Special Interest Group, formed 1995

This SIG is where CEOs and marketing directors from the most important software suppliers and providers of services in the area of PLM meet three times a year to exchange experiences and discuss the general development of the market. Unfortunately, the location chosen is not always as beautiful as that of  Kloster Irsee (Photograph: Christoph A. Hellhake). But we do our best. Highly capable presenters go into detail on subjects that are of immediate concern to the industry and manufacturing industry representatives report on practical application.

The IT offerings of the member companies concentrate on the product creation process in the manufacturing industry and on the management of product data encompassing the entire product life cycle that is created there. From CAD/CAM/CAE and PDM through to the cooperation of distributed teams, project management and virtual reality and onto interfaces to other areas of application such as ERP, SCM and CRM.

Between the meetings, the sendler\circle also acts as a hub for communication between the participants and is the industry interface to third parties.
