A decision matrix establishes a relationship between all possible situations of a project and the proposed alternative courses of action. The header of the matrix contains the relevant situations, the header column lists the alternative solutions, naturally excluding unsuitable combinations. The cells within the matrix now offer weighed consequences, which for each individual situation form the starting point of an evaluation and hierarchical arrangement of their alternative actions. This approach to decision making is appropriate when the various scenarios are manageable and the alternatives are equally valid. (Source: Gabler Management)
