NASHUA, NH--(Marketwired - Oct 7, 2013) - Dresner Advisory Services today announced the publication of a series of 2013 Wisdom of Crowds® Business Intelligence Vendor Special Reports. The six reports, covering Actuate, Dimensional Insight, Information Builders, Pentaho, QlikTech, and Yellowfin, were created based on data collected from the Wisdom of Crowds® Business Intelligence Market Studies.

The reports provide a comprehensive analysis of each vendor's year-over-year performance on the Dresner 33-measure rating system which considers user input on the sales/acquisition process, product and technology, value for price paid, technical support, consulting services, integrity, and whether the vendor is recommended.

"Each year we create a limited number of special reports which examine the performance of selected BI software vendors," said Howard Dresner, founder and chief research officer at Dresner Advisory Services. "The Special Reports offer a unique look into the vendor's current and historic performance, highlighting the evolution of their product and services and demonstrating their response to user needs and requirements."

"Special Reports are a great complement to the flagship Wisdom of Crowds BI Market Study and provide an invaluable tool for organizations evaluating any of these BI vendors and selecting a BI solution," concluded Dresner.
