I recently was on a call where we deployed one of IT projects to production with about 30 people (many from top management) and our technical support team. There was one person from the support team who likes to make remarks. After we proceed with the deployment, about in 30 minutes this person asked what we are doing right now. I explained our step. He said: "Please, always let us know what you are doing, we have to know". I told him on the call that we informed about this step before during the call (I explained it 10 min ago on the same call but somehow he didn't get it), while he repeated the same: "Please, always let us know what you are doing, we have to know".
The problem I have that this person from the tech support team sounds a little bit political as if I said that we already informed about our steps, he can just believe it if his real intention was to clarify. Somehow, he wanted to say this remark publicly and repeat it after my answer and I didn't like it and it sounds to me more political rather than cooperative.
My goal is to find out how I can handle a similar situation with him during the next time. I didn't want to talk too much on that call personally with him, as the management on the call might get a feeling that we are fighting. I had some ideas to answer the next time like this: "Perhaps, you were not around when I communicated our actions about this step. We are proceeding with the deployment. If there are still any questions, I can ask one of my developers to come to your room and explain it."
How would you handle it?
