Strong staffing reviews for speed and scale. Seen as a vendor, not a partner — a distinction CSC should lean into hard in its co-sourcing positioning.	Co-Sourcing only Relevant only for co-sourcing and IT staff aug budgets. CSC's advisor-led model is a clear differentiator.

The strategic problem RSM, Baker Tilly, Crowe, and Plante Moran all tell a story that sounds like CSC's. Solution set overlap is high enough that a prospect could choose any of them. CSC's differentiation must be specific and repeatable — not just "we're more personal."

Where CSC has an opening None of the Tier 1 competitors combine accounting advisory breadth with strong cybersecurity, SOC, and AI consulting the way CSC is positioned to. That combination — plus regional presence — is not easily replicated by any firm in this matrix.
