A statement of work (SOW) is a formal document that defines the entire scope of work involved for a vendor
and clarifies deliverables, costs, and timeline1. It serves as a contractual agreement between a vendor and a
client, providing a comprehensive description of the work to be performed2. A reason to use a SOW on a
project is to ensure the team stays within the scope of the contract, as it outlines what the team will and won't
do on a project, saving from painful client negotiations and protecting the timeline and the bottom
line3. References = CompTIA Project+ PK0-005 Certification Study Guide, Chapter 3: Initiating Projects Part
