|In a process with no variables, the output of a process would be in a Standard Atmospheric Condition.|
|Unless the variables of a process is accounted for, the process outcome is random.|
One quality of human factors is resilience, or the ability to bounce back from an unexpected variable. Humans have the ability to react both with a proactive solution, or with a reactive solution. Human factors also have the ability to apply unconventional process adjustments to return back to desired outcome. It is when variables are not accounted for that perfectly good inputs to a process could produce catastrophic result. The cycle of a process does not stop with the output or result. The cycle ends when human factors take control of quality assurance of the output. Safety in processes is only as good as the human control of the output.
