That text is not devoid of merit. It's true that often when my coworkers are spending an unexpectedly large amount of time on a task, it's because they're getting sidetracked or being too stubborn to ask for help or, as the article describes, are way overthinking something.

But.

That's only generally a relatively minor problem; and the times when it's a major problem are rare.

What's a major, fundamental problem that regularly explodes in our faces is speed. Decision makers pushing for unmaintainable, barely functional crap under the excuse of pressing client deals and MVPs, and "go fast it's just a prototype I swear" that gets shipped straight to production and never gets cleaned up.

No, slowness is not the main thing you should be focusing on.
