The final BPE step—construction and integration focuses on implementation
detail. The architecture and infrastructure are implemented by constructing an
appropriate database and internal data structures, by building applications using
software components, and by selecting appropriate elements of a technology infra-
structure to support the design created during BSD. Each of these system compo-
nents must then be integrated to form a complete information system or application.
The integration activity also places the new information system into the business
area context, performing all user training and logistics support to achieve a smooth
transition. 4

10.4 PRODUCT ENGINEERING: AN OVERVIEW
The goal of product engineering is to translate the customer’s desire for a set of defined
capabilities into a working product. To achieve this goal, product engineering—like

4 It should be noted that the terminology (adapted from [MAR90]) used in Figure 10.2 is associated
with information engineering, the predecessor of modern BPE. However, the area of focus
implied by each activity noted is addressed by all who consider the subject.
