• Prioritization matrices. Identify the key issues and the suitable alternatives to be prioritized as a set of
decisions for implementation. Criteria are prioritized and weighted before being applied to all available
alternatives to obtain a mathematical score that ranks the options.
• Activity network diagrams. Previously known as arrow diagrams. They include both the AOA (Activity
on Arrow) and, most commonly used, AON (Activity on Node) formats of a network diagram. Activity
network diagrams are used with project scheduling methodologies such as program evaluation and
review technique (PERT), critical path method (CPM), and precedence diagramming method (PDM).
• Matrix diagrams. A quality management and control tool used to perform data analysis within the
organizational structure created in the matrix. The matrix diagram seeks to show the strength of
relationships between factors, causes, and objectives that exist between the rows and columns that form
the matrix.
