1. Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way seems to be “quick and easy?” What value is provided by using an “engineering” approach?

This sucks up even more time and financial resources. By using system analysis and design methodologies you can ensure the end product was executed properly.

8. How might prototyping be used as part of the SDLC?
