Preparing for a post-PC world?

Martin Hamilton has posted a thoughtful piece about the impact of the current IT trends away from the desktop PC and towards cloud computing.  I've been musing about how these changes might affect us as service providers.

The move towards staff and students using their own devices to access our services is well established.  We have a policy of providing services via the web whenever we can, giving people access to our services "anywhere, anytime".  The EASE system provides a single authentication point for common access and is integrated with Shibboleth as well.  There are still university systems that don't fit this model, perhaps because the vendor doesn't provide the option or because a university department has bought their own system without considering the wider picture, but we are moving in the right direction.

In some cases, the move towards outsourcing services can make this harder.  The big players all have their own authentication systems and want users to move into their world.  It isn't necessarily in the vendors' interest to have interoperable authentication, just as vendors of desktop systems before didn't necessarily want interoperable systems.  This is something we will have to keep pressing for.  Universities should keep working together on this - as we have with Shibboleth adoption.

Obviously a key aspect of the post-PC world is the expansion in the range of devices that people are using - phones, tablets, laptops, consoles, thin-clients, and so forth.  So far, we have the U@Ed service for smartphones and provide mail/diary services on phones too.  It seems to me that this is an area where we are likely to become more dependent on vendors, simply because of the support implications.  We simply can't test systems on all the different devices, with their different browsers and screen sizes, let alone different "apps". We can write systems to comply with standards, but standards are usually open to some interpretation.  If one of our systems doesn't work on a certain device, the best we can do is address problems as they arise, if we have the budget to do so.

So that's one side of the post-PC world: far fewer users using (or wanting) traditional PCs.  The other side is the use of cloud computing.  We already outsource some of our systems and we are looking at this option for others.  Some people tell us that all our services will end up being provided in the cloud.  I'm sure that many will, but it's interesting to compare this with the current situation where we procure a lot of applications to run locally.

Even though we are using more third-party systems than before (either from vendors or open-source projects), we are still asked to build local systems, or to substantially reconfigure third-party systems.  It seems that the market does not address all the needs of a complex university (or in some cases, not at an affordable price).  It will be interesting to see whether cloud-based commercial systems will address more of our needs, or whether the scale required will mean even more space for local niche applications.



Basically, when it comes to providing services, we are cloud providers, as far as our users are concerned.   They connect to our services via the web just as they do with commercial services such as Google or Microsoft.  In some cases, we know that we can provide these services cheaper than the commercial options.  So our decision will be whether to run our "cloud" services in-house, to outsource them (while still branding them as university services), or to stop providing them and let our staff and students use the commercial ones.  Factors affecting this will include data protection considerations, freedom of information obligations, branding, consistency of user experience, support for multiple devices, and of course cost.

A new EA Repository

One of my goals since starting this job two years ago has always been to create a repository for architecture documents.  The idea is to have a central store where people can find information about the University's applications, data sources, business processes, and other architectural information.  This store will make it easier for us to explain our plans, to show the current state of the University's information systems, and to explain what Enterprise Architecture is all about.

It's taken a long time to reach this goal, mainly because we're often had more pressing and immediate work to be done.  The creation of a repository is one of those tasks that is very important but never quite urgent.  So I'm now very happy to say that we are in the process of deploying a repository and modelling tool.


This is the culmination of a careful process to select the most appropriate tool for our needs.  We began by organising several workshops to gather requirements from a rang…

A brief summary of our major initiatives

I notice that in 2016 I wrote 34 posts on this blog.  This is only my fifth post in 2017 and we're already three-quarters of the way through the year.  Either I've suddenly got lazier, or else I've had less time to spend writing here.  As I'm not inclined to think of myself as especially lazy, I'm plumping for the latter explanation.

There really is a lot going on.  The University has several major initiatives under way, many of which need input from the Enterprise Architecture section.

The Service Excellence programme is overhauling (the buzzword is "transforming") our administrative processes for HR, Finance, and Student Administration.  Linked to this is a programme to procure an integrated ERP system to replace the adminstrative IT systems. 

Enabling Digital Transformation is a programme to put the middleware and architecture in place so that we can make our processes "digital first".  We're implementing an API framework, a notification…

Business Model Canvas

A Business Model Canvas is a tool for mapping the core functions and capabilities of an organisation.  Compared to the Core Diagrams that I described in an earlier post, the business model canvas attempts to present more aspects of the business, starting with the value proposition – a statement of what the organisation offers to its users (in the business world, to its customers).  It shows the activities and resources, as Core Diagrams do, but also shows user relationships & channels, and also benefits and costs.  I’m not aware of any universities that have used this tool but you can find examples from elsewhere on the web.

We are considering business model canvases as a tool for mapping the strategic capabilities of units at the University of Edinburgh.  Phil Taylor, our EA contractor, sketched an outline of what a business model canvas might begin to look like for HR:
This is only intended to be suggestive: the real canvas would need to result from in-depth discussions about th…
