Does software modeling pay? – Empirical studies in UML (presentation)

The announcement of Michel Chaudron’s talk AT the Jeudi des Modèles conference series: Modeling effectively – insights from empirical studies raised some interesting discussions .

For those that could not attend the talk, Michel has upload the slides he used. You can see them here .

There is a lot of information on the slides (and unfortunately, without the context you’ll miss some things) but some quick conclusions of his experiments:

• Modelers ‘economize’ by focusing on complex and critical parts
• Modeling improves modularity
• Modeling improves understandability
• Modeling has also a somewhat positive influence in the correctness, testabilty and adequate coverage of the requirements.
• Using sequence diagrams reduce defects in the code

Reactions to these results?
