OASIS+ Phase II - GDI Consulting

OASIS+ Phase II: Our Proven Approach

With GSA’s newest announcement positioning OASIS+ as the government’s central platform for consolidated, interoperable professional-services procurement, contractors entering Phase II face a more complex and scrutinized environment than ever before. This is where OASIS+ Phase II Support Services become essential. Our Phase I clients achieved a 99% overall win rate (97 of 98 awards), driven by precise self-scoring strategy, evidence-backed documentation, and disciplined NAICS and Domain alignment.

As OASIS+ expands to absorb more categories and agency portfolios, we apply those same principles to Phase II. Our OASIS+ Phase II Support Services translate Phase I lessons into a targeted, compliance-driven framework: interpreting updated requirements reflecting procurement consolidation, building defensible substantiation matrices, curating project evidence and corporate systems proofs, aligning labor structures and pricing rationale, and producing a submission that withstands heightened evaluation scrutiny in the new OASIS+ landscape.

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

OASIS+ is the government’s next-generation Best-in-Class IDIQ for acquiring integrated non-IT professional services. GSA’s latest announcement underscores its expanded role as a single, enterprise-ready contracting solution that replaces fragmented vehicles like OASIS, BMO, and HCaTS. As agencies transition work into OASIS+, the vehicle becomes the governmentwide channel for complex mission support across technical, management, and professional disciplines.

Phase II builds directly on this consolidation. While Phase I awarded eight initial Domains, Phase II introduces additional service areas that enable agencies to shift more mission portfolios into the unified OASIS+ framework. With cross-government interoperability and standardized evaluation criteria now central to GSA’s acquisition strategy, contractors need OASIS+ Phase II Support Services that ensure accurate scoring, compliant structure, and clear Domain alignment under the expanded model.

Phase II Add‑On Domains

  • Business Administration – Strategy development, enterprise process optimization, and integrated program management supporting cross-agency operations.
  • Financial Services – Budget, audit, compliance, and financial risk expertise that accelerates federal financial modernization.
  • Marketing & PR – Strategic outreach, research, communications, and engagement capabilities aligned with governmentwide messaging needs.
  • Social Services – Health, community, and social-impact program support as these portfolios migrate into OASIS+.
  • Human Capital Services – Workforce analytics, talent development, and HR modernization enabling agencies to transition legacy human-capital initiatives into OASIS+.

Eligibility at a Glance

Before competing under Phase II, contractors must demonstrate that they meet essential pre-qualification thresholds tied to their chosen Domains. OASIS+ Phase II Support Services begin with confirming your readiness in these areas to prevent preventable score loss later in the process.

  • 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 validates each requirement early, ensuring that your scoring model remains intact throughout proposal development.
