A software reliability growth model is one of the fundamental technique to assess software reliability quantitatively. The software reliability growth model is required to have a good performance in terms of goodness-of-fit, predictability, and so forth. In this paper, we propose dis-cretized software reliability growth models. As to the software reliability growth modeling, discretized nonhomo...

Due to the critical challenges and complexity of modern software systems developed over the last decade, there has arisen an ever increasing attention to look for products with high reliability at reasonable costs. Software development process moves toward component-based design, and architecture based approach in software reliability modeling is widely used. However, in lots of models for soft...

This entry identifies the factors that control software reliability and the approaches that are needed to achieve desired reliability targets. Common reliability measures are defined. The factors that impact defect density and defect finding rates are discussed and software reliability growth modeling is introduced. Both test-timeand test-coverage-based models are introduced. Modeling for secur...

Software reliability deals with behaviour of a software system in operation and it is defined as the probability of working without failure for a specified interval of time. In a number of recent disasters the computer has been wholly or partially to blame. In Ref. [1] an alarm signal is given by the following message: "Sometime soon, software reliability is going to become a highly visible and...

The IEEE defines reliability as “The ability of a system or component to perform its required functions under stated conditions for a specified period of time.” 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. While finding and fixing bugs discovered in testing is necessary to assure...

Black box reliability analysis (P. 111): Estimation of the software reliability based on failure observations from testing or operation. These approaches are called black box approaches because internal details of the software are not considered. Software metric based reliability analysis (P. 115): Reliability evaluation based on the static analysis of the software (e.g., lines of code, number ...

SOFTWARE-INTENSIVE SYSTEMS with high reliability requirements typically are implemented through heroic (and expensive) engineering efforts. Control systems in planes, nuclear reactors, trains, pacemakers, and spaceships are developed by highly trained personnel through strictly managed software development processes with a dose of formal methods. This approach has worked admirably up to now, bu...

Despite the increased importance of the role that reliability plays in commercial product development, most companies are still unable to produce reliable software. The practice of software reliability is rare with few techniques that are compatible with commercial schedules and staffing capabilities. Should organizations wait for the next generation of tools, programming languages and developm...

Testing is the process of executing a program with the intention of finding design errors in a given environment. Testing can only prove the incorrectness of software but not its correctness. Some people have argued that testing is useless because what we want is the correctness of software instead of its incorrectness. This idea has led to the research of techniques for developing correct soft...
