Analytics and BI today must reach all users across an organisation, from those needing simple KPI measurement visualisation to analysts testing outliers to see if they are the new reality,-  a full continuum of usage across the enterprise. Many users work at a desk and on the move so no analytics solution can be anything less than "mobile-ready"

Ready for users to access on any type of device at any time, anywhere. 

This report from Ventana Research shows that some of the most popular BI & Analytics solutions fail miserably on these criteria and I urge any buyer to consider this report, not to mention those by Butler, Gartner, Forrrester et al before being seduced by sales presentations majoring on eye-watering visualisations.

Just ask them to demonstrate responsive design in action and then test in real-life with your own data before parting with hard-earned money!
