Abstract:Quality of data has many faces. Primarily, it has to be relevant to its users. Relevance is an outcome that is achieved through a series of steps starting with a planning process that link user needs to data requirements. It continues through acquisition of data that is accurate in measuring what it was designed to measure and produced in a timely manner. Finally, the data must be made accessible and easy to interpret for the users. In a more global sense. data systems also need to be complete and comparable. The creation of data that addresses all of the facets of quality is a unified effort of all of the development phases from the initial data system objectives, through system design, collection, processing, and dissemination to the users. These sequential phases are like links in a chain. The sufficiency of each phase must be maintained to achieve relevance. This document is intended to help management, and data system sponsors achieve relevance through that sequential process.
