Acronym for Product, Process, Resources. 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.
