10.6.1 Problem Description

In this case study, assume that the system is an online
application that is processing transactions against a central
database used for accounts receivable.  The transactions
perform three basic functions: processing invoices, logging
credit updates, and making inquiries against open items.  The
organization tracks the volumes of each of these business
elements for management reporting in several divisions.

The objective of this case study is to investigate whether a
relationship exists between the three business elements and
the number of EXCPs required by the application.  If such a
relationship can be established, a business element model can
be generated and used to forecast future application resource
requirements.

This case study is based on a paper published by Sarna which
described an early effort at Business Element Forecasting
(SAR79).
