Planning Analytics (PA) has been available for over a year, first on the cloud as "Software as a Service" (SaaS) and, since December 2016, as traditional "On Premises" software.  We at InfoCat have been following the development of PA since we saw early, pre-beta, versions at IBM's Vision conference in May 2015 and are very excited by its capabilities. 

There is a good article published today on thought leadership site The IT Insider - "Budgeting in the Cloud".  They have really hit the key points, very succinctly, on why organisations are making such a meal of the planning process.
