Many people assume that agile methods mean an absence of design. Design still happens in agile projects, but it shifts from an up-front phase to a continual evolution. Design decisions should be left to the last responsible moment, but some design decisions do need to be made at the start of a project. At the last QCon, Martin Fowler explored this topic through a panel discussion of design in an agile context.

Watch: Modifiability, or is there any design in Agility (58 min)

This panel was recorded at the Architecture Qualities track at QCon London, there will also be an Architecture Quality track at QCon San Francisco in a few weeks.  This topic was also explored in-depth in previous InfoQ Coverage including Are Agile Development Practices Detrimental to Architecture and Design, and Making Agile Methods and Enterprise Architecture Play Nice.

   I really enjoyed this Panel @ QCon london, I ve been waiting for this video for almost half a year now! Also another video i am expecting soon is the "The Yawning Crevasse of Doom" keynote with Fowler and North.

   To watch them offline, is there a way to download the videos and presentations?

   Yeah, would be really nice. I always get problems watching videos on InfoQ, for some reason - the video "gets stuck" after 10 to 15 minutes of playing, and the only fix is to stop it, start from the beginning and drag the playback icon to the place it got stuck.
   
   Well, today this fix just doesn't work. Perhaps because I'm using Safari on a Mac? Anyway, this is too frustrating, so I give up... which is a shame, because the panel discussion seems really interesting, and I've enjoyed the 25 minutes I succeeded watching.

   Am missing that as well. Would like to share it with my team on a big screen.

   Sorry guys, we are working on a new system that will make some of these problems go away, but it may not be up for another month or two. In the meantime there is now way to download these or go full screen. MP3 versions should be added later on as well.

   I have been creating custom software for 25 years and I now feel less
   lonely on Earth.
   
   Since I started to write software, I used to postpone decisions until time was up
   to address them, I used to design evolution capabilities in my design, I used to
   understand the business model and simulate processes to insure my software could bend
   to potentially new uses not in the immediate scope of the project at hand,...
   
   And I never has to use a book about design patterns to find the appropriate one...
   
   I never understood "architects" these days to spit out
   tons of papers describing the system down to the tiniest bolt before spitting out the
   first line of code. We have much more powerful tools now to refactor software than
   just a text editor, a compiler and a linker...
   
   To me it looks like bullshit to postpone the implementation as much as possible.
   It's code that makes a system run business processes, not the paper around it.
   
   I saw many "so called architects" adopt a rigid design from the start to end up failing at user acceptance
   tests, busting budgets, missing time to market deadlines, or ending up with a solution that is not flexible enough
   to adapt to new business needs. This happens too often to be anything else than
   a bad approach to creating software systems.
   
   These "so called architects" leave projects just before failure
   and propagate their bad practices elsewhere.
   
   It's about time that the industry rethinks it's approach to creating softwares.
   It looks to me that we went through a creativity drought for several years
   were software projects were assimilated to mechanicals processes that were to yield a
   working implementation. Experience in delivering projects from 0 to production is
   not recognized since the belief in these mechanical methods to deliver software is
   deeply anchored in the industry.
   
   Creativity and experience are essentials in a project. Since the parameters are never the same (time to market, budget, business domain, ...) there is no single recipe that can work for
   every project. Nonetheless that mirage of a bureaucratic process has been sought
   by the industry for years and I think it relegated creativity and experience to limbos.
   
   Hopefully, the wind will change sides...

    For me it gets to a little after 46 minutes, then jumps to 0:00 (black screen with play button).

    After reloading the page it gets to 58:21 - the full length of the video, but not quite the end of the session.

    semantics

    by joshua milane

    How is an insurance policy waste? I think semantics are getting people confused, or waste is not really waste, or people are choosing their words poorly.
