Software Development Process and Waterfall Model free essay sample

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 developmentmethodologies existed at the time, this hardware-oriented model was simply adapted for software development. The first formal description of the waterfall model is often cited as a 1970 article byWinston W. Royce,[1] though Royce did not use the term waterfall in this article. Royce presented this model as an example of a flawed, non-working model (Royce 1970).
