In this work, we are proposing a new model for knowledge discovery in database (KDD) named "SCRUM-BI". It based on SCRUM agile methodology to enhance the way of building Business Intelligence and Data Mining applications. This model characterized as more adaptive to the changing requirements, priorities and rapidly evolving business environments. SCRUM-BI Also improves and enhances the process of knowledge obtaining and sharing, which contributes to support strategic decision-making. The model was validated using a case study on the telecommunications sector in Syria.
