Information Systems Analysis and Design-Development Life Cycle- Businesses and organizations use various types of information systems to support the many processes needed to carry out their business functions. Each of these information systems has a particular purpose or focus, and each has a life of its own. This “life of its own” concept is called the systems development life cycle or SDLC, and it includes the entire process of planning, building, deploying, using, updating, and maintaining an information system. The development of a new information system involves several different, but related activities. These activities, or phases, usually include planning, analysis, design, implementation, and maintenance/support. In other words, SDLC is a conceptual model that guides project management in information system development.

The Merriam-Webster dictionary defines systems analysis as "the process of studying a procedure or business in order to identify its goals and purposes and create systems and procedures that will achieve them in an efficient way". Another view sees systems analysis as a problem-solving technique that decomposes a system into its component pieces for the purpose of the studying how well those component parts work and interact to accomplish their purpose.
