Question

What is the main difference between maintenance and initial development of a system?

a.

The changes are being made to an existing product

b.

The system is developed from scratch

c.

The time pressure is less during maintenance

d.

The system's entropy decreases during maintenance

Posted under Software Life Cycle Models Software Engineering

Answer: (a).The changes are being made to an existing product Explanation:A considerable maintenance effort is inevitable. Each maintenance task, whether it concerns repairing an error or adapting a system to new user requirements, in principle entails all aspects of the initial development cycle. During maintenance, we also have to analyze the problem and conceive a design which is subsequently implemented and tested. The first big difference is that these changes are being made to an existing product.
