What percentage of projects are done using Agile methods?

Question

Are there any stats that tells about the percentage of projects done using Agile.. and further breaking down to XP, Scrum etc

Answer 1

Nobody knows because noone on those alleged projects bothered to document it.

:)

Answer 2

I don't know of any surveys, but they're run into a problem that I've called "cargo cult agile". They adopt a couple of "agile" techniques, and call it agile while working it back around to something like a normal waterfall.

Answer 3

Let's see, I googled "software development project survey agile"

And one of the first hits was http://www.versionone.com/agilesurveyresults.asp

Then, http://www.methodsandtools.com/dynpoll/oldpoll.php?Agile2

Then, http://agilesoftwaredevelopment.com/blog/martinig/third-annual-state-agile-survey-da

So, I guess there probably 145,000 results of the exact type you've requested.

Answer 4

Its 40.3%. And did you know that 84.3% of all statistics are made up on the spot? Fun aside, a quick google for "survey agile" gives you all information you will need.
