                        successful resolution of the business problem.  he business sponsors needing the analytic solution play
                        the critical role in this stage by defining the problem, pro ect ob ectives and solution requirements from a
                        business perspective.
                 tep      rior to undertaking the data collection and data preparation stages of the methodology, it's vital to define
                        the data requirements for decision tree classification.  his includes identifying the necessary data content,
                        formats and sources for initial data collection.
