Introduction The waterfall model is the most common model of all software development life cycle models. It is very simple to understand and use. In a waterfall model‚ each phase must be completed before the next phase can start. At the end of each phase‚ a review takes place to determine if the project is on the right path and whether or not the project should be continued. Here phases do not overlap with each other. Waterfall model is a sequential design process in which progress is seen

The waterfall model is a sequential design process‚ often used in software development processes‚ in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception‚ Initiation‚ Analysis‚ Design‚Construction‚ Testing and Maintenance. The waterfall development model originates in the manufacturing and constructionindustries; highly structured physical environments in which after-the-fact changes are prohibitively costly‚ if not impossible. Since no formal software

I will be explaining a little more in-depth of how the Systems Development Life Cycle (SDLC) operates. The SDLC process is a Systems Development Methodology (SDM) “which is basically the process most businesses go through to develop and maintain an Information System.” (Ross A. Malaga‚ (2005) Information Systems Technology‚ Published by Prentice Hall. Page 285. Copyright 2005 Pearson Education) The SDLC contains seven major phases; I am going to start on the first which is‚ Planning. Planning is

Modified Waterfall model is a derivation of the old Waterfall model. It provides an orderly sequence of developmental steps with flexible iterative phases that will facilitate the sufficiency and relevance of documentation and references whereby ensuring the quality‚ reliability‚ and maintainability of the developed custom system. By utilizing this concept‚ the researchers will be able to maximize and exhaust the resources and data available whilst developing the framework for the system in an iterative

disadvantages of Waterfall model. When to use it? When not to use it? How is it related to the Scope? (25 points) Answer – As the name suggests it is a simple process which is one way and does not have flexibility to revise the process phase already completed same as water once fall cannot jump back to its initial position. In this model one phase is completed and reviewed fully to enter the next phase. In this model phase do not overlap. Advantages :- • It is a simple model. • Each
