Ideas on Enterprise Information Systems Development

This blog is devoted to ideas on Enterprise Information Systems (EIS) development. It focuses on Lean Thinking, Agile Methods, and Free/Open Source Software, as means of improving EIS development and evolution, under a more practical than academical view. You may find here a lot of "thinking aloud" material, sometimes without scientific treatment... don't worry, this is a blog!
Every post is marked with at least one of Product or Process labels, meaning that they are related to execution techniques (programming and testing) or management techniques (planning and monitoring), respectively.

Proof of Concept for the BLDD Tool - Part V

Last week I bumped into what I think is one of the firsts academic papers on BDD to be published in a scientific journal. We have published three technical reports in, but they weren't peer reviewed: Filling the Gap between Business Process Modeling and Behavior Driven Development, Mapping Business Process Modeling constructs to Behavior Driven Development Ubiquitous Language and  A Tool Stack for BDD in Python.

This paper is on applying Model Driven Development (MDD) techniques to BDD, following the principles presented in the Agile for MDD white paper. The authors use Foundational UML (fUML), which defines a basic virtual machine for UML, to create bUML, a tool to support BDD activities that automatically updates the project status.

Our approach holds some differences in relation to theirs:
1) Although the examples in the paper are too "recursive" (given-when-then is used to describe the creation of stories and scenarios) to check details of their proposal, it is obvious that they follow MDD, in fact, at some point they say "The generated code intends to be complete, with no placeholders for the developer to fill out." We do the opposite: we leave placeholders to be filled out.
However, I still need to see some more practical example to affirm this.
2) Our proposed tool is meant to run step by step, I saw no reference to this kind of feature in bUML's description.
3) They use OCL as the basis for textual modeling, we propose to use a more natural should language. We envision the use of (some) should-dsl to insert and describe conditions (logical, acceptance) for the tests. OCL is a standard, however, should-dsl is closer to the user's language.

I need some more time to check bUML - I couldn't find the software or real world examples.  What I can say now is that they follow MDD, we follow Agile, so our proposals differ in the way we intend to implement and use the tools.
