2. Decisions during software development (implementation)
many more alternatives …
association
class
Notice solution combinations between where to store the reference and data type
hash table
linked list
objects on both sides

3. Decisions during software development (design)
direct method invocation
MOM
Messaging middle-ware)
PCQ (Producer-Consumer-Queue)
intermediate asynchronous buffer

4. But, alternatives and the decision rationale not usually captured
So what? What’s the problem?
Evidence/justifications for
Why certain solutions were chosen?
What else were considered?
Why they were chosen over other alternatives?

5. Ok, what do we do then? represent and capture knowledge
→ to record alternatives & justify decisions
Once knowledge can be captured
organize knowledge
reuse knowledge

6. Representing knowledge A goal-oriented technique

7. How do we represent knowledge in this example
many more alternatives …

8. Alternatives and decision rationale
we can apply this technique to knowledge in other phases: req, architectural and detailed design

9. Apply to other phases

10. Organizing knowledge object-oriented organization
aggregation/
decomposition
generalization/specialization
classification/
instantiation

11. Organization example

12. Organization example (larger scale)
e-Commerce
pattern
OnlineBookstore
pattern
Composing patterns to form larger grain patterns …. to application level

13. Reusing knowledge
manual or model-driven

14. Conclusion A goal-oriented technique to explicitly
record alternatives
decision rationale
Object-oriented technique to organize by
generalization
aggregation
classification
For manual or model-driven reuse
Future work
formalization and integration with UML
tool support
case studies
