Also, the title 'architect' has historically had some nice effect to it (pick any Vandalay episode from Seinfeld.)<br /><br />People like me, with 15+ years of programming experience, do not mind working as designers/developers, but do mind the 'factory' mentality corporates and management has developed towards old fashioned 'engineers' and 'designer/developers'. The only option is to tout a fake 'architect' to show that a person has considerable experience in a certain field. After a while, this becomes a mandatory requirement; employers 'weed-out' any developer resumes, as they think developers are under-qualified for a position.

Hence, culture of technology changes with time. Hence, technology architectures must change with time. Charles Darwin imparted a teaching we tend to forget too often – adapt or fade away.<br />It may be a lame example for IT architects, but the fact is that the architecture perceived to be BEST suited to the technological needs a few decades ago, does not seem to work as well today, and may be a miserable failure few decades later. However that does not imply that the architects who developed the methodology decades ago, did a terrible job at it. <br />The debate will spur to life every time an architectural model is forced to work in times different from the times it was invented in. Today the debate is between EA and Agile. <br />2. Then why am I of the opinion that that EA giving way to Agile is as natural as a frog developing webbed feet? Well, historically (in software that’s barely a couple of decades), developing software at the enterprise level was a gargantuan task, as it had never been done before. Each software development mission had to be well planned, complete, documented, reviewed, structured, designed by sharp minds at high and low level – EA was the need of the day. Then what has changed today? Proponents of the EA ask, don’t we need a holistic view, or quality programming, or a strong and studied structure? When these are ignored it sure isn’t pretty. So from there originates the thought of the new age Agile lingo being but a fad which may work in a few cases but not survive the test of time and diversity. <br />Aren’t we forgetting something here – agreed structure and design is indispensible, but business environment has changed, technology has changed. How? <br />•The client can’t wait for a year, or two or more for his product. <br />•The client does not believe that making the software is any rocket science now. Everyone’s doing it, doing it good and fast. <br />•The costs of large teams, sitting over a design for months, and code for years are forbidding, and not supported by the company’s stake holders.<br />•The competition is fierce; they are all getting modular, faster and cheaper. <br />•Economical volatility where markets fluctuate, capital availability varies, government policies changing were always here, but today the response time to the changes is shorter. This means, a client wants the software development firm to be accommodating to requirement tweeks. <br />•Are you capable of delivering a product in phases, first to meet my requirement today, as I grow with it, I will want it expanded in scope and functionality. Or is the product such a dump of intricate code that it’ll be another project altogether to upgrade it.<br />•The benefit of all the hard work of the yester years’ designs is up for grabs today. There are automated utilities built on the principles developed by the learning done the hard way. Why reinvent the wheel, because the wheel works great; rather focus on the gear assembly.<br />•Technology changes, even while the software is being developed. Can you keep up with that, to find the best balance between low cost, low effort and effective results?<br />3. So what happens when I have structure and design but in a manner that has adapted to address the scenario above. Do I have a winner for this age then? EA vs Agile in my opinion is misunderstood as holistic vs local. Let’s take EA first, it does start with a holistic analysis, but has to trickle the development all the way down to the most local aspects. Now consider Agile, say the Scrum methodology. It starts with a product backlog – prioritizes it to the release backlog – thereby staying focused on the core, and setting priorities based on the business value to the customer. How the team designs its sprints decides how they channelize their focus, if it’s a large system they’d probably dedicate a sprint focused on design and analysis. This in the true sense is the agility of the Agile. <br /><br />a.mendhi@gmail.comA Mendhihttps://www.blogger.com/profile/05817204036346885199noreply@blogger.comtag:blogger.com,1999:blog-2268998498114946821.post-62138016000232052622011-03-14T18:15:32.735+01:002011-03-14T18:15:32.735+01:00That's it.

