Résumé
The implementation of Enterprise Resource Planning systems (ERP) can not be undertaken by using the same techniques that for the development of software since ERP systems are already developed applications that are implemented in an organization by means of parameterization and customization. Because of that, the classical measurement methods are not fully applicable to the estimation of the cost and effort of this kind of projects. This article presents an estimation model of ERP implementations that takes into account the characteristics of the standard package (functional and parameterization transactions), data migration, customization, reporting, as well as the user training. This model integrates function points and other models and adjustment factors that are used when other methods are not applicable.
