Short answer

A Project scope

Question

A project team is working on a document to precisely describe the success criteria that should be fulfilled by a product. Which of the following documents is the team preparing?

Project scope Correct Answer
Quality plan
Contract obligations
Work breakdown structure

Key Takeaways

Tests your ability to differentiate between project scope documentation and quality management plans, with the common trap being the misattribution of acceptance criteria to the quality plan.

The Project Scope Statement formally defines deliverables, boundaries, and acceptance criteria, serving as the baseline for project success. While candidates often confuse this with quality management documentation, community consensus and official guidance confirm that measurable success criteria belong in the scope statement.

Common mistake: Quality plan (Option B), because test-takers frequently assume that all success metrics and performance standards belong to quality documentation rather than recognizing acceptance criteria as a core scope component.

Expert Analysis

Why the Answer Is Correct

The Project Scope Statement explicitly outlines deliverables, boundaries, and acceptance criteria, which directly translate to the measurable success criteria for the product. According to standard project management frameworks and CompTIA’s alignment, defining what constitutes success is a foundational element of scoping. This ensures stakeholders and the project team share a unified understanding of project completion before execution begins.

Why the Other Options Are Wrong

A Quality Plan details the processes, standards, and testing methods used to achieve quality, but does not define the overarching business success criteria. Contract obligations outline legal terms and vendor requirements rather than internal project success metrics. A Work Breakdown Structure decomposes work into manageable tasks without specifying how success will be measured or accepted.

Community Comment Notes

Multiple users correctly point out that the Preliminary Scope Statement includes “Project Acceptance Criteria” as measurable outcomes of success [1]. Others emphasize that while quality plans track performance standards, they do not replace the scope statement’s role in defining final deliverable acceptance [3][4]. The debate highlights a common certification trap where quality-related terminology distracts from scope documentation fundamentals.

Exam Strategy

When encountering “success criteria” or “acceptance criteria” in exam questions, immediately associate them with the Project Scope Statement rather than quality or scheduling documents. Always look for keywords like “measurable outcomes,” “deliverables,” and “stakeholder agreement” to identify scope-related answers quickly.

Don't always rely on AI to be correct. Elements of a Preliminary Scope Statement • Project Scope Description: summarize the project’s intent and purpose. This section summarizes the project vision contents of the project charter. • Project Acceptance Criteria: list the success criteria of the project. Acceptance criteria are the measurable outcomes of success. This section expands on the success criteria element of the project charter. Where the success criteria may have listed three key measures, you might list six or more acceptance criteria on this scope statement.

From AI source... B. Quality plan A quality plan outlines the specific quality standards, metrics, and criteria that the product must meet to be considered successful. It details the expectations for product performance, functionality, reliability, and other quality attributes. By defining clear success criteria in the quality plan, the project team can ensure that the product meets stakeholder expectations and requirements.

From the Heldman K. Comptia Poject + Study Guide: • The purpose of the scope statement is to document the project objectives, the deliverables, and the work required to produce the deliverables. It is then used to direct the project team’s work during the Executing phase and as a basis for future project decisions. The scope statement is an agreement between the project and the project customer that states precisely what the work of the project will produce.

While the quality plan outlines the processes and standards that will be used to ensure the quality of the deliverables, it doesn't specifically define the success criteria for the entire project.

If you deliver on time and under budget, but the quality doesn’t meet your stakeholders’ expectations, the project is not a success.
