When building front-end software, it can be tricky to figure out just what works. As with any page layout endeavor, from the Web to the supermarket checkout line tabloids, there are plenty of nooks and crannies to explore with headlines, graphics, and colors. Any software shop earning money on the Web likely already knows about "A/B" testing: the practice of subtle changing your page design and gathering metrics on its effectiveness at converting visitors versus the existing version of the site.

Now that such testing regimes are commonplace in the enterprise, it is inevitable that every team eventually encounters the egregeous and exhausting existentialist crisis that is test management.
