I think the idea is not to do overtime. The idea is to use some of the slack you have because you finish your normal work early to consider process/architectural improvements or similar. Some people here consider it so obvious, that they even say it is part of your normal work. Well, I would say this mindset is much better than having worker bees who don't ever question anything and you end up with large inefficiencies because those who would maybe be empowered to define such work (like managers) don't have enough detail insights to actually do this.

I get the idea. I am not sure about the practical implications outside the individual advancements.

I have somewhat anecdotal evidence that the best production environment is composed of different people, in some part of your production you need "worker bees", and in architectural and research processes you need people with natural curiosity and experimental nature.

Even the author has some doubts of his argument in production.

>Shirking our Normal Work in favor of Extra might be more interesting, but it makes us shitty teammates at best, and unethical at worst.
