Federal Agency TOGAF ADM Implementation

Client Context

A civilian federal agency with eight thousand staff implemented TOGAF ADM to align CPIC investments with mission outcomes and strengthen ATO architecture packages. Larkinized worked with the EA lead, CIO council, and authorizing officials on a two-year program.

Challenge

Segment architectures were outdated; project charters lacked architecture sections examiners flagged. Contractors produced inconsistent viewpoints; internal EA team was three FTE overwhelmed by review volume.

Approach

We tailored ADM phases to annual POM cycles—Architecture Vision each spring, gap analysis each fall. Templates linked investments to FEAF viewpoints. Train-the-trainer expanded certified internal architects from three to twelve. Quick win: standardized data exchange reference for three high-traffic mission systems.

Architecture Decisions

Mandatory architecture content in CPIC gates above two million dollars; ArchiMate subset for interoperability; Sparx repository with baselines for ATO evidence. SaaS allowed only on FedRAMP inherited boundary list.

Outcomes

One hundred percent of major investments linked to architecture artifacts within eighteen months. ATO preparation time dropped twenty-five percent for pilot systems. EA team staffing plan approved with clear roles—not contractor dependency.

Lessons Learned

Align ADM cadence to federal budget rhythms or it becomes shelf-ware. Authorizing officials must see architecture in packages they already read—not separate portals they ignore.
