1. The life of a Naval ship is now supposed to be 45 years, τ_(HULL) = 45 2. Everything on it has a smaller life cycle, τ_(CS) < 45, τ_(HME) < 45, τ_(C5I) 45 3. The threats develop in shorter time frames, τ_(THREAT>< 45 4. My hypothesis is that this scenario will get worse, especially τ_(THREAT) 5. In response to potential or real threats, as well as capabilities, we change missions a. BMD, IAMD, Cyber, Autonomy, and others not yet envisioned... 6. If we can't resolve this, we lose, either through irrelevance or cost 7. So, how do we resolve this? How do we maintain Value Robustness through the service life? 8. Desired properties of systems that manifest after the system is in use. a. Not the primary functional requirement b. Typically concern wider system impacts that manifest and may not necessarily be designed-in explicitly a) Execution qualities that are observable during operations b) Evolution qualities that are underlying in the architecture c. Intangible d. Often, but not always, end in "ility" e. There's about 60 of them listed on Wikipedia a) And yet I can go list some off the top of my head not there A. Affordabilllty, survivability, vulnerability, capability...
