Why do we need Software Engineering?
The need of software engineering arises because of higher rate of change in user requirements and environment on which the software is working.
Large software – When a company needs a large software to build, it must use a software engineering methodology in order to handle such a project without any issues.
Scalability - The always growing and adapting nature of software hugely depends upon the environment in which the user works. If the nature of software is always changing, new enhancements need to be done on the existing one. This is where software engineering plays a good role. If the software process were not based on scientific and engineering concepts, it would be easier to re-create new software than to scale an existing one.
Cost and time - As hardware industry has shown its skills and huge manufacturing has lower down the price of computer and electronic hardware. But the cost of software remains high for not adapting the proper process. Software engineering programmers plan everything and reduce all those things that are not required thus reduce the development time.
Quality Management- Better process of software development provides better and quality software product.
Reduces complexity- Large task are broken down into smaller ones and solved one at a time in software engineering. Individual solutions are found for each of these issues. Testing smallar parts makes things easier.
Productivity- Because it contains testing systems at every level, proper care is done to maintain software productivity.
