Change Vector Tracking | Glossary

Definition:

Change Vector Tracking is a reflective approach towards desigining large scale software, a software engineering practice to achieve a high level of software design agility. This practice is iterative and reflective in nature and can be used to evaluate different design options with respect to the most important nonfunctional requirement.

Change in business requirements is the only constant in software development process. The key philosophy behind Change Vector Tracking is to identify and model this change as a vector and track it to make good refactoring decisions. The resulting software is less rigid and less fragile thus leading to lesser maintenance cost. This practice aids in Emergent design and is more suited for teams who have embraced Agile Software Development frameworks.

Qualification Testing | Glossary

Definition

Qualification Testing involves a formally defined series of tests that determine the functional, environmental and reliability of a component, or system. It is carried out to satisfy the engineer, contractor, or owner on the nature of its satisfactory design and construction, prior to final approval and acceptance.

The Production Qualification Testing is conducted at the unit, subsystem and system level and is completed before the decisions made for the production. The test results play a critical factor in determining the readiness for production of the system. Down Line Production Qualification Tests (PQTs) are performed to verify process control later on.
