A Maintenance diagram is a type of Custom diagram, an extension to the UML model. It is a change management tool, used to record:
|·||Requests for change to the model structure or project process, as Change elements|
|·||Issues that impact the development and progress of the project, as Issue elements, and|
|·||Groups of tests that can be applied to many elements rather than specific elements, as Test Cases|
Each Change, Issue or Test Case element can link to other model elements in the project, to illustrate how they contribute to or are impacted by the item, and how they must be modified, removed, applied or extended to provide a solution. This includes identifying areas of work, represented by Task elements, to which resources can be allocated as either external (Actor) elements or internal properties (resource allocation).
