Linking Work Items (CMMI)

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

You create relationships between Requirements, Tasks, Test Cases, and other work items through the Implementation, Links, All Links and Test Cases tabs on the forms for those work items. This topic describes the controls and data fields that are associated with creating links and hyperlinks.

For more information about how to use links, see Projenizi Etkin Şekilde İzlemek için Bağlantı Türlerini Seçme. For more information about how to create links, see Traceability çalışma öğeleri ve diğer kaynakları arasındaki ilişkileri oluşturarak destekleme.

The process template for MSF for Capability Maturity Model Integration (CMMI) Process Improvement v5.0 provides a few reports that require you to create links between specific work items. Specifically, the Requirements Overview and Requirements Progress reports require you to create links between Requirements and Tasks and between Requirements and Test Cases.

In this topic

• Link Toolbar Buttons

• Link Controls and Restrictions

• Default Link List Data Fields

• Additional Link Related Fields that Support Query and Reporting

Link Toolbar Buttons

Each tab provides a toolbar, which contains the buttons that the following illustration summarizes:

The following buttons become available only after you perform a specific action:

• The button to create a work item that is linked to the open work item () becomes available only after you save the open work item.

• The buttons to open the list of work items in a query () and in a Microsoft Office client () become available only when at least one work item is listed in the links control tab.

• The buttons to open a work item (), edit a link (), and delete a link () become available only after you click one or more work items listed in the links control tab.

Link Controls and Restrictions

All tabs that support creating links between work items are implemented by using the LinksControl element on the work item form. This element controls filtering and restricting the types of work items to which you can link, the types of links that you can create, and whether you can link to work items in another team project. For more information about how to restrict links, see LinksControlOptions Öğeleri.

The following table summarizes the restrictions for all types of work items.

Work item type	Name of links control tab	Link restrictions
Requirement Task	Implementation	Allows only Parent and Child links. Excludes links to work items in other team projects.
Requirement	Test Cases	Allows only Tested By links. Allows links only to Test Cases. Excludes links to work items in other team projects.
Requirement Task Test Case Bug	All Links	No restrictions.
Test Case	Tested Requirements	Allows only Tests links. Allows links to any work item type. Excludes links to work items in other team projects.
Change Request Issue Review Shared Steps	Links	No restrictions.
Bug	Test Cases	Allows only Tested By links. Allows links only to Test Cases. Excludes links to work items in other team projects.
