Answer to Question 1

FALSE

Answer to Question 2

Features of the systems development lifecycle include: sequential step-by-step formal process, written specification and approvals, and limited role of users. Features of prototyping include: requirements specified dynamically with experimental system; rapid, informal, and iterative process; users continually interact with the prototype. Features of end-user development include: systems created by end users using fourth-generation software tools, rapid and informal, minimal role of information systems specialists. Applications software packages are appropriate for universal functions with standard processes that do not change a great deal over time. However, customization may be needed if the software doesn't match the business processes. If a firm does not want to use its internal resources to build or operate information systems, it can outsource the work to an external organization that specializes in providing these services. The vendor may or may not be responsible for operating the system on its own computers.
