Connecting Technical and Organizational Components to Requirements
Reminder of principle
The technical and organizational components to which the requirements relate can be specified.
For example, the "Purchasing Management" application must respect requirements related to setting up a product catalog and a centralized supplier database.
These links can be created graphically in the objective and requirement diagram.
Adding an application in the objective and requirement diagram
To connect an application to a requirement in an objective and requirement diagram, we must first show the applications in the diagram since they are not displayed by default.
To view applications in a project objective and requirement diagram:
1. Click the
Views and Details
button in the diagram toolbar.
2. Select the Applications, IT Services, Databases check box.
3. Click OK.
The corresponding buttons appear in the insert toolbar.
To insert an application in the objective and requirement diagram:
1. In the objects toolbar, click the Application button.
2. Click on the diagram.
The add application dialog box appears.
3. Click the arrow at the right of the Name box and select Propose in the drop-down list.
The list of applications accessible from the current library appears.
4. Select the required application.
5. Click OK.
The application appears in the diagram.
Connecting an application to a requirement
Connecting an application to a requirement can have two non-exclusive meanings:
• Either the application contributes to satisfaction of a requirement,
• Or the application is constrained by the requirement.
To graphically specify that an application contributes to satisfaction of a requirement :
1. Click the reel button
in the insert toolbar.
2. Click the applicationand, holding the mouse button down, draw a link to the requirement.
3. Release the button.
The directional link appears as a dotted line from the application to the requirement.
To graphically specify that an application is constrained by satisfaction of a requirement:
1. Click the reel button
in the insert toolbar.
2. Click the requirement and, holding the mouse button down, draw a link to the application.
