Systems analysis and design is the process of creating and maintaining information systems. The classic methodology used in systems analysis and design to develop information systems is called the systems development life cycle (SDLC).

Because the purpose of an information system is to support a business process, we have to understand the business process before we can design the information system.

Every company must develop a competitive strategy. Your competitive strategy is your company’s organized response to the industry structure of the industry in which it operates, and, thus, how to compete within that space.