You have made a valid point that often Enterprise Architect has no control and no power.<br /><br />Rather it takes a long vision of organisation higher management to understand the benefits and essence of EA. Often management, middle and high, do not understand that IT in an organisation is like a ship. It can be a wooden boat or a speedboat depending on how you need your ship to be. The speed and agility to support business changes fundamentally is limited to the design and build of the ship itself. One has to balance the cost of today’s incurrence to the benefits of tomorrow cost saving and business agility. Often management demands IT to produce quick solutions to support business changes but do not value IT as an intrinsic assets to the organisation growth.<br /><br />It may take more education and evidence for the management and the organisation to see the value of EA. Probably to implement technology architecture (TA) for a start take involves less of business processes and business users to showcase the benefits of EA. Then move on to other areas of EA and gains valuable support by the management before EA truly establish its value in the organisation. Enterprise Architect in some degree has the responsibility to play such a role in the organisation. It is only when hearts are won then your people will follow your vision and mission.<br /><br />For your cited examples that management walking out of EA presentation throwing away the EA materials only mean that at the current stage they do not understand and does not want to take part of EA. They are just not ready now but it does not mean EA is a failure. They may not be ready now it but does not mean that they will never be. EA in and organisation is ever evolving and has no end. EA may solve/control systematic problem in an organisation and truly brings about greater business efficiency. <br /><br />Agile EA as what you have suggested may after all be a good strategy at least for a short term. At least some degree of EA is performed and organisation is not losing too much ground in EA perspective. However one must also exercise caution not to procedure silo EA then ultimately defeats the purpose of EA.<br /><br />Derek SumUnknownhttps://www.blogger.com/profile/17830921661138769305noreply@blogger.comtag:blogger.com,1999:blog-2268998498114946821.post-22724991705292827522011-02-03T07:28:21.337+01:002011-02-03T07:28:21.337+01:00Great topic, thanks for that.

You're right on target that enterprise ...Mike,<br /><br />You're right on target that enterprise architecture isn't working. To see why, see blog site tmiconsulting.wordpress.com. Although this site focuses on the U.S. Federal Enterprise Architecture, it exposes the underlying problems of EA everywhere. The bottom line is that most of what EA calls "architecture" ISN'T architecture.<br /><br />A quote from that blog:<br /><br />"The solutions to all of these problems are actually very simple, but most people can’t see them because they’ve been blinded by “illusions of architecture”:<br /><br />Before we can solve these problems, it needs to be made clear that the practice of Enterprise Architecture has offered us nothing that wasn’t already available to us before in our pursuit of a federal-level understanding and management of all federal IT resources. In fact, EA not only didn’t help us in this pursuit, it has actually hindered our progress.<br /><br />In our quest to “do architecture”, we have been misled by illusions of architecture. We have cast aside simple yet effective IT terminology and methodologies that have been in use for decades, and have replaced them with new but ultimately misleading terminology and bloated methodologies that are at times more complex than the problem being addressed.<br /><br />We have replaced simple, intuitive, and long-used terms like “functional area” with dense, obtuse terms like “Segment Architecture” that only manage to confuse, and have developed a corresponding methodology that defies comprehension and does little to actually help us analyze a functional area.<br /><br />The simple truth, if practitioners would only take the time to look into it, is that most of enterprise architecture is a facade that hides the simple solutions we need behind a false veil of “architecture".Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2268998498114946821.post-7936309984783160022010-12-29T15:38:04.768+01:002010-12-29T15:38:04.768+01:00Mike,

It is interesting to read so many article on problems with EA and the frustration of EA specialist. It is so interesting that I have directed research activities towards a new generation of EA - named ESA - Enterprise Systems and its Architectures. (ooh yes, me too :)<br /><br />The assumption is that the current set of EA framework didn't get it quite right. This based on all the problems reported in the area of management non-buy-in.<br />Clearly an application of a EA framework is a Mean to some Ends. Most EA are developed by and for IT people, based on the assumption that what they work with is important and of relevance to the organisation. Unfortunately outsiders (to IT dept) are often reported as unconvinced of it. Especially why EA concerns are of interested to them. <br />An Example from a real large B€ project where the operational people are told that SOA is how they should view services. But then relevant (to them) concerns such as (IN/OUT)sourcing falls outside the framework.<br />So does EA really talk business?<br /><br />food for thoughts<br />/anders w. tellAnders W Tellhttps://www.blogger.com/profile/13784012221437922197noreply@blogger.comtag:blogger.com,1999:blog-2268998498114946821.post-35826439062300830392010-11-06T13:39:41.027+01:002010-11-06T13:39:41.027+01:00Hi:
