The A&D Forum
Until recently this was the UML forum. This is still an appropriate place for your questions about the UML but we decided to broaden the focus a bit to make this forum applicable for a range of process and design issues that are important to development strategy.
Feel free to discuss here any questions you have involving:
* Choosing an application architecture
* Understanding various architectures, including SOA
* Modeling (UML, DSL, etc.) and MDA
* Agile methodology, Extreme programming, etc.
* Requirements management
* Business process management
