At which level in the ISA 62443 Reference Model is Business Planning and Logistics found?

Business Planning and Logistics is situated at Level 4 of the ISA 62443 Reference Model, which focuses on organization-wide management and business planning activities. This level encompasses the strategic and administrative aspects of an organization, looking at how business objectives align with cybersecurity and operational requirements.

At Level 4, the emphasis is on overarching business processes, risk management, and the integration of business planning with operational functions, which includes logistics. This is vital for ensuring that security measures are part of the organization's strategic goals and that resources are allocated effectively to mitigate risks while achieving business objectives.

In contrast, the other levels pertain to different aspects of the automation and control systems. Level 0 deals with physical processes, Level 1 is focused on control processes, and Level 2 is about monitoring and control applications, all of which are more operational and technical in nature rather than strategic business functions.
