Project Management Project Scope and WBS — Questions and Answers

Question 1: A project manager discovers that a vendor has delivered a feature that was not in the approved scope but is potentially useful. What should the PM do?

Accept it since it adds value
Reject it and initiate a change request if the team wants it included (Correct answer)
Include it in the project scope baseline immediately
Escalate to the project sponsor for approval without a change request

Correct answer: Reject it and initiate a change request if the team wants it included

Unsolicited deliverables outside the approved scope should be rejected unless processed through formal change control.

Question 2: Which document formally authorizes the project and gives the project manager authority to apply resources?

Project Management Plan
Project Charter (Correct answer)
Scope Statement
Requirements Traceability Matrix

Correct answer: Project Charter

The project charter formally authorizes the project and grants the PM authority to use organizational resources.

Question 3: In a WBS, the work package is best described as:

The highest level of project deliverables
The lowest level of the WBS where cost and duration can be estimated (Correct answer)
A summary of all project phases
The list of all project milestones

Correct answer: The lowest level of the WBS where cost and duration can be estimated

Work packages are the lowest WBS level where schedule and cost can be realistically estimated and managed.

Question 4: A project's scope baseline consists of which three documents?

Project charter, scope statement, and WBS
Scope statement, WBS, and WBS dictionary (Correct answer)
Requirements document, WBS, and project schedule
Project plan, WBS, and stakeholder register

Correct answer: Scope statement, WBS, and WBS dictionary

The scope baseline is the approved version of the scope statement, WBS, and WBS dictionary.

Question 5: During project execution, a stakeholder requests a small addition that will take only two hours. The PM should:

Allow the team to complete it since it is minor
Submit a change request and await approval before proceeding (Correct answer)
Add it to the next sprint automatically
Document it in the lessons learned register

Correct answer: Submit a change request and await approval before proceeding

All scope changes, regardless of size, must go through integrated change control before work begins.

Question 6: What is the primary purpose of a Requirements Traceability Matrix (RTM)?

To assign resources to project activities
To link requirements to their origins and track them through the project lifecycle (Correct answer)
To create the project's WBS hierarchy
To document lessons learned from requirements gathering

Correct answer: To link requirements to their origins and track them through the project lifecycle

An RTM traces each requirement from its source through design, development, and testing to ensure full coverage.

Question 7: Which technique is commonly used during scope planning to gather requirements from a large, geographically dispersed stakeholder group?

Focus groups
Interviews
Surveys and questionnaires (Correct answer)
Benchmarking

Correct answer: Surveys and questionnaires

Surveys and questionnaires are efficient for collecting input from many stakeholders across different locations quickly.

Question 8: The 100% rule in WBS development states that:

100% of team members must approve the WBS
The WBS must capture 100% of the work, including project management work (Correct answer)
All work packages must be completed in 100 hours or less
100% of risks must be identified before the WBS is finalized

Correct answer: The WBS must capture 100% of the work, including project management work

The 100% rule requires that the WBS captures all deliverables and work, including project management activities, without overlap.

Question 9: Gold plating in project management refers to:

Using premium materials to exceed quality standards
Adding features beyond the agreed scope without a change request (Correct answer)
Charging clients a premium rate for specialized work
Applying best practices from high-performing industries

Correct answer: Adding features beyond the agreed scope without a change request

Gold plating is adding extra scope or features not requested by the client, which consumes resources without formal authorization.

Question 10: What differentiates a project scope statement from a product scope statement?

Product scope describes project deliverables; project scope describes the work to produce them (Correct answer)
Project scope includes budget; product scope does not
They are interchangeable terms in PMBOK
Product scope is created before the project scope statement

Correct answer: Product scope describes project deliverables; project scope describes the work to produce them

Product scope describes the features of the product or service, while project scope describes the work required to deliver it.

