Comments from the Editor
==========================================================

Today I attended a presentation by Tim Landgrave on what it is to be an architect in the world of computers. It seems that a lot of people over the last few years have added the term 'architect' to their business card, yet when you ask people what an architect is, you can get a lot of differing answers.

I'm not sure that the presentation I attended today helped to do the best job of clarify what an architect is, or isn't. It did, however, hit on a number of points that fall into the realm of an architect's responsibilities. In doing this, a great question was asked:

What top three new technology trends will impact your organization on the next two years?

This was a great question that got a lot of good responses. If you read sites like DevX.com or Developer.com, then you can likely name many such technologies. AJAX was one of the first mentioned. SOA, SaaS, VoIP, RFID, and wireless communications were other items mentioned. I'm sure you can list several others that might impact your organization.

Once you've listed these, then there is a follow up question:

How can these trends be used as a competitive advantage for your organization?

This is an interesting question. Many developers fall into the trap of believing that you need to implement the newest technologies because they are, well, new. Being new, they must "save you time and money" and will make it easy "for you to be more productive".

Of course, this is marketing at its finest. This type of logic has been used by marketers for decades, and strangely, many developers believe it is true. What, however, is the real question? How will this give you a competitive advantage? Saving your time doesn't necessarily equate to a business advantage.

The discussion of technological advantage needs to be viewed from the same perspective of other business advantages. At its core, business is a focus on revenues minus expenses equating to a profit. If there is no profit, then there will be no business -- at least not for very long!

So how do the technologies you believe will impact your business lead to greater revenue or less expenses so that you can in turn realize a greater profit? Part of an architect's job should be to help clarify and support such realizations. If you can't quantify how a new technology will increase revenue or decrease costs, then you probably shouldn't be using the technology.

The role of architect is becoming more visible. Justifications in using new technologies are just one part of the role. Over time this role will become better defined. In the mean time, the role is one that should focus on the core business rules as well as helping to solve the right problem at the right time.

... Birthdays ...

Normally we don't point out birthdays in the newsletter, but there are two very special birthdays that have recently occurred.

The first is for Bob who entered the world about 12 years ago. You might remember Microsoft Bob. He was an innovative look at user interface design that didn't sit too well with humans.... Bill Gates later married the person running the project; however, it is not believed that there is a connection between the two events....

The other birth date worth noting is that of Visual Studio. Visual Studio has just hit the decade mark -- it turns 10.

Until next week...

Brad!
Special thanks to Tim for his presentation today.
