Architects face many challenges in their jobs. Among them are creating architecture and applying architecture. I’ve said many times that creating architecture alone does not create value. Rather, the value from architecture comes when it is applied. In other words, value is delivered when architecture is used to influence the outcome of decision making, analysis, design, or implementation. Yet another challenge is that architects are often not the people who are responsible for doing the applying. So we face a conundrum: we don’t create value until someone else uses the architecture. That begs the obvious question of how to get other people to use the architecture. The equation itself is really quite simple: if you Read more

Starting in 2011, look to a gradual shift away from constraining or contrived architectures, based on outdated analogies with building architecture or the traditional business, application, data/information, technology architecture EA “stack”. Tomorrow’s IT architectures may be more like the analogy where a building is architected in Zero-G (gravity). In such an environment, would we really pour the foundation first, and then establish the support beams and framing to be pre-requisite, dependant, and therefore locked in, for the life of the system? IT architectures — especially application and information architectures based upon emerging Semantic Web-based technologies — are far less constrained, allowing for refactoring, growth, and evolution in a real-time manner. There is no lock-in to Read more

When EA originally emerged, it was a thin layer of technology and methodology sandwiched between two large buns: business applications on the top and infrastructure on the bottom. The bulk of the headcount and budget of an IT department would be devoted to the acquisition or development and support of applications and to the investments in data centers, user PCs, network connections, and security.

The State of EA in 2010

Enterprise architecture (EA) has become a mainstream activity in large or information-intensive organizations. Several years ago, Cutter IT Journal covered the emerging best practices in EA, and since then readers have requested that we check back to explore how things are evolving. What are EA programs focusing on in 2010 and beyond? Well, what has changed since then? In the past few years, the industry has seen a lot of flux: outsourcing, “the cloud,” Enterprise 2.0, Zachman Framework 2.0, TOGAF certification, a maturing definition of business architecture, the financial crisis, and new priorities. How have these affected EA in different organizations? What activities are they focused on now? What are the new issues? Not surprisingly, Read more

I live in the state of New Hampshire. It’s a major pumpkin-growing region of the country, and October is harvest season. Truckloads of pumpkins head south and west, and local farm stands are bursting with the orange globes. But what do you do with all the misshaped or leftover pumpkins? Chuck ’em, what else? A local farmer has turned this into an art with his World Champion ‘Yankee Siege’ Trebuchet. This is something you really must see to comprehend. The top of the mast rises to more than 60 feet, and when the 12,000 pounds of weight are let loose, pumpkins fly for about 2,000 feet. Now, it turns out that this farmer is not Read more

Coffee, Loosely Coupled

A few weeks ago, I had a little electrical incident at my house. After the fire department left and the mess was cleaned up, we took stock of the damage. Except for the offending surge “protector” that caught fire, our UPCs pretty much did their job. No computers were damaged — just a dead scanner, a zapped paper shredder, fried cordless phone, and, most frustrating of all, an ex-coffee maker. I really like coffee … a hot cup of joe for breakfast, espresso in the afternoon, coffee to take in the car, iced coffee on a hot summer day, coffee for entertaining — you get the point. I had already been suffering coffee cravings because Read more

A primary function of IT architecture is managing change. This change happens at varying rates in and between levels of abstraction (think of wind moving at different speeds at different altitudes). So we can think of “horizontal” change — change in time within a particular level — as well as “vertical change” — the relationship between one level and another. A robust IT architecture maximizes the potential for improvements in all levels while minimizing the negative impact of change between levels. Sometimes IT architecture emerges through acquisition. In the old days, vendors imposed architecture that was bundled with their software development products. (Why would anyone have otherwise considered something like systems application architecture [SAA]?) As Read more
