MGMT 340 Business System Analysis Week 1
Chapter 1 Problems/Exercises
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. This also helps in pre-analyzing the behavior of the target system.
3.) In the section on choosing off-the-shelf software, eight criteria are proposed for evaluating alternative packages. Suppose the choice is between alternative custom software developers rather than prewritten packages. What criteria would be appropriate to select and compare among competing bidders for custom development of an application? Define each of these criteria.
= The criteria for evaluating alternative packages from custom software developers would be: cost, functionality, and response time. As with custom software, you know from your bid that vendor support, viability of vender, flexibility, documentation and ease of installation is taken care of, as the vendor will install the system, supply appropriate documentation, will ensure flexibility of...
