What is the difference between screening quality data and decision quality data, and how are each used in the Triad approach?
Within the context of the Triad s second-generation data quality model, “data quality” is assessed according to the data s ability to support confident decision-making. “Decision quality data” are defined within the Triad as data that can support the decision to be made at the desired level of confidence. Decision quality data sets often are comprised of data from different sources (e.g., a smaller number of analyses from standard fixed laboratory methods supplemented with a larger number of real-time measurements) so that all aspects of data uncertainty (sampling, analytical, and relational) are managed. The term “collaborative data” is used in the context of the Triad to express this. Following the same line of reasoning, “screening quality data” are data that provide some useful information for the decision to be made, but taken alone are not sufficient to make the decision at the desired level of confidence. Screening quality data are data of known quality, however, there is either
