OASIS+ Support Areas

OASIS+ Pursuit and Proposal Process

Which OASIS+ domains fit your business? The answer depends on both the services you provide and the experience you can document. We review your contractual evidence against the applicable domain scorecards to identify supportable points and documentation gaps.

Our support includes:

  • Project and evidence review

  • Scorecard and domain assessment

  • Documentation gap identification

  • Teaming strategy, where appropriate

Understand what your evidence supports before investing in proposal development. If gaps remain, we help you evaluate your next steps and focus your preparation.

Proposal Development and Submission

Once your assessment establishes a pursuit strategy, we organize the required documentation and develop your OASIS+ proposal. We coordinate with your team to set responsibilities, review progress, organize your response, and submit a fully compliant proposal.

Our support includes:

  • Request for Proposal (RFP) analysis and requirement mapping

  • Contributor coordination

  • Project documentation and narratives

  • Editing and quality reviews

  • Compliance verification

  • OASIS+ Submission Portal support

  • Responses to post-submission government questions

Get experienced support through submission and the evaluation process.

OASIS+ Domain Additions

Already hold an OASIS+ contract? Your documented experience may support additional domains and expand the service areas in which you can compete.

Global Services helps you assess the applicable domain requirements, review potential scorecard points, organize supporting evidence, and prepare the required submission. We scope domain additions as a separate project based on your qualifications and the support your team needs.
