Better Information Systems (IS) could be developed, if experience were used. The use of experience could be applied in any phase of the Information System Development process. This paper presents a framework that applies the Case-Based Reasoning (CBR) method to enable the use of experience in conceptual modelling. This framework could be used in several conceptual modelling types, as long as graphical modelling languages were used. Our framework was implemented in an Internet application that has a modular structure.
