MOP Writing & Change Management
Most data center outages involve human error, and most of those come from procedures that were missing, wrong or not followed. AAAT3 writes, reviews and runs methods of procedure (MOPs) and change management so risky work goes exactly to plan.

Common questions
What is a MOP?
A method of procedure is a step by step script for work on or near critical systems. It lists each action, who does it, what reading to expect and how to roll back if something goes wrong.
What is the difference between a MOP, SOP and EOP?
A MOP covers a specific planned change. An SOP covers routine operations. An EOP covers what to do in an emergency.
Can AAAT3 write our MOPs?
Yes. We walk down the equipment, write the MOP with checks and rollback steps, and review it with your team.
Do you review vendor MOPs?
Yes. We review vendor and contractor MOPs for technical and safety gaps before approval.
How long does a MOP take to write?
Simple MOPs can take a day or two. Complex shutdowns and cutovers take longer because they need walkdowns and reviews.
