Designers need to reuse relevant knowledge types to make important decisions. These decisions are based not only on experience, but also on key knowledge global partners. A methodology to support information-knowledge management for global collaboration using DFX, PDM and Expert System tools is proposed. This new approach shows a manner to provide information from each stage of the product lifecycle to the designers through a PDM system. In addition, it includes a manner to store and share the knowledge created during the DFX process using an Expert System. This methodology provides integration to product realization technologies while supporting design stage in a collaborative environment when a large amount of information and knowledge to get a decision is required. The new approach implemented provides important benefits such as launching time and cost reduction, increased efficiency of designers and product innovation.
