# Matrix management

The combined area of sets A and B is the union of A and B, as we discussed in the previous section. The main reason for using graphical symbols in this portion is to have an immediate visual indication of the distribution of the tasks among the engineers. Companies that have multiple business units and international operations, upon closer inspection may apply matrix structures in different ways.

## The Overlapping Set Equation

Filtering rows and columns by stereotype Instead of listing all elements with same type in row or column, you can fitler them further by selecting only elements with stereotype s assigned by listed. To fitler, move your mosue pointer over an assigned element type in the configuration screen. A matrix is a table with rows and columns, both represent sets of model elements of specific types.

A cell in table is an intersection of a row and a column which reflects the relationship of the row and column. If the cell is filled either by a tick or by a kind of relationship when a matrix was set to match things by Relationship , this means that the model elements of the row and column are related. The type of relationship can be checked by referring to the drop down menu at the top left of matrix.

You can export Excel file from matrix, and analyze relationships between model elements in worksheet in Excel.

Home Docs Chapter Matrix Diagram How to create a matrix for model analysis A matrix is a table, which shows the existence of relationships among model elements of particular types. Field Description Diagram Name The name of diagram which is also the name of matrix. The items in set A will appear on the half of the main column above the main row, while those of set B will be in the half below the main row.

The items of the common set C will appear on the main row. If the half-columns of sets A and B in the T-matrix described above are bent to allow inter-relation of items of set A to those of set B, then a Y-shaped matrix results. Placing two T-shaped matrices back-to-back, however, will result in an X-shaped matrix , which allows the inter-relation of four sets of items to each other. Lastly, the C-shaped matrix is a 3-dimensional matrix that interrelates three sets of elements simultaneously.

To construct a matrix diagram, the following steps are usually taken: As an example , suppose that a supervisor wants to document the assigned tasks and expertise levels of his engineers in matrix format. Since he needs to interrelate two different sets of information assignments and expertise levels to a third common set his engineers , then the T-shaped matrix is the best format for his purpose.

Also, in this case, he has all the information he needs to fill up the matrix, so no team is formed for the task. Had a more complex matrix been required, then the right people must be called in to form the matrix. Figure 1 shows the T-matrix for this example. Expertise Levels of 3 Engineers. Win Hindle, DEC sr.
