Engineering Economics
Price the exit for the day you can least afford it
The reason to leave arrives on a schedule you don't set, and takes whatever you are shortest of when it comes. A commitment you can't exit from weakness is permanent.

Infrastructure
An outage doesn't change the price of redundancy
The price of redundancy is the same the day after an outage as the week before. What the failure moves is the burden of proof, and it moves back.
Infrastructure
Your safe migration window closes before the deadline
Migration safety spends time: rehearsal, phased rollout, observation, rollback. Once the schedule can't afford them, the safe migration window has closed.
Risk Management
The irreversible decisions go first
Most risks are prices you can pay. The one with no affordable way back is different. Settle those decisions first, while you still have a choice.
Infrastructure
Procedural risk shrinks; structural risk doesn't
Some risks shrink with effort. Others absorb the same investment and don't move. One question tells them apart during evaluation.
Risk Management
Why novelty, scale, and time compression fail together
One factor is mundane. Two are manageable. Three is where failure becomes systemic, because each removes the safety margin the other two need.
