Which tool is used to define relationships between deliverables and activities?

The PERT Chart, or Program Evaluation and Review Technique, is specifically designed to illustrate and analyze the relationships between various activities and deliverables within a project. It allows project managers to visualize the sequence of tasks, their durations, and how they interconnect with each other. By depicting these relationships, a PERT Chart helps in understanding the critical path of a project, which is vital for effective scheduling and resource allocation.

The other tools mentioned serve different purposes. Team collaboration software focuses on improving communication and coordination among team members but does not inherently define relationships between tasks. A version control system is used for managing changes to source code and tracking revisions, which is unrelated to project deliverables and their activities. A code review tool assists in inspecting code quality and ensuring that coding standards are met, rather than mapping out the relationships between project activities and outputs.

Thus, the PERT chart stands out as the appropriate tool for establishing and visualizing connections between deliverables and activities in project management.
