In Agile project management, the role of the leader shifts from " command and control " to support and facilitation. This philosophy is encapsulated in the concept of Servant Leadership.

Why Choice A is correct:

Empowerment: Servant leadership focuses on the growth and well-being of the team. By putting the team ' s needs first, the project manager empowers them to make decisions, which fosters the commitment and motivation mentioned in the prompt.

Removing Impediments: A servant leader’s primary job is to clear the path for the team—removing " roadblocks " or " impediments " —so the team can focus on delivering high-value work.

Agile Alignment: The Agile Practice Guide (developed by PMI and Agile Alliance) explicitly recommends servant leadership because it promotes self-organization and accountability, which are the engines of Agile delivery.

Characteristics: Key traits include listening, empathy, stewardship, and a commitment to the professional development of team members.

Analysis of other options:

B (Laissez-faire): This style is " hands-off, " where the leader allows the team to make all decisions without much interference or support. While it offers freedom, it lacks the proactive support and guidance a servant leader provides to help a team succeed.

C (Collaborative): While Agile leaders are collaborative, " Collaborative Leadership " is a general management term. " Servant Leadership " is the specific, recognized framework within the PMI-ACP and PMP domains for Agile projects.

D (Directive): Also known as " Autocratic, " this style involves the leader telling the team exactly what to do. This is the opposite of empowering the team and is generally ineffective in Agile environments where self-organization is required.

Key Concept: The Project Management Institute (PMI) emphasizes that in Agile, the project manager (or Scrum Master) does not manage the people, they manage the environment. By adopting a Servant Leadership style (Choice A), the leader creates a safe space for the team to experiment, learn from failure, and ultimately take ownership of the project ' s value delivery.
