What Is OASIS+, and What’s New in Phase II?

The General Services Administration’s OASIS+ is a Best‑in‑Class, multi‑agency IDIQ that consolidates professional, technical, and non‑IT service procurements once scattered across OASIS, BMO, and HCaTS. Phase I launched eight core Domains; Phase II adds five more, opening billions in new federal spending for agile contractors.

Phase II Add‑On Domains

  • Business Administration – Corporate strategy, process improvement, and program integration services.
  • Financial Services – Budgeting, auditing, risk, and financial management support.
  • Marketing & PR – Strategic communications, market research, and outreach campaigns.
  • Social Services – Community, health, and welfare program support and case management.
  • Human Capital Services – Workforce planning, training, and HR operations modernization.

Eligibility at a Glance

Before bidding, contractors must demonstrate that they meet critical qualifications—project experience, federal past performance, approved systems, and key certifications—aligned to their chosen Domains. This section outlines those core eligibility criteria.

  • Qualifying Project Experience – Recent, relevant projects aligned to each target Domain.

  • Federal Experience – Positive CPARS or equivalent performance with U.S. agencies.

  • Government‑Approved Systems & Rates – DCAA‑accepted accounting and forward‑pricing rates enabling cost‑type work.

  • Relevant Certifications – ISO, CMMI, EVMS, or similar credentials that add scorecard points.

GDI Consulting confirms each requirement up front—preventing late‑cycle score loss.
