Describe Kraljic's Portfolio Matrix and explain its purpose, please consider the mentioned below and give an example Procurement managers must continually be aware of the supply and demand characteristics of the raw materials, component parts, and supplies they purchase. Kraljics Portfolio Matrix is used by many managers to classify corporate purchases in terms of their importance and supply complexity with a goal of minimizing supply vulnerability and getting the most out of the firms purchasing power. The matrix delineates four categories: 1. Non-Critical (low importance, low complexity), 2. Leverage (high importance, low complexity), 3. Strategic (high importance, high complexity), and 4. Bottleneck (low importance, high complexity). The key will be for procurement to work with other functional areas to identify the most appropriate segmentation dimensions for their firm. This segmentation should also be reviewed and updated on a regular basis..
