You have good customer/prospect audience segmentation data.
But it's spread all over your enterprise information systems, in restricted databases - customer records in one location, prospect information over there, sales transaction history in a different location, and customer spending trends in yet another database. Not to mention the additional, separate information systems for your individual business units – none of which "talk" to each other. If you can find the data, can you compile, analyze and sift through the mountains of information to define and develop exactly the audience slices you need?
And even though you have followed current best practices and purchased prospect data sorted into "clusters," is it really delineated enough to make communicating with prospects more productive and efficient? Does your data need supplementation with knowledge from outside databases to maximize its relevance? Does it need dynamic database segmentation to release its true value?
