The Killer Application of Software Modelling

From my experience as a business analyst (BA) I would say: checking or transforming models is interesting and important, but the real killer application of a model in software development is (simply) talking about it. Continue reading

Unambiguous Requirements Models

We’ll see that the concept of ambiguity of (requirements in software engineering) models comprises structural as well as material aspects, on all model levels (top to bottom). Continue reading

Modeling for Understanding and/xor/etc Execution

Executable models have a great potential for achieving real separation of concerns. However, some practical modeling aspects on the business side deserve closer attention. Continue reading

Splitting the Requirements Atom

Atomicity is considered an important property of requirements. However, if we take a deeper look, we see the concept of atomicity lacks in rigour. Is e.g. the atomicity concept of Logic suitable here? Continue reading

Modeling & Abstraction at the very heart of Business Requirements Analysis

From industrial practice we know a BA definitely adds a lot of value to an IT project. So, now we try to conceptualise this in contrast to the Biz Engineer’s and IT Architect’s role. As we’ll see, a BA’s special benefit is mainly based on abstraction (and thus modeling). Continue reading

Software Requirements Analysis: From the Art of Tidying Up to the Art of Abstraction

Requirements analysis is more than just tidying up, it’s about understanding the complexity of structures. An explanation inspired by the art of Ursus Wehrli: Continue reading

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

Henry Ford and Business Analysts

“If I had asked people what they wanted, they would have said faster horses.” – Henry Ford –
Isn’t this a nice litte example to show what Business Analysts are good for? Continue reading

Complexity Awareness is Cost Awareness

If “engineering is producing an artifact to cost”, then how can modelling contribute to it? Continue reading
