Week 2

Impact of Globalization on Supply Chain Networks

• Globalization presents substantial opportunities to simultaneously grow revenues and decrease operational costs across supply chain networks.

• Increased global reach is accompanied by significant additional risk factors that must be systematically managed.

• The distinction between success and failure in global supply chain operations frequently depends on the ability to incorporate suitable risk mitigation strategies directly into the supply chain design.

• Demand and price uncertainty directly drive the strategic value of constructing flexible production capacity.

• Impact of Risk Factors on Supply Chains:

  • Performance of supply chain partners: $38\%$

  • Volatility of fuel prices: $37\%$

  • Natural disasters: $35\%$

  • Logistics capacity/complexity: $33\%$

  • Forecasting/planning accuracy: $30\%$

  • Currency fluctuation: $29\%$

  • Supplier planning/communication issues: $27\%$

  • Shortage of skilled resources: $24\%$

  • Port operations/custom delays: $23\%$

  • Customer/consumer preference shifts: $23\%$

  • Inflexible supply chain technology: $21\%$

  • Geopolitical uncertainty: $20\%$

  • Terrorist infiltration of cargo: $13\%$

The Offshoring Decision and Total Cost Analysis

• Offshoring decisions must capitalize on comparative advantage within global supply chains by explicitly quantifying financial benefits alongside non-financial strategic drivers.

• Primary Causes of Offshoring Failure:

  • Focusing exclusively on unit cost rather than evaluating total landed cost.

  • Ignoring critical risk factors inherent to international sourcing and extended supply networks.

• Impact of Offshoring Across Supply Chain Performance Dimensions:

  • Order Communication:

  • Impacting Activity: Order placement.

  • Offshoring Impact: Communication becomes more difficult across time zones, languages, and cultures.

  • Supply Chain Visibility:

  • Impacting Activity: Scheduling and expediting.

  • Offshoring Impact: Poorer visibility across extended network nodes.

  • Raw Material Costs:

  • Impacting Activity: Sourcing of raw material.

  • Offshoring Impact: Cost impact can fluctuate in either direction depending on localized sourcing options.

  • Unit Cost:

  • Impacting Activity: Production, quality (production and transportation).

  • Offshoring Impact: Labor and fixed costs decrease, but product quality may suffer.

  • Freight Costs:

  • Impacting Activity: Transportation modes and quantity.

  • Offshoring Impact: Substantially higher freight costs due to distance and multimodal transit.

  • Taxes and Tariffs:

  • Impacting Activity: Border crossing.

  • Offshoring Impact: Variable impact depending on international trade agreements and regional duty structures.

  • Supply Lead Time:

  • Impacting Activity: Order communication, supplier production scheduling, production time, customs, transportation, and receiving.

  • Offshoring Impact: Longer lead times degrade forecast accuracy and require higher baseline safety inventories.

  • On-Time Delivery / Lead Time Uncertainty:

  • Impacting Activity: Production, quality, customs, transportation, and receiving.

  • Offshoring Impact: Poorer on-time delivery performance and higher lead time uncertainty, driving higher inventory levels and lower overall product availability.

  • Minimum Order Quantity (MOQ):

  • Impacting Activity: Production and transportation.

  • Offshoring Impact: Larger minimum order quantities required by offshore suppliers increase holding costs and average inventory levels.

  • Product Returns:

  • Impacting Activity: Quality control.

  • Offshoring Impact: Increased probability of product returns due to quality variances.

  • Inventories:

  • Impacting Activity: Lead times, inventory in transit, and safety stock.

  • Offshoring Impact: Overall inventory levels increase significantly across the pipeline.

  • Working Capital:

  • Impacting Activity: Inventories and financial reconciliation cycle time.

  • Offshoring Impact: Working capital requirements increase substantially.

  • Hidden Costs:

  • Impacting Activity: Order communication, invoicing errors, and foreign exchange risk management.

  • Offshoring Impact: Significantly higher operational and administrative hidden costs.

  • Stock-Outs:

  • Impacting Activity: Ordering, production, and transportation under limited visibility.

  • Offshoring Impact: Higher frequency of stock-outs.

• Flow Dimensions and Cost Tracking:

  • Offshoring expands both the geographic length and temporal duration of information, product, and cash flows.

  • The operational complexity and cost of managing offshored supply chains frequently surpass initial projected estimates.

  • Organizations must continuously quantify and track all total cost factors over time.

  • Managing heightened risk and its consequential cost impacts represents the central operational challenge in global offshoring.

• Eight Key Elements of Total Cost:

  1. Supplier price.

  2. Terms of purchase and payment.

  3. Delivery costs (shipping, handling, and freight).

  4. Inventory and warehousing costs.

  5. Cost of quality (defects, rework, and returned goods).

  6. Customs duties, value-added taxes (VAT), and local tax incentives.

  7. Cost of risk, procurement staff overhead, broker fees, infrastructure costs, and tooling/mold expenses.

  8. Exchange rate trends and their financial impact over time.

Risk Categories and Risk Drivers in Global Supply Chains

• Global supply chain risks encompass supply disruptions, delivery delays, demand fluctuations, price volatility, and exchange-rate risks.

