What makes you think that software engineering, or system
engineering, has progressed to the point that a software intensive
system would be developed "with proper discipline"?

That's fair enough. Software, perhaps more than any other discpline,
allows engineers to place themselves where they are most comfortable
on the spectrum of intellectual discipline.
[...]
In any case, while process is important, the end result is most
important. And the end result would be seen by many people, before
the aircraft is flown, so most defects would be recognized. I would
imagine that there would be people who would criticize the
architecture for free.

From the perspective of dealing with software development for about
a quarter century now, all I can say is that it is obvious you know
**** from shinola about software development, reliability, and
testing.

Well I've been programming for 35 years and been getting paid to do it for
30, so by your own metric I am presumably in some sort of authoritative
position to judge your counter arguments to Lapin re software development.
But I somehow doubt you really want to know what I think of your arguments.
;-)

Have you ever known reliablility and correctness testing to be either
easy or cheap, particularly when dealing with life critical systems?

No.

I now think I probably shouldn't have entered this thread. My own ideas
about system development don't appear to agree with either the idealistic
and inexperienced/naive views expressed by Le Chaud Lapin or necessarily
with your hard earned cynicism. Well, cynicism doesn't quite contain the
nuanced meaning that your real position probably entails, so forgive me
that it doesn't characterize your full position.

I think I might have argued from a different perspective than you, or at
least used a different set of arguments, not that I nessarily disagree with
your general thrust. I wouldn't, for example, have used some the anecdotes
you used - which for some reason bothered me, but in retrospect it isn't
like any of us get paid to insure every post is rigorously logical!

I'm a bit on edge at the moment as I am deeply involved in testing a
system due to go live in a couple of days which if it goes tits up
will embarass a lot of people and cost me a lot of money and if it
works means a huge amount of follow on work.

So while test cases run I have a far amount of thumb twiddling time
to play USENET.

Exactly, not to mention the fact that anything past the most simplistic
of arguements and examples are going to fly right over the head of
Le Chaud Lapin.

Sounds like fun. ;-) Seriously though, I wish you good success.

Thanks.

A bunch of major tests just finished with zero problems.

Things are looking good...

In my experience, a test that finishes with zero problems is a failure.

I never said it was the first set tests...
