This bit of your comment reminded me of The Goal: A Process of Ongoing Improvement by Eliyahu Goldratt. It's a great fictional story/book that does an excellent job of teaching about bottlenecks and the Theory of Constraints. Specifically how to identify them and eliminate them.
For anyone interested in 'systems thinking' and associated optimisations, check out the 'Implementing Lean' book:

I have to say, there's way more wisdom in the more mature 'lean' world than there is in the trendier 'agile'.
