        Nice list Ron, thanks for sharing that.  I'd like to see something more specific about Courage and Risk-taking on the list, and think maybe Confidence is absorbed by Supportive Culture.  That'll keep it to seven things :-)

        There's no doubt that the certification has been a brilliant
        marketing scheme. (And the course is a good one as well ...
        especially the way Chet and I teach it.)

        However, it's well known that XP-style practices are very important
        to doing Scrum well, and there is, in addition, an upswelling of
        interest in technical practices as part of what a developer should

        There is a lot more than just some designing and coding and testing,
        however, to being an effective team member. A few of us have been
        talking about the dimensions of quality of an Agile developer and
        have come up with these:

        Product Sense -- understanding of the domain;
        Collaboration -- the ability to work skillfully as part of a team;
        Focus on Business Value -- steady flow based on business priority;
        Supportive Culture -- experiment and improve, never blame
        Confidence -- growing certainty and clarity about what is done;
        Technical Excellence -- solid software build sustainably;
        Self Improvement -- learning and sharing, team and individuals;

        As you can imagine, a focus on these amounts to a lifetime
        commitment. And that is as it should be.
