I've been studying CPM OneBox for about 6 months. What initially seemed to be a minus, namely that everything needs to be customized and there are practically no ready-made box solutions, is now ready to be attributed to the pluses. The system is not the most simple and intuitive, but after studying it, you can set up a lot of things exactly as you need to meet your company's requirements. Staff, support goes to the meeting, helps in adapting to the system. But you need to be prepared for the fact that you need to determine the exact requirements from the system yourself, until you understand what you need from it. You will not build the architecture you need.
It seems to me that for Vanbox it would be useful to have some typical or most successful boxed solutions for newcomers in the implementation of CPM in their company. So it's easier to start using and studying the system, and further it would be easier to set up the necessary requirements already for individual configuration.
