Yes, many times.. Also, I have approx 5 different managers (different story, but at least this is fun). They listen, and nothing happens. Looks like until everything works, all complains are ignored. To some extent, it makes sense.

Looks like only failure makes a difference. An "Italian strike" - just follow the rules they insist on, and when some important business updates miss the hard deadline there is a s&@tstorm from business + they start to fix the system.

May be another good thing is that I train my EQ a lot and easily read between the lines even in the emails

Please share your experience, how difficult it was (in the worst case) to make a significant change to PROD?
