No. As Tufte pointed out, those engineers produced poorly analyzed
chart-junk filled graphs which obscured rather than helped reveal the
meaning in the data. They could have instead easily produced an
informative graph which would have helped illuminate the known and
very severe risk of O-ring burn through. They did not, and indeed,
the graphs they DID generate were WORSE than useless.
That was an ENGINEERING failure, and not one that would have been
helped by any class on what is colloquially known as "presentation
skills". A serious, hard-core treatment of graph and information
design, yes, that could have helped. "Presentation skills", no.
Engineering problem with the seals, certainly. The presentation skills
would have helped the engineering management system "do the right thing",
i.e. wait 'til it got warmer to launch.
On Columbia, it's uncertain that any amount of analysis and presentation
would have helped during the actual mission. You've got a big hole, and
not a heck of a lot you can do about it, although, a lot of people would
have been mobilized to try and come up with ideas.
To a certain extent, it's like having a lame horse and deciding whether to
spend $500 to call the vet out and do X-rays. The vast majority of
lamenesses are treated in exactly the same way, light work and
antiinflamation drugs for 6 weeks, so there's not necessarily much value
added by knowing exactly why the darned beast is lame.
Knowing why the hole in the wing exists is useful for future missions,
because you might be able to prevent it, but doesn't much help the folks
with the hole.
