Abstract

Nowadays, the information system methodology is lifeblood of any successful project. The success is based on the quality of information and its technology over the globe. This could rely on the development and operation of computer based systems. To assure that you achieved the goal, there should be a perfect and ideal selection of the methodology, and quite simply it matches your needs. However, there should be some researchers have been written about NIMSAD, SSADM and ETHICS and with no doubt much will be written in the future. The purpose of this paper is to conducting a comparison between two methodologies effectively. Besides, the implementation of NIMSAD framework will take an integral part in this paper. Consequently, the implementation will illustrate the strength and weakness points of both methodologies. Eight principals' steps of NIMSAD will be examined to demonstrate various aspects of EHTICS and SSADM methodologies. This, however, will help to ensure the efficient performance which is the main goal of this work.
