SYSTEMS IN GENERAL WORK ONLY AS WELL           AS THEY NEED TO.
A crappy system with strong self-preservation       instincts beats a great system.
THE SYSTEM ALWAYS KICKS BACK
Systems usually treat change as a threat and            reject or resist it.
PEOPLE IN SYSTEMS DO NOT DO WHAT THE    SYSTEM SAYS THEY ARE DOING
Once the system is known, bugs in the systemcan be exploited, typically by the people working                      there.

Total system collapse usually happens as a result      of a bunch of interrelated components.
COMPLEX SYSTEMS ACT UNEXPECTEDLY
Even when in normal operation, its not by the   same logic that an outsider would use.
A COMPLEX SYSTEM THAT WORKS USUALLY  EVOLVES FROM A SIMPLE SYSTEM THAT              WORKS.
Craigslist is a great example of this.
NEW SYSTEMS GENERATE NEW PROBLEMS
Systems arent bound to act in the best interests               of their creators.
