Teaching Global Sourcing Decisions in the Classroom — Why Static Case Studies Fail

Every supply chain lecturer has been there: students read the Harvard case, discuss the Boeing outsourcing disaster or the Rana Plaza collapse with admirable analytical depth, and then sit in an exam room producing essays that feel theoretical and distant. The case study has been the dominant vehicle for supply chain education for forty years. It is also, increasingly, the wrong one.

The Core Problem With Static Cases

A case study is a post-mortem. By definition it describes a situation that has already resolved. Students know, at least implicitly, that the company survived or didn't, that the sourcing decision was vindicated or catastrophic. That foreknowledge removes the one ingredient that makes global sourcing genuinely difficult: radical uncertainty. When a procurement director selects a Tier 1 supplier in Vietnam over one in Poland, they do not know what the next eighteen months hold. Students reading a retrospective case never experience that vertigo — and it is that vertigo that builds real decision-making capacity.

What Professional Bodies Say About Sourcing Competency

CIPS, the Chartered Institute of Procurement and Supply, is explicit in its Level 4 and Level 6 competency frameworks: practitioners must demonstrate the ability to evaluate sourcing options against cost, quality, risk, and sustainability criteria simultaneously — not sequentially. That multi-dimensional trade-off is almost impossible to teach through a case study because the case has already collapsed the trade-off space into a single historical outcome. Simulation preserves the full dimensionality of the decision.

“Students who engage in simulation-based procurement exercises score significantly higher on multi-criteria decision-making assessments than peers taught through case study methods alone.”

— Carter & Rogers, Journal of Supply Chain Management, 2023

Global Sourcing Dimensions Students Must Navigate

• Lead time versus unit cost — the classic near-shore versus far-shore trade-off under variable demand
• Supplier concentration risk — single-source efficiency versus resilience when a supplier fails
• Currency and geopolitical exposure — how exchange-rate shifts and tariff regimes erode cost advantages
• Ethical and sustainability criteria — carbon footprint, labour standards, and modern slavery compliance
• Quality and inspection cost — the hidden total cost that price-only analysis ignores

How Live Simulation Changes the Learning Dynamic

When students make sourcing decisions inside a live simulation, the classroom dynamic shifts from consumption to consequence. A team that over-concentrates on a low-cost single supplier discovers, two turns later, that a simulated port strike has wiped out their inventory buffer. That experience is remembered — not because it was dramatic, but because the students themselves made the decision that caused it. Attribution matters in adult learning. Cases give students someone else's mistake to analyse; simulations give them their own.

SPPIN Sim's Global Sourcing Module in Practice

SPPIN Sim includes a dedicated supply chain sourcing module that confronts teams with exactly these multi-variable trade-offs across sequential turns. Tutors can inject real-world disruption events — derived from live news sources including GDELT — to stress-test sourcing strategies in real time. A team that has selected a supplier in a region that subsequently experiences a logistics disruption must adapt mid-simulation, just as a real procurement team would. The debrief conversation that follows is categorically richer than any case-study discussion because every group has navigated a different path to the same disruption.

Assessment That Reflects the Messiness of the Real World

One practical advantage of simulation-based sourcing education is the assessment trail it leaves behind. Every decision a team makes is logged, timestamped, and linked to outcomes. That data becomes a portfolio artefact: students can narrate their sourcing rationale, trace how their strategy evolved under pressure, and reflect on what they would do differently. That is precisely the evidence-based reflective practice that CIPS professional assessors look for — and it is evidence that emerges naturally from the simulation, not from an artificially constructed assignment prompt.
