The Georgia Tech Process to Product Modeling (GTPPM) is a formal process-centric product modeling method. It enables capture of domain-specific information and work processes through process modeling. The method was initially developed in response to the need to integrate multiple use-cases with differing data definitions from different companies. It automates and applies formal methods to aspects of process and product modeling that have traditionally been negotiated by committees. It has been deployed in several research projects, in addition, as an information flow analysis method rather than as a product modeling method. This paper reports a case of deploying GTPPM as a product modeling method, using a purpose-built software tool for its implementation. The case study in the domain of precast concrete construction demonstrates that it is possible to semi-automatically derive a product data model from the collected information through normalization, information integration, and conflict resolution processes.
