There is no single “highest paid” supply chain job in all companies. In regulated industrial environments, total compensation tends to be highest for senior leadership roles with end-to-end P&L impact and significant risk accountability, such as VP/Head of Supply Chain, Chief Supply Chain Officer, or equivalent operations executive. Pay varies by industry, geography, ownership structure, and how tightly supply chain is tied to revenue and regulatory exposure. Deep technical or regulatory expertise can also command very high pay in director-level roles, especially when tied to scarce skills and high-consequence risk (e.g., aerospace, pharma, semiconductors).

In regulated manufacturing, most initiatives that touch production data, batch records, or nonconformance handling are both MES and quality projects. Treating them as belonging to just one function usually leads to gaps in requirements, traceability, validation, and ownership. The boundary depends on scope, master data, and which system is the system of record.

ISA-95 is an international standard that defines a common model and terminology for integrating business systems (like ERP) with manufacturing operations systems (like MES, SCADA, and control systems). It does not guarantee compliance or successful integration, but provides a structured way to model data, functions, and interfaces in complex, brownfield plants.
