"Agile" is nothing more than a thinly SCAM by PMI, APM and PMO to "sell" training and certifications for a process that has been around for at least 6000 years (inventing the wheel) and probably going back 300,000 when our Neanderthal ancestors tamed fire, using what was known then as it is now, as being a "trial and error" method.
