Evaluating Information Systems
The adoption of Information Technology (IT) and Information Systems (IS) represents significant financial investments, with alternative perspectives to the evaluation domain coming from both the public and private sectors. As a result of increasing IT/IS budgets and their growing significance within the development of an organizational infrastructure, the evaluation and performance measurement of new technology remains a perennial issue for management. This book offers a refreshing and updated insight into the social fabric and technical dimensions of IT/IS evaluation together with insights into approaches used to measure the impact of information systems on its stakeholders. In doing so, it describes the portfolio of appraisal techniques that support the justification of IT/IS investments. Evaluating Information Systems explores the concept of evaluation as an evolutionary and dynamic process that takes into account the ability of enterprise technologies to integrate information systems within and between organisations. In particular, when set against a backdrop of organisational learning. It examines the changing portfolio of benefits, costs and risks associated with the adoption and diffusion of technology in today's global marketplace. Finally approaches to impact assessment through performance management and benchmarking is discussed.
Information Technology Evaluation Methods and Management
The evaluation of information technology and its business value are the subjects of many academic and business discussions. Investments in IT are growing extensively and business managers worry whether the benefits derived might not be as high as expected. This phenomenon is often called the IT investment paradox or the IT Black Hole: large sums of money are invested in IT that seem to be swallowed by a large black hole without rendering much return. How to measure the benefits of IT is the concern of Technology Evaluation Methods and Management. Different IT evaluation approaches and methods are discussed and illustrated with cases: traditional financial evaluations such as the return on investment, information economics and the recently introduced IT Balanced Scorecard. The latter approach is proposed as an ideal mechanism to support the IT/business alignment process and its related IT governance process.
Information management
Survey and study background In an effort to gain some answers on the 1ST capital investment (project selection) decision criteria used in practice, a survey was undertaken in 1990 of 80 American, British, Australian and New Zealand companies. A one-page survey form was used that provided 15 possible 1ST investment criteria, a means of indicating whether they are used or not, the percentage of projects to which each criterion is applied, and an overall ranking in terms of total project value for each criterion. The criteria are shown in Table 2.1. The criteria are categorized into financial, management, and development criteria. They were developed, first, through interviews with some 20 chief information officers (CIOs) in Britain and the United States. These CIOs were questioned on what criteria their organizations use in selecting 1ST investment projects, with the aim of developing a full list of the criteria used in practice. Secondly, the criteria and the form were tested and refined in a pilot study with some 12 companies. The criteria used in the survey and listed in Table 2.1 are primary level criteria.
