    The article describes the process of estimating the cost and complexity of software development for the task of inventory management of a commercial enterprise to improve the decision-making process at the stage of formation of requirements for similar software products. There are different approaches to inventory management of a commercial enterprise. The algorithms implemented in the system are based on the constraint theory tool –dynamic inventory buffer management. Inventory management according to the theory of restrictions allows to provide a high level of availability of goods with minimal inventory in the system. After analyzing the subject area of inventory management and the methodology of dynamic inventory buffer management, a list of functional and non-functional software requirements was formed, and a data model was designed. The information obtained was used to compile a list of logical files and transactions specific to a particular requirement. From the resulting list of files and transactions, it is determined which elementary data, elementary records and links to files they consist of. The information obtained was used to estimate the size of the software at non-aligned functional points. To take into account the impact of non-functional requirements on the complexity of software development, the VAF alignment factor was calculated, for which it is necessary to give a qualitative assessment of the impact of system-wide requirements on the complexity of the software. The estimation of the complexity of the development was obtained using the COCOMO II methodology, namely, using seven multipliers of the complexity for the case of the initial assessment at the stage of approval of requirements. The calculations were obtained for teams with different professional level and equipment, in the conditions of a significant tightening of the development process, a high level of certainty of risks, without a rigid schedule of work. The cost of development was calculated for several common programming languages: J2EE, C#, C++.В статье описывается процесс оценки стоимости и трудоемкости разработки программного обеспечения задачи управления запасами торгового предприятия для улучшения процесса принятия решений на этапе формирования требований к аналогичным программным продуктам. Существуют различные подходы к управлению запасами торгового предприятия. Алгоритмы, реализованные в системе основаны на инструменте теории ограничений – динамическом управлении буфером запасов. Управление запасами по теории ограничений позволяет обеспечить высокий уровень наличия товара при минимальных запасах в системе. Проанализировав предметную область управления запасами и методологию динамического управления буфером товарных запасов был сформирован список функциональных и нефункциональных требований к программного обеспечения, а также спроектирована модель данных. Полученная информация была использована для составления перечня логических файлов и транзакций, характерных для конкретного требования. Из полученного списка файлов и транзакций определено, из каких элементарных данных, элементарных записей и ссылок на файлы они состоят. Полученная информация была использована для оценки размера программного обеспечения в не выровненных функциональных точках. Для учета влияния нефункциональных требований на трудоемкость разработки программного обеспечения был посчитан фактор выравнивания VAF, для чего необходимо дать качественную оценку влияния общесистемных требований на трудоемкость программного обеспечения. Оценка трудоемкости разработки была получена с использованием методологии COCOMO II, а именно с использованием семи множителей трудоемкости для случая первичной оценки на этапе утверждения требований. Расчеты были получены для команд с разным профессиональным уровнем и оборудованием, в условиях значительного ужесточения процесса разработки, высоким уровнем определенности рисков, без жесткого графика работ. Стоимость разработки была рассчитана для нескольких распространенных языков программирования: J2EE, C#, C++

    The Dynamic of Assets and Liabilities of Foreignness

    Researchers have recognized that foreign firms possess both advantages and costs in operating in host countries. The extant literature suggests that the liability of foreignness can be gradually overcome as a foreign subsidiary learns more about the host country environment and develops better connections to local business networks. Based on a longitudinal case study of the Chinese management software industry, however, we find that even over the long term foreign firms continue to face difficulties in accessing some important potential country-specific advantages to overcome liability of foreignness. We develop a framework to explain why and how local firms more successfully access country-specific advantages at home because of their local complementary knowledge, local relationships, and home-focused strategies and understand the dynamic of assets and liability of foreignness. These findings have important implications for the persistence of liability of foreignness and for established MNEs wishing to compete in emerging markets as well as helping to explain the emergence of strong competition from local firms in emerging economies

    This is a teaching case on a real life scenario in an organization involving IT solution evaluation and selection. This case involves the Bank of America’s Foreign Items Systems office in Toronto. The officers from the Bank of America’s Foreign Items Systems office in Toronto were discussing how to respond to a Request for Proposal (RFP) from a major U.S. bank to provide foreign currency services. The case discusses three options: Standard J2EE Web Application Global Foreign Currency, Modified J2EE Web Application with Single Sign On, and Service-Oriented Architecture (SOA) via Web Services. The case can be used to complement chapters in MIS and IT courses that are related to Systems Integration, IT Infrastructure or IT Implementation. The case can also be used to discuss IT planning, management, evaluation, and trade-off issues. The case is intended for use by senior undergraduate and MBA students

    Investigating the Feasibility of Open Development of Operations Support Solutions

    No full text
    The telecommunications Operations Support Systems supply chain must address many stakeholders: R&D, Product and Requirements Management, Purchasing, Systems Integration, Systems Administration and Users. While the management of next generation networks and services poses significant technical challenges, the present supply chain, market configuration, and business practices of the OSS community are an obstacle to rapid innovation. Forums for open development could potentially provide a medium to shorten this supply chain for the deployment of workable systems. This paper discusses the potential benefits and barriers to the open development of OSS for the telecommunications industry. It proposes the use of action research to execute a feasibility study into the open development of OSS software solutions within an industry wide Open OSS project
