Universal versus application-specific methods
Have methods solved the problems in ISD?
- Not as expected/hoped = methods are surprisingly little used
- Organizations tend to adapt/build own methods instead of using 3rd party methods
Can ISD be supported by a single method?
- Contingency approach = No!
- Experiences from standardization efforts = No big success!
- Tried already in 70’s with IDEF (DoD), 80’s with SSADM (UK) and Merise (France), and in 90’s with Euromethod
- Now tried again with UML
Why not?
- Software development tend to be situation-specific
- technology evolves, systems evolves, huge differences in systems, organizations, cultures, tools in use etc.
