[SystemSafety] Collected stopgap measures

[Peter Bernard Ladkin]

I find this emphasis on some "proper" way to collect reliable statistics on the effectiveness of
software development to be a little odd. Barry Boehm has written two rather large books, one 37
years ago, and a follow-up a couple of decades later, establishing some basis on which companies can
obtain useful objective quantitative information on their software development processes.

None of them involve performing experiments of the sort Derek Jones is advocating, where you have
lots of teams developing software for the same task in parallel and then comparing results. That
seems to me, if I may say so, a pretty stupid way of getting such information. Besides, it was shown
by Knight and Leveson decades ago to be flawed.
