SAP's reign is declining
Back in the 80s it was said that no manager would be fired for selecting IBM (mainframe or software). Along came a paradigm shift from the big iron mainframes to smaller, client-server based systems. SAP was(and is) the leader in these systems. However, they have lost sight of why companies switched from the "big iron" and in-house supported COBOL/CICS systems. It was because the client-server gave flexibility. However, over the years it has grown into exactly like the software it replaced. Big, bulky, slow to change, difficult to implement. Expensive to support (both hardware and software). No longer with SAP and similar systems be a "given".
A new paradigm shift will be accelerated by our current economic downturn. Innovative companies will return to the roots of having a core staff of in-house Business Process/Programmer combination people that can leverage the power of various FLOSS ERP systems and their supporting communities. The result is that systems such as Compiere, OpenBravo and other systems will move toward a large scale Enterprise support. Utilizing technology such as Evergreen does with XMPP these systems will be scalable from the smallest implementation on one PC server to supporting Enterprises all over the world.
Finally, organizations will be able to innovate their support systems at the same speed as they need to innovate their business. Waiting for months (if not longer) for "the next release" will be a thing of the past. AND that folks is what we need in the 21st century.
