Causality in the alignment of information technology and business strategy

The need for a link between information technology (IT) use and organizational strategy has been identified and discussed for a number of years. The thrust of this work argues that the motives for investment in IT should derive from firm objectives and, more particularly, from the strategic plan which the organization wishes to pursue. This paper argues that, often, mere lip service is paid to the strategic nature of IT. Further, strategy justification has become a tool for securing investment in IT by circumventing established organizational policy on investments. Many IT investments labelled ‘strategic’ appear to be operational in nature. This paper discusses the nature and evaluation of strategy and relates it to the literature on IT as a strategic tool. The extent to which the relationship between IT and strategy has altered over recent years is subsequently investigated. The implementation process is investigated and evidence of IT investment activities and the returns available to investing organizations are reviewed. The paper argues that there are a number of alternative views on the IT-strategy relationship, some of which are organizationally detrimental.     

Impacts of information systems and technology on productivity and competitiveness of the Portuguese banking sector: an empirical study

This paper presents a study of the Portuguese financial sector during the period 1994–1999. The research, based on previous studies about the productivity paradox of information systems and technology (IST) investments, examines the ‘services sector’ and includes the ‘human subsystem’ of an organisation, clients and employees, as variables of analysis. The conclusion from this research indicates a complementary effect (not substitution effect) between IST and labour, the strategic impact of IST in several organisation areas, and the need to design new functions, other than the traditional Cobb‐Douglas function, to evaluate the impact of IST on organisations.

Implementation of information technology in Africa: Understanding and explaining the results of ten years of implementation effort in a Tanzanian organization

This study traces attempts to introduce information technology into a management college in Africa, over a 10-year period from 1991 to 2001. The study uses an interpretative approach and is informed by information technology (IT) implementation literature. The case shows little progress over the 10-year period studied and the authors identify several explanations for this. The findings related to implementation, or the lack thereof, tie in well with the general IT implementation literature, suggesting that some of the key elements in the literature are of a fairly general and universal nature. The general nature of the literature does not provide the background for a deeper understanding of the issues and underlying levels of explanations. For this, more contextual factors need to be taken into account. The authors have been able to point to some of these sociocultural factors. However, this is an area where further research is needed. © 2006 Wiley Periodicals, Inc.

Acceptance of online banking information systems: an empirical case in a developing economy

This paper proposes an extended model of technology acceptance to understand potential users’ acceptance of online banking information systems (OBIS). The proposed model integrates key constructs from information systems and e-commerce acceptance research streams into the theoretical frame of the technology acceptance model. The model was tested on a sample of 353 Internet banking users in Pakistan. Using structural equation modelling with Analysis of Moment Structures software, data analysis showed considerable support for the extended hypothesised model. The results suggested that, in order of importance: perceived usefulness (PU), perceived ease of use (PEOU) and trust explained 45.7% of the variance in intended acceptance behaviour. Trust and technological self-efficacy (TSE) predicted 28.1% of the variance in PU. While in PEOU 21.8% of the variance was predicted by TSE, accessibility and terminology clarity. This study produced valuable insights into the factors that influence acceptance of OBIS by intended users and offers new ideas in understanding the acceptance of technology, especially in developing countries.

Organizational information management strategies

Abstract. Information technology is a key factor in competitiveness. Business managers increasingly have to make decisions in this field. Their involvement in planning and decision making should be active and genuine. There are numerous methods to support information systems planning and implementation. This study focuses on the organizational approach to generating plans. An interactive framework for evolutionary information systems planning is presented together with the results of applying this framework in six organizations. The author has been working with these organizations very intensively, using an action research approach. The main emphasis is on the success of the organizational method of creating information management strategies. The main finding is that an interactive way of generating strategies is not enough. The role of internal 'project champions' in both planning and implementation is extremely important. Outside facilitators cannot replace their contribution.

Toward more effective management of information technology benefits

A critical issue facing senior executives is how to improve the return on their information technology (IT) investments. The results of numerous studies are inconclusive as they have failed to show conclusively that IT investments produce expected payoffs. The purpose of this paper is to offer an explanation for the perceived lack of IT payoff and show how managers can improve the return on their IT investments. We argue that IT can provide significant benefits, but in many cases these benefits are not captured by the firm that made the investment. Instead, a large portion of the benefits are reaped by a variety of participants or stakeholders. The implications of this for managers is that they need to view IT payoff as a portfolio of benefits across many stakeholders. They must also understand and manage the distribution of the benefits within the portfolio to assure that benefits are transferred to the bottom line. The paper offers a framework for analyzing the nature and distribution of IT benefits among various stakeholder groups and concludes with a set of guidelines for measuring and managing these benefits.
