Answer to Question 2

The systems development life cycle (SDLC) is the traditional process used to develop information systems and applications. Many early projects met with disaster, and companies and systems developers sifted through the ashes of those disasters to determine what went wrong. By the 1970s, most seasoned project managers agreed on the basic tasks that need to be performed to successfully build and maintain information systems. These basic tasks are combined into phases of systems development. SDLC rose to prominence when the U.S. Department of Defense required it on government contracts.
