Project Business Documents: Business Case and Benefits Management Plan
PMBOK v8 Definition
Project business documents include the business case and the benefits management plan. These documents are developed prior to project initiation, referenced after project completion, and used throughout the project life cycle. They are considered business documents rather than project documents or components of the project management plan. As appropriate, these business documents may be inputs to some processes involved in managing the project, such as developing the project charter.
The business case is a documented economic feasibility study used to establish validity of the benefits to be delivered by a portfolio component, program, or project. The benefits management plan describes how and when the benefits of the project will be delivered and measured.
Why It Matters for the Exam
The PMI exam frequently tests your ability to distinguish business documents from project documents and project management plan components. Questions often appear in the Initiating Process Group and focus on which documents are created before the project charter, who is accountable for them, and how they are used throughout the project life cycle. Expect situational questions where you must identify the correct document for a given scenario.
Key Points to Remember (for the exam)
-
Definition: Business documents = business case + benefits management plan. They originate outside the project but serve as inputs to project processes.
-
Timing: Both documents are developed prior to project initiation and are referenced after project completion.
-
Accountability: The project sponsor is generally accountable for the development and maintenance of the project’s business case document.
-
Go/No-Go Decision: The business case may be used before project initiation and may result in a go/no-go decision for the project.
-
Success Measurement: The business case helps measure project success at the end of the project against the project objectives.
-
Common Confusion: Business documents are NOT part of the project management plan. They are separate, ongoing references that exist outside the project but inform it.
-
Input to Processes: These business documents may be inputs to processes such as developing the project charter.
Typical PMI Exam Example
Scenario: A project manager is asked to review a document that was created before the project was approved. This document contains the economic feasibility study and the justification for initiating the project. It will be used to measure success at project completion.
Question: Which document is being described?
Answer: The business case (a project business document).
PMI Exam Traps
-
Trap: Confusing the business case with the project charter. Reality: The business case is developed before the charter and justifies the project. The charter formally authorizes the project.
-
Trap: Treating business documents as part of the project management plan. Reality: Business documents are separate from the project management plan. They are created prior to the project and exist outside the plan.
-
Trap: Assigning accountability for the business case to the project manager. Reality: The project sponsor is accountable for the business case, not the project manager.
-
Trap: Thinking business documents are only used during initiation. Reality: They are used throughout the project life cycle and referenced after project completion.
