The Kraljic matrix: How to segment suppliers strategically

Many procurement teams treat all purchasing decisions as roughly the same kind of problem. They run the same competitive bid process, manage every supplier relationship the same way, and apply the same level of scrutiny to a box of pens and a mission-critical component.

That approach wastes time on purchases that don't matter and gives inadequate attention to the ones that do.

In 1983, Peter Kraljic published a procurement framework in the Harvard Business Review that changed how organizations think about their purchasing portfolios. Procurement professionals still use it today because the core insight holds: not all spend is equal. Segmenting spend by strategic importance is a prerequisite for managing it well.

This guide covers what the Kraljic matrix is, how the four quadrants work, how to apply it in practice, and where it has limitations.

What is the Kraljic matrix?

The Kraljic Matrix is a strategic tool for categorizing purchases into four quadrants based on two variables: profit impact and supply risk.

Its purpose is practical: it helps procurement teams prioritize strategies, supplier relationships, and risk mitigation across a complex portfolio. Rather than managing every category with the same playbook, the matrix gives you a framework for deciding where to invest deeply and where to automate.

What makes it endure is its relevance to modern procurement challenges. Four decades of supply chain disruptions, cost pressure, and digital transformation haven't changed the fundamental truth it captures: the way you manage a commodity order should be nothing like the way you manage a critical single-source component.

The 2 axes of the Kraljic matrix

With the Kraljic matrix, every item in your purchasing portfolio can be scored on two dimensions:

1. Profit impact (vertical axis)

How significantly does this category affect profitability? High-impact categories carry large spend, tie directly to revenue or product quality, and have downstream consequences if supply is interrupted.

Low-impact categories are peripheral. They matter, but their absence doesn't threaten operations.

2. Supply risk (horizontal axis)

How difficult or risky is it to source this reliably? High-risk categories have few qualified suppliers, long lead times, or high switching costs. Low-risk categories have many available suppliers and easy substitution options.

The key insight is that these dimensions are independent. A category can be high profit impact and low supply risk—that puts it in the leverage quadrant. Or it can be low profit impact and high supply risk—that's a bottleneck item that demands very different handling.

The 4 quadrants of the Kraljic matrix

The matrix divides your entire supply base into four quadrants based on the two axes: how much a category affects your bottom line (profit impact) and how difficult it would be to secure supply if something went wrong (supply risk). Where a category lands determines how much strategic attention it deserves, and what kind.

1. Strategic items: High profit impact, high supply risk

These are your most critical purchases. They carry significant spend, few reliable alternatives exist, and operational disruption is a real consequence if supply is cut off.

Examples include:

• Raw materials or commodities with single-source constraints

• Proprietary or patented components

• Specialized manufacturing services

• Technology and infrastructure

• Energy inputs for industrial operations

• Professional and knowledge services

These aren't interchangeable, and your business is genuinely dependent on specific suppliers.

The right strategy here is relationship-building, not price-squeezing. Long-term partnerships, joint product development, dual sourcing where possible, and deep investment in the relationship all apply. These suppliers deserve your chief procurement officer’s (CPO's) attention.

2. Leverage items: High profit impact, low supply risk

These are high-value categories where you hold the negotiating power. Significant spend is involved, but the market has abundant supplier options, which means you can push for better pricing and terms without risking supply continuity.

Examples include:

• Commodity raw materials

• Standard industrial components

• Widely available professional services

The goal is to extract maximum value through competitive bidding, multi-supplier sourcing, and volume aggregation.

Amazon Business is built for this quadrant. For leverage and non-critical items — categories where competitive selection, price comparison, and efficient ordering drive real savings — a platform that connects you to millions of business sellers at transparent prices does exactly what the strategy calls for.

3. Bottleneck items: Low profit impact, high supply risk

Low-spend categories with outsized operational risk. The dollar amounts aren't large, but the supply situation is precarious: few qualified suppliers, specialized production requirements, or long lead times that make substitution difficult.

Examples include:

• Spare parts for aging or discontinued equipment

• Specialized filtration media for a regulated process

• Niche fasteners or seals with tight tolerances

• Single-source MRO items where the OEM is the only qualified supplier

• Certain food-grade additives with long lead times and few approved vendors

• Custom molds or tooling held by one supplier

The strategy here is risk mitigation: safety stock to buffer against disruptions, developing alternative qualified suppliers, and long-term supply agreements that prioritize availability over price.

4. Non-critical items: Low profit impact, low supply risk

Routine purchases with minimal strategic importance and easy substitution. These purchases need to happen reliably, but they don't require active management.

Examples include:

• Office supplies

• Standard cleaning products

• Safety PPE (gloves, glasses, vests) from widely available sources

• Breakroom consumables

• USB cables and basic peripherals; batteries

The right approach is to standardize and automate. Catalog purchasing, preferred supplier programs, and digital buying platforms all reduce the time your team spends on decisions that don't require strategic thinking.

