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
