This book really is about Enterprise Architecture with the emphasis on the enterprise and not the IT architecture. Written by a frustrated practitioner it offers a cohesive while perhaps not as comprehensive as one might like methodology in a very compact 130 + pages including glossary.
The book starts with devastatingly simple proposition that "Enterprise-architecture is the integration of everything the enterprise is and does." It works for me. The first chapter establishes the methods framework a twenty five cell structure that maps Purpose, People, Preparation, Process and Performance drawn from a project management methodology against five "sideways views". These are Efficient, Reliable, Elegant, Appropriate and Integrated. While I kind of get the 5 Ps I kind of missed the "sideways views". I mean Elegant?
The lack of a foundational theory and the immediate progression to a framework is a little alarming particularly when the rest of the book is then dedicated to filling out the framework. Twenty five cells in about 120 pages (less than five pages a cell) with I must say a reasonable amount of white space at the end of many of the sections. Not surprisingly, there is not much meat to the tools and techniques used to fill out the cells.
Given its size this volume was never going to be much more than a set of architect's notes. But putting that aside and being impressed with it not giving into the temptation of becoming an IT architecture book, I have to be positive about this book. Small, concise and perhaps a little overawed by the concept of recursion this book tackles EA without falling for the IT trap.
This is a book as it says itself for chief officers, strategists and programme managers and I agree with that. This is not the book to start your collection with and probably isn't that much use to the average IT focused corporate architect. And frankly it's a bit pricey for what it is. But, is it worth a slot in your EA library? I'd have to give it a reserved yes. Not wishing to damn it with faint praise, it is what it is.

This is an interesting book. In a curious way it is almost devoid of an underlying theory, something I've criticized many methods and books for and yet it maintains a cohesion that is difficult to fault. This book is about models, decision and analysis techniques and that makes it quite a rare and useful volume. I am frequently dismayed by the poor analytical skills of architects that I encounter day to day. This book has the analysis process and its management as its central theme and manages to do it without becoming overly academic which is a bit of a triumph.
Think EA meets operations research and you'll start to get a feel for a book dedicated to rational (no not the IBM brand) enterprise information systems management. This is EA as decision support for the CIO. It discusses strategic issues like goal setting and decision alternatives and domain definition. It then takes these goals and breaks them down into properties and provides techniques for collecting evidence; a practice that isn't as well developed as one would expect in many organizations.
The authors support this approach with a huge number of simple, but thought provoking models just the kind of thing you need to get you working on your problems. My favorite is the credibility of evidence model. There's a section on intuitive EA assessment in which they manage to give the process a lot more structure and logic than the usual rubbish that passes for intuitive analysis. And the section on organizing for EA actually has more content than is apparent on first inspection. But you'll have to work your way through the models. Based on COBIT the EA as a process approach reminds me a lot of Spewak and Hill with the same directness and perhaps a similar failing to grapple with social realities.
The book only credits two authors on the cover however I counted about adozen contributors. The writting is clear concise if somewhat bland typical "Euro Architecture" style, but at 300 pages not too hard a read. This is not the book to base your practice on, it's not strong on governance or business integration. However, it is one of the best technique books you'll find. This is the sort of book that you'll reference more than read. Not a book for beginners or managers but obviously worth its place on your bookshelf.

The architecture of a software system defines its primary structural and behavioral organization. A well designed and clearly documented architecture is a crucial pre-requisite for the successful implementation of a software system as well as for its subsequent evolution. In this talk, we examine how the new generation of model-based software engineering (MBSE) methods and technologies can be exploited to facilitate the specification and enforcement of software architectures. At the core of MBSE is the use of higher levels of abstraction and greater use of automation compared to more traditional development approaches.Bran Selic is currently President and Founder of Malina Software Corp., and Director of Advanced Technology at Zeligsoft Limited. In 2007, Bran retired from IBM Canada, where he was an IBM Distinguished Engineer responsible for the strategic direction of IBM's software development tools. In addition, Bran is an adjunct professor of computer science at both the University of Toronto and at Carleton University in Canada. He has over 35 years of practical industrial experience in designing and implementing large-scale software systems and has pioneered the application of model-based methods in real-time and embedded applications. In the past decade, Bran has led several international standards efforts related to modeling technologies, including the widely used UML 2 modeling language standard. A frequent invited and keynote speaker at various technical events, he is on the editorial board of two major scientific journals and has been the general and technical program chair of a number of technical conferences.

