From Point-in-Time to Continuous: How HHS PMOs Are Modernizing the ATO in 2026
For the Program Management Office and ISSO in April 2026, the old compliance model is no longer viable. Static, point-in-time documentation packages take months to assemble, and by the time they are signed, the underlying environment has drifted enough that the evidence is already partially obsolete. The result is what practitioners call Documentation Lag: a false sense of security that leaves agencies exposed to unmanaged technical risk between audit cycles. The 2026 federal landscape has formalized this concern into hard requirements. At Avalon, we help HHS leaders move from reactive documentation to a Continuous Evidence model, where the Authority to Operate is maintained as a live, verifiable signal rather than a periodic deliverable. This shift protects the mission's fiscal and operational integrity while turning compliance posture into a measurable source selection differentiator.
