Well that's just the thing - an organization that has a "system" or "process" for handling employees and their work is by design less than flexible. In a small to medium sized business, you might have 3 completely separate roles, and others might pitch in as needed. But at a large corporation, it's simpler and more efficient for them to have one person who does one job. When the peg no longer matches the hole, they are replaced or reassigned. Which is sad, because people with valuable skills are often underutilized. I feel like companies like Valve might have the right idea going forward.
