Supplier Segmentation and the Kraljic Matrix: How to Manage Every Supplier the Right Way

The two dimensions of the Kraljic Matrix

The Kraljic Matrix plots purchased items (and by extension, the suppliers that provide them) on two axes. The vertical axis is profit impact: how much does this item contribute to the company’s profitability, either directly through its cost as a share of total spend, or indirectly through its role in enabling the company to deliver its products? The horizontal axis is supply risk: how difficult is it to source this item reliably? Supply risk is driven by the number of available suppliers, geographic concentration, switching costs, delivery lead times, and whether the item is a commodity or a proprietary specification.

By scoring each purchased category on both dimensions and plotting the result, procurement teams create a visual map of the supply base that guides how much time, relationship investment, and risk mitigation to apply to each category. The matrix does not need precise numerical scores to be useful; a qualitative high/low classification on each axis is enough to assign categories to quadrants and derive a management strategy.

The four quadrants

Strategic items (high profit impact, high supply risk). These are the items that matter most and are hardest to replace. Typical examples include proprietary components, specialty chemicals, key software licenses, and materials sourced from a single qualified supplier. The procurement strategy for strategic items is collaborative partnership: long-term contracts, joint development programs, supplier capacity reservations, deep integration between the buyer’s and supplier’s planning systems, and regular executive-level relationship reviews. Because the supplier cannot easily be replaced, the buyer must invest in making the relationship work and in making the supplier financially stable and operationally capable. Losing a strategic supplier can halt production; the risk management investment is proportionate to that consequence.

Leverage items (high profit impact, low supply risk). These are high-spend categories where multiple qualified suppliers exist and switching is feasible. Office furniture, standard electronic components, and bulk commodities where several certified sources exist are typical examples. The procurement strategy is competitive leverage: use the availability of alternatives to negotiate aggressively on price, run competitive tenders, consolidate volume to maximize bargaining power, and minimize switching costs to keep the threat of change credible. Buyer power is strong here; the goal is to extract value through competition and consolidation rather than through partnership.

Bottleneck items (low profit impact, high supply risk). These are items that represent a small share of total spend but could halt operations if supply failed. A single-source specialized gasket, a proprietary calibration fluid, or a niche regulatory-compliance component often falls here. The procurement strategy is risk mitigation: hold safety stock, dual-source where possible even at a cost premium, qualify backup suppliers before they are needed, and monitor the supplier’s financial health and operational capacity closely. The cost of holding extra inventory is small compared to the cost of a production stoppage caused by a stock-out of a $5 part.

Non-critical items (low profit impact, low supply risk). These are routine purchases: standard office supplies, cleaning materials, simple maintenance items, and widely available commodities with many interchangeable sources. The procurement strategy is efficiency: automate ordering, use purchasing cards, establish standing agreements with distributors, and minimize the transaction cost of buying. Do not spend procurement management time on items that can be bought off a catalog. The goal is to reduce the administrative burden of routine purchasing to near zero.

How to build the matrix for your organization

Building the matrix starts with an analysis of the purchased item portfolio. For each category (grouping of similar items purchased from one or a small number of suppliers), assess profit impact and supply risk using the criteria most relevant to your industry.

Profit impact is typically assessed by asking: What is the annual spend on this category as a percentage of total cost of goods sold? Does this item directly affect product quality or customer service? What would the cost be if this item were unavailable for a week, a month, a quarter?

Supply risk is assessed by asking: How many qualified, certified suppliers exist for this item? How long would it take to qualify a new supplier if the current one failed? Is this item proprietary (single source) or a commodity (many sources)? Is supply geographically concentrated in a region with political or logistical risk? How long is the lead time, and how variable is it?

Once categories are scored and plotted, the matrix should be reviewed with stakeholders from procurement, engineering, operations, and finance to validate placements. A category that procurement views as low-risk may be assessed very differently by engineering if the item has a tight specification that only one supplier can reliably meet.

Moving items between quadrants

The Kraljic Matrix is not static. Procurement strategy should aim to move items toward more favorable positions over time. A bottleneck item can become non-critical if a second qualified supplier is developed and certified, eliminating the supply risk. A leverage item can become non-critical if the spend is consolidated into a framework agreement that removes the need for individual negotiations. A strategic item can shift toward leverage if the specification can be standardized to allow more suppliers to compete.

The matrix should be reviewed at least annually, or whenever a significant change occurs in the supply market (a supplier acquisition, a commodity price spike, a geopolitical disruption) or in the company’s product portfolio (a new product that introduces a new critical component, or a product discontinuation that removes a category).

Supplier segmentation beyond Kraljic

The Kraljic Matrix is the dominant framework but not the only one. Some organizations use a three-tier model (strategic partners, preferred suppliers, approved vendors) linked to a supplier development program that progressively elevates high-performing suppliers from approved to preferred to strategic status. Others add a third axis (supplier performance or financial stability) to create a three-dimensional segmentation that distinguishes between a high-risk strategic item sourced from a financially stable supplier and the same item sourced from a financially fragile one.

Regardless of the specific framework, the underlying principle is the same: not all suppliers deserve the same level of management attention, and misallocating that attention (over-managing low-risk relationships, under-managing high-risk ones) is both costly and dangerous.

