1. Purchasing Portfolio Matrix
I believe lots of people have seen this method many times but only few people know the origin. In 1983, Peter Kraljic wrote the article "Purchasing Must Become Supply Management" for Harvard Business Review. In this article, he proposed the way to create a purchasing strategy based on different types of commodity. Later, this method is known as "Kraljic Matrix" or "Purchasing Portfolio Matrix".
The idea is to create the custom strategy based on each type of commodity. Doing this way, purchasing can pay attention to problem areas such as strategic items and bottleneck items and try to automate/decentralize the process for non-critical items.
2. Demand Profiling Matrix

3. Fisher's Matrix for Product/Strategy

4. Global Supply Chain Matrix

6. Customer Window Quadrant

7. Supply Chain Security Matrix
The world is more complex than it used to be and the security has become the new burden for every trading partner in supply chain. In order to avoid potential delay from security screening, supply chain security program is necessary. In 2007, World Customs Journal published the paper called "Voluntary Supply Chain Security Program Impacts: An Empirical Study with BASC Member Companies". Again, a 2x2 Matrix has been used to prioritize various security measure in terms of cost and effectiveness.
