A nice discussion was going around Is EA your center of Excellence? and another one Why EA is Joke. I would like express my point of view, I feel EA is not a joke. Actually it is a challenging and interesting job. Again but, sometimes EA forgets that they are working to add value to the company. EA itself become a silo in a company. With my little experience, I would propose a small solution for a problem - EA group should understand its Customer within a company. Organisation could be complex or simple, depends how you look at it. And EA could consider diverse teams its valued customer. Looks complex task but may not be. Often EA team starts with 2 to 5 people with lot of expectations. And as they are not able to deliver to all its customers and finally vanish. I feel start with small team and create a charter, proper communication interfaces and communicate properly. After a while start increasing the number of people and start serving to all the customers. It could be group of architects serving to different teams like Business, Delivery, Infrastructure etc. And same team participating in effective IT Governance and initiating challenging technical projects for the Business problems in virtual teams.

IT Governance improves the efficiency of Enterprise and manage the risk. There are different standards like COBIT, ITIL, Six Sigma etc which provides more detail.
May be we could divide the Governance in different categories like Portfolio Governance, Project Governance and Architecture Governance in an organisation.
Portfolio Governance helps to prioritise projects in pipeline, conducting cost benefits analysis, measuring business value, managing risk, defining effective process, initiating right concept and proposals.
Project Governance helps to steer the project towards the expected outcome, improving quality, aligning everyone to shared goal, revisiting the business value, delivering the right solutions.
Architecture Governance helps to build the future, identifying the opportunity, preparing road maps, migration plans, gap analysis, documenting current state, governing Enterprise Initiatives like SOA, Web2.0, EDW, Virtualisation etc.

TOGAF framework provides good ADM process to develop Enterprise Architecture in the organisation. It provides the insight to the IT Architects who most of time focus on Technology Architecture and remain ignorant about the Business and Information Architecture.
I feel most of people in IT industry relate Enterprise Architecture to Technology Architecture.
And may be most of Enterprise Architecture programs in organisations keep doing the Architecture Domain analysis. And never able to effectively prepare Migration Planning for the Architecture. It is not easy task with ever changing landscape in Business and IT.

Its a good beginning for me to understand the Mutual Fund business domain. In my view, Enterprise Architect role demands good understanding of Business Architecture. And to add more, its easy to read the architecture domains as described in TOGAF framework as compared to analyse the complexity of inter-relationship between the architecture domains.
I have seen Enterprise objectives, vision and goals for very few companies and they look more or less same. And its interesting to find the pattern on how these are related to initiatives in the different Enterprise.
Another interesting place to find pattern is between the mapping of the Business process, applications and technology stack. And for the similar kind of business process in different business unit of same Enterprise which all applications and technology stacks are used.
Interestingly, I am still trying to identify the similar resolution pattern for the identical recurring problem at conceptual level in different units of the Enterprise.
May be Enterprises needs to define Architecture Policies, Standards, Best practices to abolish the pattern of re-inventing the solutions for the recurring problems at Enterprise level.

I don't understand the intricacies of RIA and I am not expert in it. But I understand fundamentally that Magic lies in Asynchronous XML messaging. It provides perception of site with hyper intelligence. There many flavours of RIA available in the market. Few famous one's are Adobe Flex, Microsoft SilverLight and JavaFX.
Now the challenge for an Enterprise, it is still emerging technology and not based on standards. Is it ready to be introduced in mission critical production environment? Benefits comes with calculated risk. Enterprises need to adopt these AJAX based technologies in less critical applications. Few examples of such selected applications may be for survey, selection of product, search screen, choice based on criteria and wizards. And above all, try to keep the number of AJAX toolkits as low as possible in Enterprise.

Let try the same analogy in big enterprise. A developer working in a module of project. Module is kind of world to him. How his work impact the the whole project. This project is part of some program. Program is run by some business unit. Business unit belongs to some vertical. This vertical is part of regional unit. This regional unit again reports to headquarters in country. Country is just one of countries where MNC operates.
Is it possible one person, one team, one group, one unit creates ripple effect to make the Enterprise better? In the last I remember a quote, if you don't make a difference, you don't matter !!

Furthermore, Strategy could devised at different level in organization for different purposes. It shows the path to reach the identified goals. Mostly organization devise corporate, business and system strategies.
Lets try to understand business strategy - It frequently contains simple and common objectives like generate revenue, increase profit margins, reduce total cost of ownership, improve stability, increase agility, create brand value, focus on people and processes, deliver results, innovate, become leader in flat world, motivate people to drive organization and lot many similar things.
On similar lines, IT drives the Technology strategy from Business strategy. It plans the future road map from current roadmap, create plans/steps to reach the long term objectives, better align with the business directions, increase reliability and availability, improve service levels and create governance mechanism.
Strategy looks quite common sense and most of companies have strategy in place on similar lines. But not all companies are excellent and growing at tremendous pace. What else is needed for business to succeed? May be a excellent implementation of strategy, people who believe in strategy, leaders who keep the whole team moving together in right direction and selection of right strategy at right time.

