Study Notes

Lack of Supply Chain Coordination and the Bullwhip Effect

Lack of coordination occurs due to conflicting objectives among different stages or delayed and distorted information.
The bullwhip effect results in fluctuations in orders increasing as they move up the supply chain from retailers to suppliers.
Example: Procter & Gamble (P&G) observed the bullwhip effect in the supply chain for Pampers diapers, with steady consumer demand but fluctuating raw material orders.

The Effect on Performance of Lack of Coordination

Lack of coordination increases variability and costs while reducing overall supply chain surplus.
Impacts include:
- Increased manufacturing costs due to excess capacity or inventory.
- Higher inventory costs due to buffering against variability.
- Increased replenishment lead time due to inefficiencies.
- Increased transportation costs due to variable shipping quantities.
- Decreased product availability due to mismatched supply and demand.
- Decreased profitability across the supply chain.

Obstacles to Coordination in a Supply Chain

Incentive obstacles: Misaligned incentives lead to actions that increase variability.
Information-processing obstacles: Distorted demand information as it moves up the supply chain.
Operational obstacles: Large order batches and infrequent orders increase variability.
Pricing obstacles: Pricing strategies like promotions can lead to forward buying and order variability.
Behavioral obstacles: Lack of trust and communication among supply chain partners.

Managerial Levers to Achieve Coordination

Aligning goals and incentives: Ensure all participants aim to maximize total supply chain profits.
Improving information visibility and accuracy: Share demand data across the supply chain to reduce information distortion.
Improving operational performance: Reduce lot sizes and lead times.
Designing pricing strategies to stabilize orders: Use volume-based discounts and everyday low pricing (EDLP) to reduce order variability.
Building strategic partnerships and trust: Foster trust and collaboration to enhance information sharing and reduce duplicated efforts.

Continuous Replenishment and Vendor-Managed Inventories

Continuous replenishment programs (CRPs) and vendor-managed inventories (VMIs) involve suppliers managing inventory levels based on actual sales data.
Examples: Walmart uses CRP and VMI systems to manage inventory levels efficiently and reduce variability.

Collaborative Planning, Forecasting, and Replenishment (CPFR)

CPFR involves joint planning and forecasting among supply chain partners to ensure all stages operate with a common forecast and replenishment strategy.
Requires changes in organizational structure and technology implementation for scalability.
Examples: CPFR implementation requires cross-functional teams and integrated technology solutions to share forecasts and historical data.

Achieving Coordination in Practice

Quantify the bullwhip effect: Measure the variability in orders and its impact on the supply chain.
Secure top management commitment: Coordination efforts need support from top management.
Devote resources to coordination: Establish teams responsible for coordination efforts.
Enhance communication: Regularly communicate with all stages of the supply chain to facilitate information sharing and coordination.
Examples: Walmart and P&G set up collaborative teams for forecasting and replenishment, supported by top management commitment.
