Statistics for managers individual work wk12 - Coursework Example From the foregoing, QC can be referred to as the technical undertakings used to ascertain that the gathered data are sufficient for the purposes of quality assessment. This comprises feedback mechanisms to ensure undertakings are operating as intended and planned, and to confirm that processes being done satisfactorily (Evans, and Olson, 2010). For instance, to ensure reliability and effectiveness of RTWQ (Real-Time Water Quality) Monitoring Program, QC procedures must be executed. The QC program components may include: maintenance and inspection of installation of RTWQ station, regular calibration and maintenance of the probe alongside its sensors, and collection of grab sample of water quality at the reinstallation period of the probe to be taken to the laboratory for assessment, among others. In theory, quality control for analytic performance comprises two complementary events: external QC and internal QC. The external QC entails reference aid from several other laboratories and involvement in international and/or national inter-laboratory data and sample exchange programs (skill testing; third line control) (Evans, and Olson, 2010). On the other hand, the internal QC entails the in-house processes for continual monitoring of tasks and systematic daily checking of the generated data whether such are adequately reliable to be out. The processes mainly monitor the partiality of data with the aid of control samples as well as the precision using duplicate analyses of the control samples and/or the test samples (Evans, and Olson, 2010). These events happen at batch level (second line control). Data modeling refers to the process utilized to described and assesses data necessities required to back the business operations within the extent of corresponding systems of information in corporations. The data modeling process, therefore, entails expert data modelers operating closely with corporate shareholders, alongside prospective
