When properly analyzed and leveraged, big data enhances customer engagement through targeted, personalized and contextual marketing. The data also provides significant business intelligence that can help organizations achieve a variety of goals, including understanding their public image, increasing production efficiency or enhancing customer service. The primary problem with big data has always been the difficulty in correlating the information collected to obtain actionable insights. There is simply too much data for human analysts to find worthwhile information without the proper tools. Microsoft contends that humans need not be replaced in the process of extracting meaningful intelligence from big data, but they should be empowered to maximize the benefits that the data can provide. Adding support for Cortana and artificial intelligence to Dynamics 365 CRM is one way that Microsoft is attempting to give humans better tools for finding and using insights hidden in big data.
