Demand planners

From chasing forecast accuracy to shaping demand posture and reviewing material commitments.

Before

Forecast accuracy is the KPI. Forecast variance is the planner's defense at S&OP.

After

Demand-shaping posture is the work. Material customer commitments are the queue.

The demand planner's old reality is a forecast they didn't shape and can't defend. Top-down meets bottom-up; the reconciliation eats the week. Forecast accuracy gets measured at month-end, attributed to the planner, and used to grade the planner — but the four levers that actually move demand (pricing, promo, substitution, channel mix) sit with Marketing, Sales, and Operations. The planner owns the metric without owning the means.

The new reality flips that. Demand is a learned distribution per SKU-location, sampled jointly with correlated drivers. The planner's job stops being to predict the point estimate and starts being to shape the posture against the realistic distribution. Which SKUs are forecastable in the strict sense? Which need a substitution policy because their demand variability dwarfs the substitute's lift? Which respond to promo at enough margin to justify the operational cost? Which have asymmetric cost-of-bias that warrant conservative cover? Those are the planner's questions.

The morning queue is the material customer commitments — large pull-ins, contractual SLA risks, named-customer allocation conflicts under scarcity. The afternoon is posture-shaping work — tuning the Demand sub-policy in collaboration with Marketing on promo, with Sales on customer priority, with Operations on substitution acceptability. The planner stops being the bottleneck through which everyone else pushes commercial decisions. The Demand sub-policy becomes the shared artifact those teams configure together; the demand planner governs the posture that integrates them.

VYAN's answer

The work stops being to predict the future. It starts being to shape the posture against the realistic distribution of futures.
