Common Mistakes to Avoid
These mistakes repeatedly slow evidence readiness and create retest cycles across FISMA engagements.
Starting without a continuous monitoring plan that ties controls to evidence
Organizations that skip evidence-driven continuous monitoring design often struggle when artifacts must remain consistent through assessments and remediation cycles, which is why Accenture Federal Services and Booz Allen Hamilton emphasize continuous monitoring planning tied to NIST coverage and RMF artifacts.
Assuming POA&M remediation will happen without an integrated control testing evidence loop
When POA&M workflows are treated as separate from control testing evidence, remediation progress becomes harder to validate, which is why Leidos integrates POA&M remediation support with continuous monitoring and control testing evidence.
Choosing a provider that expects internal evidence readiness without accounting for evidence collection constraints
Engagements can require strong client ownership for timely evidence, which affects SAIC, Leidos, NCC Group, and Protiviti when system documentation and control details are delayed.
Over-scoping governance without a plan for stakeholder coordination and documentation fragmentation
Large program structures can feel rigid for small system teams at Accenture Federal Services and engagements can require heavy stakeholder availability for evidence collection at Booz Allen Hamilton. Control documentation fragmentation can extend execution time at Protiviti and can delay evidence deliverables at Tetra Tech when review turnaround is slow.
