Factors affecting the implementation success of Internet-based information systems

The Internet has come to revolutionize the way in which business conducts commercial activities. In this paper, we report on the development of a model of Internet-based information systems (IIS) implementation in business-to-consumer electronic commerce based on IS implementation and technology innovation–implementation studies. Our research model suggests that eight factors, comprising the characteristics of IIS technology innovation, organizational factors, and IS related factors, affect the implementation success of IIS. IIS themselves are characterized by three dimensions: volume, sophistication, and information contents. The suggested model was empirically tested using survey results from Korean companies that have adopted IIS. The results of multivariate regression analysis reveal that compatibility and IS infrastructure are key determinants of the extent of IIS implementation (in terms of volume, sophistication, and information contents). IS expertise potentially affects the extent of IIS implementation.     

Measuring implementation outcome: beyond success and failure

This paper proposes a framework for measuring the impact of a computer-based application in an organization. Recognizing the complexity of the implementation process, the framework is multi-dimensional: it seeks to measure the outcome of an implementation effort on both the people and tasks affected as separate from user's definition of “success”. The framework can be used to support either the quantitative or case study methodologies used in implementation research. Finally, the authors describe a field test of the framework to demonstrate its usefulness in an organizational setting.     

我国企业实施ERP项目的外部风险分析

企业成功实施ERP项目，将会为企业带来巨大的综合效益，但在ERP实施的过程中，企业也会同样面临着巨大的失败风险。到目前为止，虽然我国许多企业都在积极尝试和已经实施ERP项目，但成功率却十分低。因此，充分认识ERP实施过程中企业所面临的各种风险，进而正确地估计和控制风险，从而降低风险，才有可能提高ERP成功实施的概率。本文较详细地剖析了企业在实施ERP过程中所草临的各种外部风险，这些分析将会为企业成功实施ERP项目提供有益的帮助。

A workbook-based methodology for implementing concurrent engineering

Concurrent Engineering demands a new way of working and many organisations experience difficulty during implementation. The research described in this paper has the aim to develop a paper-based workbook style methodology that companies can use to increase the benefits generated by Concurrent Engineering, while reducing implementation costs, risk and time.

The three-stage methodology provides guidance based on knowledge accumulated from implementation experience and best practitioners. It encourages companies to learn to manage their Concurrent Engineering implementation by taking actions which expose them to new and valuable experiences. This helps to continuously improve understanding of how to maximise the benefits from Concurrent Engineering.

The methodology is particularly designed to cater for organisational and contextual uniqueness, as Concurrent Engineering implementations will vary from company to company. Using key actions which improve the Concurrent Engineering implementation process, individual companies can develop their own ‘best practice’ for product development. The methodology ensures that key implementation issues, which are primarily human and organisational, are addressed using simple but proven techniques.

This paper describes the key issues that the majority of companies face when implementing Concurrent Engineering. The structure of the methodology is described to show how the issues are addressed and resolved. The key actions used to improve the Concurrent Engineering implementation process are explained and their inclusion in the implementation methodology described.

Relevance to industry

Implementation of Concurrent Engineering concepts in manufacturing industry has not been a straightforward process. This paper describes a workbook-style tool that manufacturing companies can use to accelerate and improve their Concurrent Engineering implementation.     

A workbench for computational geometry

We describe the design and implementation of a workbench for computational geometry. We discuss issues arising from this implementation, including comparisons of different algorithms for constant factors, code size, and ease of implementation. The workbench is not just a library of computational geometry algorithms and data structures, but is designed as a geometrical programming environment, providing tools for: creating, editing, and manipulating geometric objects; demonstrating and animating geometric algorithms; and, most importantly, for implementing and maintaining complex geometric algorithms.This research was partially supported by the Natural Sciences and Engineering Research Council of Canada, Carleton University, and the Univeristy of Passau. Work on this project was carried out in part while A. Knight and J.-R. Sack were at the University of Passau.     

PIT: A macro-implemented implementation language

An implementation technique called PIT, for pseudo instructional technique, is described which utilizes the macro capabilities of most macro assemblers. A low level machine architecture is described via a set of macros that include some ‘high level’ features. Since the macros manipulate computer words, and refer to actual registers, their implementation in a system is relatively efficient, but since they do not reflect any one particular hardware design, they can be implemented by almost any macro assembler. Tests are built into the macros so that a PIT program will run without change on any machine that has defined these macros This technique should provide an alternative to using higher level languages as implementation languages if the object code produced by those compilers is deemed too slow (or too large) for the application that is being programmed.

Ergonomics practice in manufacturing

To improve the practice of ergonomics, particularly its implementation in manufacturing, the mission of the discipline itself must be examined with respect to the mission of manufacturing industry. Examples of theoretical foundations of ergonomics show a consistent response to practical demands. The environment in which ergonomics operates, in this case manufacturing, is also responding to changed demands. Global competition is forcing industries to be concerned with both their strategic plans and the detailed implementation of continuous improvement. Both concerns have strong implications for how ergonomics practice is conducted. Examples of successful ergonomics implementation in this changing environment suggest that the profession should consider operating at a more strategic level if it wishes to achieve detailed changes at a lower level.
