My colleague presented my analysis as “my dashboard.” Do I correct it now?

In a client meeting yesterday, my colleague said, “I built this dashboard to show where the delays are.” I was sitting beside him. I’d cleaned the data, worked out the measures and made the charts. He’d arranged the slides and handled the client’s questions.

We were both assigned to the project, so I wasn’t expecting a speech thanking me. But when the client asked who could explain an unusual result, they directed the question to him. He answered vaguely, then asked me to add something.

I stayed quiet about the ownership because interrupting would have made the moment strange. Afterward, he thanked me for “helping with the numbers.” I can’t tell whether he meant to take credit or whether that’s simply how he describes a piece of work he presents.

There’s another client review next week. My manager wasn’t in yesterday’s meeting and has mainly seen the slides. I’m worried that saying nothing will establish a version of the project where I assisted and he created it. I’m also worried that making a formal complaint over one phrase will damage a partnership that otherwise works.

Would you speak to him first, put your contribution in the next update, or raise it with the manager? What would you actually say?
