Chapter 1 Problems/Exercises1.)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?It’s important to use systems analysis and design methodologies when building a system because it ensure the quality of the system being built, it is also tested and you are following an appropriate process that is very structural. If you build a system in whatever way seems to be quick and easy, it can result in a poorly developed system, yes it can be easier and cheaper but in the long run it can require extra work to maintain and more money to maintain it. The value that is provided by using an engineering approach is well designed, precise and systematic. 8.) How might prototyping be used as part of the SDLC?Prototyping is part of the feasibility analysis phase of SDLC. A simulated prototype of the target system is created which gives the initial fee of the target system.
