Spec mapping: AQA 7138 Unit 3.2.2 — Operations Management (refer to the official AQA specification document for exact wording). This lesson develops supply-chain management at A-Level depth — the multi-tier supply-chain structure, supplier-selection criteria, the arms-length vs partnership relationship split, the modern themes of globalisation, sourcing strategies, lead-time and resilience management, the post-2020 resilience-vs-efficiency recalibration, and crucially the NEW 7138 content on supply-chain transparency, ESG reporting and codes of conduct. The 15-mark Evaluate on this lesson is the second discriminator tariff for this batch — Top-band 15/15 must visibly deploy ≥2 Annex 8 sophisticated concepts including the ESG / stakeholder dimension, with examiner-style commentary calling out which concepts lifted the answer. The embedded-ethics dimension must be visible throughout; this is not an add-on but the substantive content of the modern supply-chain question.

Definition: Supply-chain management (SCM) is the coordinated management of all activities involved in sourcing, procurement, production, distribution and delivery of products — from the originating raw material through to the end customer. A modern supply chain is typically a multi-tier network rather than a linear chain, with tier-1 direct suppliers, tier-2 suppliers-of-suppliers, and so on; the buying business's reputational and operational exposure typically reaches at least to tier 2, often further.
Supply chains have moved from operational backwater to strategic centre over the last decade. Three forces account for the shift:
The strategic move at A-Level is to refuse the textbook framing of supply chains as cost-minimisation infrastructure. The exam-relevant question is which supply-chain configuration aligns with the business's competitive position, brand promise, regulatory exposure, and ESG-rating ambition — and the answer is rarely "the cheapest available sourcing".
| Tier | Role | Example (mid-market apparel retailer) |
|---|---|---|
| Raw-material producers | Originating commodity supply | Cotton farms in India / Pakistan / Uzbekistan |
| Tier-2+ suppliers | Processing into intermediates | Ginning mills, spinning mills, weaving mills, dye-houses |
| Tier-1 suppliers (direct) | Producing the finished input | Garment factories in Bangladesh / Vietnam / Turkey |
| Logistics providers | Inbound transport, port handling, warehousing | Freight forwarders, customs brokers, 3PL warehouses |
| The buying business | Retail operation | Apparel retailer's distribution network |
| Channel partners | Sale to end customer | High street stores, e-commerce platform, marketplace sellers |
| End customer | Purchase and use | The customer wearing the garment |
The complexity is that the buying business has direct contractual relationships only with tier-1 suppliers; visibility to tier-2 and beyond depends on the supplier's willingness to disclose, the buying business's audit capability, and the regulatory regime that compels disclosure. Supply-chain transparency is the operational discipline of building visibility through the multi-tier structure.
Three structural sourcing choices define the supply-chain configuration:
| Strategy | Description | Trade-off |
|---|---|---|
| Global sourcing (offshoring) | Source from the lowest-cost qualified supplier worldwide | Lowest unit cost; longest lead times; highest disruption risk; weakest transparency |
| Nearshoring | Source from suppliers in the buying business's region (e.g., Eastern Europe, North Africa for UK / EU buyers) | Moderate unit cost; medium lead times; moderate disruption risk; improved transparency |
| Reshoring (onshoring) | Bring sourcing back to the home country | Highest unit cost; shortest lead times; lowest disruption risk; strongest transparency and brand-narrative support |
Post-2020 the strategic axis has shifted decisively from pure offshoring towards nearshoring and reshoring — driven by the disruption-cost recalibration, the rising relative cost of distant labour as wages converge, and the supply-chain transparency dimension that local sourcing supports more easily.
A fourth dimension — multi-sourcing vs single-sourcing — cuts across the geographical choice. Multi-sourcing (multiple suppliers for the same input) builds resilience but reduces partnership-relationship depth; single-sourcing (one preferred supplier) builds partnership depth but concentrates supplier-dependence risk.
