===Processes===
IfcProcess is the base class for processes and is subdivided into tasks, events, and procedures.  Processes may have durations and be scheduled to occur at specific time periods.  Processes may be sequenced such that a successor task may start after a predecessor task finishes, following the [[Critical Path Method]].  Processes may be nested into sub-processes for summary roll-up.  Processes may be assigned to products indicating the output produced by the work performed.
