In an integrated product and production development environment, where changes in tooling design affect the product design and vice versa, access to design rationale of tooling would support concurrent development of new product variants and required tooling. This paper presents an information model that enables easy capture and access to the design rationale of toolings, moreover, supports tracing relevant information within different design software applications. A solution based on integrating SolidWorks, Microsoft Excel, and Microsoft Word has been developed and an industrial case study, where the system is introduced and evaluated is presented.
