Question

Give an example of how efforts in the development of software can pay dividends later in software maintenance. What is evolutionary prototyping? Explain how the lack of metrics for measuring certain software properties affects the software engineering discipline. Would you expect a metric for measuring the complexity of a software system to be cumulative in the sense that the complexity of a complete system would be the sum of the complexities of its parts? Explain your answer. Would you expect a metric for measuring the complexity of a software system to be commutative in the sense that the complexity of a complete system would be the same if it were originally developed with feature X and had feature Y added later or if it were originally developed with feature Y and had feature X added later? Explain your answer.

Explanation / Answer

2.Evolutionary prototyping is lifecycle model in which the system is developed in        increments so that it can readily be modified in response to end user and customer feedback

In evolutionary prototyping the system concept is developed as you move through the project.You being by developing the most visible aspect of the system.
