Thanks both for your comments ... there is two parts to this . . .
1. Whether we can accurately identify a customer. let's say we can, and it is a binary field that says Active Customer True.
2. This is less a philosophical question and more a technical one. My question pertains explicitely and solely to modeler and RCA not so much MLM. Meaning from a reporting point of view in RCA there are ramifications for pulling out all the leads, or not pulling out all the leads. What have you guys seen done and why?
Also, in the case of maintaining multiple models how do you even prevent folks from entering an acquisition model from anonymous. I don't think this is even possible, it would require a batch campaign to pull them out of the system generated transition from stage 1.
I hope that clears up my question a bit. Keep the suggestions coming!
