  Document which rules implement a feature to improve the traceability and extensibility of your application.

• Associating a feature with a work item

  Associate your assigned work items with the features that they implement to improve traceability in your application.

• Skimming features to the latest version

  Copy, or skim, features from previous versions of your application to ensure that the application that you ship includes the complete feature hierarchy.

• Deleting a feature

  Delete features when they are unused or no longer relevant.
