ISO 37001:2016 5.3.1: 5.3.1 Roles and responsibilities
Top management carries overall responsibility for putting the system in place and complying with it, as set out in 5.1.2, and makes sure responsibilities and authorities for the relevant roles are assigned and communicated at all levels. Each manager must require that the system is applied and followed in their department or function, and the governing body, top management and everyone else must understand, follow and apply the requirements that bear on their own role.
This control maps to 27 controls across 24 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
