Practical Software Analysis vs. Design Modelling

Practical modelling in software analysis differs significantly from design. The IMHO main differences are highlighted here. Continue reading

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

Software for Managing Chaos

Workers in highly volatile contexts are best supported by software that implements generic communication or selfmanagement functionality. Like ACM systems do. Continue reading

A simple relational Model

Modelling foundations: What does a simple diagram ‘thing – relation – thing’ say, in terms of logic? 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

What kind of Computer Science matters?

Just came across Why Computer Science Matters? by Vugranam Sreedhar. He observes a decline in real computer scientists in favour of ‘commodity programmers’. Basically, I have to (sad but true) agree here, and would like to take a closer look … 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

Modelling with Classes: Square and Rectangle revisited

Classic problem in class-modelling: how to express that a square is a special kind of rectangle? In order to deepen understanding, let us scrutinize the situation a bit closer here, using logical/ structural foundations of modelling: Continue reading
