> Scrum is iterated waterfall. No, it isn't. Iterated waterfall is at least as old as the first paper discussing waterfall, but while scrum mandates interations, it doesn't mandate much about how work is done in the iterations, and specifically does not mandate the process steps associated with waterfall; further, it emphatically rejects the role separations and handoffs associated with waterfall during the iteration…
What percentage of Scrum teams do you believe are "properly cross-functional and self-organizing"? And could you point me to examples of people losing their Scrum certifications for not living up to that standard?
About the same percentage as that of “Agile” software development shops that put people and interactions above processes and tools.
OTOH, at any place that is considering implementing either, there are decision makers who can influence (or in the case of Scrum more than Agile, authoritatively direct) whether or not that's the case, so for them, at least, it's worth distinguishing between problems with Scrum as prescribed and problems which often occur because decision-makers decided to ignore key parts of Scrum-as-prescribed.
