First no better way had been developed and second software was not that complex. As software grew more complicated and organizations relied on computers for more of their operations including finances and even human lives this laissez faire approach to programming gave way to more disciplined methods. The overall framework in which software is conceived developed and maintained is known as the Software Development Life Cycle SDLC . This chapter discusses the various types of SDLCs along with their advantages and disadvantages. A life cycle model defines the phases milestones deliverables and evaluation criteria of the software development process. These form the basis of the work breakdown structure WBS used for project planning and management.
