SHORT ANSWER

Supply planning converts unconstrained demand into a feasible plan using inventory, materials, capacity, lead times, and operating constraints.

01

Purpose

The job is to determine what can be fulfilled, when, from which source, and with which tradeoffs.

02

Core inputs

Demand, on hand, open supply, BOM, lead times, capacity, yields, calendars, policies, priorities, costs, and constraints.

03

Core outputs

A feasible production, procurement, transfer, and inventory plan plus exceptions requiring a decision.

04

Constraint hierarchy

Separate hard constraints from policies and preferences. Model material, labor, equipment, logistics, cash, regulatory, and customer constraints explicitly.

05

Cadence and horizons

Strategic, tactical, and execution horizons need different detail. Freeze zones and review cadence determine which actions remain feasible.

06

Exception management

Good planning focuses attention where risk, value, service, and decision lead time intersect, not on reviewing every SKU equally.
