3. Evaluation Factors and Analytical Process The scope of an ERP implementation project should vary in each case, but when analyzing processes, all possible interactions between these processes must be contemplated. Another important consideration is whether the main area processes have been included in the scope. If they have been excluded from the implementation scope, the information we get from the data will not be as valid as we need. All requirements should be structured taking into account two idecas: those processes within the scope that must be integrated in the ERP, and those that consider ERP as exteral software. These needs must be contemplated especially if some areas are not to be integrated. This could be the case if in the project, some processes have to work with an older application. In this case, we must be sure that, for example, the scope of implementation takes into account that such processes will be working in and old platform or application to ensure that integration will be possible and data integrity will be guaranteed. In the first group, we will find that many processes fit in the standard ERP solution, but others will need to be adapted to the ERP, or the ERP reprogrammed to fit company processes. Those are customized processes and the manner in which they are to be adapted is a major evaluation factor.
