Glenn Parker identifies four types of team players, one of which is The Challenger. The Challenger is known for looking at the bigger picture and often asking questions about the goals, methods, and ethics of the team. They encourage the team to take calculated risks and are willing to disagree with authority when necessary. They play the role of the Devil’s Advocate by being honest, outspoken, principled, ethical, and adventurous, challenging the status quo to foster improvement and innovation within the team. References: = Parker’s description of team player types and their roles in effective teamwork1.
