Analyze Functional Requirements In Business Analysis

August 5, 2009
Functional requirements are analyzed to describe the desired behavior of a solution.
Functional requirements describe the behavior that the solution will manage. They describe capabilities the system will be able to perform in terms of behaviors or operations ¬タモ a specific system action or response.
Behavior also includes:
An effect that a solution must have within the problem domain in order to bring about a desired result,
How a person or system will interact with the proposed solution.
A standard that must be complied with
The functional requirements are well-written when they do not unnecessarily constrain the solution design. Functional requirements can be organized and presented in various ways. A selection of generally accepted techniques for analyzing and expressing functional requirements can be found in the appendix to this knowledge area.
The following are guiding principles in analyzing functional requirements:
Textual Documentation
Matrix Documentation
From the perspective of various stakeholders, a complete requirement must meet the following criteria:
Business Users: The requirement must capture the business objective and, if implemented, will fulfill a business need. Requirements must provide value to the users.
Project Team: The requirement must be stated completely enough to allow for construction and implementation of the solution.
Quality Assurance: The requirements must be stated clearly enough and completely enough that the QA group can test whether they are met by the solution.
