INTRODUCTION TO SYSTEMS ANALYSIS 2022\2023 Meaning and importance of system Analysis A system consists of inputs, process, files and output and is designed to fulfill some useful purpose. Systems ... vary in levels of complexity, ranging from simple applications e.g. stock control to a complete set of systems, known as management of information systems (M.I.S). A system that has been converted to computer processing is referred to as a computer application and an integrated set of such systems is known as computer based management information systems (CBMIS) Development of a CBMIS is a complex process and because of this, systems have been developed bit by bit .The increase in complexity of systems has led to higher development cost and this highlights the need for effective system analysis. System analysis also referred to as system development refers to the process, which covers not only the study and examination of a system but also the design and implementation of a new and a better one. System analysis covers the review of the existing system leading to a design specification for a new system. It is a detailed study of current practices, files (storage), documents, working, methods etc from which can spring out ideas for new systems. This is based on the notion that you can’t improve a system until you understand it and what it is supposed to do.
