As some of you will probably know one of inspirations/origins for Scrum came from the article "The New New Product Development Game" by Hirotaka Takeuchi and Ikujiro Nonaka. Remarkably enough this article was written way back in 1986, incredible really as there are still companies out there that would look at the concepts presented in the article and call them "bleeding edge".

You can download the PDF from the Harvard site, it only costs 6.50USD..... The New New Product Development Game

All credit to the authors and indeed the companies being studied for having such vision all those years ago.
