In this presentation filmed during Agile 2008, Scott Ambler talks about actual data resulting from surveys made during 2006-2008, showing how Agile is perceived and implemented within organizations. Some of the topics surveyed are: the adoption rate of Agile, the effectiveness of Agile approaches, the effectiveness of various techniques.
Watch: Agile in Practice: What Is Actually Going On Out There?(37 min)
Scott has conducted a series of surveys for Dr. Dobb’s Journal over the last three years on various aspects of Agile development. The results show how Agile is understood and used by people, how many are using Agile, what techniques they are using, etc.
Some of the results presented by Scott are:
Agile Development: A Manager's Roadmap for Success
VersionOne is recognized by Agile practitioners as the leader in Agile project management tools. Companies such as Adobe, BBC, CNN, Dow, HP, IBM, Sony and 3M have turned to VersionOne to help deliver greater value to their customers.
...and somewhat cultish.
Why said like that?
Our team management is changing to Agile, is there no difference with waterfall??

There is a difference. But, many organizations use Agile in waterfall way. The sad part is they don't know about it.
Can this link be fixed?
Overall, the first half of the presentation is a must-hear for anybody who is wondering why they should care about Agile/Lean.
Scott presents very interesting results of a Dr Dobbs 2008 survey:
THANKS!
PS: I completely missed the point with Modeling and TDD. Can anybody shed some light on this?
Having a look to the "Agile Project Success Rates %" slide there are 539 agile projects, which combined with the previous ones gave me a maximum of 125 companies (not hundreds by the way). I might miscalculated it, but if I am true, do you know any other report based on a higher number of surveys, please?
Cheers!
This recent news item points you to a recent, larger survey by VersionOne software. Their sample did include companies NOT using their software.
Sorry, not sure which link you mean. Please email me the url at deborah@infoq.com and I'll get it out there. Thanks!
I think Scott tried to relate or compare the concepts of Design using UML / Modeling techniques vs the generation of the Design by using Test Driven Development and Refactoring.
The basic idea in this sense is that before agile practices, the design was made by taking the requirements as input, applied some techniques and generate the design (and architecture) using models/diagrams as the main output artifact.
While if you use TDD, it comes that the design emerges as consequence of the continuous application and evolution of doing Unit Testing and Refactoring to the code you write.
Thank you Carlos. What is Scott's point regarding these practices in real life? Why oppose both techniques?
Specifying tests should not prevent people from creating some models? I agree that tests are more important than models, but models are still very often required as an aid to development, team members coordination and maintenance...
I guess I will have to listen to that part again... :-)
Olivier,
I believe the point Scott was making is that since the majority of professing agilists don't do TDD then TDD is not a good practice and the converse is true for modeling.
The person in audience questioned the validity of the survey because the majority of respondents do detailed documentation. In my opinion, that is a good question and Scott didn't answer it to my satisfaction.
Maybe Scott's point is that the agile practices that are not adopted by the masses should be cut?
Brian Marick takes us through a quick tour of the most important values and challenges to adopting Agile successfully (they aren't the typical challenges and values we hear in the community).
The line between development and architecture is tricky. Does it exist at all? Is an ivory tower actually needed? There's a balance in the middle, but how do you move from developer to architect?
The word 'authority' sometimes produces an allergic response in hard-line agilists. Freedom and authority – both are bad if misused and both are good if used in right spirit for a noble cause.
"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, and Taco Bell are all using Grails. Are you ready to get started as well?
Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. With ITIL V3, the focus of the framework shifted towards service-orientation.
SpringSource CTO Adrian Colyer discusses AspectJ, SpringSource's dm Server and tc Server products, OSGi and Scrum.
Heroku's Adam Wiggins talks about Rails, Background Jobs, Add-Ons, Ruby, and how Heroku manages to work around Ruby's inefficiencies using Erlang and other languages.
For Grady Booch the foundation of a good architecture is patterns, SOA being just one of many patterns. In this Second Life presentation, Booch attempts to bring more clarity on what architecture is.
