Investigating success factors in enterprise application integration: a case-driven analysis

This paper investigates Critical Success Factors (CSFs) in Enterprise Application Integration (EAI). An initial set of CSFs for EAI projects was created based on a review and synthesis of the literature in the general area of integration, including Enterprise Resource Planning (ERP) projects. A case analysis, involving a large financial services provider integrating its consumer banking systems, was used to validate the CSFs. The findings resulted in a more structured and holistic CSF model which identifies three broad groups of CSFs, namely (1) top management support, (2) overall integration strategy, and (3) EAI project planning and execution. Although EAI projects share many of the same CSFs as ERP projects and other information systems projects, issues related to the selection of the right EAI tool and emphasis on technology planning and enterprise architecture are distinguishing features of EAI projects. Some of practical implications of the research are that EAI projects require personnel with specific skills and expertise, business integration should precede technology integration, that availability of adapters is an important criteria in EAI tool selection and that some custom adapter development may be unavoidable if custom applications need to be integrated.

An integrated decision making approach for ERP system selection

Enterprise resource planning (ERP) systems have gained major prominence by enabling companies to streamline their operations, leverage and integrate business data process. In order to implement an ERP project successfully, it is necessary to select an ERP system which can be aligned with the needs of the company. Thus, a robust decision making approach for ERP software selection requires both company needs and characteristics of the ERP system and their interactions to be taken into account. This paper develops a novel decision framework for ERP software selection based on quality function deployment (QFD), fuzzy linear regression and zero–one goal programming. The proposed framework enables both company demands and ERP system characteristics to be considered, and provides the means for incorporating not only the relationships between company demands and ERP system characteristics but also the interactions between ERP system characteristics through adopting the QFD principles. The presented methodology appears as a sound investment decision making tool for ERP systems as well as other information systems. The potential use of the proposed decision framework is illustrated through an application.     

信息集成关键技术——企业服务总线

Commodity or competitive advantage? Analysis of the ERP value paradox

A true e-business enabled firm needs the support from a well-tuned enterprise resource planning (ERP) system for providing real time data. However, many companies complain that after their huge investments in ERP systems, they found the ERP systems do not bring them new orders, new profits, or competitive advantage as ERP vendors claim. Academic studies also found mixed results regarding ERP’s payoff. In line with resource based view (RBV), the study proposes an integrated model to shed light on the ERP value paradox. We try to answer “With what organizational resources and by building what firm specific capabilities, the investment in ERP systems may bring firms competitive advantage”. Using a sample of 150 ERP and e-business adopters in the US, we found that (1) organizational resources such as managerial skills and organizational change management play a more important role than IT resources (ERP, e-Business technologies) in generating business integration capability. (2) However, neither IT resources nor organizational resources directly provide firms with competitive advantage. Instead, business integration capability built from the two resources plays a mediating role through which business achieves competitive advantage.     

一个企业应用集成的设计模式：Hub

The Enterprise Application Integration (EAI) is a challenge of modern enterprise. How much effect of information system in enterprise business implement process that depends on the degree of inner function and information integration of formation system. The choice of EAI methods not only affects the investment of constructing information system and protecting /using old system, but also determines the efficiency of new system. This paper presents a design pattern, named Hub method, from the view of application integration, which adopts the idea in heterogeneous circumstance focusing on interface encapsulating about controlling information exchange and workflow handling. It also gives an implement method and a framework of the Hub in this paper, which is applied on business process management. And a good performance is achieved in controlling information exchange and workflow handling among enterprise applications. It not only improves system integration capability, stich as expansibility, flexibility, and opening through the method of the Hub, but also takes a great advance in soft reuse during software designing and implementing.     

Adaptive integration activity management for on demand business process collaboration

Today businesses are interacting and collaborating more often in the context of a business value chain involving a variety of partners to deliver products and services. Business to business (B2B) connectivity, Enterprise Application Integration (EAI) and general business collaboration processes are becoming more critical in operating and managing efficient enterprises. The required level of inter and intra enterprise integration is generally a large undertaking and involves substantial development and customization efforts. In this paper, we propose an adaptive integration activity management approach based on web services technologies to reduce code changes associated with business process integration in a distributed collaboration environment. Specifically, we present a concept of activity chain to capture non-deterministic process flows as well as deterministic process flows in a uniform manner. Then an Activity Ontology is introduced to capture the integration requirements that include adaptation behaviors, action properties, business rules, and access control policy references. The unique ontology representation and management of the integration activities provides a uniform way to integrate additional internal and external business applications to reduce the need for pre-defined and hard-wired integration methods and to minimize code changes to existing components in an existing business collaboration and integration (B2B/EAI) infrastructure. In addition, a Petri-Net modeling exercise of the proposed integration activity management is performed to help better understand the actual system and improve the system design beforehand.

Business process integration as a solution to the implementation of supply chain management systems

In the domain of supply chain management (SCM), various software packages have been developed for planning business strategies. To solve the problem of system productivity in applying planning packages, we propose a solution concept, business process integration (BPI), which fuses workflow and enterprise application integration (EAI) technology. Two characteristic policies are included in BPI. The first is to design the minimum set of business processes for real-time information sharing with planning packages without changing other processes. The second is to integrate several systems with EAI technology and to manage their execution with a workflow tool. Based on these policies, we propose various design templates and integration adapters. Our evaluation shows that using BPI, a target system can be developed with less manpower, in less time, and with higher quality than previous methods.     

Workflow Management Systems and ERP Systems: Differences, Commonalities, and Applications

Two important classes of information systems, Workflow Management Systems (WfMSs) and Enterprise Resource Planning (ERP) systems, have been used to support e-business process redesign, integration, and management. While both technologies can help with business process automation, data transfer, and information sharing, the technological approach and features of solutions provided by WfMS and ERP are different. Currently, there is a lack of understanding of these two classes of information systems in the industry and academia, thus hindering their effective applications. In this paper, we present a comprehensive comparison between these two classes of systems. We discuss how the two types of systems can be used independently or together to develop intra- and inter-organizational application solutions. In particular, we also explore the roles of WfMS and ERP in the next generation of IT architecture based on Web Services. Our findings should help businesses make better decisions in the adoption of both WfMS and ERP in their e-business strategies.
