A system for assigning human resources to service tasks. A long term forecasting module enables one or more users simultaneously working on that module to assign tasks that should be fulfilled in the each specific region, based on analysis of past demand and actual service operations. A mid-term planning module enables one or more users simultaneously working on that module to roughly allocate resources to fulfill actual future tasks and expected task demands. A short-term scheduling module enables one or more users simultaneously working on that module to roughly allocate specific human resources to fulfill actual tasks. A coordination module immediately propagates any change in the parameters of the human resource assignments resulting at any one of the forecasting, planning or scheduling modules to effect the other two modules. An analyzing module repeatedly checks the assignment actual status upon any introduction of an assignment update by the forecasting and planning modules to detect discrepancies and to generate alerts to correct those discrepancies.

The invention provides a technique for managing multiple contextual views of source code files. In a file system, different tasks demand that source code files be grouped in different hierarchical directories. When some or all of this manipulation is of the physical files themselves, the directories can become confused, and it may be difficult for the next user to access needed source code files. In the technique of the invention, the physical location of the files is independent of all contextual views, and is maintained in a separate viewable hierarchy. All items in contextual view hierarchies contain only references to the physical location of the source code files, and so modifications of those items, such as delete, move and copy, only alter the references themselves. A separate set of operations can be used for explicitly maintaining or modifying the physical source code files.