Question 11: During Validate Scope, a key deliverable is reviewed and accepted by the customer. This acceptance is documented in:

The project management plan
Accepted deliverables and change requests if rework is needed (Correct answer)
The WBS dictionary
The lessons learned register

Correct answer: Accepted deliverables and change requests if rework is needed

Accepted deliverables are the primary output of Validate Scope, along with change requests for items requiring rework.

Question 12: A project manager is working with SMEs to break down a high-level deliverable into smaller components. This technique is called:

Rolling wave planning
Decomposition (Correct answer)
Progressive elaboration
Bottom-up estimating

Correct answer: Decomposition

Decomposition is the technique of breaking down project deliverables and work into smaller, more manageable components.

Question 13: When scope definition is poor at project initiation, the most likely consequence is:

Increased team morale due to flexibility
Frequent scope creep and cost overruns (Correct answer)
Faster project completion
Better stakeholder satisfaction

Correct answer: Frequent scope creep and cost overruns

Poorly defined scope leads to uncontrolled changes, rework, and budget and schedule overruns throughout the project.

Question 14: Which output of the Collect Requirements process is used as a key input to Define Scope?

Project charter
Requirements documentation (Correct answer)
WBS dictionary
Stakeholder engagement plan

Correct answer: Requirements documentation

Requirements documentation, which captures stakeholder needs, is a primary input to the Define Scope process.

Question 15: A WBS dictionary primarily serves to:

Define the WBS numbering system
Provide detailed descriptions of each WBS component including acceptance criteria (Correct answer)
List all project stakeholders by role
Summarize the project budget by phase

Correct answer: Provide detailed descriptions of each WBS component including acceptance criteria

The WBS dictionary supports each WBS component with details such as description, acceptance criteria, responsible party, and resource requirements.

Question 16: Scope creep most commonly results from:

Poor risk management
Inadequate change control and stakeholder management (Correct answer)
Aggressive project scheduling
Insufficient team training

Correct answer: Inadequate change control and stakeholder management

Scope creep typically occurs when changes are allowed informally without going through change control and stakeholder agreements are unclear.

Question 17: On a large program, a project manager is uncertain about the details of work that is 6 months away. The best approach is:

Delay planning until the work is closer
Use rolling wave planning to plan near-term work in detail and far-term work at a high level (Correct answer)
Define all work packages now to avoid future rework
Create a separate project for the future work

Correct answer: Use rolling wave planning to plan near-term work in detail and far-term work at a high level

Rolling wave planning allows progressive elaboration, detailing near-term work while keeping far-term work at a higher level until more information is available.

Question 18: Which of the following is NOT typically included in a project scope statement?

Project deliverables
Project exclusions
Resource assignments by name (Correct answer)
Acceptance criteria

Correct answer: Resource assignments by name

Resource assignments by name belong in the resource management plan, not the scope statement.

Question 19: A customer requests a feature during execution that was explicitly listed as an exclusion in the scope statement. The PM should:

Add it immediately to maintain the relationship
Evaluate the request and process it through integrated change control (Correct answer)
Refuse the request without evaluation since it was excluded
Add it to the backlog for the next project phase

Correct answer: Evaluate the request and process it through integrated change control

Even excluded items can be added via formal change control; the PM should evaluate and process the request properly rather than refusing outright.

Question 20: The process of monitoring the status of the project and product scope and managing changes to the scope baseline is called:

Validate Scope
Control Scope (Correct answer)
Define Scope
Plan Scope Management

Correct answer: Control Scope

Control Scope is the process of monitoring scope status and managing changes to ensure the scope baseline is maintained.

Question 21: In agile projects, the product backlog most closely corresponds to which traditional PM artifact?

Project charter
Scope statement and requirements documentation (Correct answer)
Risk register
Stakeholder register

Correct answer: Scope statement and requirements documentation

The product backlog serves as the evolving list of features and requirements, functioning similarly to the scope statement and requirements documentation in predictive approaches.
