EWSolutions, Inc. 1/25/2017 Developing and Implementing a New Defense Logistics Supply Chain: A Case Study in How EWSolutions Enabled Success for the US Department of Defense The Department of Defense (DoD) is America's oldest and largest government agency. It employs a civilian force of 742,000, along with over 1.3 million men and women on active duty; it is the United State's largest employer. Another 826,000 people serve in the National Guard and Reserve forces. The national security depends on defense installations, people, and facilities being in the right place, at the right time, with the right qualities and capacities to protect the security of the United States and allies. These military service members and civilians operate in every time zone and in every climate. More than 450,000 employees are overseas, both afloat and ashore. This complexity extends to the logistics, communication, and supply chain needed to connect and furnish these employees and dependents with all the required resources (food, clothing, weapons, etc.) The mission of the US Department of Defense is to provide the military forces needed to deter war and to protect the security of the United States. Fulfilling this mission requires a large variety of resources; securing and delivering those resources to the right place at the right time in the right quantities requires accurate information that comes from complete and valid data.

    Enterprise Architecture Dr. Adnan Albar Faculty of Computing & Information Technology King AbdulAziz University - Jeddah 1 Enterprise Architecture Methods Lecture 5 Week 5 Slides King AbdulAziz University - FCIT 2 Overview . Description Languages for Business & IT Domains . IDEF . BPMN . Testbed . ARIS . Unified Modeling Language . Service-Oriented Architecture (SOA) Slide 3 Description Languages . In domains such as business process design and software development, we find established description languages for modeling these domains. For software modeling, UML is of course, the single dominant language. In organization and process modeling, on the other hand, a multitude of languages are in use: there is no standard for models in this domain. We will focus on languages that either find widespread use or have properties that are interesting from the perspective of our goals in developing an enterprise architecture language. Slide 4 IDEF – Integrated DEFinition Methods .IDEF is a family of languages .Used to perform enterprise modeling and analysis .Currently, there are 16 IDEF methods. Of these methods, IDEF0, IDEF3, and IDEF1X (‘the core’) are the most commonly used. Slide 5 IDEF – The Scope it Covers .Functional modeling, IDEF0: The idea behind IDEF0 is to model the elements controlling the execution of a function, the actors performing the function, the objects or data consumed and produced by the function, and the relationships between business functions (shared resources and dependencies). .Process modeling, IDEF3: IDEF3 captures the workflow of a business process via process flow diagrams. These show the task sequence for processes performed by the organization, the decision logic, describe different scenarios for performing the same business functions, and enable the analysis and improvement of the workflow.

  • Integrating IT Portfolio Management with Enterprise Architecture Management 79
    Enterprise Modelling and Information Systems Architectures Vol. 8, No. 2, December 2013 Integrating IT Portfolio Management with Enterprise Architecture Management 79 Daniel Simon, Kai Fischbach, Detlef Schoder Integrating IT Portfolio Management with Enterprise Architecture Management The management of information technology (IT) as a business has become a crucial factor in today’s complex and dynamic environments. Many firms thus have implemented IT portfolio and enterprise architecture (EA) management practices, and academic research has paid increasing attention to these concepts. However, their integration seems poorly substantiated; this article therefore seeks to answer two main questions: (1) What are differences and common characteristics of IT portfolio and EA management, and in what way can they be integrated? and (2) what factors and types might describe an integrated process design of EA management and project portfolio management in particular? To answer these questions, this study synthesises previous research and surveys EA practitioners to propose an EA management process map, as well as three descriptive factors and four clusters, which provide an integrated process design with project portfolio management. The interrelations with organisational aspects and software tool support are also explored. This article thereby clarifies and systematises the subject area while also offering advice for researchers and practitioners. 1 Introduction structured, business-like approach to IT manage- ment that comprises application, infrastructure, The notion of managing information technology service, and project portfolio management (Ben- (IT) as a business (Lientz and Larssen 2004) has son et al. 2004; Kaplan 2005). attracted significant attention, particularly as IT environments grow steadily more complex and Integration is equally critical to EA management, thus more difficult to manage.

  • ERP Application Lifecycle Management (ALM): 10 Reasons Why ERP Change Management Has Outgrown Helpdesk Software
    E NTERPRISE C HANGE M ANAGEMENT ERP Application Lifecycle Management (ALM): 10 reasons why ERP change management has outgrown helpdesk software. Advances in ERP applications combined with complex implementations are challenging ERP specialists to manage change faster with fewer errors. As business-driven changes come faster, many ERP managers are struggling to break the ROI barrier for their ERP applications. Helpdesk-centric CM strategies do little to address the needs of complex ERP support and upgrade tasks, and increase the organization’s exposure to unmanaged and unauthorized ERP changes. Now, process-based CM/ALM capabilities are providing the ability to bridge an ERP from the implementation project to Level 2 production support with much less risk, while reducing ERP ownership costs (TCO). Introduction ERP Applications are driving Enterprise Architecture Change Companies using Enterprise Resource Planning (ERP) applications are making large investments in the future. It is said that implementing an ERP application The best Enterprise can be compared to “re-wiring the Enterprise Central Nervous System”.
