I note interesting debates about the need for a next-generation EA framework. However I am disappointed by the less than radical nature of debate that, at least I, have observed. I submit a good place to start is with the fundamental nature of business and how it is evolving and to consider what the enterprise of the future looks like. There are many indicators that we are entering a new phase of IT exploitation that will represent a real paradigm shift. Paul Krugman suggests IT is at last becoming significant, enabling a technology revolution to rival previous technology revolutions. Krugman cites driverless cars as an example of the technology moving into the physical world that has the potential to power growth. I will also instance a wave of disruptive technology delivering high bandwidth always on connectivity for billions of workers and consumers, mobility, BY... (more)

Time to Rain on the “Cloud Service Model” Parade

The Cloud community have been talking recently about Everything as a Service; they call it EaaS. At first hearing it’s an interesting idea, another acronym to complement IaaS, PaaS and SaaS.

However in order to read the document you have to suspend all your knowledge and belief of serv... (more)

Agile Enterprise Patterns

How do we integrate Agile projects into all the enterprise frameworks such as enterprise architecture, life cycle infrastructure, inter project coordination, systems deve... (more)

Agile Architecture

The English language is well known for its subtlety. Sometimes it’s a delight, but on other occasions it can be very frustrating. If I use the term Gothic Architecture you will immediately understand I am describing a style of architecture that flourished in medieval times. And if like me you are interested in ecclesiastical architecture you will know that this style was used in many of the great cathedrals and churches across Europe, which were distinctive because of key architectural patterns that enabled great increases in height and internal light of the buildings without inc...

Agile Business Modeling – The Core Heuristic?

How many times have I heard that the real problem with Agile is getting to the start line? There has to be some definition up front, but Agile methods don’t really help. Perhaps it’s a little secret for many organizations that they feel they must do more specification work up front because it makes it easier to control the Sprints. Oh dear! To get to this starting gate we need to model the agile business in an Agile manner (YES!). Further we do not want to undertake complete or detailed business architecture (NO!!). We don’t have time, and anyway the core of the innovation and a... (more)
