You can manage your system's Requirements by identifying, describing them, and then organizing them in your project. Requirements management ensures that text-based requirements verify and meet the needs of stakeholders. The following figure illustrates the abilities of modeling Requirements in the modeling tool.
Capture requirements in the Requirement Diagram and Requirements Table by creating or importing them in the modeling tool. The Requirement Diagram provides modeling constructs to represent text-based requirements and relates them to other modeling elements. A Requirement Table is used to type requirements into a spreadsheet-like table.
Once requirements are gathered you can support them as follows:
The relationships among requirements and design elements (such as SysML Blocks, Test Cases, Use Cases, etc.) create a great value in your model. You can create relationships such as derive, refine, satisfy, or verify directly in the Requirement Diagram or the Requirement Matrices.
Requirements can be visualized in multiple predefined views:
The requirements analysis encompasses those tasks that determine the needs or conditions a new or altered product or project must meet. It considers the possibly conflicting requirements of the various stakeholders by analyzing, documenting, validating, and managing software or system requirements.
Work on requirements in teams by using the MagicDraw Teamwork Server repository, which enables effective team collaboration, change and configuration management, allows for restricting access to the project, and multisite support. Use Suspect Links to track changes in requirements that are linked to design elements by satisfy, derive, refine or verify relationships, as well as allow tracking unlinked requirements and deprecated requirements.
With the system parameter calculated, you can verify the system requirement and give the verdict on whether it is satisfied or not. The modeling tool enables you to perform this verification automatically.
