PSC DF01 is the CIO front-office code. The manual scopes it as support for IT management across three named areas: enterprise architecture, covering business, information, application, and technical architecture work that drives standardization and integration; IT financial management, covering planning, budgeting, spend management, chargeback, and the costing of IT products and services; and IT strategy and planning, described as senior professional and administrative support facilitating centralized IT strategy. FY2025 obligations totalled $4.6 billion.
Advisory work, engineering registrations
Computer Systems Design Services (541512) took $2.2 billion, Other Computer Related Services (541519) took $1.42 billion, then custom programming 541511 at $380 million, Computer Facilities Management Services (541513) at $244 million, and engineering services 541330 at $140 million. Nothing here is a management consulting registration, even though the work described is planning, budgeting, and architecture, not build.
The two-code question, answered once
A PSC labels the requirement and a NAICS code labels the contractor, and they are chosen by different people at different times.
The real risk with DF01 is miscoding, in both directions. IT strategy work also lands in R408 and R425 when a program office buys it, and DF01 requirements sometimes get filed under DA01 because a systems integrator is bidding. If you sell IT advisory services, watch DF01, DF10, R408, and R425 together.

Frequently Asked
PSC DF01 questions, answered.
What does PSC DF01 cover?
IT management support delivered as labor: enterprise architecture, IT financial management including budgeting and chargeback, and centralized IT strategy and planning support.
What NAICS codes win DF01 work?
Computer Systems Design Services (541512) at $2.2 billion and Other Computer Related Services (541519) at $1.42 billion take the bulk of FY2025 obligations, with 541511 at $380 million and Computer Facilities Management Services (541513) at $244 million.
Is enterprise architecture DF01 or R425?
Enterprise architecture for the IT enterprise is DF01 by name. Systems engineering supporting an acquisition program office is R425. Agencies split this inconsistently, so watching only one code misses recompetes.
What is DF10?
DF10 is the same scope delivered as a service or subscription rather than as labor hours. Together the two codes carried about $5.8 billion in FY2025, so treating them as one market is the only sensible approach.
