The ability to create custom dashboards that are easily accessible from any device is great! It's easy for non-technical users too as most functions can be navigated via drag & drop functionality.
I have yet to find anything i dislike about this software. There really isn't much room for criticism other than perhaps being able to view more data at once would make things easier (but not impossible). We're using Cogniom in conjunction with our BI platform which allows us to quickly build out reports when needed without having to go through an IT department approval process first - allowing faster turnaround times for clients who need them right away.
