I once told a manager he had a problem, and he told me he disagreed.
What? How couldn’t he agree with me? After all, he hired me to help improve things.
The only person with a problem in the above conversation was me. I could complain about how he’s ignoring an obvious problem. But until the manager sees the problem, he won’t be able to change anything.
Rather than telling others they have a problem, help them to see it for themselves.
Work with them to confirm the outcomes they want. Then, help them become aware of what they can’t see.
You can’t help someone change if they don’t think they have a problem. Once they do see it, there may be nothing more for you to do except watch them change.
You got this.
