To understand system development we need to recognize that a candidate system has a life cycle, just like a living system or a new product. In the present paper I have defined the system and its phases to develop a system. INTRODUCTION To operate system work one needs to understand the systems concept and how organizations operate as a system and then design appropriate computer based system that will meet organization requirements. It is actually a customized approach to use the computers for problem solving. System analysis and design have many stages recognition of the need for change, feasibility study, analysis of the present system, design of the candidate system, testing and implementation of the system and post implementation. These stages of the system analysis and principles of software design are discussed in detail. DEFINING SYSTEM ANALYSIS System analysis is the application of the systems approach to problem solving using computers. The term system is derived from the Greek word systema which means an organized relationship among functioning units or components. A system exists because it is designed to achieve one or more adjectives. Definition of a system suggests some characteristics that are present in all systems organization, interaction, interdependence, integration and a central objective. One can think of the systems approach as an organized way of dealing with a problem. In this dynamic world, the subject System Analysis and Design mainly deals with the software development activities. A collection of components that work together to realize some objective forms a system.
