Strategic Supply Chain Management
The Strategic Supply Chain Management domain tests whether you can connect supply chain design to competitive strategy: how the network of suppliers, internal operations and customers is configured, measured, de-risked and improved to deliver organisational goals. Questions typically ask you to diagnose a supply chain problem and justify interventions using recognised models, not merely to describe those models.
Core rules and concepts
- Strategy alignment first. Cost-leadership, differentiation and focus strategies demand different supply chains. Fisher's framework pairs functional products (stable demand) with efficient chains, and innovative products (volatile demand) with responsive chains. Responsiveness costs money, so justify it against the cost of lost sales or service failure.
- SCOR organises processes as Plan, Source, Make, Deliver, Return and Enable, and performance as reliability, responsiveness, agility, cost and asset management. Use it to locate the failing process, not as a list to recite.
- Bullwhip effect. Variance amplifies upstream through demand forecast updating, order batching, price promotion and rationing/gaming. Remedies: shared point-of-sale data, VMI, CPFR, shorter replenishment cycles and stable pricing.
- Risk and resilience. Map tier 1 and tier 2 dependencies, single points of failure, lead-time and currency exposure. Mitigate with dual sourcing, nearshoring, strategic buffer, contractual continuity requirements and supplier financial monitoring.
Worked example
A medical device manufacturer buys a speciality resin from one supplier in one region, 12-week lead time, annual spend £4m. Demand is volatile; a stock-out would halt a production line at an estimated £600,000 per event, with a 25% annual probability.
Reasoning: classify the item as strategic (high profit impact, high supply risk). Qualifying a second source adds about 3% to unit cost, roughly £120,000 a year, while expected annual stock-out cost is £150,000 before reputational and regulatory harm. Dual sourcing is economically justified and creates competitive tension. Layer on VMI or consignment stock to cover the lead-time gap, and map the supplier's own resin feedstock source, because a tier-2 failure defeats tier-1 management. Set KPIs for on-time-in-full and order-cycle time, reviewed quarterly.
Traps that cost marks
Describing the bullwhip effect without proposing mitigations; treating responsiveness as free; recommending dual sourcing without quantifying the premium; confusing risk transfer (insurance) with risk reduction; failing to link the recommendation back to the organisation's competitive strategy.
