Overview

Enterprise business software is designed for particular applications but always runs in the context or environment of an overall business data processing system. Applications thus must be integrated by testing in an actual operating environment or a virtual test version of it. In some cases critical new software may be run in parallel to ensure that all situations are tested with real data. Successful applications software is often extended or upgraded to meet new application requirements. The new version must be tested for functionality, regression-tested for continuity, and integration-tested for conformity. Maintenance programmers often are less experienced than the team that wrote the software and thus must be well led and supplied with good tools. Taguchi Methods are well suited not only for software extension but also for software maintenance.
