The goal of documenting GPSs is to harmonize evaluation practice among ECG members and improve understanding of evaluation practices. Derived from the evaluation principles of the OECD‚ÄìDAC, these GPS were built on good evaluation practices and were designed to be consistent with the MDBs' operational policies.
The Big Book addresses overlaps noted in the individual GPSs, and resolves differences in terminologies, if any, without losing the original intent of the four GPS reports taken individually. It rearranges the individual GPSs, but there are no material changes or deviations from the original content.

Original Good Practice Standards
NOTE: The Big Book on Evaluation Good Practice Standards is a living document that will be revised from time to time to reflect changing conditions in development evaluation.
