This article is too unscientific. It mostly regurgitates non-scientific professional literature, while ignoring relevant research. I'm going to add some research. If any agilisits out there take offence at my changes, please read the research before reverting anything.Paul Ralph (University of Auckland) (talk) 12:49, 5 February 2018 (UTC)
Please note that this content has been moved (rather than deleted); it is not significant enough in its own right to warrant being in the lead / lede paragraph. Also, the link you posted is to content behind a paywall; it's a bit hard if other editors are challenged to read this before they can challenge this edit. As it happens, my masters research topic was whether Agile Transformation worked or not, in which I referenced a paper by Dingsøyr which argued that agile practices do in fact help. I will reach out to you offline to suggest meeting up to discuss (as we know each other). Davidjcmorris Talk 02:23, 7 February 2018 (UTC)
I never said that agile practices were devoid of benefits. There is, for example, evidence that Scrum increases productivity. I said there's no evidence that they increase agility. There are no validated measures of team agility, and you can't demonstrate a causal relationship on a dependent variable you can't measure. The fact that all these practices are called "agile" without anyone ever demonstrating that they increase agility is possibly the most important thing you could know about agile. It's like pfizer selling "cancer drugs" that don't fight cancer, or "anti-virals" that don't kill viruses. It's a "productivity practice" that doesn't increase productivity. It is very common on Wikipedia to point out the lack of scientific evidence supporting a thing in the introduction. And you don't get to discount research that's published behind a paywall.

Can you clarify:
* What are you meaning by agility? Common uses included: Hypothesis driven experimentation, trying out ideas on a small scale. Early delivery of value (whether to customers / end-users or to the product owner / development team). Fast feedback to uncover change early and avoid too much investment in scope not required. The ability to absorb change without causing additional cost, by dropping lower priority scope. Etc. There is evidence that this happens.
* What you mean by scientific evidence? As Popper and others have said, it is hard to scientifically prove a hypothesis; so a theory should stand until there is evidence that disproves it. There is, however, an abundance of research in this field, following a wide range of research methodologies. Which methodologies would you regard as scientific and which not?
Incidentally, the research was not questioned, but rather the insistence that people read it before challenging the edit. The offer to discus the article and points raised in person still stands (I have emailed you separately about this). Davidjcmorris Talk 01:26, 12 February 2018 (UTC)
Your conclusion about testing being performed during development as an agility indicator is false. Often testing happens at the end, but doesn't indicate agility 1 way or the other. What people call "Waterfall" now-a-days also had testing in it at various points along the dev life cycle (why "waterfall" is a misunderstood/derogatory misnomer). — Preceding unsigned comment added by 2603:9001:2708:7091:6C87:D82F:9846:8ADD (talk) 16:40, 9 August 2019 (UTC)
Missappropriations to unpublished manifesto: Is this an urban legend?
User:Paulralph You said, "...evidence that Scrum increases productivity...". Who has investigated this and where did they publish the result?
This article misapproriating the iterative development and evolutionary management as part of Agile. What is the connection? This is border line to 'fake news'. How can one appropriate former formal works from IBM where they are published to a unpublished manifesto? So called "Agile Manifesto" is a web document. To be honest, "agile software development" seems a bit of an urban legend went to main stream but no body knows what is it and anything and everything is agile. Unacceptable quality for a wikipedia article.
I propose to change article name to "Agile movement" as this is a movement, as in social movement. This can not be presented as a development methodology as it did not grow out scientifically but a socially.

That probably requires a request for comment. Please get consensus before making large scale changes. Thanks. Guy (Help!) 22:37, 1 September 2019 (UTC)
