New Pointer Set:

No, we are not unique! Some Pointers to state levels of architectures (with some to counties and cities):

In an attempt to see what was out there (on the web) for Enterprise Architectures I did a series of searches on the following key words: Enterprise Architecture, Technology Architecture, Enterprise-Wide IT architecture and various other key words it the address suffix of .us.

This did NOT find all the appropriate sites but I did get over 1000 hits from the following states: AK, AR, AZ,CO, CT, DE, FL, GA, IA, IN, KS, KY, LA, MA, MD, ME, MI, MN MO, MS, MT, NC, ND, NE,NJ, NV, NY, OH, OR, PA ,RI, SC, TX, UT, VA, VT, WI, WY.I refined the number of sites to about 250 table entries, of which I have not had the opportunity to refine the Wisconsin and Wyoming entries yet.These last few will be validated over the next couple of weeks.

Arkansas, Connecticut, the City of Indianapolis, Kansas, Kentucky, Massachusetts, Montgomery County in Maryland, ME, Minnesota, Montana, North Carolina, Nebraska, New Jersey, Ohio, Oregon, Utah, and Virginia all have web resident Architectures.†† The other states are in the process or at least appear to understand that EA is necessary.It is noteworthy, that the primary type of EA is that style sponsored by MetaGroup.This Pointer list is about 500k bytes, the pointer list on the EWITA site, just go there and select LINKS


Technology Trends:

Extracted from the CA/EDD/BDA, request full access to the BDA at CA/EDD Complete Architecture


Technology Trends


The technology trends are widely recognized forces or directions of change in the IT industry. These trends identify the most important technology indicators impacting the organization and the enterprise architecture. The Architecture will utilize trends to frame the development of the technical architecture in the context of current technology and to understand the impact of technology on the organization's business drivers and architecture requirements.

The Archtiecture team ranked these trends by decreasing importance to organizationís business drivers and the Architecture.

Network Centric Computing. The need to share information efficiently with customers and partners, as well as internally, will cause electronic document handling, electronic commerce, automated workflow and collaborative computing to continue increasing dramatically through 2001. Intranets and the Internet will become the de-facto standard delivery mechanisms to enable information sharing and collaboration. These developments, along with the distribution of computing services (i.e. client/server applications), will increase the demand for network connectivity and communications bandwidth by up to 300%. This trend elevates the importance of the network and makes it a critical factor in the success or failure of an organizationís business processes.

Resource Challenges. Shortages in personnel, time, and outsourcing resources will drive 3%-4% monthly IT cost increases through 2001. Government organizations, unable to keep pace with skyrocketing salary requirements due to flat or declining budgets, will be acutely affected. Organizations that have difficulty attracting and retaining IT professionals cannot afford to invest resources into niche oriented, leading-edge products. To address this situation, successful organizations concentrate on using market dominant providers for their technology solutions, thus ensuring a broader labor pool.

Internet/Intranet. The Internet and its capabilities are becoming a universal business communications medium. They will drive standards for network computing, collaborative computing and electronic commerce. During 2001/2002, development using these tools will focus increasingly on legacy/enterprise application integration and mission critical (e.g. systems that require a high level of reliability, availability, scalability) Intranet/extranet applications.

Data Warehouse. The need to accelerate decision-making causes organizations to put operational data from the lines-of-business into data warehouses that provide enterprise-wide views of information. Powerful, yet easy-to-use, GUI analysis tools in the hands of decision-makers will provide them with immediate access to key information. Information from the data warehouse will continue to be electronically disseminated to knowledge workers within the organization, external business partners and customers.

Security. As organizations increase information sharing and access to data for customers and partners via the Internet, the complexity of securing information is increasing. The lack of encompassing security products/standards will hinder the ability of a single all encompassing security solution. This will cause selection and implementation of various enterprise-wide security solutions based on specific local factors. A demand for single sign-on, (one user log-on Id.), will drive development of security infrastructure with auditability, authentication (smart cards), and strong identification (fingerprint, voiceprint , etc.).

Total Cost of Ownership (TCO) of IT. Because of the rising costs of IT support services and personnel, organizations are over engineering their technology infrastructure (hardware, software and networks). By 2001, successful organizations will emphasize the use of standards and "best practices" to reduce integration complexity rather than optimize the performance of individual infrastructure systems to reduce TCO.

Technology Price/Performance Curve. Innovations in the technology industry will continue to lower price/performance curves. Computer processing speeds will continue to double every 18-20 months. Network transmission technologies promise to deliver dramatic increases in network transmission capacity (bandwidth) and lower costs. Costs of computer memory and the electronic storage of data are decreasing rapidly.

Mobile Connectivity. The demand for information by mobile users is increasing as the ability to provide personalized customer service (at the point of customer contact) becomes a strategic competitive advantage. Successful organizations design infrastructures with remote access in mind. This drives organizations to develop enterprise-wide remote access solutions. The need for mobile connectivity will help increase the use of wireless technologies 20%-30% annually.

