Reflections on Abstractions: Correctness and Completeness

An earlier post on quality properties of models is compared to basic concepts of mathematical logic, in strive for rigour. What does a formal system of mathematical logic has in common with a modelling situation as in requirements analysis? It depends … Continue reading

Models: Correct, Complete, Consistent, Unambiguous

How do you judge how ‘good’ or ‘bad’ a model is? I mean models like we use them in software requirements specification or business analysis. On this, one can find criteria in literature like BABOK, Wikipedia, IEEE, research papers, or textbooks. However, for some reason these criteria sets are quite different in each case. I’ve tried to get the things a little straighter, starting with the ‘big four’ quality characteristics of software requirements specifications … Continue reading

Rich World – Poor Models

How can an inherently complex reality be mapped to formal models? Comprising the context and choosing the right abstractions can help. Continue reading
