You wrote it in 10 minutes ... but took you an hour to write
I think you are over-selling the importance of quick coding.
estimates that programming represents only 12% of
total software development cost while maintenance dominates at 67%.
So even reducing programming time down to zero saves you only 12%
while halving maintenance costs saves you 33%.
Of course, hacking out a quick throw-away script in ten minutes, rather
than an hour, is a big win.
But for production code that must be maintained by many different
programmers over a period of many years, it is more important
to focus on maintainability.
