- Data for reliability analysis
- Field data collection system
- 4.2 Guidance for obtaining quality dataTo obtain high quality data, the following measures shall be emphasized before the data collection process starts:. investigate the data sources to make sure the required inventory data can be found and the operational dataare complete;. define the objective for collecting the data in order to collect relevant data for the intended use. Examples ofanalyses where such data may be used are: Quantitative Risk Analysis (QRA); Reliability, Availability andMaintainability Analysis (RAM); Reliability-Centred Maintenance (RCM); Life Cycle Cost (LCC);. investigate the source(s) of the data to ensure that relevant data of sufficient quality is available;. identify the installation date, population and operating period(s) for the equipment from which data may becollected;. a pilot exercise of the data collection methods and tools (manual, electronic) is recommended to verify thefeasibility of the planned data collection procedures;. prepare a plan for the data collection process, e.g. schedules, milestones, sequence and number of equipmentunits, time periods to be covered, etc.;. train, motivate and organize the data collection personnel;. plan for quality assurance of the data collection process. This shall as a minimum include procedures for qualitycontrol of data and recording and correcting deviations. An example of a checklist is included in Annex C.During and after the data collection exercise, analyse the data to check consistency, reasonable distributions,proper codes and correct interpretations. The quality control process shall be documented. When merging individualdata bases it is imperative that each data record has a unique identification.
