Quality Assurance

At John J. Steuby we define Quality Assurance as a way of preventing mistakes and defects in manufactured products and avoiding problems when delivering solutions or services to customers; which ISO 9001 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.

Quality Assurance comprises administrative and procedural activities implemented in a quality system so that requirements and goals for a product, service or activity will be fulfilled. It is the systematic measurement, comparison with a standard, monitoring of processes and an associated feedback loop that confers error prevention. This can be contrasted with quality control, which is focused on process output.

Quality assurance includes two principles: "Fit for Purpose" (the product should be suitable for the intended purpose); and "right first time" (mistakes should be eliminated). Our Quality Assurance system includes management of the quality of raw materials, assemblies, products and components, services related to production, and management, production and inspection processes.

The task of engineering is to make it work once, while the task of Quality Assurance is to make it work all the time.
