In the course of making plans, Murphyjitsu is the practice of strengthening plans by repeatedly envisioning and defending against failure modes until you would be shocked to see it fail. Here’s the basic setup of Murphyjitsu:

1. Make a plan.

2. Imagine that you’ve passed the deadline and find out that the plan failed.

3. If you’re shocked in this scenario, you’re done.

4. Otherwise, simulate the most likely failure mode, defend against it, and repeat.
