There are plenty of job descriptions that make you scratch your head, wondering what they are really looking to hire. The classic is the job requirements for "good at multitasking" when that can be exactly the wrong trait. I came across one that throws Theory of Constraints and cost reductions into the same set of requirements.
I came across the video from the University of Texas 2014 Commencement address by Admiral William H McRaven in which he describes his training and draws ten life lessons. The story is engaging, and while the lessons out of context sound odd, they make sense in the way he puts it together.
"The CIO's Guide to Breakthrough Project Portfolio Performance: Applying the Best of Critical Chain, Agile, and Lean" by Michael Hannan, Wolfram Muller, and Hilbert Robinson is a good, short description of how to take ideas from several disciplines and apply them to an overall portfolio management approach.
