      I've been thinking more on that whole Agile Architecture thing ... here's
      some ramblings on the subject to spark debate.

      am a bit frazzled by the term "Software Architect." I don't think it means
      anything. <http://www.ddj.com/architect/184407745>

      Or, perhaps, to put it another way: Perhaps it means everything?

      The confusion of the word reminds me of the confusion over the term testing,
      which reminds me of Brett Pettichord's Four Schools of Software Testing.

      It occurs to me that there are at least five distinct schools of computer

      CPU Architecture: Highly specialized and different; slim to never confused
      with the items below
      A CPU Architect looks a lot like: An electrical engineer
      Exemplar: Multi-Core CPU's

      Systems Architecture: Interested in the technology stack used by the
      business � for example � HP/UX servers running Oracle as DB servers, linux
      web servers, desktop PC's with windows
      A systems architect looks a lot like: A director of IT services
      Exemplar: Service Level Agreements, Redundancy, Failover, Backups

      Software Architecture: Interested in implementing various strategies to
      solve problems, such as Session, State, Domain Logic, Polymorphism, MVC, and
      so on
      A Software Architect looks like: A highly-abstracted programmer
      Exemplar: UML Diagrams

      Organization Architect: Interested in how to seamlessly integrate people,
      processes and tools while speaking a common business language
      A Organization Architect Looks a Lot Like: A professional design-reviewer
      Exemplar: The Zachman Framework, "Enterprise" Architecture, The City
      Planning Analogy

      Consulting Architecture: Interested in helping the customer and technical
      staff reach a shared understanding of the work, breaking the work up into
      manageable chunks, helping the customer understand the solution, and
      sticking around to see the solution implemented.
      A Consulting Architect looks a lot like: What we used to call a 'systems
      analyst' in the 1980's
      Exemplar: Story-Cards and a release schedule

      This is really just a conceptual framework. Thus, when I get into arguments
      about the meanings of the word "Architecture", I can say "Oh, wait, you're
      coming from the consulting school" and do translation. (This can explain a
      lot of the conflicts I've gotten in where, for example, I realized a
      consulting architect wasn't really technical or an organizational architect
      stood up and said "This isn't really an architecture question" and stepped
      out while we were planning the systems infrastructure.)

      But what do you think?

      "Objectivity cannot be equated with mental blankness; rather, objectivity
      resides in recognizing your preferences and then subjecting them to
      especially harsh scrutiny � and also in a willingness to revise or abandon
      your theories when the tests fail (as they usually do)."
      - Stephen Jay Gould
