This practice defines the purpose and requirements of a project Scope of Work (SOW) document. The practice provides key considerations to the development of the SOW document that enables the project team to utilize it to properly plan for project execution. The designation “Project,” as delineated within this document, encompasses a spectrum of work scopes that may be as small as engagement of a third-party entity for completing a small design study or may be as large as executing complete engineering, procurement, and construction activities for a greenfield facility. This practice is not meant to provide the format, structure, or style for the development of the Scope of Work but provides considerations to customize and use as project needs dictate.
