Computerized systems allow us to easily incorporate a hierarchical structure in our projects as well as information within these projects. PCM allows for multiple hierarchies that can be easily switched. Hierarchical structures allow us to organize our projects at different levels. They also allow us to provide roll-up reporting at the various levels. Look at the following hierarchical structure:
You can see that security would be important at the various levels of the structure.
