Extending analysis paradigms

It is suggested that natural language can be used as a guide to the development of conceptual models and as an aid for testing completeness. It is also suggested that conceptual models may be judged by how many of the following concepts are fully supported: entities, actions, relationships, events, concurrency, rules and constraints, communication, abstraction, and fuzziness. Neither requirements nor specification models should constrain an analyst who is describing problems or solutions. Underlying conceptual models must easily represent reality and must not be artificially constrained by some implementation paradigm. To this end, the authors argue for improving design techniques and programming languages so that these more powerful specifications can be easily implemented