7-S model define the various elements which forms the organization. I am still trying to understand the various stages in the life of any organization. Is there exits a trend for stages during life of Organization? May be on the lines of Tuckman's team model.
Another team model worth reading is Situational Leadership.
Experience matters more than any theoretical knowledge. I think in Architect role, we get lot of opportunity to hone leadership & process management skills but people management skills take a backseat. In my view, People management skill is also important in long term and one should find ways to develop it.

Sergey Brin and Larry Page are people of principles and beliefs. They have reaped benefits of economies of scales. Google is default search engine and have unique position. Power of Google lies in
- Search Engine business case i.e. Information and Search significance are directly proportional to each other, both are growing at fast pace.
- Secondly, in having a winning edge on technical front. Mammoth hardware clusters and creative software to harness the power to generate lightening results.
- and in the last, they are able to build a big brand name associated with high integrity, values and reach.
Lets end this blog entry with Google Motto "Don't be Evil".

Quite opposite to study conducted by Gartner and trend suggest that weekly hours will reduce.
MOE is basically a type of culture prevalent in Enterprise. In this type of Enterprise, there exists lot of committees. Every decision is approved by hierarchy of people. Decisions are based on big reports. Long discussions take place to improve the efficiencies. Every big enterprise has processes. In this enterprise, employees follows all the processes to complete milestones. It helps to check the progress but the value of each step in process is not evaluated. Employees just complete the activity to tick the completeness. Delivery is primary focus.
LOE is another type of culture prevalent in Enterprise. In this type of there exists Leaders. Leaders at all levels. These Enterprises also creates lot of small committees. These committees come up with small action items. They believe in pilots, POC, prototypes instead of big reports. Long discussions too happens but with actionable outputs. Processes are followed and employees try to add value in each step. Quality is primary focus.
Somehow, I feel MOE adopts top down approach of SOA and LOE adopts bottom up approach due its culture. A push for top down in LOE is going to be much more successful than in MOE.

Think of a Country which is composed of States. And there is no central governance present, what will happen to States. Few States might be able to self govern, few will loose direction and few will become rogue States. With time, it will become difficult to manage the Country as a whole. Vision of country will be blurred and lost. States won't be able to leverage each other strengths. States will try to run their own charters and soon forget that they are part of Country. Most of States will have their own priorities, goals and budgets.
Still not convinced and think that Governance is overhead in a Country. Just for information, check the link Somalia , which is the only country in the world where there is no government.
Now just replace the Country with Enterprise and States with Projects. Hope you understand that missing governance in Enterprises is one of most common reason for complex IT state.

Explaining my point with scenario like execution of Single Service -
Consider scenario where prepaid caller dials a called party number. A event is generated, service capture the calling party number and called party number. Based on called party number it routes the call. Now caller listens the ringing. Called party picks up the phone. Another event is generated. Service captures the events and starts charging. There is voice channel between caller and called party. After sometime, called party hangs the phone call. Another event is generated and service based on this event stops charging and persist the duration of call. In this flow, based on current event and last event result, application service executes the business logic. There is requirement for storing the state of call. This makes scenario little bit complex. Events cann't be consider stateless in real sense.
Execution of Multiple Services
In this case, one approach is to introduce Service Manager and this Service Manager further manages the interactions with several services and their sequencing.
In contrast with Enterprise application, Telecom applications are more chatty i.e. Events are too many and are of very short duration. Due to this, scalability and performance becomes burning issues. Secondly, all these events are in real time. While events are processed, customers are waiting for call to connect, waiting for ring back tone, announcements etc. It makes true testing ground for EDA.
In last, I feel, SOA and EDA could change the landscape of Telecom services. Niche companies could provide services like charging, rating, application services on internet. These services could be consumed by operators instead every one building themselves. Telecom domain is always a front runner at concept level. Hub & Spoke model of Telecom switches was innovated three decades back. This model is foundation for buzzword ESB nowadays.
"That man is successful who has lived well, laughed often, and loved much; who has gained the respect of the intelligent men and the love of children; who has filled his niche and accomplished his task; who leaves the world better than he found it, whether by an improved poppy, a perfect poem, or a rescued soul; who never lacked appreciation of earth's beauty or failed to express it; who looked for the best in others and gave the best he had." - Ralph Waldo Emerson
