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.
Configuration Management: Because of several reasons, software changes during its life cycle. As a result of the changes made, many versions of the software exist at one time.
Question: (a) Describe fully the first five basic steps in software cost estimation. (b) What are the main differences between COCOMO1 and COCOMO2 cost estimation models?
An identified set of software features to be calculated under specified conditions by comparing actual behavior with the needed behavior described in the software documentation.
What is software maintenance Alters to the software are made in response to altered requirements but the fundamental structure of the software remains same.
