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.
Bottom up design: This design leads to a style of design where we decide how to join these modules to give larger ones; to combine those to give even larger ones, and so on, till
Determine the advantages of spiral model In this model Software development starts with lesser requirements specification, lesser risk analysisetc. Radical dimension this model
Q. Describe incremental model? Define core product and detailed plan. Ans. The incremental model is proposed by D.L PARNAS. It is basically implemented by combining elements
Define debugging. Debugging is defined as the process of removal of defect. It occurs as a consequence of successful testing.
