|
standard operating procedure (SOP) specifications |
must spell out all information and instructions assuring variations in production will be held to within acceptable established ranges |
|
quality |
refers to the combination of all attributes of characteristics of a product which, when compared to a standard, serves as a basis for measuring the uniformity of the product and determines the degree of acceptability |
|
quality |
combination of all attributes of characteristics of a product |
|
quality control |
focuses more in the product |
|
quality assurance |
focuses more on quality in processing the product |
|
quality assurance |
responsible for determining that systems, facilities and written procedures are adequate and are followed to assure that the product is controls and will meet all the applicable specifications. |
|
indeterminate error |
also known as random error, it caused by uncontrollable variables which cannot be detected/eliminated and they manifest by slight variations in a series of observations. Affects the precision of measurements. |
|
determinate error |
also known as systematic error, affect the accuracy of results. It has definite value or cause and leads to bias in measurement techniques. This error can be predicted and prevented. |
|
corrections |
proper training and experience, calibration or proper instrumentation maintenance and proper method development by the QA |
