PDC 2008: Architecture without Big Design Up Front


(I lied. I didn't make it to the Oslo session.  I went to the "Big Room" and spent tons of time getting swag and talking to vendors.  I also spent lots of time with Peli talking and learning about PexPex looks to be a very compelling whitebox testing platform.  I suggest you take a look into it.)

 

So now I'm in the Peter Provost talk.  I read his blog but I've never seen any of his presentations so I'm really looking forward to this one.

 

  • Good Architecture is about communicating design.
  • All systems have an architecture whether you plan it or not.

The crowd seems to be mostly "Agile" (we figured that out by the standard "Round of Applause" methodology.  I think they are lying or don't know what "Agile" really is.  Just an opinion.)

  • Most Architectures are "Big Ball of Mud"
  • Architecture is about ending system that is better than with what you started with.
  • Architectural Discovery
    • Everyone has existing code bases
    • Key architectural elements are undocumented
    • Maintenance is hard
    • Changes expensive
  • We are going to use the CTP bits of Architecture Explorer on Rawr (Check on CodePlex for it)
    • Cool project dependency diagram
    • Project dependency graphs have multiple views
    • Can create class dependencies also
    • Sometimes it's good to look at the pictures that are generated in the diagrams instead of trying to look for patterns that will show you key types in the solution/project
    • Drilling into what looks to be key types you can find code and method level relationships
    • Architecture Explorer supports Sequence Diagrams, Very cool. Johanri (my coworker) will love it. He's an UML guy.
  • Using Architecture Explorer is about viewing the system, not generating tons of diagrams for BDUF
  • Oslo == Executing Models, Architecture Explorer == Communicating Models

Battery is about to die again. Time to shut-down.
