Managers are always interested in asking questions like this one about the project DOORS requirements management database: ”How many of these kinds of requirements do we have now?” Options for providing an answer include creating custom views or developing DXL scripts in DOORS.
However, another alternative is to provide on-demand metrics data. It is straightforward to create module level DXL attributes that can provide desired data, equivalent to running a simple or compound filter query in DOORS. This data is pulled into a master module called the Module of Metrics (MoM), which is accessible at any time by any DOORS user. Several examples of these DXL attributes are shown, as well as the DXL code to display the data in the MoM module. Minimal knowledge of DXL scripting is needed to modify the DXL attributes or to create new ones. The MoM approach can provide desired metrics data during the rapid adaptation of proven systems.
