Abstract: PDM system should best support the enterprise vision， so its selection should be guided by a scientific approach. Based on the analysis of the features of PDM project, a structured approach was promoted. Started from enterprise vision， the enterprise requirements were mapped into business objectives， operation objectives， process requirements， and a set of function requirements lastly. After quantified by Analytical Hierarchy Process(AHP)， the function requirements can be served as the most important aspects of the PDM system evaluation infrastructure. This approach has been applied to a manufacturing enterprise's PDM system selection process.
