We all know not to shoot the messenger. We don’t do a great job living up to it, but we know it in theory. Something people don’t seem to know even in theory is not to credit the messenger. By that I mean attributing success to the person who’s telling you about it. I see my twelve year old son do this, and I also see senior product directors do this. Sometimes it’s because someone is the point of contact for managing an incident. Sometimes it’s an ongoing effort, and you happen to interface with one person more than the rest of the team, often because they report to you.
Either way, since all information flows through them, it can be unclear who’s actually doing it.

What we can do in that situation is unconsciously think of that person as the one doing the work. We might even say that, either explicitly, like “Bill deployed a fix,” or implicitly, like “Sharon delivered the new workflow.” It’s usually a team effort. Of course, if you ask people, they’ll say they know that, but it’s not about what they know when you ask them. It’s about what they know when you’re not asking them. It’s about what other people hear.
