- 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.
