What you will be able to do

  • Identify recurring, costly compliance mistakes made by small businesses.
  • Explain why an empty POA&M can be a warning sign rather than reassurance.
  • Recognize the underlying pattern connecting most of the listed mistakes.
  • Apply the corrective habit for each named mistake to a real program.
  • Distinguish documentation-versus-reality gaps from genuine ambition failures.

Ten mistakes

  • Buying tools before defining scope.
  • Downloading a policy and never adapting it.
  • Claiming controls that nobody actually performs.
  • Treating an empty POA&M as a good sign.
  • Letting evidence age past the review cycle.
  • Assigning controls to departments instead of people.
  • Ignoring cloud services because 'the vendor handles it'.
  • Skipping offboarding until the quarterly review.
  • Training once and never again.
  • Writing documents nobody in the company can read.

The pattern

Almost every mistake above is a documentation-versus-reality gap. Programs fail on maintenance, not on ambition.

Key takeaways

  • Buying tools before defining scope is a common and costly first mistake in compliance programs.
  • Claiming controls that nobody actually performs undermines trust and creates real risk during assessments.
  • An empty POA&M often signals unrealistic self-assessment rather than a flawless program.
  • Assigning controls to departments instead of named individuals leads to accountability gaps.
  • Almost every recurring mistake reflects a documentation-versus-reality gap; programs typically fail on maintenance, not on ambition.
