SuccessFactors has come a long way since I wrote this post originally and org visualisation is now on the 2016 product road map. Also, there are other vendors out there with light weight alternatives such as Huris, ready and available on HANA in the app store. That is great news and a good move.
It seems that Nakisa has finally come up with a solution for this topic and I thought I'd let everyone know about it. The product is called "Hanelly" and it uses real-time data from SuccessFactors Employee Central to visualise organisations. It also does more than that, of course, coming from Nakisa
The decision whether to use this or one of the more lightweight HANA based versions that are bound to be simpler and cheaper to implement relies on a more detailed analysis of course.
All the best,
Erik
