Over the years I’ve learned few things are more permanent than a temporary solution.
This is something your hear in a lot of places. Often (not always) it seems to be spoken with regret. I think we should be quicker to celebrate than a problem has been solved (and seems to be staying solved!) without worrying so much about whether it was done "properly".
Indeed, I think the frequent success of temporary solutions should be seen as a challenge to the prevailing orthodoxy that software developers should be striving towards more discipline and process. Instead, we should be looking seriously at why quick fixes and cowboy coding work so well, and asking whether we can apply these more widely.
