What is the SIS Matrix. It is derived from the Kraljic Matrix?
Kraljic Matrix, also known as Purchasing Portfolio Matrix or Supply Chain Portfolio Matrix, is a method developed by Peter Kraljic in 1983. It is used to create a purchasing portfolio by segmenting items (products or inventory or services) into 4 dimensions. The result is that purchasing professionals can prioritize buying activities based on profit impact and level of risks involved.
Over the years, the Kraljic model was extended and other dimensions are used to segment various issues under the supply chain environment. Over the years, the Kraljic model can be applied to the bidding and tendering process.
