Best Quality Data: How much money do they owe us?
The first business process subject area you build should be the one with the most bang for
the buck. It should simultaneously answer the most important business questions and
be the most accessible from a data extraction point of view. A great place to start in most
enterprises is to model the process consisting of customer invoices or monthly statements,
as shown in Figure€7-1. This data source is probably fairly accessible and of fairly high
quality. One of Kimball’s laws is that the best data source in any enterprise is the record
of “how much money they owe us.” (page 211)
