Ian Sommerville's research work, partly funded by the EPSRC [5] has included systems requirements engineering and system evolution. He defined the process of Construction by configuration (CbC). A major focus has been system dependability , including the use of social analysis techniques such as ethnography to better understand how people and ...
[1] [2] Some like software engineer and author Ian Sommerville don't use the term "quality control" (as quality control is often viewed as more a manufacturing term than a software development term), rather, linking its associated concepts with the concept of quality assurance. [3] However, the three core components otherwise remain the same.
Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the quality of ...

For sequential software, examples of formal methods include the B-Method, the specification languages used in automated theorem proving, RAISE, and the Z notation. In functional programming, property-based testing has allowed the mathematical specification and testing (if not exhaustive testing) of the expected behaviour of individual functions.
In addition to various implementations of static analysis, such as flow analysis, and unit testing, development testing also includes peer code review as a primary quality activity. Code review is widely considered one of the most effective defect detection and prevention methods in software development. [10]
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
Independent Software Verification and Validation (ISVV) is targeted at safety-critical software systems and aims to increase the quality of software products, thereby reducing risks and costs throughout the operational life of the software. The goal of ISVV is to provide assurance that software performs to the specified level of confidence and ...
