The organization shall continually improve the suitability, adequacy, and effectiveness of the ISMS.
Put simply: Keep raising the baseline—use evidence and lessons learned to systematically strengthen the ISMS over time.
More specifically, this requires that the organization:
a. Uses outputs from metrics, audits, incidents, and reviews to identify improvements.
b. Implements improvements across processes, controls, awareness, tooling, and governance.
c. Tracks and validates improvements as part of normal management cycles.
