Quality Assurance in Practice
QA in medical industry:
QA is very essential in the medical field because it helps to recognize the standards of medical equipments and services. Hospitals and laboratories make use of outside agencies in order to ensure standards for equipment such as X-ray machines, Diagnostic Radiology and AERB.
QA in software development:
Software Quality Assurance consists of a means of monitoring the software engineering processes and methods used to ensure quality. The methods by which this is accomplished are many and varied, and may include ensuring conformance to one or more standards, such as ISO 9000 or a model such as CMMI.
Using contractors and/or consultants:
Consultants and contractors are sometimes employed when introducing new quality practices and methods, particularly where the relevant skills and expertise are not available within the organization or when allocating the available internal resources are not available. Consultants and contractors will often employ Quality Management Systems (QMS), auditing and procedural documentation writing CMMI, Six Sigma, Measurement Systems Analysis (MSA), Quality Function Deployment (QFD), Failure Mode and Effects Analysis (FMEA), and Advance Product Quality Planning (APQP).
