Colvin, IMO, is wrong. Most likely he never worked at the intersection of mechanical complexity and physical suffering, and so never had skin in the game.
There is a technical aspect of a job, and then there is the feel for the job, and finally there is the gift for the job.
Industrial jobs are broken down into technical parts made as simple as possible so that the greatest number of employees can fill the technical function, which drives down the cost of labor and decrease hiring headaches.
But only a subset of people will have the feel for the job. People with the feel for the job are the ones that can predict trouble and avoid it before it happens. They can improvise solutions for problems because they intuit how everything works together. They get the why of the job and not just the how.
But more than just having a feel for the job they can somehow infect the rest of the crew with their own enthusiasm, just like certain crew members can drag down the tone of a crew with their carping and malingering.
The gifted ones are at yet another level. They learn the technical aspects overnight. They reach a level of productivity it takes the mere technician months or years to master, and they best everyone at the process. They quickly intuit how the whole picture works, and have an innate desire to polish the process to artistic perfection. They wake up at 0400 wondering if anything was left undone, and have bizarre dreams of how to do things better.
It’s no different than sports. You can teach anyone baseball. But you can’t teach a feel for the game. Play it enough and your technical skill might make up for lack of the feel, but you’ll never really get into the groove of a great player. That’s ok. There are not enough players in the world to make every team great.
Then there are the great players. They were born that way. Sure, they had to practice to reach greatness, but you could pretty much pick them out in Little League. One thing that separates them from the pack: they have this innate ability to get the everyone working together as a crew.
Every team, every crew, is going to be a mix of these types. Each type has their role. Where I work the ones with a feel for the job we call Sparkplugs. They make the engine run. Ideally, the gifted ones rise from the ranks to become captains/chiefs.
If you don’t aspire to greatness in a team you don’t need great players. But that means your team will be, by definition, mediocre
