Re: Hold on, if I read this right
read Brook's "Mythical man-month" and see what he says about the "second-system effect"
Let's not cherry-pick famous quotes.
Among the things Brooks actually says about "second systems" is
"The management question, therefore, is not whether to build a pilot system and throw it away. You will do that. […] Hence plan to throw one away; you will, anyhow.
I am fairly sure this is what was alluded to by "develop it twice".
What you have in mind is, I guess,
"The general tendency is to over-design the second system, using all the ideas and frills that were cautiously sidetracked on the first one. The result, as Ovid says, is a 'big pile.'"
This is also famous, but hardly applies to the topic at hand (it may apply to specialized NYPD app development - I don't know).
The quote that comes to my mind, however, is
"[An architect] knows he doesn’t know what he’s doing, so he does it carefully and with great restraint."
This applies, according to Brooks, to the first system. In the case of NYPD's "first system" knowledge of what one does not know was conspicuously absent while all care and restraint was, apparently, thrown to the wind because the phones were FREE.
