Aggregated enterprise architecture wisdom
In my last two blog posts, I have outlined a five-scale classification of system views and elaborated on the systemic-structural underpinnings of each view. As these systemic views are increasingly expressive and powerful, they also call for progressiv…
Here’s one of my favorite pictures of bad architecture that I use frequently in my presentations to non-architects. These pictures are from an elevator at Terminal 3 at JFK. Clearly there are at least three departments at JFK, each with … Continue reading →

What would you get if you put a drop of sewage in a barrel of wine?
Pretty much the same thing you’d have if you put a drop of wine in a barrel of sewage. i.e. sewage. Personally, I wouldn’t drink from either barrel. There is something to…
This one started from a Tweet from Vince Outlaw, one of the attendees at the recent Gartner EA conference in San Diego:

The Essentials While working with the concept of Enterprise Architecture it usually becomes a necessity to chose and implement a framework. As such the chief architect can either implement a standard framework, and as such commence the project of documenting … Continue reading →
Yep, another somewhat-delayed collection of Tweets and links. Usual categories, of course, after the inevitable (and necessary) ‘Read more…’ link.
Enterprise-architecture and all that business-ish big-picture stuff:

A Simple Answer to “What Is Billing?” | Doug Newdick’s Blog
“In my last blog post I talked about what #sexybilling was, or perhaps more accurately , what it might look like. It became evident from the comments though that I hadn’t really made it clear what I thought billing was, and so that sort of complicated the story. If we don’t know what billing is, how are we going to know what sexy billing is?”

How to get Ahead in Enterprise Architecture by Drawing Boxes – Simplicable
“Last week I spoke with the chief architect of a large international retail bank. This bank was able to reduce their application map from 160+ systems down to 5.
How (you may ask)? The answer is simple — by drawing boxes around them.”

The real (potential) impact of SAP HANA
“Much has been written about SAP HANA. The technology has been variously described as “transformative” and “wacko.” Well, which is it?”
“In-memory databases take advantage of two hardware trends: a significant reduction in the cost of RAM, and a significant increase in the amount of addressable memory in today’s computers. It is possible, and economically feasible, to put an entire database in memory, for fast data management and query. Using columnar or other compression approaches, even larger data sets can be loaded entirely into main memory. With high-speed access to memory-resident data, more users can be supported on a single machine. Also, with an in-memory database, both transactional and decision-support queries can be supported on a single machine, meaning that there can be zero latency between data appearing in the system, and that data being available to decision-support applications; in a traditional set-up where data resides in the operational store, and then is extracted into a data warehouse for reporting and analysis, there is always a lag between data capture and its availability for data analysis.”

A great conversation yesterday evening with a former colleague from Sydney, Robert Phipps. Rambling over a range of enterprise-architecture themes: about the distinctions between organisation and enterprise, about the role of values in the defining vision (or ‘venture’, as he put it – a useful term), about the flow of value around the shared-enterprise, and […]
