EM has never added efficiency to any company that it has purchased.
Get ready to explain every little piece of logic to your new EM Boss. Verbally explaining will not be sufficient, a PowerPoint One-Pager is required every time.
Your typical 5 minute discussions with a decision will become 5 days of creating a PowerPoint for your new EM Boss to present to his EM Boss-then those two id--ts that do not understand the topic will make a poor decision without you in the room.
If that decision proven to be wrong, you will be blamed for your inadequate PowerPoint slide.
You will get the NSI and the two EM bosses will move upward without learning anything.
