The main goal within an organization when implementing an information system is to increase efficiency in organization activity by means of IT.
For example: automatic information processing, adequate information and document management.
The implementation stages of an information system includes:
Problem analysis and specification design: The IT team analyses and defines the problem accurately. However, the users have to describe their complete requirements or specifications. Therefore, the involvement of the organization in providing complete and precise specifications for its needs are essential. Incomplete requirements will lead to inadequate systems and disadvantages in resource allocation for both the IT team and organization.
Design and implementation of the application: This stage is performed by the IT teams based on the specifications required. This stages examines the “how to do” and “do it” by the IT team. This involves the architecture design, choosing programming languages and environments, application implementation and application testing.
System installation: This is performed within the organization as it takes into account the user feedback and, if necessary, make adjustments where it is required.
Maintenance: This stage comes after the system installation. It involves all the necessary operations in order to ensure that there is an efficient exploitation of the system within the organization and performs adjustments where it is required as well as developing the organization’s activity.
