...Article Essential Layers, Artifacts, and Dependencies of Enterprise Architecture By Robert Winter and Ronny Fischer Abstract After a period where implementation speed was more important than integration, consistency and reduction of complexity, architectural considerations have become a key issue of information management in recent years again. Enterprise architecture is widely accepted as an essential mechanism for ensuring agility and consistency, compliance and efficiency. Although standards like TOGAF and FEAF have developed, however, there is no common agreement on which architecture layers, which artifact types and which dependencies constitute the essence of enterprise architecture. This paper contributes to the identification of essential elements of enterprise architecture by (1) specifying enterprise architecture as a hierarchical, multilevel system comprising aggregation hierarchies, architecture layers and views, (2) discussing enterprise architecture frameworks with regard to essential elements, (3) proposing interfacing requirements of enterprise architecture with other architecture models and (4) matching these findings with current enterprise architecture practice in several large companies. Keywords enterprise architecture, architectural components, architectural layers, architectural views, interfaces ENTERPRISE ARCHITECTURE: DEFINITION According to ANSI/IEEE Std 1471-2000, architecture is defined as the “ fundamental organization of a system, embodied in...

...ENTERPRISE ARCHITECTURE Author: Institution: Date of Submission: Introduction During the early days of computing, the new technology simply automated the contemporary manual processes with increased efficiency. As the new technology continued to evolve, new innovations paved the way for introduction of new processes and capabilities that were largely driven by information technology. Over time, information technology altered the business environment though not necessarily in conformation with the conventional business strategies. The resulting lack of alignment precipitated unanticipated loss of resources and missed opportunities, thus placing most organizations in competitively disadvantaged positions within the market. In order to align the business strategies with organizational objectives, a new approach for managing Information technology has been established. This new concept is referred to as Enterprise Architecture. Enterprise architecture refers to ways or means of describing organizational structures and processes that link the individual business structures. It is the practice of applying a rigorous and comprehensive method for illustrating a current or outlook of a business’s information systems, processes, personnel, and the business sub-units so that they can be in conformity with the organization’s key objectives and strategic direction. This means that enterprise architecture is a strategic information asset base that...

...I believe the one technology that could have the greatest impact on enterprise architecture in U.S. corporations by 2023 is cloud computing. As indicated on the hype cycle for emerging technologies in 2013, it currently is in the trough of disillusionment; however, I believe that cloud computing will bring about the most change to enterprise architecture by 2023. Cloud computing will have the ability to bring enterprise architecture a step forward and redefine the way businesses will support their architecture. As cloud computing evolves, as will enterprise architecture in the way that advanced concepts and practices will eventually be deemed as government requirements. By 2023, I anticipate that most, if not all, companies will be using a cloud platform where it will be used on multiple devices – this brings attention to EA as it will make it more challenging to standardized personal devices. BYOD will become a more relevant option with increased capabilities, like scalability and using software as a service through the cloud, impacting the way EA is integrated in an organization. The shift in enterprise architecture will also stem from the control needed from cloud computing. Currently, when companies move to cloud computing, they are essentially handing control over the design parameters of the enterprise. As a result, the role of the enterprise architect will become obsolete as the responsibilities were to build and maintain a stable model for the business. The...

...Last Friday, I attended the Social Enterprise Symposium hosted by the REDACTED. At the symposium, I attended “Reinventing the Economy: Value Creation & Capital Markets” as well as another event titled “Three Business Models for Social Impact.” While the first event focused on generating capital to fund social enterprises, the latter centered on new business models that attempt to drive social change. At the first event, “Value Creation and Capital Markets,” speakers discussed how socially responsible companies can still use traditional methods of financing. In particular, they tried to push five major points. These points were external options of financing, internal options of financing, crowd funding, appropriate sources for capital, and new financial mechanisms. Of the five, external financing is by far the most traditional method of financing. It includes equity, banks/credit unions, friends/family, and social investors. Social investors can be particularly helpful because they are typically the most interested in your cause. Additionally, philanthropic grants can be used, but often not a reliable means of funding. Government funding is more reliable, but requires more extensive obligations. Internal options can be another source of funding. For example, a company can collect accounts receivable as quickly as possible by offering discounts for timely payment or interest for late payment. On the other hand, they can also delay making payments on accounts payable...

...18, 2014 Putting the Enterprise into the Enterprise System Article Summary Jason Simonds Enterprise systems can be an effective tool for a business; they can enable a company to integrate data puled from several different functions in an organization and allow for more efficient communication between separate systems. Business enterprises can connect shipping to sales and sales to accounting and accounting to finance all under one digital roof. The article Putting the Enterprise into the Enterprise System elaborates on the benefits such systems can have on a company, but highlights some of the problems a poorly fitting system can cause and how these problems can be avoided. While enterprise systems can greatly help a business, a poorly designed system can be costly and timely to fix. A company with multiple departments and different functions can have hundreds of different tasks that are maintained in a system. Between shipping, receiving, design, accounting, etc. each function has a separate design and multiple tasks to complete. These tasks and designs are often performed on separate systems within an organization. The shipping department may have a program designed for commercial shipping which may not integrate with the accounting software used by the accounting department or the inventory software kept within the warehouse. These “legacy” systems can often be tedious and expensive to work with and can slow a business down. Enterprise systems can fully integrate...

...Summary of Enterprise Architecture An Enterprise Architecture (EA) is a design or a conceptual blueprint of a business that defines the structure and operation of an organization. The purpose of an enterprise architecture is to depict the interrelationships of all components and the information flow. It shows how each component supports the objectives and strategies of an enterprise. To achieve an overall view and to depict all those components and information flow, it is necessary to apply some architecture principles and practices to guide organization through the business, information, process and technology changes. These practices utilize the various aspects of an enterprise to identify, motivate and achieve these things. The business practice and perspective defines the processes and standards by which the business operates on a day-to-day basis. The information practice and perspective defines and classifies raw data that the organization requires to operate efficiently. Such raw data could be document files, databases, images, diagrams, presentations and spreadsheets among many more things. Another practice and perspective is the process that defines how the processes interact and what standards are used to do so. The last practice and perspective is to look at the technology that defines what kind of hardware, operating systems, programming and networking is used by the organization. By establishing a powerful enterprise architecture there are of purported advantages...

...The Contribution of Enterprise Systems An enterprise system is classified as a system of integrated application-software packages that use data storage and transmission to support the flow of information, reporting, and analytics in the company as well as in some cases it is used outside of the company by colleagues and clients. Enterprise systems manage the flow of information relevant to those within the company as well as those outside of the company that have permission to access certain information. If a company has multiple lines of products and information that is relevant to all products such as statistical data that needs to be shared with all people within the company, an enterprise system exists to enable the sharing of information. An enterprise system provides as single system central to the organization which ensures that the information can be shared across all management and functional levels Enterprise systems are also invaluable with elimination of problems with information fragmentation which can be caused by having multiple information systems in an organization. It does this by creating a standard data structure. Typical information systems are housed in data centers and would run enterprise software as well as include application such as; content management systems that would cross organizational borders. Enterprise systems provide value for increasing operational efficiency, as well as provide wide information to help managers make informed and effective...
