System Safety

Safe Systems are simple Systems

The inflation of features in user interfaces is opposed to this simple truth, so it is essential, to analyze gather and isolate safety critical components.

Save Systems have no unsafe States

Whenever possible, unsafe states should be avoided by design. Like it is safer, to limit the pressure in a ventilator, by using a bellow charged with a limited weight, instead of controlling the pressure, it is easier to have a limited set of states and a well defined number of transitions, than to keep the system state in a set  of parameters and maintain consistence programmatically.