The relationship between buyer and supplier sits on a spectrum from adversarial-transactional to collaborative-partnership.
| Dimension | Arms-length (adversarial) | Partnership (collaborative) |
|---|---|---|
| Number of suppliers | Many | Few |
| Contract length | Short-term, competitive tender | Long-term, multi-year |
| Information sharing | Minimal | Extensive (forecasts, cost data, design) |
| Trust | Low — buyer plays suppliers against each other | High — mutual commitment to the relationship |
| Focus | Price | Total value (quality, innovation, reliability, ethics) |
| Switching costs | Low | High |
| Risk profile | Diversified across suppliers | Concentrated in few suppliers |
| Compatible with JIT | Difficult | Natural |
| Compatible with ESG transparency | Limited (audit cost per supplier high) | Strong (deep relationships support audit) |
Toyota's keiretsu network of long-term supplier partnerships is the canonical model — Toyota invests in supplier training, shares technology, and treats supplier development as a long-run strategic priority. The keiretsu model supports JIT, joint quality improvement, and synchronised innovation in ways adversarial sourcing structurally cannot.
This is the substantive new content area for the September-2026 specification cohort. Three interlocking developments:
A supplier code of conduct is the buying business's articulation of the labour, environmental, and ethical standards required of suppliers as a condition of doing business. Modern codes typically cover:
Codes are necessary but not sufficient — code-on-paper without audit, consequence and remediation is performative.
Supplier compliance is verified through periodic audits — first-party (buyer audits supplier), second-party (industry-association audits), or third-party (independent audit body). Common certification schemes include:
| Scheme | Coverage |
|---|---|
| SA8000 | Workplace labour standards |
| ISO 14001 | Environmental management systems |
| Fairtrade | Producer-side fair pricing and labour standards in commodity supply |
| GOTS (Global Organic Textile Standard) | Organic and labour standards in textile supply |
| B Corp | Whole-business sustainability and governance certification |
| Sedex / SMETA | Multi-buyer audit-sharing platform for labour and ethical compliance |
Certification is a signal of compliance, not a guarantee — the Rana Plaza factory had been audited multiple times before collapse, and audit-fraud is a documented industry problem.
ESG reporting requirements increasingly extend through the supply chain:
The strategic implication: a supplier-base configuration that maximises short-run unit-cost saving but compromises supply-chain transparency is increasingly costly when ESG-rating consequences, regulatory liability, and brand-reputational risk are weighed.
The pre-2020 supply-chain orthodoxy optimised for efficiency — global sourcing, JIT inventory, single-sourcing for scale, minimum buffer. The post-2020 reality is a recalibration towards resilience:
| Resilience lever | Mechanism |
|---|---|
| Multi-sourcing on critical inputs | Two-or-more suppliers per critical component to absorb single-supplier failure |
| Strategic buffer stock | JIC for critical inputs even as JIT continues for routine inputs |
| Nearshoring / reshoring | Shorter, more visible supply chains less exposed to long-distance disruption |
| Supplier financial-stability monitoring | Avoid the supplier-bankruptcy disruption pattern that COVID exposed |
| Scenario planning | Map disruption scenarios and pre-position responses |
| Inventory pooling | Share buffer stock across multiple end uses to reduce total holding |
| Dual-purpose flexibility | Manufacturing assets capable of producing multiple end products to absorb mix shocks |
The trade-off: resilience costs more in normal times (carrying capacity is more expensive than running flat-out; multi-sourcing forfeits some scale economies; nearshoring pays a wage-cost premium) and saves more in disrupted times. The strategically rigorous answer reads resilience-vs-efficiency as a risk-management question, not a cost-comparison question.

The diagram captures the modern supply-chain decision structure — sourcing and relationship choices interact with visibility, which enables ESG compliance, which determines the risk profile and stakeholder consequences. The dotted feedback loop is critical — strategy is revised as supply-chain transparency, ESG-rating and stakeholder evidence accumulate.
