One of those strongly related with the competitive strateg y of the companies is to develop better quality products faster and cheaper than the competitors. The companies have been investing great amount of resources in computer applica tions that aid the new products process development, such as: Computer Aided Des ign (CAD), Product Data Management (PDM) and Enterprise Resource Planning-(ERP) , only to name a few. A quick investigation inside these companies reveals that the computer applicati ons are being used in an isolated manner yielding automation islands inside the companies as a result.

Based upon this criterion as well as the product complexity level of the , the companies can be usually classified into two categories: design center ed or manufacture centered. This activity classification of the companies is fundamental to establish the in tegration path between the PDM and ERP systems that differs greatly for both cat egories. This is due to the fact that the PDM systems are priority of the design -centered companies whereas ERP systems are priority of the manufacture centere d companies. The product structure (BOM Bills of Material) possesses a prominence position am ong the fundamental product information, because it represents the first step fo r the elaboration of a base of product data to be integrated. The BOM is also an element that generates integration once its data are used in the accomplishment of the activities of several areas of the company, as engineering, quality, PCP , purchases, maintenance, costing, marketing, sales and configuration, technical attendance and technology of information.
