In the
days of monolithic application systems, software evaluation and
selection used to be much simpler than in today's increasingly
integrated environment.
Today,
businesses are moving away from building or acquiring large,
monolithic application systems. Using a service-oriented application
design, application software is broken down into its constituent
parts, that is into smaller, more modular application components or
services. These application services make use of infrastructure
software that has also been decomposed into discrete system services.
All of these discrete services can be deployed across any number of
physical machines that are connected to the Internet. This modular
service approach provides great flexibility in terms of system
design.

The move towards service oriented architecture (SOA) has profound ramifications on how software should be evaluated and selected. In fact, software evaluation and selection in a SOA environment is quite different from how it used to be in the days of monolithic application systems, such as ERP packages. Dieter Jenz provides an outline of important aspects that should be considered in the software evaluation and selection process.

A Requirements Package (a.k.a. Requirement Templates Package) represents a comprehensive collection of requirements. The Evaluation Specification Editor (ESEdit) lets you quickly and easily import requirements from a Requirements Package using drag & drop. ESEdit is part of the Evaluator's Application Suite (EAS).
The Business Infrastructure Requirements Package is the largest Requirements Package and includes all other Requirement Packages. It pays tribute to the fact that modern service-oriented architectures demand a well-integrated business infrastructure, which provides basic services that multiple applications can make effective use of. Repository services, business process management services, business rules management services, and security services are just a few constituents of a modern business infrastructure.
This article explains how you can make effective use of the Business Infrastructure Requirements Package. Please read on to learn more about how you can dramatically cut down on the time needed to arrive at a well-authored Evaluation Specification.
