The Generic Statistical Business Process Model (GSBPM) is a means to describe statistics production in a general and process-oriented way. It is used both within and between statistical offices as a common basis for work with statistics production in different ways, such as quality, efficiency, standardisation, and process-orientation. It is used for all types of surveys, and "business" is not related to "business statistics" but refers to the statistical office, simply expressed. It comprises three levels: Level 0, the statistical business process; Level 1, the eight phases of the statistical business process; Level 2, the sub-processes within each phase.
