Requirements analysis for integrating e-government information systems

Abstract

Nowadays organizations use a large number of information systems to solve their business problems. Most of these applications and systems exist on various platforms which have been developed at different times. The challenge with which organizations are often faced is to apply a method which can easily integrate these systems and applications in a way that they interact and communicate with each other. On the other hand, prioritizing the requirements is one of the important topics in information systems architecture. After specifying the requirements in the architecture of systems, they should be prioritized in accordance with their importance so that the available time and resources can be allocated to them in order to implement the project. This would lead to the more favorable use of time and project resources. This applied study is an analytical survey. Reviewing the theoretical and empirical background pertaining to the research subject and considering the requirements of information systems in Iran, a questionnaire including 23 questions was distributed among 58 IT experts to identify and prioritize the indices of requirements and necessities for integrating information systems. This was based on the standard ISIR – ISO 25030 issued by the Institute of Standard and Industrial Research of Iran. The results indicated that the index of reliability was ranked the first place with 0.81 while the index of efficiency was ranked the second place with 0.76. Then the indices of maintenance, usability, functionality, and portability were ranked the other places with 0.66, 0.64, 0.59, and 0.51, respectively.
