Quick Answer
The answer is the Responsibility Assignment Matrix (RAM). This document is the correct choice because it explicitly maps project work packages or activities to team members, typically using a RACI format to define who is Responsible, Accountable, Consulted, and Informed. By providing a clear, documented assignment of duties, the RAM directly resolves conflicts arising from unclear roles and responsibilities, eliminating ambiguity about who does what. On the CompTIA Project+ PK0-005 exam, this question tests your understanding of key project documents used in the execution phase; a common trap is confusing the RAM with the project charter or a communication plan, which do not detail individual task ownership. To remember this, think of the RAM as the project’s “role map”—if you need to clarify roles, you need the matrix that assigns them.
This PK0-005 practice question tests your understanding of project management concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project team is experiencing conflicts due to unclear roles and responsibilities. Which document should the project manager refer to in order to clarify team members' roles?
Responsibility assignment matrix (RAM)
RAM explicitly shows roles and responsibilities.
Project charter
Why wrong: Charter authorizes the project but does not detail team roles.
Work breakdown structure (WBS)
Why wrong: WBS decomposes work, not roles.
Communications management plan
Why wrong: Focuses on communication, not role definition.

Correct answer & explanation
Responsibility assignment matrix (RAM)
The Responsibility Assignment Matrix (RAM) is the correct document because it explicitly maps project work packages or activities to team members, showing who is responsible, accountable, consulted, and informed (RACI). This directly resolves conflicts arising from unclear roles and responsibilities by providing a clear, documented assignment of duties.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
CompTIA often tests the distinction between the RAM and the project charter, as candidates may mistakenly think the charter defines all roles, when in fact it only names the project manager and high-level stakeholders.
Detailed technical explanation
The RAM is often implemented as a RACI matrix, which uses four categories: Responsible (the doer), Accountable (the approver), Consulted (subject matter experts), and Informed (stakeholders kept in the loop). In complex projects, a single task may have multiple Responsible parties but only one Accountable person, preventing ambiguity and finger-pointing when deliverables are missed.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
