Do you use professional business intelligence tools in your company?

Since last4 years, I have been using the IBM Cognos BI.
Works great when it comes to integrating data from multiple platforms.
Its got one of the best interfaces both for the developer as well as the end user, and the Transformer Cubes are one of the most widely used OLAP data sources in the IBM Cognos environment.
Also has security features and role based filtrations and permission administration.

To some extent since we do not have the ERP software to facilitate the dashboard reports.
