What are the stages of Supply Chain maturity?

Supply Chain maturity progresses from siloed, after-the-fact visibility at Stage 1 through functional improvement, cross-functional internal optimization, and extended partner integration, to network-wide shared value creation at Stage 5. Most organizations currently operate between Stages 2 and 3, with good internal visibility but limited external synchronization. The key transitions are: from Stage 1 to 2, moving from spreadsheets to functional planning systems; from Stage 2 to 3, connecting cross-functional internal data on a shared planning model; from Stage 3 to 4, extending visibility to trading partners; and from Stage 4 to 5, creating genuine shared value across the full network with aligned data governance.
