Engineers for a financial system are planning how the system will work under high load. Since the system can handle 20,000 transactions per second, the engineers determine that it must process at least 15,000 transactions per second during periods of high load. According to “System Resilience Part 3” This step represents:

Ridgeline Grid’s development team adds strict input validation to its operator console to block injection attacks against the substation command queue. In the sprint review, the team lead reports this work under the heading “resilience improvements.” A reviewer pushes back on the categorization — not on the work itself, which everyone agrees was worth doing. What’s the basis for that objection?

Ridgeline Grid’s architecture review hits a disagreement. One engineer says “maximum number of simultaneous sensor connections the platform can handle” belongs under the platform’s Capacity requirements. Another says it belongs under Efficiency, since it’s about resource usage. A third says they’re both wrong to argue, because it’s legitimately both. Who has the right read?

Ridgeline Grid’s substations sit in a region with a history of copper-theft break-ins. Two separate investments are proposed. Investment A hardens the equipment enclosures so they resist forced entry and cutting tools even once an intruder reaches them. Investment B adds fence-line sensors that detect an intruder approaching before they reach the enclosure at all, triggering an automatic lockdown. How should these two investments be classified under Survivability’s two named tolerances?
