I am dealing with a colleague who is trying to sell a product we don't have.
He pitched an idea for a new product internally, but nothing is committed or confirmed, and there is no ETA or any development being done.
My colleague is trying to sell customers his project so that he can "create an emergency" by going back to management and saying "I mentioned my new product to customers and they wanted buy it, you need to get started on it now". If every team did this, we would be in absolute chaos, and our reputation as a company would be shattered.
I tried to explain to my colleague that, as a company, we don't sell things we don't have, and we don't mention "upcoming products" when nothing is committed for them. He replied "we are talking about the same thing, I don't see the problem".
I don't know how to deal with a situation like this, when this person is effectively saying and doing whatever he/she wants. This colleague is lying to my face to pursue his personal agenda. I am afraid that:
- if I explain there is a process, he will accuse me of thinking about the process, not customers;
- if I explain nothing is committed, he will repeat that "everything was already decided" (that's not the case)
- if I ask him to explain what support he has for what he is telling to customers, I might sound too aggressive or inquisitive and this will be used against me, e.g. "this guy complained because customers wanted to buy my project"
Question: how do I manage colleagues who lie and exaggerate to pursue their own agenda?
