OASIS Overview


One Acquisition Solution for Integrated Services (OASIS) is designed to address agencies' need for a full range of service requirements that integrate multiple professional service disciplines and ancillary services with the flexibility for all contract types and pricing at the task order level. Regardless of the particular area of expertise or mission space of the agency originating the requirement, OASIS may be used to support and/or improve an organization's Program Management, Management Consulting, Engineering, Scientific, Logistics, and Financial disciplines that span all life cycle phases for a total integrated solution as depicted in the OASIS Program Architecture illustration below
