I found this little nugget while surfing the “Selling Agile” Yahoo group (My emphasis added):
Lean/Agile is at it’s foundation, the fourth industrial paradigm, the first being Craft Production, Factory Production with machine tooling, Automation and Taylorism. These come along every hundred years or so and take a few decades to work through. Each paradigm includes the preceding one and makes it dramatically more productive.
There is no need to sell agile except to organizations that want to survive long term. If they don’t see the threat/opportunity they cannot succeed with agile or lean nor can they sustain economic viability in the long run.
