> I don't know about anyone else here but I've working on many, many successful software projects that have made their owners many millions of dollars with out-of-date or missing documentation, minimal instrumentation, and minimal or no dashboards to speak of. Most projects I've worked on have achieved at least some level of commercial success and the vast majority missed at least one of those major categories, usually several.

Since we're being pedantic, plenty of software projects that have made their owners many millions of dollars have subsequently failed. Who uses WordPerfect or Lotus 1-2-3?
