Defect Management

This course covers issues such as the quality of requirements, causes of defects, defect multiplication effect, defect and risk relation, and the importance of defect classification.
Code: SQA-024
Duration: 8 hours


Our training is useful for all project team members because defect management concerns everyone involved in software development, irrespective of their role or expertise.

We will discuss defect definitions and their relation with verification and validation, formulate criteria for high quality requirements, and illustrate difficulties in meeting them. We will look at a classification of defects based on the place of their occurrence at the stage of requirements description, compiling requirements specification, change requests, in architecture, code, or testing scenarios. Internal and external causes of these defects will be reviewed.

Furthermore, well cover defect propagation (multiplication) due to untimely discovery and correction of defects as well as outlining defect management tasks. The approaches to building different classifications of defects will also be discussed.

In the course you will analyze testing types classifications based on the Rational Unified Process methodology as well as the specifics of documentation defects. Well consider examples of various defect life cycles and analyze their application depending on project specifics. You will learn about the purpose of a defect database and how to use it correctly plus get recommendations on defect description.
