How quickly can I access data? How many lines of program code?

How easily can I retrieve data? How can we cut down CPU time?

How much clerical support do I need? What is the most efficient way of storingdata?

Information System Success: Individual and OrganizationalDeterminants by Rajiv Sabherwal, Anand Jeyaraj, and CharlesChowa of the University of Missouri-St. Louis.

A study focusing on information systems says that qualityand usefulness trump user satisfaction in the quest forsuccess. The findings are the subject of a paper in the

Management Insights section of the current issue ofManagement Science, the flagship journal of the Institutefor Operations Research and the Management Sciences(INFORMS).

Management Insights, a regular feature of the journal, is adigest of important research in business, management,operations research, and management science. It appearsin every issue of the monthly journal.

Based on empirical research conducted between 1980 and 2004, the study examines

four aspects of information systems (IS) success: system quality, perceived

usefulness, user satisfaction, and system use. The authors highlight the

importance of system quality, which affects all other aspects of IS success. They also

observe that system quality and perceived usefulness but, curiously, not user

satisfaction, influence the extent to which the system is used.

The studys results suggest that system developers and managers should concentrate

on developing better systems rather than focusing on increased user satisfaction with the system.

The analysis also suggests that four long-term measures related to information

systems are particularly important: ( 1) IS training, (2) improving individuals

attitudes toward information systems, (3) gaining top-management supportfor information systems, and (4) developing organizational structures that

facilitate use of information systems, such as help desks and online user assistance.

Challenges- Widespread poverty in Bangladesh led to corruptions as individuals rely on bribes

to maintain their livelihoodsBRIS viewed as a threat to corrupt activities resistance to adopt the changes A severe lack of IT skills within the Bangladesh Public sectorProblem increased as appointments made on the basis of seniority and political

involvement

Mant It professionals not properly qualified to design or maintain informationsustemThe system budget was severely constrained due to limited funds

KEY to successDevelopment teams sensitivity to these issues Creative approach to system buildingRealization the importance of young and talented staffEfforts on changing the existing structure and processes

Automated system free from redundant and inefficient processes

Value of starting small but thinking big

Project started with a small pilot, but was designed with an eye towardfuture integration with other possibly yet undeveloped systems
