Time Variant data requires an insightful analyst to intelligently leverage
its connections and correlations.

Exception Reporting may be the use of Time Variant data that delivers
the highest ROI. A data warehouse can be used to monitor enterprise
and customer behaviors across extended periods of time. When those
enterprise or customer behaviors change, to the point of being excep-
tional, a BI Report can be written to notice such exceptions. When these
exceptions occur, that same report can be written to find the enterprise
objects, properties, or attributes that changed prior to the exceptional
behavior. If the enterprise and customer behaviors never changed, such
a report would remain empty. However, when exceptional behavior
occurs, such a report would notice the exception and the difference in
enterprise objects, properties, and attributes that preceded the excep-
tional behavior.
Such a r eporting mechanism is helpful when exceptional behavior is
expected as well as when exceptional behavior is not expected. Either way,
an exception report that leverages Time Variant data allows the users of a
data warehouse to notice changes in the behaviors of the enterprise and its
customers and the changes in the enterprise that preceded them. The ROI
of Time Variant data is the ability to correlate changes in the behaviors of
the enterprise or its customers and preceding changes in the enterprise.
