Category management in procurement: the Kraljic matrix and a category plan
Category management organises procurement around groups of related goods and services (categories) rather than around individual purchase requests. Each category gets an owner, a strategy based on its market and its importance to the business, and a multi-year plan. It is the main way large procurement functions move from processing orders to shaping what the organisation buys and from whom.
What counts as a category
A category is a group of purchases that share a supply market: suppliers that compete with each other, similar cost drivers and similar buying skills. "Logistics" is usually too broad to manage as one category; "road freight", "ocean freight" and "warehousing" are more workable because each has its own suppliers and pricing logic. The spend analysis taxonomy is the natural starting point, adjusted so that each category corresponds to a real market.
The category management cycle
- Analyse. Gather internal data (spend, volumes, specifications, contracts, users' needs and complaints) and external data (market structure, main suppliers, capacity, cost drivers, regulation, technology trends). Tools such as Porter's five forces or a simple cost breakdown of the product help explain where supplier power and price pressure come from.
- Position. Decide how important the category is to the business and how difficult the supply market is. The Kraljic matrix (below) is the classic tool.
- Set the strategy. Choose levers that fit the position: competition, consolidation, demand management, specification change, partnership, risk mitigation.
- Implement. Run the sourcing events, negotiations and changes the strategy calls for (see RFI, RFP and RFQ and negotiation basics).
- Manage and review. Track supplier performance, savings and risks, and refresh the strategy typically every one to three years or when the market shifts.
The Kraljic matrix
In a 1983 Harvard Business Review article, "Purchasing Must Become Supply Management", Peter Kraljic proposed classifying purchases along two dimensions: their profit impact (or importance to the business, often approximated by spend and effect on product quality or revenue) and supply risk (the difficulty and risk of securing supply, reflecting the number of suppliers, substitutes, scarcity and switching costs). The result is four quadrants.
| Quadrant | Profit impact / supply risk | Typical examples | Typical strategy |
|---|---|---|---|
| Non-critical (routine) | Low / low | Office supplies, standard MRO items | Simplify and automate: catalogues, purchasing cards, aggregated contracts, minimal buyer time. |
| Leverage | High / low | Commodity materials, standard packaging, many indirect services | Use buying power: competitive tenders, volume consolidation, e-auctions, index-linked pricing. |
| Bottleneck | Low / high | A specialised component from one approved source, niche spare parts | Secure supply: safety stock, long-term agreements, qualifying alternatives, redesigning to standard parts. |
| Strategic | High / high | Key technologies, critical raw materials, core outsourced services | Partner and plan: long-term relationships, joint development, shared forecasts, careful risk management. |
The matrix is valuable because it stops a team from applying one approach to everything. Running an aggressive e-auction on a bottleneck item can damage the only supplier you have; spending weeks negotiating stationery is wasted effort. Its limits are equally important: positions are judgements, not measurements; the matrix looks at categories from the buyer's side only; and items move between quadrants as markets change. A useful complement is to consider how the supplier sees you: whether your account is attractive and significant to them affects how much leverage or partnership is realistic.
Writing a category strategy
A category strategy is a short document, often a few pages, that stakeholders can read and agree. A practical outline:
- Scope: what is in and out of the category, sites and business units covered.
- Baseline: annual spend, suppliers and their shares, contract status and expiry dates, current performance issues.
- Business requirements: what users and leadership need from the category over the next years (growth, quality, service, sustainability targets).
- Market analysis: structure, key suppliers, price drivers, risks and opportunities.
- Positioning and the strategy that follows from it.
- Initiatives: specific actions (tender, consolidate, renegotiate, redesign, qualify a second source) with timing, owner and expected benefit.
- Risks and how they will be mitigated (see supplier risk and resilience).
- KPIs to track success: savings or cost avoidance against a defined baseline, compliance with contracts, supplier performance, risk indicators.
Levers beyond price
Price negotiation is only one lever, and often not the largest. Others include:
- Demand management: buying less, for example by cutting unused software licences or reducing service frequency.
- Specification: standardising parts, removing over-specification, using performance specifications to let suppliers propose cheaper solutions.
- Total cost: changing payment terms, Incoterms, packaging or delivery frequency (see total cost of ownership).
- Supplier base: consolidating to fewer suppliers for leverage, or adding suppliers for resilience.
- Process: moving tail spend to catalogues, automating ordering, improving forecasts shared with suppliers.
- Make or buy: in some cases, bringing work in-house or outsourcing it.
- Sustainability and circularity: reuse, refurbishment, take-back schemes (see circular procurement).
Stakeholders make or break it
Category management fails most often not on analysis but on adoption. Users who were not consulted keep buying from their preferred suppliers. Good practice is to form a small cross-functional team per major category, with representatives from the main using functions, finance and, for technical categories, engineering or IT; to agree requirements with them before going to market; and to report results in terms they care about (service, risk, budget) as well as savings.
