Scrum is an agile process that allows us to focus on delivering the highest business value in the shortest time……It is iterative and incremental…… (from Mike Cohn)
Open mind, active exploring, willing to share and help others. Experienced in transformation or at least understand political ego-system of organization, be good at using power w/o eager to that. Above average level of technology and product knowledge. Have communication and influencing skill. More of extroversion.
