The parts that touch your schedule.

Flow-down is yours

The requirement passes to subcontractors and suppliers who will process, store or transmit Federal Contract Information or Controlled Unclassified Information on their own systems. Commercial off-the-shelf suppliers are excluded. The practical consequence is that your supplier list has to be sorted by what information each one actually touches, and that sort is usually wrong the first time — the question is not what a supplier does, it is what data reaches their systems to do it.

Scoping is a schedule decision

Boundary decisions set the size of everything downstream: how many systems get hardened, how much evidence is maintained, how long the assessment takes. Made late, they invalidate work already done. The sequence that holds is discovery, then gap assessment, then remediation, then documentation — and the most common expensive mistake in this programme is buying tooling before anyone has decided what is in scope.

The 180-day window is a real date

Where a Plan of Action and Milestones supports a conditional status, it must be closed out and reassessed within 180 days of the status date, and only certain requirements are eligible to be on one in the first place. Treat that as a milestone with a dependency chain behind it rather than as an administrative deadline, because the remediation it covers is engineering work with lead times.

Between assessments

A certification is valid for three years and the affirmation is annual, so the programme has no quiet period. Configuration drifts, staff change, and a score that was true at assessment stops being true without anyone doing anything wrong. The cadence that keeps it honest — evidence refresh, log review, access recertification — belongs on the schedule like any other recurring obligation.
