In supply chain management, the Kraljic matrix (or Kraljic model) is a method used to segment the purchases or suppliers of a company by dividing them into four classes, based on the complexity (or risk) of the supply market (such as monopoly situations, barriers to entry, technological innovation) and the importance of the purchases or suppliers (determined by the impact that they have on the profitability of the company). This subdivision allows the company to define the optimal purchasing strategies for each of the four types of purchases or suppliers.
It is named after Peter Kraljic, who first formulated the model in an article called Purchasing Must Become Supply Management, published in the Harvard Business Review in 1983.
The Kraljic matrix defines the following types of articles:
In its original form, Kraljic's matrix is used for the mapping of purchases, not suppliers.
In its original form, KraljicâÂÂs matrix is used for the mapping of purchasing categories. However, the matrix is frequently misapplied to supplier segmentation rather than product or service segmentation, for which it was not designed. A single supplier may provide goods or services that span multiple quadrants of the matrix simultaneously, meaning any single classification of the supplier produces a misleading composite. This conflation of supplier with purchasing category can result in procurement strategies that are misaligned with actual supply risk and commercial opportunity.
A further limitation is that the matrix represents a static snapshot of supply market conditions at a point in time. KraljicâÂÂs original intent was to inform periodic strategic planning, not to provide a continuous classification system. Supply risk, market complexity, and spend profiles change over time, meaning a classification that was accurate at the time of analysis may become unreliable as conditions evolve. Organisations that treat Kraljic classifications as durable rather than provisional risk making sourcing decisions based on outdated assessments.
A third common source of misapplication arises when practitioners substitute expenditure for profit impact as the vertical axis. Substituting spend introduces a systematic bias, elevating high-volume, low-margin categories while understating the importance of lower-spend items that are critical to product quality, operational continuity, or competitive differentiation. This distortion compounds the supplier-versus-category conflation, producing classifications that reflect purchasing volume rather than genuine strategic importance.
