Procurement & supply chain transformation advisory
Restore control
before drift
becomes structural.
Helping leaders restore control when strategy, suppliers, governance and execution drift apart.
Move your cursor over the network: links pull back into place.

What drift looks like
Programmes rarely fail in one moment. They drift.
Ownership blurs, suppliers multiply, data stops matching and workarounds become normal. Each month the gap between the plan and what is actually delivered gets wider and harder to close.
An early, independent diagnostic turns the line back before the drift becomes structural.
Check your own driftWhere the work happens
From the warehouse floor to the boardroom.
Control is won or lost in real operations: at the port, on the line, in the aisle and around the leadership table.

Meet Mark
“The problem everyone is talking about is not always the problem that actually needs solving.”
I’ve bought. I’ve sold. I’ve negotiated. I’ve run businesses, carried a P&L and led teams. And I’ve been the consultant telling someone else what I think they should do. That last one matters. Advice looks very different when you’ve been the person who has to make it work on Monday morning.
