PPR is the acronym for Product, Process, Resources.
PPR is Dassault Systèmes' integrated model that interlinks representations of the Product, the manufacturing Resources (tooling, factory, operators) and the production Process.
PPR is a fundamental building block of Dassault Systèmes' PLM strategy and is found in CATIA, DELMIA, and ENOVIA. This integration means that when a user makes a product design change in CATIA, the change is reflected in the associated manufacturing processes definition in DELMIA and the resources data stored in ENOVIA.
