The project manager should promote an environment where everybody knows what their contribution means to the project as a whole because this is the best way to have a highly engaged team. Agile projects are based on values and principles that emphasize collaboration, flexibility, and customer satisfaction, which require the team members to be motivated, committed, and empowered. Therefore, the project manager should communicate the vision, goals, and expectations of the project, and help the team members understand how their work adds value to the project and the organization. The project manager should also encourage the team members to share their ideas, feedback, and concerns, and involve them in decision-making and problem-solving. This can help to create a sense of ownership, accountability, and pride within the team, and foster a positive and productive work culture. The other options are not the best choices because they do not support the agile approach or the team engagement. Being clear with directions and assignments so people stay focused and engaged with their work (option A) may imply that the project manager is using a directive or authoritarian style, which may limit the team’s autonomy and creativity. Designing a reward system to get people motivated by recognizing significant individual contributions from the last sprint (option C) may help to acknowledge and appreciate the team members, but it may also create competition and conflict within the team, and may not align with the agile principle of valuing the team’s performance over the individual’s performance. Encouraging continuous rotation of roles among team members to keep people motivated throughout project delivery (option D) may help to diversify and enhance the team’s skills and knowledge, but it may also disrupt the team’s stability and efficiency, and may not consider the team members’ preferences and strengths. References: PMBOK Guide, 6th edition, pages 18-19, 52, 273, 335, 686-687.
