From GSIM brochure:
What is the relationship between GSIM and GSBPM?
GSIM and GSBPM are complementary models for the production and management of statistical information. GSBPM models the statistical production process and identifies the activities undertaken by producers of official statistics that result in information outputs. These activities are broken down into sub-processes, such as “Impute” and “Calculate aggregates”. GSIM models information that flows between these sub- processes.
Greater value will be obtained from both models if they are applied together. Nevertheless, just as GSBPM has been applied to date without GSIM, it is possible (although not ideal) to apply GSIM without GSBPM, or an organization-specific model derived from GSBPM.
