Web-based Supply Chain Management

A key constituent of supply chain management strategies is information sharing. Software component technology facilitates information sharing by providing a means for integrating heterogeneous information systems into virtual information systems. Extranet technology facilitates information sharing between an enterprise and its business partners as well as its customers through the Internet. These two technologies enable new strategies that integrate information systems and improve supply chain networks. We discuss the application of these strategies to supply chain processes.     

Dominant actors, political agendas, and strategic shifts over time: a critical ethnography of an enterprise systems implementation

Much of the literature on enterprise systems implementation suggests that ERP systems should support the strategic objectives of the organization. In fact some ERP vendors tend to assume that implementing their products is a straightforward translation from strategy to IT-enabled business processes. But the strategic management literature reveals that corporate strategy is often contested terrain. Conflict over strategy has the potential to delay or derail ERP implementation efforts, leading to cost overruns, failures, and lack of expected benefits.This paper seeks to understand and explain how conflicts over strategy can affect the success of ERP implementations. We studied one firm's attempt to pursue information technology-enabled enterprise integration using critical ethnography. The firm is a small-to-medium sized enterprise within a large conglomerate in the Asia-Pacific region. Our findings show that, as the dominant actors and political agendas changed, so too did the company's enterprise integration strategy. The ERP system was designed to support a future corporate world and work environment that never arrived.     

Effects of Adoption and Assimilation of Enterprise Systems on Business Performance: A Senior Executive’s Perspective

Drawing from the institutional theory and resource-based view, we investigated the effects of a firm’s activities and levels of enterprise systems adoption and the effectiveness of the enterprise systems in supporting the firm (enterprise systems assimilation) on business performance. Empirical results suggest that institutional forces and IS resources significantly influence the enterprise systems adoption, which indirectly impacts the enterprise systems assimilation. Further, the enterprise systems adoption significantly influences business performance, and the enterprise systems assimilation mediates the effect of the enterprise systems adoption on business performance.     

Information management in process-based organizations: a case study at Xerox Ltd

Abstract. The process-oriented holistic enterprise is a new organizational form in which the business process may be perceived as the basic organizational construct. Process management on an enterprise-wide scale implies a complex integration of business processes. The increased organizational complexity places heavy demands on a firm's information management capability, and this needs to be managed in a way that best supports the process model. This research has found that in the case of Xerox Ltd, a company that has adopted a holistic approach to process management, the information management process is key to supporting this method of organizing. The main finding is that, in order to support process management, a particular type of information management is required. This includes a need for enterprise-wide information systems and the centralization of systems development and maintenance. However, the process management is made possible by this type of information management. This may be referred to as the duality concept of information and process management. The research presents findings from an in-depth participant observation study conducted at the Xerox Ltd headquarters in the UK, and also includes data collected from Xerox France and Xerox UK.     

Building an E-Business from Enterprise Systems

Building their companies into successful e-businesses has become an important objective for today's enterprises. Conceptually, it embodies the enabling of the business with such capabilities as global networking, streamlining business processes, sharing information, agility in responding to the market, and intelligent decision making. But how can these concepts be implemented in actual enterprises? Why do these desirable attributes of business systems suddenly become the definition of competency of companies large and small? This paper describes the framework for building an e-business from the enterprise information systems' perspective. Increasingly enterprise systems have extended beyond the traditional business functions and include such new features as supply-chain management, customer relationship management and electronic commerce. The shifting focus is driven by the adoption of the Web as a new channel for product distribution, marketing, and interacting with customers. The integration of the traditional as well as the Web-oriented functions is the cornerstone for a successful e-business. This paper presents a framework for e-businesses that on one hand build on the enterprise systems but on the other hand encompasses the new e-business dimensions.     

