Construction by Configuration (CbC)
[Sommerville Ian (2008)]
Construction by Configuration: Challenges for Software Engineering. Research and Practice.
St Andrews, Scotland. is a process defined by
Ian Sommerville in 2008 for the adoption of a Commercial off-the-shelf systems (COTS) in an organization. This can range from simple parameter setting through the definition of business rules to special purpose components development.
According to Sommerville, many companies and government organizations have changed their strategy from "specify and develop" to "buy and configure." Thus, generic systems are purchased and configured to create a specific version applied to an organization context by adapting modules to structures, business lines and processes.
In his work, Sommerville identified three (3) types of configurable systems: single PC-based applications with built-in, modular generic systems (such as
ERP systems) and COTS assemblies. He determined that the most complex and risky to configure are the COTS, and indicated that regardless of the facilities that this software category provides, a set of activities that are common in the configuration process should be managed to address avoid the mostly failures reported. These are:
# System selection.
# Requirements analysis.
#Business process redesign.

System configuration A system configuration (SC) in systems engineering defines the computers, processes, and devices that compose the system and its boundary. More generally, the system configuration is the specific definition of the elements that define and/or prescri ...

System testing
System testing is testing conducted on a complete integrated system to evaluate the system's compliance with its specified requirements.
System testing takes, as its input, all of the integrated components that have passed integration testing. ...
