Context switching is expensive. I agree with the strategies you shared for better managing time, but you seem to be interpreting the article as literally manager vs maker, as if there’s a strong adversary between the two, when in reality, an engineer who’s expected to attend all the meetings and also be able to turn around designs and code is just not going to be as effective because of the high cost of context switching. The authors point stands.

Somehow you managed to see the worst in this, making the article about yourself, and you even accused the author of purposely misleading to sell his or her product. If you’re a manager, I would encourage you to be more open minded, for the sake of your employees if nothing else.
