Tableau is being used as user friendly ad-hoc reporting tool for end users who may or may not have a technical background. The vendor provided on demand training is very well done and someone who has never heard of Tableau can become a functional Tableau user in about a day. It is a nice, flexible tool to complement OBIEE 11g, the enterprise BI tool. It is available to any department within the bank and is being used by roughly 30 or so different groups within the bank. There are about 3,000 Tableau Server users currently, with substantial user growth projected by year end. Each of these groups have their own unique website on Tableau Server and site administrators control who can see what. This can be done on an individual basis, or on a group basis. Also, a member of site A can not access site B.