Brookleigh Apparel is a hypothetical UK mid-market women's-fashion retailer with 87 high-street stores and a growing online channel (38 % of 2025 revenue, up from 14 % in 2021), established 1994 and employing 1,840 people across stores, distribution, head office and design. 2025 revenue was £162 million; gross margin 47 %; operating profit margin 6.1 %. Sourcing is currently dominated by long-tail tier-1 garment factories in Bangladesh (52 %), China (18 %), Turkey (14 %) and Vietnam (9 %); 78 tier-1 suppliers in total. The current supplier-audit regime is SMETA-shared third-party audit every 24 months, with no tier-2 visibility. The board is weighing two structural sourcing options to support the next phase of strategy. Option A: lowest-cost overseas continuation — consolidate the supplier base from 78 to ~30 tier-1 partners (mainly Bangladesh + Vietnam, with selected Turkey for fast-response), continue 24-month SMETA audit only, target a 6 % reduction in landed unit cost. Option B: nearshoring with full transparency — shift ~55 % of volume to Turkey, Morocco and Portugal, build a tier-2-visible supplier-tracking platform, commit to annual third-party audits at tier-1 plus risk-based tier-2 audits, publish a full supplier-list, and pursue B Corp certification. Estimated landed unit cost rises by approximately 9 %; lead time falls from 18 weeks to 6–8 weeks (a structural benefit for fast-fashion responsiveness); the £8.4m of incremental cost is partly offset by the lead-time-driven inventory-days reduction (estimated working-capital release of £4.1m). The board chair has flagged that institutional investors (Brookleigh is AIM-listed) are increasingly ESG-screening, and that two recent journalistic investigations into the broader Bangladesh apparel supply chain are putting reputational pressure on UK mid-market retailers.

Evaluate the two sourcing options for Brookleigh Apparel and recommend which the board should pursue. (15 marks)
| AO | What the question rewards | Mark weighting on this 15-mark item |
|---|---|---|
| AO1 | Knowledge of sourcing strategies, supplier-relationship spectrum, supply-chain transparency, ESG reporting (Scope 3, Modern Slavery Act, CSRD), B Corp certification | ~3 marks |
| AO2 | Application to Brookleigh's specific figures — 78 → 30 supplier consolidation, 52 % Bangladesh concentration, 9 % cost premium, 18 → 6-8 weeks lead time, £4.1m working-capital release, AIM-listed ESG-screening pressure | ~3 marks |
| AO3 | Analytical chain-of-reasoning — net cost-benefit of Option B (£8.4m premium net of £4.1m working-capital release plus inventory-turnover and fast-fashion responsiveness benefit), ESG-rating implications, reputational-risk asymmetry, supplier-relationship depth implications | ~5 marks |
| AO4 | Evaluative judgement — weighing the two options against Brookleigh's strategic position to issue a recommendation; visible deployment of ≥2 Annex 8 sophisticated concepts including ESG dimension | ~4 marks |
15-mark Evaluate items reward a structured "set up the framework / work each option arithmetically / weigh the trade-offs / issue a recommendation" build. The Top-band discriminator on this specific question is the visible engagement with the ESG / stakeholder dimension as substantive analytical content, not as an ethics-paragraph add-on.
Brookleigh Apparel must choose between Option A (lowest-cost overseas continuation, 6 % cost reduction) and Option B (nearshoring with transparency, 9 % cost premium offset by £4.1m working-capital release). The decision is about more than cost — it engages supply-chain transparency, ESG-investor pressure, and the lead-time competitiveness of the online channel.
Option A consolidates the supplier base from 78 to ~30 suppliers and delivers a 6 % landed cost reduction. On gross margin of 47 %, a 6 % cost reduction lifts gross margin by roughly 3 percentage points, equivalent to about £4.9m of additional gross profit at £162m revenue. This is significant for a £9.9m operating-profit business. However, Bangladesh concentration rises and tier-2 visibility remains zero, leaving Brookleigh exposed to any future scandal in the upstream supply chain.
Option B shifts 55 % of volume to nearshore (Turkey, Morocco, Portugal) and builds full tier-1 audit + risk-based tier-2 audit + supplier-list publication + B Corp certification. The 9 % landed cost premium is roughly £14.6m gross uplift (47 % × £162m × 9 %... or more precisely, the cost-of-goods uplift is £8.4m as stated). After the £4.1m working-capital release, the net annual cost is £4.3m. Lead time falls from 18 weeks to 6-8 weeks, which is a major benefit for the fast-fashion online channel (38 % of revenue) where speed-to-market matters more than for store-based ranges.
On balance, Option B is the right choice. The £4.3m net cost is roughly 43 % of one year's operating profit, but it buys (i) ESG-rating protection in an AIM-listed environment where institutional investors are increasingly screening, (ii) reputational protection in a sector where Rana-Plaza-type events recur, (iii) fast-fashion lead-time competitiveness against online-pure-play competitors. Option A delivers a one-off margin gain but locks in transparency-poor sourcing that is increasingly costly. I would recommend Option B.
