project critical path. It requires explicit adjustment of intermediate UAT windows, final go-live dates, and client review periods, legally relieving the delivery team from liquidated damages for original deadline dates.
What is the role of a Change Freeze window in enterprise delivery contracts?
A Change Freeze window locks all functional requirements typically 30 days prior to major User Acceptance Testing (UAT) or production go-live. It ensures stability, eliminates regression defects, and mandates that any further change proposals are queued for post-launch release phases.
