Yes. I can recommend this approach, but do not think it will come cheap or out of the box. Costs will only be slightly smaller than with standard programming (but much lower than n-versioning anyway). I suggest you call Mentor and ask them to come and show you BridgePoint. They have code generators that will give you C, C++, Java and Ada. If they claim not to have Java or Ada, ask them again. However having out of the box code generator is not what you want, trust me. It will give you a good starting point to learn how to make platform independent models. If you already know UML you will have to un-learn a lot a re-learn what object oriented analysis is really about. For all full MDA projects the old saying "Uncertainty is not an option" is not to be taken mildly. What's not in your model will not be in your generated code. After one or two years of (re)learning to model you will discover that you need a team maintaining the model compilers just as large as your modelling team. My experience is that by that time you will have a problem in convincing your management that this is true, after all you bought a model compiler so that you would have auto-generated code. Another thing you will learn is that it's not the same people that should do the modelling as you may be used to. The modelling really should be done by the domain experts. So if your model is targeted at flight control it should be done by those who really know what flight control is about, not by your software staff. Other models you do may be targeted at communication and should therefore be done by experts in communication. Your software staff should possibly not be doing modelling at all. (See above) I also suggest you hire a professional to get you started. The man my company has used is Leon Starr, but i'm sure there are alternatives. He is however a real pro at this. The only drawback I have found using xtUML is it's weak support for mathematical stuff. Implementing some mathematical algorithms will be a real problem and may perhaps be better to do directly in the target language and bridge into your models. If someone points you towards iLogix I would like to warn you a bit. Their tool does not support true platform independent modelling. You have to write action code in the target language, which in the end takes away the possibilities of simulating your code without first generating and it will allow your modellers to do stuff that should not be in your analysis models. And since your models then contains target specific stuff you will not have the possibility to change target language. KennedyCarter also has a product of which I have no experience. /Leif
