- mainly mechanize pen and paper -mentality of methods
- methods are fixed part of a tool ~ no modifications allowed
- only the data support ~ model drawing and consistency checking tools
- group-work features are modest
Weak support for user-native methods
- neglect organization's own standards and methods
- no support for new areas or techniques of ISD, (business re-engineering, inter-organizational ISs, object-oriented approach)
- do not allow incremental adaptation
Shortcomings of building own CASE
