    4. Design Methods for Software : Goals

    5. Aspect Oriented Programming 1

    6. Aspect Oriented Programming 2

    7. Aspect Oriented Programming 3

    8. Requirements for an Aspect- Oriented SW Development Method

    9. Component-Based Development Components encapulate change (design decision / requirement)Components encapulate change (design decision / requirement)

    10. Design by Correctness Preserving Transformation

    11. Proposed Approach

    12. Proposed Approach 2

    13. How Can We Realize This? Ad.2. Weaving: any subset of aspects can be turned into an implementation => there should be default values for aspects Ad.3. Change dynamically: binding (weaving) of aspects should happen during run-timeAd.2.
