Operations Decide

Kraljic Matrix

The Kraljic matrix sets a purchasing posture from profit impact and supply risk: routine, leverage, bottleneck, or strategic.

The questionFor each thing we buy, how much does it matter to profit and how hard is it to secure, and so how should we buy it?

Kraljic purchasing portfolio model. The low-impact, low-risk group is called non-critical in the original and routine in much later usage.

Large share of cost Profit impact Small share of cost

Leverage Press on price and run competitive bids.

Strategic Build partnerships and secure long-term supply.

Non-critical Simplify and automate the buying.

Bottleneck Secure supply first, then look for alternatives.

Many suppliers Supply risk Few suppliers

Each purchased category lands in one quadrant, and each quadrant has its own buying posture.

When to use it

Procurement runs the same tender and spend review for every category, and negotiating time is spread evenly across items that matter very differently.
A spend analysis shows hundreds of categories, and the team has no way to decide which ones deserve senior attention.
A shortage of a cheap, single-source part has stopped production, and the client wants to find the other parts like it.
A cost-reduction program is pushing price on suppliers that the business cannot easily replace.

When to avoid it

There are only a handful of categories and the team already knows which ones matter. A short conversation will do the same job.
The question is about a supplier relationship rather than a category. One supplier often provides items in several quadrants, and a single label for it misleads.
The decision is how much of an item to order and how often. That is a sizing question, and the Economic Order Quantity is the tool.
Supply risk needs a proper exposure analysis, such as a country or single-plant dependency. A two-by-two score hides how large and how likely the risk is.

Overview

The Kraljic matrix sorts purchased categories by two questions: how much the category affects profit, and how hard supply is to secure. Each of the four resulting groups gets a different buying posture, from minimizing effort to forming long-term partnerships. It supports the choice of where procurement should spend scarce negotiating and relationship time.

It classifies what is bought, not who sells it. A supplier that provides several categories can sit in several quadrants, and using spend as a stand-in for profit impact pushes high-volume, low-margin items to the top. The placement is also a snapshot. A category that is easy to source today can become a bottleneck when a supplier exits.

The four categories

Non-critical (routine)

Low profit impact and low supply risk. Many suppliers, easy substitution, small value. The posture is to spend as little buying effort as possible, by standardizing, consolidating suppliers, and using catalogs or delegated ordering. Savings come from process cost, not price.

Leverage

High profit impact and low supply risk. The category matters, and the market has many capable suppliers. The posture is to use buying power, through competitive tendering, volume consolidation, and willingness to switch. This is where price pressure pays.

Bottleneck

Low profit impact and high supply risk. The value is small, but few suppliers exist, or switching is slow, so a failure can halt production. The posture is to secure supply, even at a premium, by qualifying a second source, holding buffer stock, or redesigning to remove the dependence.

Strategic

High profit impact and high supply risk. The category drives profit or product quality, and the supply market is thin or concentrated. The posture is a long-term relationship, with joint planning, close monitoring of the supplier and the market, and a deliberate make-or-buy view.

What it is not

A supplier segmentation tool. The matrix classifies what is bought, and one supplier can supply items in several quadrants at once.
A ranking by spend. Using spend as a stand-in for profit impact raises high-volume, low-margin items and hides cheap items that stop production or damage quality.

The steps

List categories, not suppliers

Group spend by what is bought. If a single supplier covers several categories, split the supplier across them. What comes out is one list with an owner for each line.
Score profit impact

Ask how much the category contributes to cost of goods, how it affects product quality or revenue, and what a disruption would cost. Do not use spend alone. A cheap item can carry a very large impact.
Score supply risk

Ask how many qualified suppliers exist, how hard substitution is, how concentrated the market is, and how long it takes to switch. Include people from engineering and operations, because purchasing alone rarely sees the technical lock-in.
Plot it and challenge the borderline cases

Place each category on the grid and test the ones near a line with the people who use them. Write down what would move a category from one box to another.
Set the posture, owner, and review date

Give each category its posture, a named owner, and the first action, such as tender, qualify a second source, or move to a catalog. Set a date to plot again.

In practice

The CFO has asked procurement for five percent off all spend, applied evenly. A food manufacturer's category team places its forty or so categories before agreeing. Corrugated cartons are high in spend and have many suppliers, so they are leverage. Janitorial supplies and uniforms are non-critical. A specialty flavor ingredient costs little but comes from one supplier in one region, and no flavor means no product, so it is a bottleneck. The main protein ingredient defines product quality and has only a few qualified suppliers, so it is strategic.

The even five percent would have landed hardest on the two suppliers the business can least afford to lose. The consultant proposes a different plan: tender cartons annually, move non-critical items to a catalog with one supplier, qualify a second flavor source and build twelve weeks of stock in the meantime, and open multi-year agreements with shared forecasts on the protein. The CFO's target is met from cartons and catalog consolidation.

What you leave with

A category list with both scores and a one-line reason behind each.
A grid with every category placed, and the borderline ones marked.
A buying posture and a named owner for each category.
A short list of first actions, split into tender, secure, standardize, and partner.
A review date, and the events that would trigger an earlier re-plot.

Failure points

Spend standing in for profit impact

The easiest data to pull is annual spend, so it quietly replaces the vertical axis. The plot then shows what is expensive. A cheap bottleneck part that can stop a plant stays in the corner as non-critical.

Scores set by purchasing alone

Purchasing rates supply risk without engineering or operations, and misses design lock-in, qualification lead times, and single-plant dependence. The risk axis ends up measuring how hard buying is, not how hard supply is.

The supplier as the unit

A supplier is placed in one box as a whole. Its leverage items get strategic treatment, or its strategic items get squeezed, because the category-level view was lost.

Leverage tactics on strategic items

A harsh tender or a price demand is applied to a supplier the business depends on. A supplier squeezed on price has little reason to put this customer first when material is short, so the savings can be paid back in shortages.

A plot made once

Categories move. A supplier exits, a substitute appears, or a design change creates a new dependency. The plot from last year drives this year's sourcing, and the matrix is a snapshot, not a standing classification.

The failures above are usually Framing: the wrong problem was chosen before this framework was applied.

Origin

Peter Kraljic published the model in Harvard Business Review in 1983, in the article "Purchasing Must Become Supply Management." The article argued that resource scarcity, political turbulence, government intervention in supply markets, and fast technical change had ended the days of no surprises for purchasing departments, and that buying needed to be run as supply strategy. The matrix was the tool for deciding which purchases deserved that effort.

The original names the four groups non-critical, leverage, bottleneck, and strategic. Many later authors and practitioners call the first group routine. The matrix is not licensed and carries no trademark. Later academics and consultants have proposed changes, mostly to how the two axes are scored. In the original, the unit being classified is the purchased item or category, not the supplier.
