Conclusion

Initial goals

Cost : Optimize the resources staffing.

– Make preliminary effort on design – Postponed coding effort

Quality : Minimizing defects and the complexity

– Behavior design– Share a common model

Features : Maintain a flexible software architecture

– "high level" model - functional point of view – Documentation up to date

Time : Keep good productivity on time

– Do not start from scratch for coding

Steps

1. Work together on design

– abstracting technical details

– Generate functional design document

2. One shot code generation

– For boring EJB classes

– Skeleton and JavaDoc

3. Near MDA

– Add PSM

– Code round trip

Feedbacks

Impediments

– Multi-users with Objecteering

– Too many steps (PIM – PSM – Code)

– Transformer to complex

– Java generator not fully customizable

Benefits

– Very fast project start up

– Hide technologies complexity

– Documentation always up to-date

Feedbacks

Impediments

– EA is evil– EA is not an UML 2 tools– XMI export change every minor version

– Still a bit long

Benefits

– Acceleo transformer accessible for Java developer– With real development tools– 15 000 lines J code = 3 000 lines Acceleo script

– No more PSM

– Much less licenses

– Good EA documentation generator

Conclusion

Conclusion

We believe in MDD approach

– Increases productivity and quality

– Good development framework We need a complete Eclipse UML modeler

MDD can be use in agile development

– Change some manager wrong vision :
