This work presents the case for the affordability of systems. These cases include transportation, such as commercial aircraft and railway systems. space shuttle, power generation systems. Case studies are presented for each of these categories showing cost to system modification ranging from no cost to moderate cost. Case studies include system type, scenario, adversity, resilience technique, outcome, and estimated cost impact. The conclusion is that these systems and the associated scenarios and techniques demonstrate that system resilience can be achieved with little or no cost impact.
