DEP–GARD Supply Chain: Logistics Solutions for Polymer Delivery
This case study examines the business relationship between DuPont Engineering Polymers (DEP) and Gard Automotive Manufacturing (GARD), where a new purchasing agent has pressured DEP to shorten lead times and improve service reliability. The paper identifies three potential solutions—outsourcing to common carriers, advance production planning, and warehouse efficiency improvements—and recommends carrier-based logistics as the primary intervention. Implementation requires identifying qualified carriers, negotiating service agreements, and establishing daily pickup and delivery routines to meet GARD's inventory management objectives and competitive bidding criteria.
- Major Facts: DEP-GARD 15-year relationship disrupted by new purchasing agent
- Major Problem: Order-to-delivery time and service minimums must improve
- Possible Solutions: Three operational strategies to accelerate fulfillment
- Choice and Rationale: Common carriers selected as primary solution
- Implementation: Carrier identification and negotiation roadmap

What makes this paper effective
- Clear problem structure: Opens with a concrete business relationship, identifies the triggering event (new purchasing agent), and states the core challenge explicitly.
- Systematic solution evaluation: Presents multiple alternatives with pros and cons rather than jumping to one answer, demonstrating analytical rigor typical of case study methodology.
- Practical implementation focus: Moves beyond abstract recommendations to outline concrete steps (identifying carriers, requesting quotes, negotiation process) that a company could actually execute.
- Supply chain perspective: Recognizes interdependencies between order placement, production, warehousing, and delivery—showing systems-level thinking.
Key academic technique demonstrated
This paper employs the classic case study problem-solving framework: situation analysis → problem definition → alternative generation → decision with rationale → implementation roadmap. The structure mirrors how business consultants and operations managers approach real-world challenges. By explicitly rejecting two alternatives with stated reasoning (cost/risk concerns), the author demonstrates weighing trade-offs rather than presenting an obviously correct answer.
Structure breakdown
The paper follows a linear narrative arc moving from context (facts) through diagnosis (problem) to treatment plan (solutions, choice, implementation). The supply chain diagram in the appendix visualizes the current workflow, anchoring abstract discussion to concrete process steps. This format is typical of undergraduate or early graduate case study assignments in operations management or supply chain courses.
Major Facts
This case study examines the business relationship between DuPont Engineering Polymers (DEP), a supplier, and Gard Automotive Manufacturing (GARD), a customer. DEP has supplied polymers to GARD for 15 years. Historically, the acquisition process was conducted as a closed auction with only DEP invited to bid, resulting in multi-year contracts. GARD was satisfied with the quality of DEP's products and had no incentive to negotiate with alternative suppliers.
This stable arrangement changed when GARD assigned a new purchasing agent to oversee polymer acquisition negotiations. The new agent expressed dissatisfaction with both the contract duration and the delivery performance offered by DEP. Rather than renew a multi-year agreement, the agent limited the next contract to one year and announced plans to evaluate samples from competing suppliers. This shift forced DEP to reconsider its competitive position and operational capabilities.
