PMP credential holders need to know that matrixes is not always used as diagrams. When studying matrix diagrams, you should be able to identify the type (L-shaped, Y-shaped, C-shaped, T-shaped, X-shaped, and roof-shaped ), when that type is used (how many data sets), and potential applications ( identifying root causes, comparing solutions, matching requirements with specifications ). Project Managers can use a matrix to analyze information of many types, for example: The uses of the matrix diagram for the PMP are the same as these examples of the tool from a Six Sigma process perspective : The matrix diagram for the PMP credential holder is defined in the 6th edition of the Project Management Body of Knowledge® ( PMBOK® Guide ), page 284. On the PMP exam, it is a tool to better understand the variables in a relationship in which data is available and decisions are needed. Matrix Diagrams in context of the PMP exam ”Īs seen in the provided examples, the matrix diagram tool can depict complex interrelationships among data sets with one, two, or three sets of variables. For all types of matrix, the project manager can “ easily visualize the relationship between objectives, factors, and causes within the organization they are observing. The number of elements being compared will determine which of the six matrix diagrams to use: L-shaped, Y-shaped, C-shaped, T-shaped, X-shaped, and roof-shaped. The project manager who earns their PMP should know the process behind matrix diagrams to maximize the use of this quality tool. Yet that software does not tell the PMP credential holder what the diagram means nor how to interpret the data. Software is available to create matrix diagrams based on the system’s evaluation of the data submitted. The Six Sigma Study Guide is just one place where the process for matrix diagram creation is provided: To create quality matrix diagrams, PMP credential holders need to know the process behind this planning tool. It is important to note matrix diagrams may also be called a matrix or matrix chart. The American Society for Quality describes the quality matrix diagram as a tool used for analyzing and displaying the relationship between two, three, or four groups of information. Patterns emerge organically and should not be forced. In this example of a matrix diagram, note the placement of data in cells as organized into rows and columns. The matrix diagram is a planning and decision-making tool that can be used in any industry. The power of the matrix diagram is showing not only the relationship between variables but the strength of that relationship.
