Assignment Help:

Explain the waterfall model. Explain why it is more advantageous than adhoc methods.

Ans Waterfall Model:

1.The waterfall model is a chronological software development process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Initiation, Conception, analysis, design (validation) and testing Construction and maintenance.

2. The first official description of the waterfall model is given by Winston W. Royce in 1950 nevertheless popular in 1970 and further refined by Barry Boehm.

3. To follow the waterfall model one carries on from one phase to the next in a purely sequential manner. For instance one first completes requirements specifications which are set in stone. When the requirements are completely completed one proceeds to design.

4. Process structured as a tumble of phases where output of one is input of next.

5. Several variants of model depending on organization and specific project. However underlying phases are same for all.
