EP 29 - Procurement & Supply Chain Leader Mark Vierling on the Three P's of Supply Chain Science

Mark Vierling, Procurement & Supply Chain Leader, makes a simple observation: while fractional COOs, CEOs, and CFOs are common, virtually no one was providing fractional Chief Procurement Officer services to companies that desperately needed them. His embedded approach, which he shares with John, differs from traditional consulting by making fractional leaders part of the client team rather than external advisors.

Drawing from automotive supply chain excellence learned at General Motors and applied across industries from manufacturing to government, Mark emphasizes why procurement must evolve from reactive cost management to proactive strategic capability. His experience implementing transformations demonstrates how the science of supply chain scales across entirely different business models and regulatory environments.

Topics discussed:

• How fractional supply chain leadership fills a gap in the executive services market via embedded CPO expertise without long-term hiring commitments.
• The transformation of procurement from reactive cost management to proactive strategic capability.
• Common ERP implementation failures caused by inadequate current-state analysis.
• AI applications in competitive sourcing for companies under $500 million, focusing on increasing competition among existing supplier bases rather than sophisticated predictive modeling.
• The three P's — people, process, and performance — as the foundation of supply chain management that scales across industries.
• Why data management and analytics will become the primary competitive differentiator in supply chain excellence.
• The evolution of entry-level procurement roles as AI automates bid processes and RFP management.
• Strategic alignment challenges between procurement teams and corporate vision, particularly in smaller companies.
• The importance of robust SIOP processes for demand and supply management.
