I’ve used a number of different solutions, both as a customer, and as an implementer. I’ve seen many sites where a complicated enterprise system locks the customer into the solution which doesn’t meet their needs (for whatever reason; sometimes complexity, other times aging functionality that would take too much effort to update). Yellowfin doesn’t try to do everything – it is a BI presentation and communication tool, and it does it brilliantly. Most customers switch to Yellowfin because they can’t get what they want out of their monolithic legacy systems. It can reside alongside more complex enterprise systems.
