Pattern Deviation
Recognize problems in real-time.
Pattern deviation is the recognition when an activity is out of
bounds of expected behavior. It might be acceptable and early intervention
could ascertain appropriate remedies.
The middle curve represents the historical spending pattern
of an activity. The upper curve represents an activity that is high cost.
The low curve represents an activity that is probably behind schedule.
The middle curve is part of a zone of confidence. As long as real-time expenses fall within the cost / time parameters of the zone, normal project management practices are applied. When the progress of an activity, as outlined in the upper or lower curve occurs, then notification is initiated.
