An evaluation framework for deploying Web Services in the next generation manufacturing enterprise

In today's competitive manufacturing environment, the ability to effectively and efficiently manage the flow of information is a vital competency. Manufacturing enterprises must be able to integrate their internal business processes horizontally and vertically, and they are increasingly required to support federated business processes with other members of their respective virtual value chains. Web Services, an emerging form of service-oriented architecture for distributed computing, have the potential to serve as a key enabling technology to support these requirements. Leveraging the inherent interoperability of Internet and Worldwide Web technologies, they enable cooperative processing across heterogeneous computing environments. This paper presents a framework for evaluating the viability of Web Services technologies to be incorporated into enterprise information architectures to support the business needs and requirements of next generation manufacturing enterprises. It examines economic, technical, and organizational contexts that will influence the ability of manufacturing-related enterprises to deploy advanced information architectures based on Web Services to support the complex business processes needed to collaborate with suppliers, customers, and other stakeholders in virtual enterprise environments.

Countering the “dam effect”: the case for architecture and governance in developing country health information systems

ABSTRACT

This paper presents a case for enterprise architecture (EA) and IT governance for driving techno-organizational change and coordination of health information systems (HISs) in developing countries. We support our claim with analyses of a large-scale electronic HIS in Ethiopia by tracing the logic of actors’ decisions and conduct within and beyond the organizational boundaries of the Ethiopian Federal Ministry of Health to understand how the information system innovation process is designed, legitimized and imposed by internal and external organizational forces. In the absence of formalized institutional arrangements throughout the HIS development and implementation, an international development agency fills a key gap forming an obligatory passage point which we conceptualize as “the dam effect.” Drawing on actor-network theory, we identify three important implications of EA and IT governance: (1) to help achieve an alignment of interests within the enterprise; (2) to serve as a tool for protecting the interests of the enterprise in external negotiations; and (3) to serve as a pragmatic approach to carrying out techno-organizational change.     

Research and Development on Manufacturing Enterprise Integration Framework

Currently many enterprises have established some independent application systems such as CAD, CAPP, CAE and so on. Enterprise information integration makes these information islands connected, and thereby forms a uniform enterprise-wide information environment. First this paper discusses the main research contents of enterprise integration. Then the author introduces an Internet-based configurable and open information integration framework, and presents a multi-tier integration architecture based on reusable component. Finally a development case of enterprise integration framework is introduced.

Knowledge transfer,translation and transformation in the work of information technology architects

ContextInformation Technology (IT) architects are the professionals responsible for designing the information systems for an organization. In order to do that, they take into account many aspects and stakeholders, including customers, software developers, the organization’s business, and its current IT infrastructure. Therefore, different aspects influence their work.ObjectiveThis paper presents results of research into how IT architects perform their work in practice and how different aspects are taken into account when an information system is developed. An understanding of IT architects’ activities allows us to better support their work. This paper extends our own previous work (Figueiredo et al., 2012) [30] by discussing aspects of knowledge management and tool support.MethodA qualitative study was conducted using semi-structured interviews for data collection and grounded theory methods (Strauss and Corbin, 1998) [5] for data analysis. Twenty-seven interviews were conducted with twenty-two interviewees from nine different companies through four cycles of data collection and analysis.ResultsCompanies divide IT architecture activities among different roles. Although these roles receive different names in different organizations, all organizations follow a similar pattern based on 3 roles: enterprise, solutions and software architects. These architects perform both the technical activities related to the IT architecture and the social activities regarding the communication and coordination with other stakeholders and among themselves. Furthermore, current tools used by IT architects lack adequate support for all these aspects.ConclusionThe activities of the different IT architects are highly interconnected and have a huge influence in the way the requirements are handled in every phase of the development of an information system. The activities of IT architects are also important for knowledge transfer, translation and transformation, since they receive from and spread information to different groups of stakeholders. We also conclude that they lack appropriate tool support, especially regarding support for their collaborative work.

Composing enterprise mashup components and services using architecture integration patterns

Enterprise mashups leverage various source of information to compose new situational applications. The architecture of such applications must address integration issues: it needs to deal with heterogeneous local and/or public data sources, and build value-added applications on existing corporate IT systems. In this paper, we leverage enterprise architecture integration patterns to compose reusable mashup components. We present a service oriented architecture that addresses reusability and integration needs for building enterprise mashup applications. Key techniques to customize this architecture are developed for mashups with themed data on location maps. The usage of this architecture is illustrated by a property valuation application derived from a real-world scenario. We demonstrate and discuss how this state-of-the-art architecture design method can be applied to enhance the design and development of emerging enterprise mashups.
