Technodrone

Over all I think the best indication that someone will be a good agile
team member is:

• Demonstrates  a long-term desire to move from journeyman to craftsman. (study groups, software related blogging, seeks out training)
• Demonstrates that they will share knowledge insights with others.(mentoring,being mentored not just for newbies all team members)
• Open to debate and new ideas. (question whenever a quick solution does not follow solid principles, or adds unnecessary technical debt)
• Willingness to work closely with non-developers (users, business owners, managers)
• Patience with the process (complex problems are not easily solved it takes time and investigation).
• Can make the argument for refactoring code.
