So, cynically, (and I say this with no disrespect intended to the author directly): a screed about how to continue justifying your existence as a—ostensibly "good"—middle manager (using, as its basis, one of the most nausea-inducing jargon terms to ever claw its way out the semi-sentient Dunning–Kruger ooze that is corporate-speak.)

And, to be clear, I do actually think a good middle manager is beneficial, if most commonly in the way of any necessary evil, as a very effective grease for the oft poorly meshing cogs of business. Not unlike the fresh breeze of an actually effective project manager or personable AND productive engineer.
