QA Testing Introduction:
Quality assurance testing is any systematic process of checking to see whether a product or a service that being developed is meeting specified requirements. Many companies have a separate department devoted to the quality assurance. A quality assurance system is said to increase customer confidence & a company’s credibility, to improve work processes to enable a company to better compete with others.
Overview Of QA Testing Job Support:
Quality assurance is a way of preventing mistakes or defects in manufactured products & avoiding problems when delivering solutions or services to customers, which ISO 9000 defines as part of quality management focused on providing confidence that quality requirements will be fulfilled. This defect prevention in quality assurance differs subtly from defect detection & rejection in quality control and has been referred to as a shift left as it focuses on quality earlier in the process.
The terms quality assurance & quality control are often used to interchangeably to refer to ways of ensuring the quality of a service or product. For instance, the term “assurance” is often used as follows: Implementation of inspection & structured testing as a measure of quality assurance in a television set software project at Philips Semiconductors is described. The term “control”, however, is used to describe the fifth phase of the DMAIC model. DMAIC is a data-driven quality strategy used to improve processes.
Quality assurance comprises administrative & procedural activities implemented in a quality system so that requirements & goals for a product, service or activity will be fulfilled. It is the systematic measurement, comparison with a standard, monitoring of processes & an associated feedback loop that confers error prevention. This can be contrasted with quality control, which is focused on process output.
QA tends to be focused on measuring & examining quality and improving the software through process improvements, thereby guiding the release to customers. Although testing activities usually do take place in this organization, the main focus of QA is on the processes and procedures of how software development activities take place.
