We've selected "Business Analysis Tool" due to several reasons:
1) the application has a flexible distributed architecture, and this allows to minimize the demands to hardware of the client workstations (in comparison with the "greedy" Excel) and to get better time of report generation.
2) due to compressed HTTP traffic the client can get comfortable access to the analytic data from any remote PC with internet access;
3) support for Analysis Services 2000 and 2005;
4) comfortable and rich interface of building reports, tools for logging and monitoring, centralized administration.
5) loyal license price in comparison with rivals;
6) the development team: fast response, sensitivity, flexibility and professionalism.
