Production of methods
Representation
- capture the conceptual structure of IS method
- abstraction principles used in method management are generalization/specialization and aggregation/decomposition.
- An example of specialization is adding a new concept “time” to the general ER diagramming technique, and, hence, specializing it to be ERT diagramming technique.
- Aggregation and decomposition principles are used when we collect the method fragments together into a method specification.
- notations of method fragments have been basically textual, although graphics is also used
- version management of method fragments
- important issue because methods evolve and change due to accumulated knowledge of projects
