[SystemSafety] Does "reliable" mean "safe" and or "secure" or neither?

[Tim Schürmann]

Hi Bertrand,
if i get you right, you're saying: One needs to access/address the
previous experience/knowledge of a person (with respect to culture/work
etc.) to make sure the underlying mental model of understanding/meaning
is similar/the same?

Regards
Tim

It happens that in French, the meaning of "intégrité" encompasses the same scope that the meaning of integrity in English, but that among the different meanings the "moral" one appears after the "untouched/intact" meaning.

Decades of sitting in engineering reviews has taught me that such emotional and ambiguous utterances such as this waste people's time, a precious commodity when you're building systems with other people's money.

It also focuses on the work not the person. "utter nonsense" implies foolishness in the author (I note that I am not offended. I do not crave your gratitude for my posts. Gratitude has a short memory, better to say what one thinks because one thinks it is right).

The literature of rhetoric and storytelling is way ahead of the engineering profession on this. I'm constantly amazed at how well the story theorists have turned the subjective into useful objective patterns that integrate so well with the way our brains are wired and influence us. Why do you think we will never forget:

The engineering profession should know more about this, especially as we attempt to program "higher" intelligence into computers. Further, high integrity systems are created by high integrity people. Looking into and defining what constitutes integrity in human behaviour is the sacred mission of us all, including the standards developer. So get on with it.

Most of us in standards want to be able to define something like the trustworthiness of a system, in this case with respect to safety or security properties, and we use the word "integrity" for it, because one has to have a word for it and that's as good as any. No one has yet succeeded in defining an objective property, in the way in which many people have succeeded in defining objectively what it is for code to fulfil its specification. I guess we shall continue to try until we succeed.

Participants here will appreciate at least in principle that my private chatter differs in style from my public communication. Mea culpa. I hope no one was offended.
