OSD achieves best value by using Strategic Sourcing Services Teams (SSST) to ensure that customer needs are met by involving those customers directly in the entire procurement process. Any purchasing entity, including departments conducting individual or joint procurements, can use the SSST approach.

OSD SSST's are composed of members drawn from departments and eligible public entities that have an interest or expertise in particular commodity and service categories. SSSTs are led by OSD's professional contract managers, known as Strategic Sourcing Services Leads (SSSLs).

SSSTs focus significant attention on establishing quality statewide contracts that meet customers' needs for commodities and services. Together, they decide how most large procurements will be accomplished and perform activities throughout the life-cycle of the procurement, from identification of need through performance monitoring and assessment.
