[...] Henrik Hammer Jordt præsenterede ISO/IEC 42010 (2007) som definitionen for enterprisearkitektur. Standarden er forældet. Jordt kom sidenhen ind på at der essentielt så findes der ikke en god definition på, hvad [...]

I am on a project where we have started to use Vensim and iThink as a tool for simulating the effectives of a capability and how to determine which capabilities to invest in. I will publish these in roughly six months as soon as we get the kinks out. I am so happy to here that there are others interested in using Systems Dynamics in modeling aspects of enterprise architecture. Keep up the good work.

John, Congratulation for this initiative. Whenever I can find some time I'll post comments on some of the diagrams (on their pages). Now some general questions: 1. Are these diagrams intended to be used only by their qualitative capacity? 2. If not, how can we see the equations? 3. Are the Vensim models available for download? 4. Have you envisaged collaborative development of these models? And one idea related to the last question. Recently I published some CLDs on relations between Beliefs and Capabilities on my blog. Then I thought, I shouldn't limit this with my assumptions, beliefs and experience, so now I plan to publish it as Insight maker model. The reason I chose this tool (by the way the models are initially developed with Vensim as well) is because I don't know of any other online free collaborative environment for SD models. With the models that you published here, the potential is even bigger. The ones I mentioned are just CLDs and not SFDs so they will not benefit from the powerful simulation capabilities of Insight Maker, while yours can. Well, just a suggestion...

Yes, the models are overly simplistic and very loosely coupled. We would be very interested in suggestions for improvements.

Nasty bit of spaghetti you've got going on there. Feedback loops are not at all clear.

Hey John Really nice to meet again and talk this week :-). I can suggest "The real value of IT" by Richard Hunter, fellow at Gartner, and George Westerman, reseacher at MIT. They draw on more than 10 years of research and their conclusions are wery similar to the way I understand and practice EA. I will be delighted to present the content myself on such an occasion. Have a look yourself.
