It is the degree to which a software product meets the gathered requirements. S

It is a set of activities that define and assess the adequacy of software process to provide evidence which establishes confidence that the software processes are appropriate for and produce software products of suitable quality for their intended processes

Software developers and their organizations rely on this. Software bugs can have immediate impacts on clients or customers.

Poor quality software tendsto be expensive to develop and maintain, which can negatively affect organizations or end up maintaining the software in the longer term. These costs are often referred to as “technical debt.”

The development and use of the software might require some form of certification, which can often require evidence of the application of various quality control and assessment measures.

There may be overriding legal obligations that apply to organizations that use the software. As such, every practicable measure must be taken to demonstrate that the software system does not pose a risk to its users.

In cases where a software system is not covered by software certification and legislation, and where its failure is not necessarily business or safety-critical, there can remain moral obligation to the users. This implies that software engineers should do whatever is possible to maximize the quality of their software and to prevent it from containing potentially harmful bugs.

Refers to building software application prototypes which displays the functionality of the product under development, but may not actually hold the exact logic of the original software. A prototype moves the quality assurance earlier and makes it easier.

This is a relatively fast method of prototyping that focuses on employing prototypes to generate insights about the software design idea. The created prototypes on this paradigm are discarded after testing and after obtaining feedback. This is used in early design stages where the gathered requirements are still unclear

The prototypes on this paradigm are reused after the testing in a way that they are altered according to the test results and then reused in a new test cycle. This evolves to become the end product itself. This is usually used in late development stages where sufficient insides about principle design decisions exist and the prototype addresses technical and long-term use issues.
