SOW Clarity and Scope Control Starter Kit

A simple kit to define scope clearly so vendors can't 'interpret' it—and you can enforce pricing, performance, and invoice standards.

Run the OperationStarter Kit20 min

Primary outcomes:

•Cost reduction: fewer change orders, fewer disputes, cleaner invoices, less rework
•Risk mitigation: fewer operational failures from "we assumed you meant…"
•Carbon impact (optional): you can embed data requirements, but scope control is the main goal

Beginner truth: If scope isn't written in plain English, it isn't enforceable.

What you'll build

a clear Included / Excluded scope
unit definitions (what a 'visit' means, what a 'job' means)
service windows and response expectations
acceptance criteria and evidence requirements
change order triggers (hard rules)
invoice minimum standards tied to the scope
