QA Testing Interview Questions and Answers

QA Testing Interview Questions and Answers

QA is a way of preventing mistakes or defects in manufactured products and 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 and rejection in quality control, and has been referred to as a shift left as it focuses on quality earlier in the process.

ISO 9000 is an international standard that many companies use to ensure that their quality assurance system is in place and effective. Conformance to ISO 9000 is said to guarantee that a company delivers quality products and services. To follow ISO 9000, a company’s management team decides quality assurance policies and objectives. Next, the company or an external consultant formally writes down the company’s policies and requirements and how the staff can implement the quality assurance system. Once this guideline is in place and the quality assurance procedures are implemented, an outside assessor examines the company’s quality assurance system to make sure it complies with ISO 9000. A detailed report describes the parts of the standard the company missed, and the company agrees to correct any problems within a specific time. Once the problems are corrected, the company is certified as in conformance with the standard.
