Unformatted text preview: How do you define the term Requirement? While this may seem like a very simple question, few Business Analysts ever take the time to ask or to understand “what is a requirement”. Per the BABOK v2.0 “A requirement is: 1. A condition or capability needed by a stakeholder to solve a problem or achieve an objective. 2. A condition or capability that must be met or possessed by a solution or solution component to satisfy a contract, standard, specification, or other formally imposed documents. 3. A documented representation of a condition or capability as in (1) or (2).” Many business analysts may assume that requirements describe condition or capabilities of a system. Or perhaps they avoid this trap and expand a requirement to encompass a condition or capability of a business process. However, the BABOK definition has been carefully crafted to ensure that what is stated does not arbitrarily constrain the true definition of a requirement based on poor assumptions about the problem domain.

But, ultimately, when eliciting requirements for a project, a requirement is not truly a requirement until it is documented. A requirement may be documented as a requirement statement such as “The system shall…”, “The process shall…”, “The Financial Analyst shall…”, or it can be documented through any number of representative techniques including models and diagrams. Requirements are typically classified into a number of categories for easier organization and maintenance. The BABOK classifies requirements into the following categories. 1. Business Requirements 2. Stakeholder Requirements 1 3. Solution Requirements 1. Functional Requirements 2. Non-Functional Requirements 4. Transition Requirements What are the characteristics of a good requirement?