Systems Management and Support. Growing personal computer use, dramatically increasing network traffic levels, Intranet applications and expanding complexity of IT systems will drive cost increases related to systems and personnel support services. Organizations are implementing enterprise-wide system management solutions and service-level agreements to control these costs, and also to improve reliability, network availability and disaster recovery.

Client/Server Application Development. The Client/Server model of distributed systems will continue to grow. In this model, the dominate industry trend is to separate, at minimum, the data access, business-logic and presentation parts of the application. Centralized legacy systems will continue to be a primary service delivery for high transaction volume production-oriented applications. However, increasingly, legacy data will be interfaced into new client/server and web-enabled browser-based applications.

Organizational Dual Discipline Proficiency. IT has become an integral component to nearly all business processes. The information content of products and services is becoming a primary critical success factor in most organizations. This forces organizations to recognize the impact and importance of cross-training IT professionals and business managers. IT professionals have a solid understanding of the drivers and requirements of their business customers. Business managers are versed in current technology issues and trends that affect their organization.

Application Development Tools. Stand-alone tools used for limited, specific purposes lose market share as the environment in most tool categories is consolidated around integrated tools from a few, significant vendors. Legacy system support and application maintenance will continue with most of the same tools as used today.

Buy vs. Build. Buy for competitive parity, build for competitive advantage. Through 2001, organizations will want to buy commercial applications before they build functionally equivalent versions because of time-to-market pressures. Additionally, the rising cost of IT staff has increased the time to recover the costs of applications developed in-house.

Outsourcing. Organizations are increasingly utilizing external providers for selected IT services. The areas organizations most commonly outsource are:

Data Center Services and Network Services (wide-area networks and remote access)

Application Maintenance (legacy code updates/minor enhancements)

Implementation of Package Applications and Custom Application Development

Distributed IT Services (help desk and PC asset management).

> Hi Jonas,
> This is a simple question with a not-so-simple answer.
> An application architecture is part of the IT-architecture within the
> architecture of the information infrastructure of the organisation. When
> looking at the application architecture you have to distinguish between the
> current situation and the future situation.
> Looking at a current situation you look at what you have. This is usually a
> legacy of interrelated applications which is difficult to portray and, in my
> opinion, not standardisable. The problem is usually the grouping of the
> applications you have to create an architecture you can "handle". Another
> problem is the number of interfaces between the applications and with the
> environment.
> Looking at the future situation, and I mean way ahead, you can envision an
> "ideal" application architecture. By introducing some groundrules it is
> fairly easy to build it up. Say, for instance, a groundrule is that you only
> identify structured data ("databases"), unstructured data ("documents") and
> "loose" data (the data that is not managed but floates around in directories
> etc). If you make this the Data Architecture you can put functionality on
> top. This functionality will become your application architecture.
> Just looking at ERP, for instance, doesn't do the trick. ERP will do at most
> 30 to 40% of your processing, no more.
> Going some steps further introducing an application architecture and a data
> architecture is not the main concern. What you want is an (enterpise)
> information architecture. Here we find the conceptual models of
> functionality and information. Here you will find everything just once.
> Relating your application and data with your functionality and information

> an organisatioon wants to own.
> With regard to the conceptual models there are standards available. I do see
> some good practices, but hardly any standards on application architectures

A question from the Federal Architecture area

Subject: Architecture Items - Tools, February 28, 2001

> I would like to get your comments on the following tool alternatives:
> Alternatives Analysis
> Alternative 1: Select a single tool, and through the tool's meta-models
> enforce the rules and constraints associated with the products developed by
> the bureaus.
> Alternative 2: Select a standard set of architecture tools. These tools
> will be used to enforce the rules and constraints associated with the
> products or diagrams. Again, enforcement will be through standard
> meta-models. (Building diagrams in two tools will complicate the analysis.
> Some tools may be better for certain products than others; for example, I
> was told that the Operational Event/Trace Description and the Systems
> Functionality Description, which are both in the DoD and Treasury
> architecture frameworks, are best developed in UML.)
> Alternative 3: Others might argue that a standard tool(s) is not possible,
> and suggest that the bureaus use whatever tools they want as long as they
> produce the representations in accordance with the TEAF. The work products
> should be accessible to everyone in the agency; therefore, the products
> must be put in some kind of common form (e.g., html, pdf) or delivered to
> an agency common repository which would be accessible to everyone.
> Otherwise, some of the work products may end up in some softcopy format
> that you must purchase the tool in order to read. (A repository approach

> suggested that the vendors save to a standard format (other than html and
> pdf); although it is unknown whether this is likely to happen.
> What is a meta-model: The meta-models define the types of analysis that
