Stewart did read the modern literature. He might have. He didn't quote any of it.

  He does, in fact, quote and cite multiple sources. Michael Porter. Marvin Bower. James C. Worthy. Tom Burns and G. M. Stalker. Tom Peters. Gifford Pinchot. Karl Popper. Perhaps not modern enough for you, though works through the 1990s are mentioned. None are "century old". Not at the time Stewart wrote, not now. How about you assert what specific sources are missing?
