Martinig & Associates Methods & Tools group recently updated their agile adoption survey and compared their results to their initial inquiry back in 2005. They asked a single question: "At what stage is the agile approach (XP, Scrum, FDD, ...) adoption at your location?" The results indicate a two-fold increase in awareness of agile methods (26% in 2005 to 13% in 2008 not aware if agile methods) and a two-fold increase in all projects deployment using agile methods (8% in 2005 to 17% in 2008). The complete results are shown in the table below and can be found on their website.  I have summarized the data in the chart below...

Is this good news? While their findings show that agile awareness and adoption are on the rise, their findings also come with a warning...

"The recent improvement in agile software development process visibility and acceptance should however make us cautious with the current results on agile adoption surveys. When software development practices are more widely accepted, the number of adopting organizations increases, but the substance of valid usage of this practices decreases. The answers to surveys tend then to be biased towards what should be the correct answer instead of reflecting the reality of the software development context. The tendency of upper management to "push" new approaches to people who are more reluctant to change their old habits does usually not produce good results. This is even truer when projects will not be given additional resources to support the transition."