Towards a flexible deployment of business rules

Business rules give rise to an important set of requirements on any system being developed or procured for an enterprise. While most of the work done in this area focuses on identifying and documenting business rules, we have proposed a methodology that addresses several aspects of the business rules lifecycle: acquisition, deployment and evolution. The methodology assumes that business rules are expressed in terms of business concepts and corporate knowledge that are captured in a high level architecture. The architecture proposed consists of three interconnected components: the enterprise model, the business rules model and the decision support model. This approach permits a greater variety of rules to be specified while providing an opportunity to automate the production of deployable business rules. The ability to deal with the inconsistent and ambiguous rules is crucial in capturing the conflicting requirements placed on the operation of any large scale enterprise. This paper presents a flexible deployment of business rules, which not only supports decision making in the face of conflicting requirements, but also the evolution of those requirements in the face of changing regulatory environments, competitive markets and corporate goals.

Business Analytics-Based Enterprise Information Systems

Big data analytics and business analytics are a disruptive technology and innovative solution for enterprise development. However, what is the relationship between business analytics, big data analytics, and enterprise information systems (EIS)? How can business analytics enhance the development of EIS? How can analytics be incorporated into EIS? These are still big issues. This article addresses these three issues by proposing ontology of business analytics, presenting an analytics service-oriented architecture (ASOA) and applying ASOA to EIS, where our surveyed data analysis showed that the proposed ASOA is viable for developing EIS. This article then examines incorporation of business analytics into EIS through proposing a model for business analytics service-based EIS, or ASEIS for short. The proposed approach in this article might facilitate the research and development of EIS, business analytics, big data analytics, and business intelligence.     

Using Markets to Engineer Resource Management for the Information Grid

Information systems are continually expanding as evidenced by the doubling of Internet connections every year. Similar growth is exhibited by information systems in defense. The Air Force's goals to achieve global awareness, dynamic planning/execution, and global information exchange involve the technologies to provide information to the warrior anywhere, anytime, and for any mission. This far-reaching enterprise will necessarily span multiple networks and computing domains of both the commercial and military varieties. As a result, many users with different goals and priorities vie for the communication and computing resources of the information grid. Managing this vast system to assure dependable operation that maintains users' quality of service levels has led researchers to propose economic models to solve the resource management problem. Information technology has begun to fundamentally alter the way business is conducted, and there is synergy between e-commerce and the management of the underlying information resources on which it runs.This paper examines the envisioned market-based, large-scale information systems for defense. Due to their criticality, these systems must also manage resources to provide survivability in the presence of information attacks. This potential for technology transfer from the defense sector to the commercial sector are described. Conversely, the leveraging of research performed in the non-military realm of e-commerce to reach the Air Force's goals will also be explored.

An industrial case study on variability handling in large enterprise software systems

ContextEnterprise software systems (e.g., enterprise resource planning software) are often deployed in different contexts (e.g., different organizations or different business units or branches of one organization). However, even though organizations, business units or branches have the same or similar business goals, they may differ in how they achieve these goals. Thus, many enterprise software systems are subject to variability and adapted depending on the context in which they are used.ObjectiveOur goal is to provide a snapshot of variability in large scale enterprise software systems. We aim at understanding the types of variability that occur in large industrial enterprise software systems. Furthermore, we aim at identifying how variability is handled in such systems.MethodWe performed an exploratory case study in two large software organizations, involving two large enterprise software systems. Data were collected through interviews and document analysis. Data were analyzed following a grounded theory approach.ResultsWe identified seven types of variability (e.g., functionality, infrastructure) and eight mechanisms to handle variability (e.g., add-ons, code switches).ConclusionsWe provide generic types for classifying variability in enterprise software systems, and reusable mechanisms for handling such variability. Some variability types and handling mechanisms for enterprise software systems found in the real world extend existing concepts and theories. Others confirm findings from previous research literature on variability in software in general and are therefore not specific to enterprise software systems. Our findings also offer a theoretical foundation for describing variability handling in practice. Future work needs to provide more evaluations of the theoretical foundations, and refine variability handling mechanisms into more detailed practices.
