Limitations of the industrial manufacturing paradigm, including Lean and ToC.

Be careful how we apply industrial manufacturing paradigms, including Lean and Theory of Constraints(ToC), to IT. Linear stream flow models only work in IT (or, I suspect, manufacturing), at a close scale. Zoom out and they fail us, its not linear any more, not even to an approximation.

Why Theory of Constraints seems a poor model for IT

I am no expert but I worry that the Theory of Constraints is a bad model for IT.
Our systems are networks not linear flows. Mik Kersten's new book explores this.
