Interim Operational Leadership & IBP Diagnostic-Led Advisory

Helping organisations stabilise performance, strengthen planning discipline and turn Integrated Business Planning into cash, control and strategic advantage.

Carter Mackenzie provides senior interim leadership and structured advisory support across Supply Chain, S&OP and Integrated Business Planning (IBP).

I work with SMEs, PE-backed businesses and larger organisations where operational performance is being undermined by weak cadence, unclear assumptions or fragmented cross-functional decision-making.

For organisations reviewing their IBP maturity, I offer a structured IBP Rapid Diagnostic — designed to quickly identify where operating rhythm, governance and accountability are fragile before further transformation investment is made.

I typically support organisations that need:

• Improved planning credibility
• Stronger cross-functional decision quality
• Reduced operational volatility
• Better working capital control
• Clear governance across Demand, Supply and Finance

When planning breaks down, performance follows.

I restore structure.

Why Carter Mackenzie

Disconnect between volume and value
Functional silos
Meeting structures without decision clarity
Repeated operational surprises

I focus on operational design, governance and behavioural discipline — ensuring planning becomes a performance driver, not an administrative exercise.

With over three decades of leadership across supply chain, operations and transformation environments, Carter Mackenzie combines strategic clarity with practical execution.
