Here’s the thing: the hero is the most damaging person on a team, particularly on a team that’s supposed to be writing high-availability or otherwise mission-critical software. ​ The hero is a human patch. ​ When a team can rely on a hero, they don’t need to grow and learn collectively. They don’t need to get better. They can coast along, which serves no one in the end. ​ You’re clearly managing someone highly motivated, but you need to shape that motivation into something more constructive.
