Defining Project Scope

Correct Answer: Work Breakdown Structure (WBS) decomposition level

The Work Breakdown Structure (WBS) decomposition level is the most crucial input for establishing a reliable time estimation baseline because: 1. It breaks down project deliverables into manageable work packages 2. It provides the necessary detail level to accurately estimate time and resources 3. It establishes clear boundaries for work efforts 4. It ensures all project scope elements are captured and measurable Why other options are less suitable: Project sponsor approval documentation, while important for project authorization, doesn't provide the detailed framework needed for time estimation. Historical data and benchmarking metrics are valuable references but they're secondary inputs that supplement the primary scope definition. Organizational process assets and environmental factors, though relevant, are contextual elements that influence but don't define the core scope components needed for scheduling. The WBS serves as the foundation for schedule development, resource allocation, and time estimation, making it the most crucial input for establishing a reliable scheduling baseline.

Correct Answer: Collect stakeholder requirements and expectations for deliverables

In PMI scheduling processes, collecting stakeholder requirements and expectations for deliverables is the first essential step in developing project scope. Here's why: The correct answer reflects the PMI principle that project scope must be based on stakeholder needs and expectations. This forms the foundation for all subsequent scheduling activities. Why other options are incorrect: Creating a WBS comes after requirements gathering, as you need to know what to break down first. Documenting assumptions and constraints follows the initial requirements gathering phase, as these are identified during stakeholder discussions and analysis. Establishing the baseline schedule is one of the final steps in schedule development, occurring after scope definition, WBS creation, and activity sequencing.

Correct Answer: Progressive elaboration through iterative stakeholder feedback

Progressive elaboration through iterative stakeholder feedback is the most effective approach for identifying project deliverables in an agile environment for several key reasons: 1. Aligns with Agile Principles - It emphasizes continuous adaptation and refinement based on stakeholder input 2. Enables Flexibility - Allows for scope adjustment as new information emerges 3. Promotes Collaboration - Facilitates regular interaction between team and stakeholders 4. Reduces Risk - Early and frequent feedback helps identify issues early The other options are incorrect because: - Comprehensive documentation at initiation contradicts agile's adaptive nature - Fixed baseline establishment is too rigid for agile projects - Sequential decomposition based on waterfall methods opposes agile's iterative approach The correct approach embraces agile's core values of adaptation, collaboration, and continuous improvement through regular stakeholder engagement and progressive refinement of deliverables.
