Supply Chain Planning Manager

A supply chain planning manager runs the planning function — demand forecasting, sales and operations planning (S&OP), inventory target-setting, and capacity allocation across plants and warehouses. The work is analytical at its core: translating demand signals into supply requirements, identifying capacity constraints before they become crises, and reconciling the different views that sales, operations, and finance bring to the plan. But it's also deeply political — getting three functions with different incentives to agree on a single operating number is rarely a pure analytical problem.

The S&OP process is the recurring heartbeat of the role. A well-run S&OP brings sales forecasts, operations capacity, and finance targets into alignment monthly, creating a plan that everyone owns. A poorly-run S&OP produces a document that no one believes but everyone works around. Planning managers who can facilitate a genuine alignment conversation — not just host a meeting where conflicting plans sit in the same room — create organizational value that goes beyond any individual forecast call.

Forecast accuracy is the metric that gets the most scrutiny, but it's also the most misunderstood. No forecast is accurate; the question is whether it's directionally useful and whether the planning process responds to signal changes quickly enough. Planning managers who spend their time defending forecast accuracy instead of improving forecast process miss the more valuable work. Those who build systems for rapid demand signal integration and fast inventory response are the ones whose operations perform well through volatility.
