ISO 27001:2022 ISMS Implementation Methodology

ISO/IEC 27001:2022 implementation success depends on documentation architecture decisions made early in the ISMS design process. Poor documentation architecture — policies that do not trace to controls, controls that do not trace to evidence, evidence that cannot be located during audit — accounts for the majority of certification delays and audit findings. This methodology paper provides a prescriptive documentation architecture framework for ISO 27001 ISMS implementations, covering scope definition through Statement of Applicability development, control narrative design, and evidence framework architecture.
