The basic response was something along the lines of &#8220;you just don&#8217;t do that.&#8221; Lovely. A powerful and productive technique that you &#8220;just don&#8217;t do&#8221; because the methodology you have required people to adhere to does not allow for it.<\/p>\n<p>And what if programmers sometimes come up with better ideas on their own? Sorry, no can do, either. Pair programming doesn&#8217;t allow for alone time.<\/p>\n<p>&#8220;Sorry, we&#8217;d like to incorporate that feature change, but we&#8217;ve frozen the feature set because the software is now in alpha test. We just can&#8217;t do that.&#8221; Funny how the supposed diametric opposite of the traditional waterfall model ends up sounding so much like it.<\/p>\n<p>The problem here is one of taking rules too seriously. <em>Any<\/em> set of rules \u2014 it fundamentally does not matter which ones. You cannot fix such a problem merely by choosing the right set of fixed rules, no matter how enlightened the motivation behind the choice of them might happen to be.<\/p>\n<p>If you can&#8217;t make exceptions for exceptional cases, you&#8217;re going to end up sometimes forcing people to act like stupid robots, doing something suboptimally because that&#8217;s the only way The Rules allow for it to be done.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I think that, ironically enough, it can.
