Software quality metrics are a subset of software metrics that focus on the quality aspects of the product, process, and project. These are more closely associated with process and product metrics than

Product Quality Metrics

This metric includes the following −

• Mean Time to Failure: This metric is mostly used with safety critical systems such as the airline traffic control systems, avionics, and weapons.

• Defect Density: It measures code quality per unit.

• Customer Problems:It measures the problems that customers encounter when using the product.

• Customer Satisfaction:Customer satisfaction is often measured by customer survey data through the five-point scale −Very satisfied,Satisfied,Neutral,Dissatisfied,Very dissatisfied

In-process Quality Metrics:

In-process quality metrics deals with the tracking of defect arrival during formal machine testing for some organizations. This metric includes −

• Defect density during machine testing
• Defect arrival pattern during machine testing
• Phase-based defect removal pattern
• Defect removal effectiveness

Benefits:

Engineering metrics provide valuable benefits for organizations that develop software.

• They can help increase the overall quality of the product.
• They can increase team productivity.
• Metrics can even help you reduce costs by alerting you early on about problems that may show up in all stages of the software development life cycle.
