Importance of Software Engineering

As the application domains of software are becoming complicated and design of big software without a systematic approach is virtually impossible, the field of software engineering is increasingly gaining importance. It is now developing like an industry. Thus, the industry has to answer following or similar queries of clients:

1. What is the best approach to design of software?
2. Why the cost of software is too high?
3. Why can’t we find all errors?
4. Why is there always some gap between claimed performance and actual performance?

To answer all such queries, software development has adopted a systematic approach. Software development should not remain an art. Scientific basis for cost, duration, risks, defects etc. are required. For quality assurance, product qualities and process qualities and must be made measurable as far as possible by developing metrics for them.
