[SystemSafety] Comparing reliability predictions with reality

[Robert P Schaefer]

hi, Peter.

  sorry, for some reason this went to my spam folder.
 
  I have worked on my share of successful large projects and failed projects. 

  I cannot discern a difference that can be tied to one single thing. 

  And once you look at many different things, causality quickly gets lost.

  I’ve read, and believe in, Reason's swiss cheese model of faults, I wonder if there’s an equivalent swiss cheese model of success?
