To add a new feature to an existing object oriented design, analyze current OOD artifacts and incoming OOA drafts to identify integration points. This ensures reuse of established classes and packages while introducing minimal, coherent architectural changes.

The use-case-driven workflow for extending object oriented design progresses through six steps: Architecture, Use Case Realization, GRASP, Patterns, DCD, and cross-cutting concerns. Each step maintains traceability between existing design artifacts and the new feature draft.

Yes, you need existing OOA drafts and OOD artifacts to integrate a new feature draft. The process requires analyzing both current design outputs and new analysis inputs to safely extend the architecture and maintain domain object consistency.

Applying GRASP when reusing current architecture involves assigning responsibilities to existing or new domain objects during the realization step. This guides the integration by ensuring the new feature draft adheres to established design patterns and principles.

The best way to maintain traceability when adding a new OOD feature draft is following the structured 6-step OOD workflow. This provides structured outputs for design drafts and maps new realization decisions back to existing architecture and OOA inputs.
