Jazz bands come together through voluntary associations of individuals who recognize complementary capabilities. They then practice together to build up their skills and more importantly to build a tight team where everyone knows what everyone else is doing or is about to do. A jazz band is only hired after they have practiced to the point of being able to demonstrate they can do the job as a team. When hired, the band is hired as a all-or-nothing band. We don’t hire the drum player of a successful band to fill our drum-playing vacancy. Instead when we encounter a situation where the currently hired band lost their drum player, we replace entire with a completely different band that does have a drum player.
I imagine this approach can offer a solution to the problems of the modern job market. Instead of recruiting individuals, we should recruits bands or squads of individuals. The individuals have trained together and come in as a team. As soon as a team lacks any key player, the entire team is replaced with another team.
