Our company employs Q.C. officers on every step of production, and report to management who make the decision to allow or deny the release of the products. Quality Assurance officers are strategically placed to improve and stabilize production, and associated processes, to avoid, or at least minimize, issues that led to the defects in the first place.
Our QA is systematically monitoring and evaluate the various aspects of the products, to maximize the probability that minimum standards of quality are being attained by the production process. QA cannot absolutely guarantee the production of quality products.Quality is determined by the product users, clients or customers, not by society in general. It is not the same as ‘expensive’ or ‘high quality’. Low priced products can be considered as having high quality if the product users determine them as such.
Steps of Quality Assurance Process
We have customized this process to better assure our clients and end-users that their products meets every standard known and internationally accept
Failure TestingFor us, failure testing or stress testing is a valuable process that needs us to perform on each product. In mechanical terms this is the operation of a product until it fails, often under stresses such as increasing vibration, temperature, and humidity. This exposes many unanticipated weaknesses in a product, and the data are used to drive engineering and manufacturing process improvements. Often quite simple changes can dramatically improve product service.
Statistical ControlOur company use statistical process control to bring the organization to Six Sigma levels of quality, in other words, so that the likelihood of an unexpected failure is confined to six standard deviations on the normal distribution. This probability is less than four one-millionths. Items controlled often include clerical tasks such as order-entry as well as conventional manufacturing tasks.
Traditional statistical process controls in manufacturing operations usually proceed by randomly sampling and testing a fraction of the output. Variances in critical tolerances are continuously tracked and where necessary corrected before bad parts are produced.
