It all comes down to sales being easier to measure than other parts like development.  Something like &quot;doubling revenue&quot; can be reasonably objectively measured.  Trying to do the same thing for a developer is way too hard: double X? halve X?  where X is lines of code, bugs, hours of attendance, appraisal scores, or other measurements don&#x27;t remotely cut it, and are easy to game.  (Revenue can also be gamed to some degree, but people&#x2F;companies parting with cash is a higher hurdle.)<p>That let him make a measurable deal with Gates &amp; Allen.  A new developer as employee #30 doesn&#x27;t have anything comparable.
