Supply Chain Strategy and Integrated Planning
Strategic fit and the planning stack
Supply chain strategy begins with strategic fit: the chain's design must match the product's competitive priorities (cost, speed, variety, responsiveness). Segment by demand and supply characteristics, not just product family. Know SCOR's level-1 processes - Plan, Source, Make, Deliver, Return, Enable - and that Level 1 defines scope, Level 2 configuration, Level 3 process detail.
Core concepts: the push–pull boundary and the decoupling/postponement point; lean (efficiency under stable demand) versus agile (responsiveness under volatile demand); and the bullwhip effect, driven by forecast updating, order batching, price promotions, rationing/shortage gaming, and lead-time variation. Integrated planning links demand planning → S&OP/IBP → master production schedule → capacity and inventory deployment. S&OP is a monthly cross-functional cycle (product, demand, supply, reconciliation, executive sign-off); IBP adds financial and strategic alignment.
Traps: equating S&OP with forecasting; assuming lean is always superior; choosing push or pull without locating the decoupling point; confusing service-level targets with forecast accuracy; and treating the bullwhip effect as purely a forecasting problem when batching and promotions often dominate.
Rule of thumb - strategic fit test: if demand is unpredictable and total lead time exceeds customer tolerance, move the decoupling point downstream and hold postponement inventory; if demand is stable and volume high, centralize and drive efficiency.
Worked example: A fashion retailer with six-week demand windows and high markdown risk should not chase lowest unit cost via a 120-day ocean-only pipeline unless it applies postponement (late dye/cut) or a fast replenishment lane. Compare total cost of each design, not freight rate alone.
