Enterprise, Business, and Technical Architects (ITANA) Constituent Group

We are thinking about it, in fact I had a meeting this morning where it was discussed.  We’ve done a few on-off projects in the past that provide enterprise data to services managed outside of central IT.  We have a couple of applications that query data through our LDAP proxy service and one that we wrote a specific web services interface for but we want to look at the possibility of a more standard and scalable approach.   Besides determining a suitable technical solution, we know we will need to work out a request and approval process that includes the data owners and some sort of application review to verify accurate use of the data and that appropriate access controls are being used in the consuming application. We also want to make sure application owners are informed about existing record policies.

We are in the early stages of thinking through...

This has turned into  an epic reply so  I’ll provide an abstract:

I have done some basic mapping of our systems portfolio, there isn’t much in the way of architectural tools to support this kind of activity.   There is a cross over here with ITIL based service management approaches.  Much of the approaches I’ve seen take a “bottom up” approach of map the detail and then summarise into an overview, however this is resource intensive.   Tools to help take a “top down” overview from 50,000 feet would be useful, a good starting point would be classifying service provision into major service areas.
