According to the PMBOK® Guide, the Develop Team process is focused on improving competencies, team member interaction, and the overall team environment to enhance project performance.

Co-location (Tight Matrix): This is a specific tool and technique of the Develop Team process. It involves placing many or all of the most active project team members in the same physical location to enhance their ability to perform as a team, reduce friction, and improve communication.

Training: This is another primary tool and technique for this process. Training includes all activities designed to enhance the competencies of the project team members. It can be formal or informal and is aimed at closing skill gaps to ensure the project goals are met.

Objective: The goal of Develop Team is to create a high-functioning unit. By using co-location and training, the project manager is actively building team synergy and individual capability.

Analysis of other options:

A. Acquire Resources: This process is about outlining and guiding the selection of resources and assigning them to their respective activities. It is the act of getting the people, not improving them.

B. Control Resources: This process is concerned with physical resources (equipment, materials, facilities, and infrastructure) rather than the project team. It ensures that the physical resources assigned to the project are available as planned.

C. Manage Team: This process focuses on tracking team member performance, providing feedback, resolving issues, and managing team changes to optimize project performance. While " Develop Team " builds the team ' s capacity, " Manage Team " focuses on their actual output and behavior during execution.

Per PMI standards, Co-location and Training are foundational techniques used to Develop the Team, leading to improved project results through better collaboration and enhanced skills.
