This report, by noting the variation in EPC methodologies, proposes a set of criteria that could be used to categorise those differences such that EPC frameworks can be better understood and compared. The criteria are designed with both current and next-generation use of EPCs in mind. They are then applied to a selection of current and next-generation EPCs to illustrate how a multi-criteria framework for reviewing EPC methodologies may aid our understanding of how to use those EPCs, and where they are less suitable. The final results show multiple occasions where EPC methodologies have to find a balance between different ambitions, such as that between detail and replicability of methodology. Where EPC frameworks take different choices on this balance, this should inform our choice of when and where to apply this framework.
