Sigh. This article is obviously completely correct, but I don't think the people who actually need to read it will care.

Running anything at constant 100% utilization means you are going to be working in crisis mode all of the time. Even in factory labor, the Toyota Way is several decades old now, and it involves making sure everyone has at least a little breathing room to step back and think about what they're doing. And obviously this is even more important for "knowledge workers" or anyone whose output requires any amount of creativity.

High functioning organizations have a good (not too much, but not too little) amount of slack in their work pipelines. Pretty sure there is not a single person with an MBA (or, lol, any consultants) that knows this anymore.

Yeah, same sentiment here. I agree that some more people need to be told to relax a little in our field, but on the other side, the product and project managers are constantly looking to ensure maximum utility, especially in startups and high pressure environments. And looking around with the large number of companies that laid off people in the last year or two, I see fewer devs having the choice to push back when that happens. It really reads like the author is in the comfortable position of a staff or principle engineer without a direct manager and gets to decide what their day and week looks like and pick what they work on. I am afraid fewer and fewer have that luxury...
