Dashboards and resources

Hi everyone:

We're working on installing dashboards for our Managing Director, Development, Marketing, Artistic and Finance departments.  I'm wondering what your experience has been with any drain on local resources, requiring a larger local server, etc. 

We're in a consortium but we do experience local sluggishness due to bandwidth issues and in I believe not enough local resources. Before moving forward with all the installations, I'd love feedback on how this went for you and if you needed to do anything to avoid a drain on local resources.

Finally, does anyone have or know if a dashboard request document exists?  What I'm looking for is something I can send to each department to fill out letting me know how they want their dashboard configured and what information is important to them.

Thank you all!

Michelle
