Quality Assurance (QA) is the system used to verify that the entire analytical process is operating within acceptable limits, while Quality Control (QC) is the mechanisms established to measure non-conforming method performance.

The Levey-Jennings chart is a form of statistical process control (SPC) graph commonly employed in laboratory quality control contexts. Unlike the Shewhart individuals control chart, it relies on the long-term estimate of sigma instead of the short-term estimate within subgroups or samples. Control limits for proportion data are set at 10-20-30…[Read more]

Systems Analysis and Design is the formal process of studying a problem and creating a solution.

It involves collecting and interpreting facts to identify problems and planning a new system defining particular components to replace the existing system in order to satisfy specific requirements.

System Analysis and Design -…
