PMP Practice Question: Business Environment: strategy and project benefits
A project manager is developing the business case for a new product. Which of the following is the primary purpose of the business case?
⚠ Common exam trap
It's easy for candidates to confuse the business case with the project charter or benefits management plan, as candidates often mistakenly think the business case authorizes the project or details benefit measurement, when in fact it only provides the justification for the project to be considered.

Correct answer & explanation
✓
To provide justification for undertaking the project based on expected business value.
The business case is a foundational document created during the pre-project phase to justify the investment. Its primary purpose is to provide the economic and strategic justification for undertaking the project, based on the expected business value, such as ROI, payback period, or alignment with organizational goals. This aligns with the PMBOK Guide's definition of the business case as a tool to determine if the project is worth the required investment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To define how the project will be executed, monitored, and controlled.
Why it's wrong here
This statement is incorrect because defining how a project will be executed, monitored, and controlled is the explicit purpose of the Project Management Plan. The Project Management Plan is a comprehensive document that integrates all subsidiary plans and baselines, detailing the strategies and processes for managing the project work, scope, schedule, cost, quality, resources, communications, risk, procurement, and stakeholder engagement throughout the project lifecycle. The business case, conversely, is developed much earlier to justify the project's existence, not to plan its detailed execution.
- ✓
To provide justification for undertaking the project based on expected business value.
Why this is correct
This statement is correct. The business case is a critical pre-project document that provides the necessary information to determine if a proposed project is strategically aligned and financially viable. It articulates the problem or opportunity, analyzes various options, and presents a detailed justification for undertaking the project based on its expected business value, return on investment, and contribution to organizational objectives. This document is fundamental for decision-makers to authorize the project.
- ✗
To outline how the project's benefits will be delivered and measured.
Why it's wrong here
This statement is incorrect because outlining how a project's benefits will be delivered and measured is the primary function of the Benefits Management Plan. While the business case identifies the potential benefits that justify the project, the Benefits Management Plan specifically details the processes for creating, maximizing, and sustaining those benefits. This plan defines the benefit owner, metrics, assumptions, and the timeline for benefit realization, often extending beyond the project's completion.
- ✗
To authorize the project manager to use organizational resources.
Why it's wrong here
This statement is incorrect because authorizing the project manager to use organizational resources is the specific purpose of the Project Charter. The Project Charter is a formal document issued by the project initiator or sponsor that formally authorizes the existence of a project and provides the project manager with the authority to apply organizational resources to project activities. The business case, while providing justification, does not grant any formal authority to the project manager.
