This article, posted on Oikosofy’s blog, gives a pretty good introduction into the way things were in manufacturing and the way things are now. In “Agile-Manager — What is an Agile Manager?” he goes back to the time of FORD to explain how things have progressed.
It shows that not only have agile methods changed the way things are made, but they have also changed the corporate environment which houses the teams who make the products.
He also address how so many businesses now offer services and how that effects development.
I found this article insightful and worth a read.
