UML Process Diagrams: Learn Enterprise UML Technical Systems

Management is all about balance, communication, collaboration, adjustment, and consensus as requirements are discovered, captured, executed, tested, and delivered. To prevent one class of requirements from over-riding another, constant communication and collaboration among members of the project, development, test, and delivery teams is crucial. For example, in software development for internal applications, the business has such strong user requirements needs that may be ignored, or believe while creating use cases, the user requirements are being taken care of when these are not expressed, captured , defined, and documented. This can lead to missed requirements, expectations or project failure.

The purpose of Requirements management is to ensure project requirements meet business needs and expectations as inconsistencies are identified among those requirements supported by project plans ensuring work products delivery. Further, requirements management practices must include change management and traceability.

What is a Requirement? A requirement is a measurable action or set of actions a system must do (behaviors and functions). It may also be a measurable quality or property a system must have (attributes and persistence). Requirements must capture what is needed to satisfy client business processing needs and expectations in delivered systems. Requirements are categorized as three types: Functional, Non-functional (Performance), and Constraints. Issues are used to define risks involved in meeting requirements. Work Inventory is a collection of all completed and non-completed work and issues.
