what is a statement of work or performance work statement?

A Statement of Work (SOW) or Performance Work Statement (PWS) is a formal document that outlines the specific goals, deliverables, tasks, and timelines for a project or contract. It details the scope of work to be performed, including performance standards and requirements, to ensure all parties have a clear understanding of expectations. The SOW/PWS serves as a foundation for project planning and execution, providing a basis for measurement and evaluation of performance.
