Explain why software testing should always be performed in stages and in an incremental manner. What percentage of programmers are the most qualified to test the programs that they have created?
An engineer who is good at building a wall may not be good at constructing a house or a multistory building with many dimensions. Similarly, a talented programmer who writes good programs may not have the required skills to develop and implement the software in a well-defined systematic approach. Explain how software engineering differs from conventional engineering. Provide 2 examples of how software engineering emphasizes the quality of the product, whereas conventional engineering emphasizes mass production of the product.

The AL Dhakaliya Software development team is currently working on a new application
development project. An initial study has determined that the size of the program will be
roughly 90,000 delivered source instructions (DSI). According to the project head, this
project should be considered as embedded software project.
