I tried to pattern my career after An Unnamed Programmer in Peopleware, whose contributions weren’t always clear, but “had never worked on a project that had been anything other than a huge success.” She was overlooked by her management, so I learned that to do this, you needed to make your contributions clear.

As a manager, I didn’t always know how to hire for this quality, but I knew it when I saw it and made sure they were on the projects that mattered. And I keep track of them, too. I might not know if a new candidate is one, but once you know someone is a catalyst, you can always hire them at your next gig.
