If there is one thing I wish I could teach regular people it is to view an organization, a community, a city, a country, the world, as a complex adaptive system, where you have, always, effects and reactions, often unintended and unforeseen.
Just like a distributed computer system.

When you make changes in a complex system you will consciously and subconsciously make assumptions about what is already there. What you can rely on.
A lot of you saw that with the Outlook outage. How many of your processes broke when mail and calendars were unavailable?
That when you make a change in that system, other parts will react and adapt to your changes.
You need to consider, as much as you can, what those second order effects are, maybe doing the change on a smaller scale to observe the ripple effects.
At minimum monitor the system after.
