You suspect you have started to get a bad reputation with your boss.

If you want to thrive in a Lean company, your boss must see you as being supportive of continuous improvement efforts. If she doesn’t see you that way, it is because of one of two reasons. Either you really aren’t supportive of Lean, and the assessment is accurate, or you are supportive of the improvement efforts, and your boss is off the mark about how you feel.

Regardless of the reason, it is up to you to change her mind if you want to do well in the future.
