Roadrunner mode probably sounds a lot like the "crisis mode" we're all used to in most orgs, but it's actually more like supercompensation principle in all types of learning and training. You focus w/ everything you have, and then recover. Most orgs try to balance capacity, which results in this steady state of draining yet not really productive work. Theory of Constraints (which is what this thread is based on) says you should instead balance flow.
