We are a small company of about 100 people. I along with another senior member (same designation as me but older and more experienced) are jointly incharge of developing a product.
We have a team under us but our manager has made it clear that we can decide amongst ourselves who will do what and he does not intend to get into details as long as the product is delivered.
We are having reasonable success with it but my problem is this other person has not made any meaningful contribution to the project. He is always available in meetings but does not help with any useful contribution during or after. I am doing all the planning and execution.
He is not blocking my work or being counter-productive. He is in fact reasonably friendly as well. He does have other projects as well and he is probably doing well there. Just no contribution to my product.
Initially I was not worried about the credit but now I am not very happy with the idea of him sharing the credit for not doing anything. It is even more frustrating when he says "WE have built this".
So my question is how to handle the situation above? Not take any action or let someone know and if so how?
Edit: It is not duplicate of the question marked above because it is not that this person has jumped at the end to take credit. He was there all along in all meetings and discussions. Just did not contribute. Also that question itself is closed because it is not constructive
