ISO 27001/Chapter/8.1 Operational planning and control

The organization shall plan, implement, and control processes needed to meet ISMS requirements, including criteria for processes and control of changes.

In operational terms: Operate security by process, not improvisation—run defined workflows, control changes, and keep evidence that work follows plan.

Auditors will typically look for evidence that the organization:

a. Defines and operates ISMS processes with clear criteria (inputs/outputs, responsibilities, controls).

b. Controls planned changes and reviews unintended changes to mitigate adverse impacts.

c. Keeps sufficient documented information that processes are carried out as intended.
