• Consistency checking
• Specific Problems for aspects

4
Features and Aspects

• Using feature diagrams to identify aspects
• for subsequent phases
• Feature aspects crosscutting other features in
  the feature diagram

• Variations of features at one level
• Hierarchy of level

Aspect for capturing Variability
