EA and IT Service Management
I completed my USA trip with a visit to the EA team at Miami
University. For the uninitiated (as I
was), don't confuse this with the city in Florida: Miami University is in Oxford, Ohio, and takes its name
from that of the local Native American tribe.
The EA team at Miami is newer than the other teams I visited on this trip. Still, they have managed to achieve quite a
lot in the few years of their existence.
Their CIO has tasked them with mapping the current state of the five domains
(Business, Information, Applications, Infrastructure and Security) and they
have made good progress with this.
Their Enterprise Architect chose to use simple tools for this task. By using Google sheets to collect data, they
could crowd source much of the information, getting input from the staff within each
org unit who know the details of which applications are used to deliver which
capabilities. This had a secondary
effect of publicising the work of the EA team within the University and giving people some sense of
involvement.
They have also written some PHP and AngularJS scripts to give simple graphical views
of this information. The following
example shows the three levels of business capabilities for Learning, with each
level three capability mapped to the central IT applications that support it.
I was particularly interested by the way the team are
integrating EA with the ITIL service management initiative. They have entered
capabilities into their Configuration Management Database (CMDB) so that they
can map ITIL services to business capabilities.
The applications are already in the CMDB, of course, so the mapping of
applications to capabilities can also be represented in the CMDB. The CMDB also has entries for each interface between
applications, with links to more information on the EA web site.
I’d like to know more about how to relate ITIL services to
EA business capabilities. It would seem
that an ITIL service should represent a business capability, which would imply
that the ITIL service catalogue should ideally be a subset of the business
capabilities captured by EA. At
Edinburgh, our service teams are finding it challenging to decide which
services should be represented at which level of our ITIL catalogue. Perhaps EA techniques might be able to help.

Here is a link to our modeling spreadsheet:

Which can show you how we attempted to map capability to service.
The next steps are to map the capabilities to services and service to technical applications in the CMDB with the goal to visualize the relationships between capability, service, application and tickets.
