    Evolution of a Software Maintenance Organization from Cost Center to Service Center

    Get PDF
    The paper describes experiences with the evolution of a software maintenance organization for digital set-top boxes of a leading electronics company from a cost center towards a service center. Several years ago a dedicated software maintenance group was constituted. As the costs for software maintenance were not recovered from the customers, the software maintenance group was merely considered a cost center. Through starting a metrics program for software maintenance and defining a service strategy with various service levels, the software maintenance group generated sufficient revenues to become self-supporting. An important conclusion is that the use of ITIL (IT infrastructure library) service support has helped to develop a better customer focused approach, which is considered as the most important critical success factor for a professional, self-supporting maintenance organization

    The United State's big space projects of the next decades, such as Space Station and the Human Exploration Initiative, will need the development of many millions of lines of mission critical software. NASA-Johnson (JSC) is identifying and developing some of the Computer Aided Software Engineering (CASE) technology that NASA will need to build these future software systems. The goal is to improve the quality and the productivity of large software development projects. New trends are outlined in CASE technology and how the Software Technology Branch (STB) at JSC is endeavoring to provide some of these CASE solutions for NASA is described. Key software technology components include knowledge-based systems, software reusability, user interface technology, reengineering environments, management systems for the software development process, software cost models, repository technology, and open, integrated CASE environment frameworks. The paper presents the status and long-term expectations for CASE products. The STB's Reengineering Application Project (REAP), Advanced Software Development Workstation (ASDW) project, and software development cost model (COSTMODL) project are then discussed. Some of the general difficulties of technology transfer are introduced, and a process developed by STB for CASE technology insertion is described

    Web development evolution: the business perspective on security

    Get PDF
    Protection of data, information, and knowledge is a hot topic in today’s business environment. Societal, legislative and consumer pressures are forcing companies to examine business strategies, modify processes and acknowledge security to accept and defend accountability. Research indicates that a significant portion of the financial losses is due to straight forward software design errors. Security should be addressed throughout the application development process via an independent methodology containing customizable components. The methodology is designed to integrate with an organization’s existing software development processes while providing structure to implement secure applications, helping companies mitigate hard and soft costs

    Advancing automation and robotics technology for the space station and for the US economy: Submitted to the United States Congress October 1, 1987

    Get PDF
    In April 1985, as required by Public Law 98-371, the NASA Advanced Technology Advisory Committee (ATAC) reported to Congress the results of its studies on advanced automation and robotics technology for use on the space station. This material was documented in the initial report (NASA Technical Memorandum 87566). A further requirement of the Law was that ATAC follow NASA's progress in this area and report to Congress semiannually. This report is the fifth in a series of progress updates and covers the period between 16 May 1987 and 30 September 1987. NASA has accepted the basic recommendations of ATAC for its space station efforts. ATAC and NASA agree that the mandate of Congress is that an advanced automation and robotics technology be built to support an evolutionary space station program and serve as a highly visible stimulator affecting the long-term U.S. economy

    HR Shared Services (HRSS): Model and Trends

    Get PDF
    [Excerpt] The findings of this research project are based on interviews with 44 Human Resources (HR) leaders across 39 national and international companies within 15 industries ranging from manufacturing to consulting services. The interviews ranged from 45 minutes to one hour, and sought to understand models, best practices, and trends. The interview included questions about employee experience, technology, and the integration between HR Shared Services (HRSS) and the overall HR Organization. To provide background information and data, the HR leaders answered a short survey, giving details about the structure of their HRSS, locations, areas of HR that had work performed in the shared services organization, systems, and technology capabilities

    Integrated controls and health monitoring for chemical transfer propulsion

    Get PDF
    NASA is reviewing various propulsion technologies for exploring space. The requirements are examined for one enabling propulsion technology: Integrated Controls and Health Monitoring (ICHM) for Chemical Transfer Propulsion (CTP). Functional requirements for a CTP-ICHM system are proposed from tentative mission scenarios, vehicle configurations, CTP specifications, and technical feasibility. These CTP-ICHM requirements go beyond traditional reliable operation and emergency shutoff control to include: (1) enhanced mission flexibility; (2) continuously variable throttling; (3) tank-head start control; (4) automated prestart and post-shutoff engine check; (5) monitoring of space exposure degradation; and (6) product evolution flexibility. Technology development plans are also discussed
