• Systems design
It is a procedure of gathering and deciphering certainties, recognizing the issues, and decay of a framework into its segments.
Framework analysis is directed to study a framework or its parts so as to distinguish its destinations. It is a critical thinking procedure that improves the framework and guarantees that every one of the parts of the framework works productively to achieve its motivation.
