Defect Management Test Planning & Management

Defect Metrics | Severity, Density, Removal, Leakage, Cost and Age

In software testing, it is most important to measure the quality, cost and effectiveness of the project and the processes. Without measuring these, project can’t be completed successfully. The goal of testing is to determine if the requirements are met. During the course of testing, we find defects, or instances where the software does not meet requirements. Hence, in the area of software testing metrics, there has been abundant work in analyzing defects via different Defect metrics.

Defect Life Cycle
Defect Management

Everything has a Life cycle, even a Bug or a Defect!

Everything has a lifecycle – it’s the law of nature, a series of changes in form that an organism undergoes, returning to the starting state. Birth >> Infancy >> Childhood >> Teenage >> Adult >> Mature >> Old age >> Dead end. A ‘Defect’ in Software Testing also follows a pre-defined stage transitions from its identification till its closure. In Software Testing terms, we call it as ‘Defect Status transition’ or a ‘Defect Lifecycle’!
