Organisational impact of information technology on the banking and insurance sector in Nigeria
Abstract The importance of information technology (IT) in the modern day business transaction cannot be over-emphasised. The impact assessment of the technology on any business is expedient so as to objectively determine its influence on a specific aspect of the organisation. This study therefore assessed the organisational impact of IT on some banks and insurance firms in Nigeria. Eight leading commercial banks and six highly rated insurance firms which have branches in Lagos, the commercial nerve centre of Nigeria, and two other important state capitals, were selected for this study. Data were obtained from both the customers and workers at the banks and insurance firms. The data were analysed using percentage and five-point Likert scale to objectively determine the local and global impacts of IT on the banks and insurance firms. The local impact criteria considered are: time savings, error rate reduction, enhanced management decision making, and improved service delivery. On the 5-point likert scale, there was positive impact on IT on the local criteria in the mean range of 1–3 at Lagos and Ibadan with Osogbo having a mean in the range of 3–5 which indicates otherwise. Also, the calculated mean of the IT impact on global criteria such as competitive advantage, high revenue generation, market segmentation and forecasting are in the range of 1–3 for all sampled cites. The study also revealed that there was positive impact of IT on both the induced local and global criteria. The induced local impact criteria identified are competitive advantage, market segmentation, high revenue generation, and forecasting while development of business niche, increased market share and network insecurity constituted the induced global impact criteria.
The Impact of Information Technology Investment on Bank Performance Considering the Role of Moderator Variables: Strategy and Environmental Dynamism
The performance impact of information technology (IT) investment is an important research topic that needs to take into consideration the role of key contextual factors. This study discussed and empirically tested the moderating effects of environmental dynamism and branch strategy on the impact of IT investment and other effective variables (number of employee and fixed asset) on branches performance. The study sample consisted of 102 branches of Parsian Bank and the empirical results, based on a moderated regression modeling approach. Specifically, IT investment appears to have a stronger positive impact on bank performance when there are greater environmental changes and more proactive branch strategy. According to our findings, banks considering IT investment should assess their environmental contexts and strategic directions.
Evaluating Information Systems Effectiveness - Part II: Comparing Evaluator Viewpoints
Evaluations of Management Information Systems (MIS) tend to be subjective and are influenced by the perceptions of system objectives, as well as the experiences with system performance in accomplishing organizational objectives. Consequently, the assessments of MIS effectiveness are often controversial and can be sources of disagreement and conflict between different functional groups involved in MIS implementation ᾢ users, MIS development, internal audit, and top management personnel. 
 
This article, the second of two parts, describes and compares the evaluator viewpoints on system effectiveness for these various functional groups. The first part, which appeared in the previous issue of the MIS Quarterly (Volume 5, Number 3) presented a conceptual hierarchy of system objectives and compared various approaches for evaluating accomplishment of objectives.
