I am working as part of a 6 member team in an agile environment. We have our manager joining the stand-ups everyday. I also have this other guy in the team who is as experienced in the company as I am. The only difference being he is a full time employee and I am a consultant.
Now as part of daily tasks it has happened in the past that this guy gave some information (which as per the company policies only full timers usually know) and based on that we take our day to day decisions on technical tasks. But later on we came to know that what he said was incorrect and the path that we have taken is incorrect. But usually our manager doesn't pay attention as to where the information came from. He only cares about whether the job is done correctly or not.
So my question is without looking like I am blaming him, how can I make the manager aware that because of the information given by this guy, that we have taken this route? My objective here is only to fix my reputation in front of my manager.
Note: This question is not duplicate of this one. The OP is outright blaming others to be incompetent. That is not my issue. The other guys is in this environment for long time and he adds immense value to the team. It is just that some information came from him which was incorrect. I am not even criticised by the managers to be incompetent. I have a proven track record at this place.
Edit: We sit in a closed room together and generally this information comes verbally.
