Abstract: A method and system for norming and/or standardizing product features, wherein the product features are defined by characteristic elements. A pool (e.g. a data base or a product catalog) comprising product features and characteristic elements is accessed bin a defined and controlled way to ensure that all data entries are based on a norm or a standard. This improves the interchangeability of in particular technical data within a company and also enables the exchangeability of in particular technical data between companies (CRM). Another aspect of the invention is a method and a system for searching a product, wherein the product features are defined by standardized elements or components.
