When it comes to software testing, people disagree quite a bit. Some argue vehemently for a particular point of view, while others consider that very position nonsensical. For example, the "zero defects" crowd generally thinks the "good enough quality" crowd is out to lunch -- and vice versa. The different camps have different pictures in their heads, different frames of reference and implicit assumptions. A big part of what's important in debates about software testing (and, by extension, software quality) is what goes unsaid because the speaker considers it obvious.

IT and other operational managers often dislike the idea of outsourcing activities in their areas of responsibility. The reason for this seems pretty clear: outsourcing invites the possibility of added complexity, loss of control, and operational risk. Of course, outsourcing can result in all these things. But it has been a long time since most businesses were completely vertically integrated -- that is, since all company activities were performed internally.
