Effective time capturing is normally done against a Work Breakdown Structure (WBS). QTIME provides for up to nine levels of work breakdown structure.

Not all of these levels need be used, or even be hierarchical in nature. For example, an Activity may be related to a Project in a typical hierarchical relationship, where as a Cost Centre may also be a sub code to a Project, but may not be hierarchical. This would enable a single Cost Centre library to be used across all projects whereas the Activity library would be project specific.

The field names for the generic coding structure and the hierarchical links between codes are defined during the QTIME implementation process.

Drop down lists are used extensively throughout QTIME to simplify and ensure the consistency of data entry.
