Computer science has a plethora of studies related to OS process scheduling. All of it is directly relevant to human task management. I've never, ever seen in referenced in any management talks/books/etc.
At work, I currently have 4-5 different PM's on 4-5 different projects. Each of them has no idea what the others are asking, and I am constantly bombarded with one off tasks via hipchat or in-person requests. The point is not to complain about work, but to agree that management would do well to recognize the importance of process scheduling and queueing, and that a failure to do so is only detrimental to their own objectives.
I don't have _that_ many PMs, but when I have multiple people asking me to do simultaneous tasks, I email all of them, asking them to prioritize the list for me. I'm polite about it. And it mostly works out. But I never, ever shy away from doing this.
I've read it. It was an easy read. No mathematics. Every occurrence of "NP-complete" was replaced with "intractable" and there are tons of anecdotes, many I hadn't heard before. I didn't come away from the book feeling profoundly altered, but I didn't regard it as a waste of time either. If you're looking for something to read on the train, this will do a solid job.
Sometimes you encounter a book that covers material you already "know", but seeing it in a sort of coherent narrative structure can be the thing you need to change the way you think about and perceive the world.
Don Reinertsen mentioned it. At least in a talk, and maybe in his book "The Principles of Product Development Flow".
That's only 1 example, but in my personal estimation he's one of the two most effective management theorists I know. Though I wish he were a better explainer. (The other of course is Shanley Kane.)
If you're an engineer and have trouble getting past project management methodologies that feel like bullshit (or conversely if you care a lot about them but have trouble convincing your team to) you must read "Principles of Product Development Flow".
It's definitely a pretty dry read in parts, but battle through it.
Thank you. I couldn't remember the name of the book or the author. There's a lot of queuing theory in the book, along with the mathematical conclusions (eg 100% utilization = arbitrarily long queue times). Fantastic book, I think I'm going to have to make sure it's on the kindle for some upcoming flights.
