Hasn't been mentioned in the thread yet, but the Phoenix Project is also excellent for senior engineers/managers.

I read it once when I was a junior engineer and didn't get much out of it, then again 6 years later and it was _excellent_.

I recommend The Goal as another reading, I think it does a better job on covering the Theory of Constraints aspects compared to TPP, but TPP does a good job of connecting that idea to IT work and software development.

Goldratt's sequels to The Goal are worth a read, too, but The Goal covers the more critical parts (IMO).
