Preface: Why preparedness precedes readiness
A resilience system can be technically complete and still not deliver mission capability on the day it matters.
That gap between engineering completion and operational readiness is where preparedness lives. A cyber authorization pathway advances separately from the construction schedule, and they converge later than expected. A utility interface condition becomes clear during commissioning that was not available during site assessment. A water system modification involves coordination timelines the original scope did not anticipate. These are not anomalies. They are realities inherent to complex mission infrastructure, and they reinforce why preparedness must be a deliberate discipline from the start.
Preparedness and readiness are related but distinct. Readiness is the condition of being operationally capable: systems that support the warfighter’s mission today. Preparedness is the upstream work that makes readiness achievable: identifying dependencies, resolving unknowns, and integrating energy, water and cybersecurity across the project lifecycle.
Resilience investments deliver their greatest value when preparedness bridges the gap between engineering intent and operational readiness.
This playbook is about practicing that discipline.
