On top of that, wait until the entire system is supposed to "go live" instantly at every hospital, pharmacy, doctor's office, clinic, and government agency. And everybody logs on at once (like a Monday morning),and starts updating stuff. And expects the changes to be available instantly to the millions of people using the system. Massive crashes from traffic tsunamis that will happen from time-to-time. (Like "daily").
The system has to be built to handle peak stresses at least 100x greater than daily activity. Assuming it ever works with more than 4 or 5 real users logged on at any one time in the first place. Anything less than sub-second response time will lead to revolt. And I'm sure they have the safety and redundancy of the world's largest system outside of the NSA all figured out already.
This is the easy part, the slow manual entry of original data, with plenty of time (measured in months, rather than milliseconds) to get things right.
Decent metrics.
Makes you wonder if the number of reported visitors weren’t really a number of hits on one processor’s IP port.
