Because Oracle products are development frameworks, your final results is as good as the people who implemented them. Make sure that your implementation team is the best it can be, at least for the first implementation. If something is implemented incorrectly at the start, it'll cost you a lot more to fix than to build a new system from scratch. Sometimes it can be so badly designed that it is impossible to fix. I've been working on implementation for 20 years and I have seen bad implementations everywhere. In fact, I have seen the same tools implemented in the same team by two different people, with one being a success and the other a failure. In the same company, one department says that the tool does not work for them and another says that the tool is the best. The only difference was the implementer. Make sure you get a good team to implement it. The tool has its flaws, but most of time (99%) it is the implementer's fault that you have a bad or slow model.