Common errors in supplier segmentation

• Segmenting by supplier rather than by category. The Kraljic Matrix segments purchased categories, not individual suppliers. A single large supplier might provide both strategic components (requiring partnership management) and non-critical commodities (requiring only transactional efficiency). Treating that supplier uniformly in either direction misses the nuance.
• Letting spend data alone determine profit impact. A $200,000/year component that is the only part enabling a $50 million product line has far more profit impact than a $2 million/year commodity. Pure spend analysis without a conversation about operational criticality misclassifies many bottleneck items as non-critical.
• Not funding the risk mitigation actions the matrix implies. Placing a supplier in the bottleneck quadrant and then failing to fund the inventory buffer or the second-source qualification that the classification requires leaves the company exposed. The matrix is only useful if it drives resource allocation decisions.
• Treating the matrix as confidential from suppliers. Strategic and bottleneck suppliers who understand they are in a critical position for the buyer often respond constructively to transparent conversations about that relationship’s importance. Hiding the classification and then asking for partnership-level investment from the supplier without offering partnership-level commitment from the buyer creates mistrust.

Frequently asked questions

What is the Kraljic Matrix and how is it used in procurement?

The Kraljic Matrix is a supplier segmentation framework developed by Peter Kraljic in 1983 that classifies purchased items into four quadrants based on two dimensions: profit impact (how important the item is to the company’s financial performance) and supply risk (how difficult it is to source the item reliably). The four quadrants are strategic (high impact, high risk), leverage (high impact, low risk), bottleneck (low impact, high risk), and non-critical (low impact, low risk). Each quadrant requires a different procurement strategy: strategic items need collaborative partnerships and long-term contracts; leverage items call for competitive tendering and aggressive negotiation; bottleneck items require safety stock and backup supplier development; and non-critical items should be handled with automated, low-cost transactional processes. The matrix is used to prioritize procurement management effort and align buyer-supplier relationship investment with the actual risk and value at stake in each category.

What is the difference between strategic and leverage items in the Kraljic Matrix?

Both strategic and leverage items have high profit impact (they represent significant spend or are operationally critical), but they differ on supply risk. Strategic items have high supply risk: few qualified suppliers exist, switching is difficult or expensive, lead times are long, or the item is sourced from a proprietary or geographically concentrated source. Leverage items have low supply risk: multiple qualified suppliers can provide the item, switching costs are manageable, and the buyer can credibly threaten to change suppliers. The procurement strategy for strategic items is partnership and relationship investment; for leverage items, it is competitive leverage and price negotiation. In practice, the strategic-to-leverage transition is one of the most valuable moves a procurement team can make: if an engineering team can standardize a proprietary specification to allow competitive sourcing, a strategic item becomes a leverage item and the buyer gains significant bargaining power.

What is a bottleneck item and how should it be managed?

A bottleneck item is a purchased category with low profit impact (small share of total spend) but high supply risk (few sources, difficult to switch, long lead time, or proprietary specification). Classic examples include single-source regulatory compliance components, niche specialty materials, and proprietary maintenance parts for legacy equipment. Despite their low spend, bottleneck items can halt operations if supply fails, which makes their risk disproportionate to their cost. The management strategy for bottleneck items is risk mitigation: hold safety stock sized to cover the supplier’s lead time plus a disruption buffer; qualify at least one backup supplier even if that supplier carries a price premium; monitor the current supplier’s financial health and production capacity regularly; and negotiate supply assurance clauses (minimum production reservations, priority allocation commitments) into the contract. The cost of these mitigation actions is almost always less than the cost of a production stoppage caused by a bottleneck failure.

How do you determine the profit impact and supply risk of a purchased item?

Profit impact is determined by combining spend analysis with operational criticality assessment. Items with large spend as a percentage of COGS are clearly high-impact; items with small spend but high operational criticality (they enable a high-revenue product line or are a production gate item) should also be rated high-impact. Supply risk is determined by market analysis: how many qualified suppliers exist globally and in accessible markets? How long does supplier qualification take? Is the item a standard commodity or a proprietary specification? Is supply geographically concentrated in a politically or logistically risky region? What is the typical lead time and how variable is it? Scoring can be as simple as rating each dimension high or low based on qualitative judgment from procurement, engineering, and operations stakeholders, or as detailed as a weighted scoring model using five to ten sub-criteria per dimension. The value of the matrix comes from the strategic conversations it forces, not from the precision of the scoring.

How often should the Kraljic Matrix be updated?

The Kraljic Matrix should be reviewed at least annually as part of the procurement planning cycle. It should also be triggered for immediate review by any of the following events: a key supplier’s financial position deteriorates significantly; a supply market disruption changes the number of available sources or drives a major price shift; a new product introduction adds a new critical component that was not previously in the portfolio; an existing product is discontinued, removing categories from the portfolio; a geopolitical event (tariff changes, trade restrictions, regional conflict) materially changes the supply risk for a geographic cluster of suppliers; or a supplier merger or acquisition reduces the number of available sources in a category. Between formal reviews, procurement should monitor supply risk indicators for strategic and bottleneck items on an ongoing basis, since these are the categories where a rapid deterioration could cause operational disruption before the next scheduled review.

Can the Kraljic Matrix be used for services as well as goods?

Yes, the Kraljic Matrix applies to purchased services as well as physical goods, though the criteria for assessing profit impact and supply risk differ somewhat. For services, profit impact includes the cost of the service as a percentage of total spend, the revenue at risk if the service were unavailable, and the difficulty of replacing the service output internally. Supply risk includes the number of qualified service providers, the switching cost (which for complex services like IT outsourcing or contract manufacturing includes contractual exit costs, transition costs, and the time needed to transfer knowledge to a new provider), and any regulatory or certification requirements that limit the available supply base. Professional services, outsourced IT operations, and contract manufacturing are often in the strategic quadrant for companies that depend heavily on them. Facilities maintenance, security services, and standard cleaning or logistics contracts are typically in the leverage or non-critical quadrant.