• Proactive network design requires identifying specific risk categories and their underlying drivers.

• Categorization of Risk Drivers:

  • Disruptions:

  • Drivers: Natural disasters, war, terrorism, labor disputes, and supplier bankruptcy.

  • Delays:

  • Drivers: High capacity utilization at the supply source, inflexibility of the supply source, and poor quality or yield at the supply source.

  • Systems Risk:

  • Drivers: Breakdown of information infrastructure, improper system integration, or excessive networked dependencies across systems.

  • Forecast Risk:

  • Drivers: Inaccurate forecasts caused by long lead times, demand seasonality, broad product variety, short product life cycles, small customer bases, and information distortion (bullwhip effect).

  • Intellectual Property Risk:

  • Drivers: Vertical integration of the supply chain versus global outsourcing and exposure to foreign regulatory jurisdictions.

  • Procurement Risk:

  • Drivers: Exchange-rate fluctuations, input price volatility, high percentage of materials purchased from a single source, and industry-wide capacity utilization rates.

  • Receivables Risk:

  • Drivers: Concentration of customer base and underlying financial strength/solvency of customers.

  • Inventory Risk:

  • Drivers: High rate of product obsolescence, elevated inventory holding costs, high unit product value, and high demand/supply uncertainty.

  • Capacity Risk:

  • Drivers: High cost of capacity installation and overall flexibility of capacity.

Risk Mitigation Strategies in Global Supply Chains

• Supply chain network design serves as a foundational instrument for mitigating long-term operational risks.

• Every mitigation strategy incurs direct financial expenses and may introduce secondary risks that require management.

• Global networks should combine rigorously evaluated operational mitigation tactics with financial strategies to hedge unmitigated risks.

• Tailored Mitigation Strategies Matrix:

  • Increase Capacity:

  • Tailored Approach: Focus on low-cost, decentralized capacity for predictable demand. Build centralized capacity for unpredictable demand. Increase decentralization as capacity installation costs decline.

  • Get Redundant Suppliers:

  • Tailored Approach: Maintain higher supplier redundancy for high-volume products and lower redundancy for low-volume products. Centralize redundancy for low-volume products across a limited set of flexible suppliers.

  • Increase Responsiveness:

  • Tailored Approach: Prioritize low cost over responsiveness for standardized commodity products. Prioritize responsiveness over cost for short–life cycle products.

  • Increase Inventory:

  • Tailored Approach: Decentralize inventory holding for predictable, lower-value products. Centralize inventory for unpredictable, higher-value products.

  • Increase Flexibility:

  • Tailored Approach: Prioritize cost over flexibility for predictable, high-volume products. Favor flexibility for unpredictable, low-volume products. Centralize flexibility in a few strategically located facilities if flexibility costs are high.

  • Pool or Aggregate Demand:

  • Tailored Approach: Scale up demand aggregation as demand unpredictability increases.

  • Increase Source Capability:

  • Tailored Approach: Prefer supplier capability over cost for high-value, high-risk products. Favor cost over supplier capability for low-value commodity goods. Centralize high-capability processes in flexible facilities whenever possible.

Flexibility, Chaining, and Containment

• Three Broad Categories of Flexibility:

  • New Product Flexibility: The capability to introduce new products into the market at a rapid rate.

  • Mix Flexibility: The ability to manufacture a diverse variety of products within a short timeframe.

  • Volume Flexibility: The ability to operate profitably across widely varying levels of production output.

• Network Configurations and Chaining Principles:

  • Dedicated Network:

  • Each plant is dedicated to producing for a specific local market or product line.

  • Contains zero operational flexibility across nodes, making it vulnerable to local demand shifts.

  • Fully Flexible Network:

  • Every plant is equipped and capable of supplying every market node.

  • Provides maximum risk pooling but requires extreme capital investment and complex operational management.

  • Chained Network with One Long Chain:

  • Facilities are linked sequentially so that each plant can supply its local market and one adjacent market.

  • Creates a single continuous chain of capacity sharing across the entire network.

  • Chained Network with Two Short Chains:

  • Network flexibility is partitioned into smaller, independent closed loops or sub-chains.

  • Contains flexibility and disruptions within smaller operational subsets.

• Performance and Trade-offs of Chaining:

  • Marginal benefits derived from adding flexibility decrease as overall network flexibility increases (diminishing marginal returns).

  • Under conditions of demand uncertainty, long chains pool capacity effectively across regions, delivering performance close to a fully flexible network at a significantly lower cost.

  • A single long chain can incur higher fixed costs and introduces significant coordination complexity across disparate geographic regions.

  • Flexibility and chaining strategies effectively manage demand fluctuations, but are less effective in mitigating major supply disruptions (such as physical facility destruction or catastrophic transportation shutdowns).
