Sometimes we’ll draw a graph of something that isn’t moving yet, just in case it decides to make a run for it…Tracking everything is key to moving fast, but the only way to do it is to make tracking anything

Incorporate these paths into automated tests 1. Static Analysis – inspect program code for all possible run-time behaviors and seek out coding flaws, back doors, and potentially malicious code2. Dynamic Analysis
