The release of GRC 10.0 really simplifies the architecture for the suite of GRC applications. Now Access Control, Process Control, and Risk Management are all together in a single ABAP stack (system). Now crystal reports are possible without the need for installing the Business Object Enterprise Server anymore. This is a big advantage. Plus, the entire suite runs in the latest NWBC (Netweaver Business Client) interface. A Portal is optional.
I was happy to present again at this years GRC 2011 conference. I presented technical architecture and landscape for the GRC products.
I will respond to any blog post with questions about the technical aspects of the GRC suite. I have upgrade and migration experience to share also.
