Portfolio Analysis Techniques for Supply Chain Relationships
Portfolio analysis identifies where to focus procurement effort, what relationship to build with each supplier, and where vulnerability lies. Three techniques work together: supply positioning (Kraljic), supplier preferencing, and the market management matrix. AC 1.2.
Pareto and ABC — context, not portfolio
The Pareto principle (80/20) holds that roughly 80% of spend sits with 20% of suppliers. ABC analysis applies the same logic: A items ≈ 80% of cost and 20% of volume; B items in the middle; C items are low-cost, high-volume. Useful for directing effort, but the CIPS source is explicit: ABC does not consider supply risk or strategic impact, gives no relationship recommendation, and is not a portfolio technique — treat it as prioritisation context only.
The Kraljic model (supply positioning)
Maps purchases against financial/profit impact (vertical) × supply risk (horizontal), and underpins category management.
| Quadrant | Position | Typical strategy |
|---|---|---|
| Routine | Low risk / low value (e.g. MRO, stationery) | Procurement cards, reverse auctions, call-off contracts; arm's-length, transactional |
| Bottleneck | High risk / low value (e.g. OEM parts, computer chips) | Few suppliers, limited availability; long-term contracts, buffer stock, seek alternatives |
| Leverage | Low risk / high value | Competitive tendering, target pricing, consortia procurement |
| Strategic | High risk / high value | Long-term partnership, balanced power, strategic alliance, co-destiny |
Supply risk arises from (1) individual supplier failure — quality, delivery, price — or (2) market characteristics such as few suppliers or volatile demand (Zsidisin, 2003). Risk can be internal or external — the STEEPLE factors on the competitive-forces page describe external supply-risk drivers. A common formula: Total risk = Likelihood × Impact.
Benefits: simple, applicable to all industries, clarifies item importance, guides relationship choice. Limitations: subjective; only a snapshot; applies to products and services, not the supplier itself; limited academic foundation.
Exam trap: financial impact is always the vertical axis, supply risk always horizontal — flip them and every quadrant's placement and strategy changes.
Supplier preferencing model
Shows how the supplier views the buyer. Axes: account attractiveness — profitability, growth, contract stability, ethics, and willingness to collaborate — (vertical) × relative value of the business to the supplier (horizontal).
| Quadrant | What it signals | Buyer response |
|---|---|---|
| Core (high attractiveness / high value) | Supplier's priority account; best service level | Cosset; defend vigorously |
| Development (high attractiveness / low value) | Supplier wants to grow the account | Reward with additional business to move toward Core |
| Nuisance (low / low) | Supplier indifferent; may de-prioritise or withdraw | Try to increase the account's attractiveness to move it toward Development |
| Exploitable (low attractiveness / high value) | Supplier extracts a premium; short-term view | Find business the supplier would find attractive to pull it toward Core |
Advantage: reveals information the buyer may not have. Limitation: snapshot based on the buyer's judgement.
Market management matrix
Combines the Kraljic view (buyer's perspective) with the preferencing view (supplier's perspective) to set strategy. The most vulnerable position: a strategic item where the supplier views the buyer as nuisance or exploitable — misaligned views signal urgent action is needed. The matrix shows when a change of relationship is needed, not just a change of supplier — so the buyer does not try to build a relationship a supplier has no interest in. Insights feed SRM action plans, monitored via the Plan-Do-Check-Act (PDCA) cycle.
Running the segmentation
(1) List purchases in descending order of value. (2) Evaluate supply risk and market complexity for each. (3) Plot each item on the Kraljic matrix. (4) Apply the supplier preferencing model to understand how the supplier views the account. (5) Use the market management matrix to set the strategy. (6) Review regularly — positions are a snapshot; markets and relationships change, and re-evaluation should be a scheduled discipline, not a one-off.
Why positioning pays off
All three techniques share the same return: they identify opportunities for competitive advantage, provide a framework for decision-making and action planning, and improve risk management by exposing which products and suppliers are a vulnerability. Concrete procurement objectives include moving non-contract spend onto contract, identifying strategic items that merit investment, and building value-adding relationships where they genuinely pay off.
Key terms
- Pareto / ABC analysis — spending prioritisation: ~80% of spend from ~20% of suppliers; not a portfolio technique.
- Kraljic model — supply positioning matrix: financial impact (vertical) × supply risk (horizontal); four quadrants: Routine, Bottleneck, Leverage, Strategic.
- Supplier preferencing model — the supplier's view of the buyer: account attractiveness × relative business value; four quadrants: Core, Development, Nuisance, Exploitable.
- Market management matrix — combines buyer and supplier views to recommend relationship strategy; highlights misalignment.
- PDCA — Plan-Do-Check-Act; framework for monitoring SRM action plans against desired outcomes.
- Consortia procurement — pooling volumes across organisations to gain leverage (Leverage quadrant).
