To be honest the worst mistakes in IT-management occur when you pick leaders based on technical skills over people skills. A good leader will listen to people and use a pretty well developed gut-feeling for when bullshitting is in the air -- hence the need for actual technical skills are of pretty low priority.
The absolutely worst train wrecks I've seen are honest and hardworking, guaranteed superb techies, who are elevated into management. They immediately start by 'merely' requiring everyone else to do what they're able to do themselves, which is a bloody disaster when you just kicked your best developer into a management position. To add insult to injury, your best developer material in an organisation are unlikely to be very good at handlig people -- they're too damn busy keeping up with being the best programmer to bother with being able to socialize.