Yesterday, I spent a good deal of the day reading and rereading the class action suit filed by the Robbins family against the Lower Marion School District. The suit alleges that the school invaded the privacy of Mr Robbins (who is 15) and other students of the school district. The schools had provided Mr Robbins and other students with laptops as a part of a program to bring e-learning opportunities to the student body. The laptops were installed with a webcam and can be remotely administered to take snapshots of whatever is in front of the camera. The system was installed to help track missing or stolen laptops but the case alleges that the schools used it for much more.
I believe this case represents a very significant moment for IT architects and technologists in general. The issues at stake are tremendously important and include the privacy and safety of minors, the potential for the abuse of privacy by government, security, as well as government IT policy which could impact millions if not billions of dollars worth of spend. There are so many elements to discuss that it would be difficult even to list them in a single post.
Let's start with a simple but interesting oversight on the part of the plaintiffs. They named 3 groups in the case; a) the school, b) the district and c) the superindendent of the school district. Many of you may not be aware but for some time I have been predicting that IT would begin being named in these types of cases. They did not do so in this particular case but other cases I have seen are leading us there. Here is a question, are any of the named individuals qualified to understand the privacy implications of a complex technology system? Even if your answer is yes, aren't the contractors and IT staff involved equally responsible and much more qualified for identifying and escalating such potential issues? If that is so, what is our (IT architects and IT staff) liability or culpability in these claims?
IASA will be following and pursuing the stakeholders in this case. In addition I will be forming a small leadership team to discuss these issues and what if any response IASA should make and where our responsibilities lie. I will be keeping you informed of any results we discover.
Follow up posts will include: IT architect liability and licensing issues, public inspection of IT systems, the 'doh! we didnt know response', and details on the case progression.
Every five to ten years the world of computer programming faces a new paradigm shift, like GUI, object orientation, or generics. Right now we are facing the paradigm shift of parallel/multi-core computing. Successful research in this area has been done for the past 30 years, but we are still not using the results efficiently. A pattern is a working solution to a recurring problem, and parallel/multi-core programming has its own problems which has led to a set of patterns. Come to a session about which patterns exist in the area of parallel/multi-core programming and how they can be used with Visual Studio 2010.

Srini Penchikala, Security Architect | SpeakerAgile Architect: Integrating Enterprise Architecture into Agile and Lean Software Development Enviroments
Srini Penchikala, Security Architect | SpeakerSecurity Architecture Policy Enforcement and EA Governance Using AspectJ and SpringAOP Techniques
In this presentation, I will talk about the significance of enforcing security architecture rules and how to implement an application security architecture governance process in software development projects. I will discuss a framework we created, using Aspect-Oriented Programming (AOP) techniques and tools like AspectJ, SpringAOP, Eclipse and AspectJ Development Toolkit (AJDT), to identify any coding deviations from standard security architecture rules and design policies. The security architecture enforcement module was created as part of the overall Enterprise Architecture Governance effort to comply with Enterprise Identity and Access Management (IAM) standards. The session will include discussion on how to enforce the security policies in the areas of Authentication, Authorization, and Role Based Access Control (RBAC) as well as Security Domain Driven Design and Factory Object patterns. It's also used to enforce the security policies at execution time when users login to the IT systems.

This presentation is about fundamentals. Layering is a basic concept of IT architecture. Layers help to seperate dependencies and to decouple concerns. Most of the industry does layering in name only. It's lip service. In these slides and accompanying commentary we will explore the concepts of layering and isolation of dependencies and it's impact on the success of your architecture. Speaker: JEFFREY PALERMO is the CTO of Headspring Systems. Palermo specializes in Agile management coaching and helps companies double the productivity of software teams. He is instrumental in the Austin software community as a member of AgileAustin and a director of the Austin .NET User Group.

