Bringing the service down and reducing performance. You should have left the service alone after you acquired it. It was working perfectly.
Leave staff alone to do what they're good at instead of diving headfirst into something they know little about thinking they can "improve" it.
They don't actually listen to your recommendations. They'll have meetings to discuss issues but just do whatever they feel like despite valid concerns raised.
Micromanaging needs to stop. If you want to keep quality employees, executive level staff need to relinquish control, even though that might be difficult for them to do. They should guide if necessary, but actually listen to those at the ground level who have more valid input than they realize.
