EA and IT Service Management


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.

Miami is also the the name of a two rivers (Great Miami and Little Miami) that flow into the Ohio River on either side of Cincinnati.

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.

Presentation: Putting IT all together

This is a presentation I gave to an audience of University staff: 

In this seminar, I invite you to consider what the University’s online services would be like, if we worked together to design them from the perspective of the student or member of staff who will use them, instead of designing them around the organisational units that provide them. I’ll start with how the services might appear to that student or member of staff, then work back from there to show what this implies for how we work, how we manage our data, and how we integrate our IT systems. It might even lead to changes in our organisational structure.

Our online services make a vital and valued contribution to the work of our students and staff. I argue that with better integration, more consistent user interfaces, and shared data, this contribution could be significantly enhanced.

This practice is called “Enterprise Architecture”. I’ll describe how it consults multiple organisational units and defines a framework …

Service Excellence, Digital Transformation and Enterprise Architecture

Our University Secretary has sponsored a major review of the University’s administrative processes, coining the banner “Service Excellence”.  The aim is to look at the services we provide to staff and students with a fresh eye, making them more effective, more efficient, and focussed on the user rather than administrative convenience.

Our CIO is sponsoring a similar programme called “Digital Transformation”. This will replace old paper-based processes, starting with the question of what would processes look like if we designed them afresh for the modern connected world.  The aim is to make processes that are more focussed on the user and hence more effective and efficient.

Both of these ambitious programmes will need an effective enterprise architecture, if they are to succeed.  Digital Transformation is intrinsically about using opportunities provided by new technology to improve services and, as such, it requires effective technology services to make data available when needed, to pro…

Not so simple...

A common approach to explaining the benefits of Enterprise Architecture is to draw two diagrams: one that shows a complicated mess of interconnections, and one that shows a nicely layered set of blocks. Something like this one, which came from some consultants:


I've never felt entirely happy with this approach.  Yes, we do want to remove as much of the needless complexity and ad-hoc design that litters the existing architecture.  Yes, we do want to simplify the architecture and make it more consistent and intelligible.  But the simplicity of the block diagram shown here is unobtainable in the vast majority of real enterprises.  We have a mixture of in-house development and different third-party systems, some hosted in-house, some on cloud infrastructure and some accessed as software-as-a-service.  For all the talk of standards, vendors use different authentication systems, different integration systems, and different user interfaces.

So the simple block diagram is, basically, a l…
