Pros
They are very good at painting the vision and strategy for the company- if the compensation and rewards were in line, it would be highly motivating. It's difficult to find pros when the compensation is so out of line.
Cons
Was part of the Ariba acquisition in 2012, and now in early 2014 have been going through the compensation planning for the year. The company speaks about their philosophy of being open and fair about compensation, but they tried to hide all of their bands and pay grades from Ariba employees. They didn't do this very well, and it's now pretty widely known that the Ariba employees are paid well below the SAP salary bands, but SAP has no plans to rectify this. So, being a former Ariba employee means that you make a fraction of what your SAP counterparts make for the same level of work and responsibilities.
