According to the PMBOK® Guide, Co-location (also referred to as " tight matrix " ) is a specific tool and technique used in the Develop Project Team process.

The rationale is as follows:

Definition: Co-location 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.

Purpose: The primary goal is to improve communication, reduce conflict, and help build a sense of community. By being in the same room, team members can utilize informal communication channels and develop stronger working relationships, which is the core objective of the " Develop Project Team " process.

Distinction from other processes:

Develop Human Resource Plan (Planning): Focuses on identifying roles, responsibilities, and reporting relationships.

Acquire Project Team (Executing): Focuses on gaining the human resources necessary to complete project assignments.

Manage Project Team (Executing): Focuses on tracking team member performance, providing feedback, and managing changes to optimize project performance.

While co-location may influence how a team is managed, the act of physically bringing the team together to foster development is explicitly categorized under Develop Project Team.
