Matrisikaavio

Matrisikaavio is a Finnish term that translates to "matrix diagram" or "matrix chart" in English. It is a graphical tool used for displaying and analyzing the relationships between two or more sets of items. Typically, a matrix diagram is presented in a grid format where rows and columns represent different categories or variables. The intersections of the rows and columns are used to indicate the presence, absence, or strength of a relationship between the corresponding items.

The primary purpose of a matrisikaavio is to organize information and identify patterns or connections that might not be obvious in other formats. It is often employed in quality management, problem-solving, and decision-making processes. For example, a matrisikaavio could be used to map customer requirements against product features, or to analyze the causes of a problem against the potential solutions. The strength of the relationship is usually denoted by symbols or numerical values within the cells of the matrix.

Several types of matrix diagrams exist, differentiated by the number of sets of items they relate. Common forms include L-type matrices (relating two sets), T-type (relating three sets), Y-type (relating three sets in a branched manner), and X-type (relating four sets in a circular fashion). The choice of matrix type depends on the complexity of the relationships being analyzed. The clarity and effectiveness of a matrisikaavio depend on careful definition of the categories and consistent application of the rating system.
