As someone that has managed users and systems, I can confidently tell you that these systems are overkill, and as a result they can do more damage than good. It in essence, is using a sledgehammer to nail in a small tack... what that means is you don't get the accuracy you need an you end missing the mark because of lower buy in.

More often than not, the people you need to have use it end up seeing the tool as the object of disdain. They put minimal info into it, so you get skewed results out of it. The feature sets that many of these CRM systems include in their programs are rarely used and are nothing but fancy baubles, completely useless to small to medium sized businesses. I think most companies will have a better user experience with something simpler...
