How to run a compliance gap assessment

A gap assessment compares your current practice with a framework's requirements, to show what is missing and what to do first. It is often the first step of a compliance project.

Updated 31 October 2026

The steps

  • Choose the framework and its edition, and define the scope.
  • Break it down into requirements you can check one by one.
  • Gather what exists: documents, records, configurations.
  • Interview those who do the work.
  • Rate each requirement with a simple scale.
  • Prioritise the gaps by risk and by legal or contractual deadlines.
  • Write the action plan with owners and dates.

A rating scale

  • Met: in place, with evidence.
  • Partly met: exists but incomplete, undocumented or unproven.
  • Not met: absent.
  • Not applicable: with the reason.

What the report contains

  • The scope, the framework and the date.
  • A summary by domain.
  • Each gap: the requirement, what was seen, and what is missing.
  • The priorities and the action plan.

Gap assessment or audit?

A gap assessment prepares you and is meant to find everything. An audit gives an independent conclusion against criteria. A gap assessment gives you no certificate, but it tells you when you are ready for one.

Questions

Who should run a gap assessment?
Someone who knows the framework and can see the evidence. Internal teams can do it; an outside view helps where the team built the controls itself.
How long is a gap assessment valid?
It is a picture at one date. Repeat it after significant changes or when the framework changes.
