Software reliability signifies the probability that software in a pre-defined condition executes its tasks without malfunctioning for a specified duration. It may be regarded as a component of software quality. Unlike software quality, however, it concentrates on the functionality of the software and disregards such issues as ergonomics of software products, development economics, etc. unless they constitute functional attributes of the software product. To most project and software development managers, reliability is equated to correctness, that is, they look to testing and the number of "Bugs" found and fixed.