How to apply the Kraljic matrix

The Kraljic matrix helps procurement leaders align sourcing strategy with business risk and value creation. Applying it effectively typically follows four steps:

Step 1: Build a clean spend baseline

Start with a structured spend analysis that gives you a complete view of your purchasing. That view can come from consolidating data across enterprise resource planning (ERP), accounts payable (AP), and sourcing systems, or from spend analytics dashboards that surface the same insight directly. The goal is not just visibility, but category-level clarity:

• What is being purchased (standardized categories, not fragmented line items)

• Who the suppliers are (including concentration risk)

• Total spend and contract coverage

• Demand variability and business criticality

For leaders, this step often surfaces a key insight: most organizations lack a single source of truth for spend. Without this, downstream segmentation becomes unreliable. Modern spend analytics and AP automation platforms can accelerate this step by enriching and normalizing data automatically.

Step 2: Quantify profit impact and supply risk

Move beyond subjective scoring by defining measurable criteria for both axes:

• Profit impact: Annual spend, margin sensitivity, revenue dependency, customer impact of failure

• Supply risk: Supplier concentration, geographic risk exposure, lead time variability, switching cost, regulatory constraints

A simple scoring model (e.g., a 1–5 scale) works well, but leading teams increasingly augment this with external market intelligence (commodity indices, supplier financial health, geopolitical risk signals). For example, a cloud contact center platform may have moderate spend but extremely high operational impact, pushing it toward “strategic” despite not being the largest category.

Step 3: Segment categories and identify priority zones

Plot categories into the four quadrants, but focus less on perfect placement and more on decision relevance:

• Strategic (high impact, high risk)

• Leverage (high impact, low risk)

• Bottleneck (low impact, high risk)

• Non-critical (low impact, low risk)

In practice, a relatively small number of categories often account for most procurement risk and value, which is why teams use the Kraljic matrix to prioritize attention and resources.

Borderline categories are useful signals—they often indicate areas where supplier markets are shifting or where internal demand is evolving.

Step 4: Align sourcing and technology strategy

The real value of the Kraljic Matrix is in differentiated action, not classification. The next step is to look at how procurement strategy changes by quadrant.

• Strategic: Invest in supplier partnerships, innovation, and performance management

• Leverage: Drive competition, optimize pricing, and consolidate spend

• Bottleneck: Mitigate risk through inventory buffers or supplier development

• Non-critical: Automate procurement and streamline transactions

For procurement leaders evaluating technology, this step becomes critical. Different quadrants map directly to different capabilities:

• Strategic: Supplier collaboration platforms, performance analytics, risk monitoring tools

• Leverage: eSourcing, benchmarking tools, contract lifecycle management

• Bottleneck: Supplier risk intelligence, scenario planning tools

• Non-critical: AP automation, intake-to-procure orchestration, catalog buying

According to Deloitte’s 2025 CPO Survey, organizations allocating around 24% of their budget to procurement technology achieve nearly 3.2x ROI. The Kraljic framework helps ensure that investment is targeted, rather than spread thinly across low-impact areas.

Limitations of the Kraljic matrix

The matrix is a powerful tool, but it has real constraints worth understanding.

It simplifies complex reality

Real supply relationships rarely sit cleanly in one quadrant. A supplier that delivers a leverage item can also be your strategic partner for a bottleneck component and the same vendor may require different treatment for different categories.

It's a snapshot, not a system

Supply risk and profit impact shift as markets change. A category that was non-critical two years ago can become a bottleneck item after a supply chain disruption or regulatory change. According to McKinsey's 2024 supply chain risk research, nine in ten companies encountered supply chain challenges in 2024. A matrix you build once and never revisit will lead you wrong.

It identifies strategy, but it doesn't execute it

The matrix tells you what approach each category deserves. Closing the gap between framework and action requires the right tools: spend analysis, supplier management systems, and buying platforms that let you execute at scale.

For strategic and bottleneck item management, that often means supplier relationship management programs and dedicated supplier risk management workflows. For leverage and non-critical items, it means platforms that make competitive purchasing fast and consistent.

Strategy starts with knowing what you're buying

The Kraljic Matrix is a lens. It helps you make better decisions about where to invest time, build relationships, and manage costs, not by applying one strategy to everything, but by recognizing that different categories of spend require fundamentally different approaches.

That insight is as useful today as it was in 1983 when Kraljic published it. What's changed is the tooling: where classifying spend once meant manual analysis of static reports, procurement teams can now pull real-time spend data, automate approvals, and act on category insights from a single platform.

Amazon Business gives procurement leaders visibility into spend across categories, approval workflows to enforce buying policies, and a buying platform that's built for the way leverage and non-critical item purchasing actually works. It's the execution layer that turns a framework into action.
