A response structure must work under pressure, with clear leadership, decision rights, and coordination across incident management, crisis management, and recovery teams. In PP5 (Enabling Solutions), organizations embed agreed solutions by establishing response arrangements and plans that can actually be executed during disruption; that requires putting competent individuals into key leadership roles so decisions are timely, coordinated, and aligned to priorities.

Option B is therefore the correct inclusion in the process: ensure appropriate and competent individuals are assigned to leadership roles. Competence matters because leadership roles require situational assessment, escalation, communications, and resource prioritization—not just job titles.

Option A can be useful for specific dependencies (e.g., supplier coordination) but it is not a core requirement for designing the internal response structure. Option C is overly rigid: the response structure should integrate with existing management and operational structures where practical, rather than forcing wholesale reorganization. Option D (performance management) is not a prerequisite design step for response structures; it may support broader governance, but effective response depends first on clear roles, authority, and capable leadership.
