  • Topic: User-centric Enterprise Architecture
    Margaret Sarro
    Office of Enterprise Architecture and IT Governance, the United States Coast Guard
    Abstract:
    When presenting EA information, practitioners often rely on esoteric EA "artifacts" that are too complex for executives to use when making decisions. This presentation presents the "User-centric EA Methodology" as a solution to this problem. Based on best practices from industry and government, user-centric EA focuses on developing useful and useable information products and governance for the end-user. In user-centric EA, information is relevant, easy to understand and readily accessible. The presentation will draw on practical examples from the U.S. Coast Guard to show user-centric EA in action.

  • Topic 1: Coherent EA and Segment Architecture
    John Wu, Senior Architect, Dept of Labor
    Abstract:
    Enterprise Architecture (EA) has been evolving in many different directions. This presentation suggests a Coherent EA approach to balance various business architecture centric, system architecture centric and technology centric EA approaches. Working toward a composite direction and implement EA via segment architecture, EA is the coherent team effort of business architecture to know the enterprise; system architecture to align IT solutions; and the cross-cutting effort to enable the agility to provide EA value in time of business need and mange the continuous change in the enterprise. The coherent EA approach introduces the agility dimension to deliver result in time of need and the capability to manage the continuous change of enterprise with following definition:

    Agility is the key to win the competitive edge of the competitive world. An Enterprise, unlike a building architecture which follows a blueprint, is not static. Most of Enterprise has encountered challenges beyond their original plan.

    Coherent EA is implemented incrementally via Segment Architecture in the following steps.

    • Initial EA effort to conduct Enterprise modeling and system architecture at the high level;
    • Establish common standards, common foundation and building blocks by learning experiences from the same line of business identified from the high level Enterprise model to enable agility;
    • Close business performance gaps via segment architecture which elaborate the high level business modeling and solution architecture.

    Topic 2: The Viable System Model: a Guide for Enterprise Architecture
    Stuart A. Umpleby, Ph.D., Department of Management, The George Washington University, Washington, DC 20052
    Abstract:
    The Viable System Model (VSM) was described by British cybernetician Stafford Beer in his books Brain of the Firm (1972), The Heart of Enterprise (1979), and Diagnosing the System for Organizations (1985). The VSM is a model of organizational structure and functioning that is based on the human nervous system. Beer notes that the human nervous system as a device for information processing and decision-making is the result of millions of years of evolution. Imitating it may have some advantages. The Viable System Model is based on Ross Ashby's theory of adaptive behavior and his Law of Requisite Variety. The VSM has been used primarily as a means for diagnosing problems in organizations. Perhaps it would also be useful to enterprise architects.

  • A Competency Framework for the DoD Architect
    by Walter Okon, Chief Architect, DoD Information Sharing, Dept of Defense
    Abstract:
    This Briefing and White Paper proposes a way ahead for developing a more effective architecture workforce. It recommends investigating the need for a framework that captures the knowledge, skills, abilities, and functions an architect in the DoD is expected to exhibit. The purpose of such a framework would be to promote the development of the current and future DoD architecture workforce against a set of standards through career development, education, training, and certification as appropriate. Setting standards would legitimize the DoD architect role for all initiatives and across all career paths. An initial competency framework capturing the information obtained from contributors is presented in this paper to provide a starting point for further analysis. This White Paper was prepared by the Office of the DoD Chief Information Officer (CIO)/Architecture and Interoperability (A&I) Directorate in coordination with the CIO Management Services Directorate and is based on input provided by participants of the DoD Architecture Training Workshops.

  • Topic 1: Recognizing and Managing Cultural Patterns
    by Dr. Stuart Umpleby, Department of Management, The George Washington University
    Abstract: Introducing and managing changes to enterprises often encounter cultural misunderstandings and obstacles. It is, however, possible to turn culture from a negative factor into a positive or at least a neutral factor for changes. Managing the cultural factor requires recognizing cultural patterns and identifying possible management approaches toward different cultural patterns. This paper describes the most well-known and accepted theories of cultural differences and illustrates them with examples from international project management. These theories consider relations between people, motivational orientation, orientation toward risk, definition of self and others, attitudes toward time, and attitudes toward the environment. The paper concludes that change management can succeed through culturally-aware leadership, effective cross-cultural communication, mutual respect and reconciliation.

  • Topic 2: Architectural Design Strategies and Tools for Achieving Improved Performance in Public Service Organizations
    by Samuel T. Harmon
    Abstract: This presentation offers an architectural-design approach to the continuous improvement of the performance of public service agencies. The approach is based on a model that is useful for identifying and balancing the functional needs of external beneficiaries (both people and organizations) with the policies and resource constraints of the host agency. With this approach, the architect can design features that strengthen managerial control and allow the organization to adapt effectively to a changing environment. Continuous performance improvement projects for most government agencies are complex and of varying length. This approach suggests meeting short, medium and long-term goals with a program of projects supported by computerized sets of graphical analysis and design tools. The talk concludes with an example of an application of tools to a possible project having military veterans the target beneficiaries.

  • Integrating Security within Enterprise Architecture (PPT) (518KB)
    by Dan Ford, Senior Security Architect, BAE Systems Information Technology
    Abstract: Enterprise Architecture Security functions as a set of building blocks that connect the business of an organization with its security program. The foundation starts with ensuring that that the organization has policies, procedures, processes, and personnel in place to formulate the strategic vision of the security program for the organization. By integrating Security within the Enterprise Architecture, it will assist an organization's efforts in planning for future funding requirements related to the Security and Privacy requirements of its information systems.

  • An Overview of ISO Standards Pertinent to Enterprise Architecture (PDF) (1 MB)
    by Richard Martin, Convener of ISO TC184/SC5/WG1 on Architecture, Communications, and Integration Frameworks
    Abstract: Under the auspices of the ISO, Working Group 1 (WG1) of TC184/SC5 has published a set of international standards that specify rules, requirements, framework, and modeling constructs for use in developing enterprise architectures and models for complex intelligent systems of systems applications. This presentation will focus on the first two of a set of four: ISO 14258:1998 Concepts and rules for enterprise models, which provides a foundation for system architecture; ISO 15704:2000 Requirements for enterprise-reference architectures and methodologies, which establishes an architectural and model-based reference; ISO 19439:2006 Framework for enterprise modeling, which articulates a unified approach for enterprise models; and, ISO/FDIS 19440 Enterprise integration - Constructs for enterprise modeling, which provides a set of modeling elements for the unified framework.
