Information Systems Engineering
An interdisciplinary approach and means to enable the realization of successful information systems.
It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, then proceeding with design synthesis, and system validation
Type of IS
Transaction processing system (TPS)
Management information system (MIS)
Decision support system (DSS)
Expert system
Communications and collaboration system
Office automation system
The activities of information systems development
System Survey
The SLDC phase also consists of three main points: system identification, selection, and system planning
Needs Analysis
System requirements analysis is a technique for solving problems by decomposing the components of the system.
Design
The design or design of system development is intended to provide a complete blueprint as a guideline for the IT team (especially programmers) in making applications.
Implementation
The stage of developing this information system is to work on a previously designed development.
Testing
A system needs to be tested to ensure that the development carried out is appropriate or not with the expected results.
Change and Maintenance
This step covers the whole process in order to ensure the continuity, smoothness and improvement of the system.
