OASIS Program Web Library

Welcome to GSA’s OASIS Program Web Library. GSA provides and maintains this resource for all federal agency personnel involved in acquiring complex professional services through the OASIS and OASIS Small Business (SB) IDIQ contracts. The website and materials are available and accessible through the Contract Administration Fees (CAF) assessed on OASIS and OASIS SB task orders.

GSA will expand the resource base as necessary to meet our customers’ needs for support in planning and acquiring professional services to meet their agencies' missions. Users can email oasis@gsa.gov to place a request for additional resource types.

Please see the OASIS reference material shown below for additional information:

DPAP Memorandum clarifying that the term “determination” as used in FAR 17.502-1 does not mean “Determination and Findings.”

The memorandum issued on July 31, 2015 by the Director, Defense Procurement and Acquisition Policy clarifies that a ‘determination and findings’ does not need to be written, rather only a ‘determination’ needs to be made.