As you can imagine I read a lot of architecture related books, blogs, news postings and watch even more presentations both online and at our IT Architect Conferences. Over the last couple of years Ive noticed a trend in EA presentations that claim there enterprise architecture is not necissarily related to technology. In this model of our profession, enterprise architects, model the business, or my favorite "architect the enterprise".
After 7 years of speaking with and leading communities of practicing architects throughout the world, there is much that needs to be said about this trend. First, let's deal with the language element. As my friend Richard Hubert has passionately described, the word architecture is a noun and not a verb. The verb that these folks are looking for is to design. I know, I know, you are thinking, "Paul that's just an expression. Why would you care about semantics?" Over these last 7 years I have learned to take language very seriously. Fundamental definitions impact the fabric of our profession. For example, in the expression "architecting the enterprise", mistaking the word architecting with design describes a profession where the word architecture is synonymous with design. I posted on this a while back, but if architecture is design then it is NOT a profession as ANYONE can design.
Another issue with this expression is the position it claims inside a business. If we are "architecting the enterprise", what are all the other business people doing? And what exactly does that mean? Does it mean if I create a business process model that describes our sales channel, it's customers and products with all the associated meta-data that I have "architected" the sales channel? If I propose a change to that sales channel have I then "architected" it? This definition of architecture starts to sound suspicious almost from the get go. It looks very much like "architects" moving to the head of the business table as business consultants. The only issue there is that we already have plenty of business consultants, MBAs, business executives, etc and they are not at all interested in us moving to the head of the table. They already have working models of the enterprise in the form of financial models, HR models, sales forcasts, and yes business process models. The folks that are recommending this are missing two critical factors in our profession; 1) it was technology that got us a seat at the table in the first place, and b) there are many thousands more technology architects in the world than there are non-technology architects (think 99% to 1%).
So where did the technology go? What distinguishes these folks from other business consultants? And most importantly to me, what value does anyone get from their use of the term architecture? Worse, are they doing damage to the concept of architecture as technology strategy? Building and maintaining a technology strategy for a company is a huge task. It takes a ratio of 6-10% architects to IT staff. It generates huge profits and enables that much more. So why do people continue to run away from technology as a key value proposition? For those of us that deliver a working technology strategy and don't 'architect the enterprise', there is enough work to do without trying to escape to 'the business'.
In this presentation we will walk through the basic elements and types of portal and the enabling technologies that make them possible. We will venture into portal frameworks, mashups, social media and much more. We review the introduction of different technologies and how they have impacted web sites and where you might be able to leverage them to drive your own business.

Able Architecture: Part II
Part II of Able Architecture continues to reveal my vision of Modern Software Architecture.
This is a small book with big ambitions. At only a little over 140 pages it is by EA standards a modest volume. But that shouldn't put you off.
The book presents a surprisingly comprehensive approach to EA with a simple and yet well structured theoretical foundation and enough practical detail to make it credible without overwhelming the novice. Written as a text book for an architectural course it consists of four main sections. These include the usual explanation for why we need EA, updated for the global economy and a little more stakeholder centric than the usual effort. Followed by "positioning EA" which is actually more like defining and describing EA and then two sections on the execution of EA.
One of these is the now a days almost obligatory case study / example, typically the refuge of people who can't actually explain what they mean. My initial reaction was to reach for the phone, order a pizza and turn on the football. But, surprisingly the situation was saved by an example with some real meat. Not only do the authors demonstrate their points, but they manage to connect them to both their own technique and broader well know concepts like Zachman's framework; all without becoming arcane. In 30 odd pages they deliver more value for the architect than many complete books.
They follow these sections up with a topic that should be getting more air play than it is "The Enterprise Architect". It seems that these days every man and his dog is an architect, frankly I wouldn't feed many of them. But, having said that it's no easy matter deciding what makes an architect. Well, this book has a good go at answering that question and even if you don't agree with the them there is a certain order and cohesion to their argument that must be respected.
This is a crisp clean work written in "Euro Architecture" style, which is not surprising given its origins. It will work for architects at all levels and will add value to any bookshelf. Recommended.
