OPTOSA combines a data processing module that builds and constantly updates operational knowledge related to sales positioning with a decision assistant that uses relevant aspects of the knowledge for helping the tasks of the different teams along the integrated chain of the sales. After reviewing the challenges of the approach, we discuss the first significant experiments with OPTOSA on some formalized use-cases.enText/Conference Paper1617-5468
