PHASE 4 :
SYSTEM IMPLEMENTATION

LESSON 12
SYSTEM IMPLEMENTATION

INTRODUCTION
In the previous lesson, we have learned several types of user interfaces and how to design a good user interface. In this lesson, we will discuss on system implementation. System implementation is the fourth phase in the system development life cycle (SDLC). The purpose of system implementation is to build a properly working system, install it in organization, replace and old systems, preparing system and user documentation and train users. This lesson consists of six sections: * Overview of system implementation * Coding * Testing * Installation * Documenting the system * Training

LEARNING OUTCOMES
At the end of this lesson, students should be able to : * explain the purpose of the implementation phase in the system development life cycle and activities involved * identify tasks involved during coding activity in system implementation * apply four types of testing in the system development * apply four installation strategies; direct, parallel, single location and phased installation * prepare the system and user documentation for the information system * conduct a training to system stakeholder

TERMINOLOGY No | Word | Definition | 1 | Coding | A process whereby the physical specifications created in the previous phases are turned into working computer codes by the programmer team | 2 | Installation | the process of moving from the current system to the new or enhanced system | 3 | Integration testing | A testing where it involves two or more modules that link each other | 4 | System implementation | A development, installation and testing of system components and delivery of that system into production | 5 | System testing | A testing where the it involves the integration of the whole programs into a system | 6 | Unit testing | A testing
