Guys,

I read a question about "Business need" somewhere in some mock test. I can't remember the wording of question but it was pretty simple, I selected the answer "Business case", but it was wrong answer. The correct answer was "Product scope Desription".

its at PMBOK  page 75. The problem is I see Business need in 3 places. Can somebody help me clearing this doubt:

Develop Project Charter: Inputs

.1 Project Statement of work

The statement of work (SOW) is a narrative description of products or services to be delivered by

the project. For internal projects, the project initiator or sponsor provides the statement of work based

on business needs, product, or service requirements. For external projects, the statement of work can

be received from the customer as part of a bid document, for example, request for proposal, request

for information, request for bid, or as part of a contract. The SOW references:

• Business need. An organization’s business need may be based on a market demand, technological

advance, legal requirement, or government regulation.

• Product scope description. This documents the characteristics of the product that the project

will be undertaken to create. The description should also document the relationship between the

products or services being created and the business need that the project will address.

• Strategic plan. The strategic plan documents the organization’s strategic goals. Therefore, all

projects should be aligned with the strategic plan.

.2 Business Case

The business case or similar document provides the necessary information from a business

standpoint to determine whether or not the project is worth the required investment. Typically the

business need and the cost-benefit analysis are contained in the business case to justify the project.
