Which grid shows which resources are tied to work packages?

In accordance with the PMBOK® Guide (Project Resource Management), the Responsibility Assignment Matrix (RAM) is a grid that shows the project resources assigned to each work package. It is used to illustrate the connections between work packages or activities and project team members.

Function: The RAM ensures that there is only one person accountable for any one task to avoid confusion. On larger projects, RAMs can be developed at various levels. For example, a high-level RAM can define what a project team group or unit is responsible for within each component of the WBS, while lower-level RAMs are used within the group to designate roles, responsibilities, and levels of authority for specific activities.

RACI Chart: The most common type of RAM is the RACI (Responsible, Accountable, Consulted, and Informed) chart. In a RACI chart, the work is listed in the left-hand column as activities or work packages, and the resources are listed across the top as individuals or groups.

Analysis of Distractors:

A. Work breakdown structure (WBS): This is a hierarchical decomposition of the total scope of work to be carried out by the project team. While it defines the work packages, it does not inherently show the resources assigned to them.

C. Project assignment chart: This is not a standard PMI term. While " Project Team Assignments " is an output of the Acquire Resources process (documenting that the team is in place), it is not the grid used to map resources to specific work packages.

D. Personnel assignment matrix: Similar to option C, this is not a recognized term in the PMBOK® Guide. The standard term for this functional grid is the Responsibility Assignment Matrix (RAM).
