Guide on Defect Density
Defect Density
Defect Density is a metric used in software development as a part of Scrum performance metrics. It is defined as the number of confirmed defects detected in software/component during a defined period of the development process.
Importance
The Defect Density metric is important as it helps to estimate the quality of the testing performed and gives an understanding of the quality of the software. This metric provides insight into the level of defects present in the product and helps to estimate project efficiency. It can be used as a benchmark for comparing the quality between different software or even different versions of the same software.
How it works
Defect Density is calculated by dividing the number of reported defects by the size of the software (in KLOC or FP).__The formula for defect density is:__
Defect Density = (Number of Defects / Size of the Software) * 1000
Exam Tips: Answering Questions on Defect Density
For exam questions on Defect Density, it's important to understand not only what Defect Density is but also how and why it is used. Be prepared to calculate Defect Density using the given software size and number of defects.
Also, be able to explain the importance and benefits of measuring Defect Density in a software development project.

Defect Density practice test
Defect Density is the number of defects confirmed for a certain size of the software deliverables (for example, per lines of code, per person-hour, or functional points). Low defect density signifies high product quality, while high defect density may indicate potential problems in product quality. Regularly tracking and addressing defect density can increase the quality of deliverables, improve team's productivity, and minimize technical debt.
