Do you think this would be beneficial for a somewhat perplexed CTO of a newly seed-funded startup? Or would it be wiser for me to concentrate on my current responsibilities and return to this book when my mind is clearer? I'm feeling a bit overwhelmed and under pressure, and I'm concerned that reading this book might add to the chaos. I would appreciate your input.
APoSD is a relatively quick high-signal read, and not really a source of additional chaos. You can get through it in a weekend or less.
It mostly gives you vocabulary and labels and explanations for things that you may already intuitively understand, and teaches you to notice small things that matter. It will probably make it easier for you to discuss and dissect some of the chaos you're already dealing with.
