NOTE: Generally, ordering activities use these procedures when ordering services priced at hourly rates as established by Schedule contracts. The applicable services will be identified in the GSA Schedules and the contractor’s pricelist.
An SOW, or if performance-based, a Performance Work Statement (PWS) or Statement of Objectives (SOO), is necessary when acquiring a service that does not rely on the Schedule contractor’s commercial description to define the requirements (e.g., program management services). Using this example, the SOW would describe the requirements for a management process improvement program that must be met – the tasks, deliverables and specific delivery dates.
To the maximum extent practicable, agency requirements shall be performance-based (refer to FAR Subpart 37.6, Performance-Based Acquisition).
