Exam 10: Building Successful Information Systems

An example of an externally identified problem would be management voicing concern about an organization's lack of a competitive edge in the marketplace.

How do the phases of the systems development life cycle (SDLC) relate to each other?

_____ feasibility is concerned with whether a new system can be completed on time.

Using the joint application design (JAD) approach results in the collected requirements for the application being too narrow and one-dimensional in focus.

_____ uses an iterative process that repeats the design,development,and testing steps as needed,based on feedback from users.

Why are intangible benefits difficult to quantify?

Flowcharts are tools used in the structured systems analysis and design (SSAD) model for data analysis.

A(n) _____ chart,which is a project management technique,can be established using the critical path to list the completion time of a project on the x-axis and all the activities on the y-axis.

While using PERT (Program Evaluation Review Technique) and CPM (Critical Path Method) techniques,activities that are not on the critical path are more inflexible than those activities on the critical path.

_____ is similar to extreme programming (XP) in focusing on an incremental development process and timely delivery of working software,which has less emphasis on team coding and more emphasis on limiting a project's scope.

In a PERT (Program Evaluation Review Technique) or CPM (Critical Path Method) network,the critical path takes the shortest time to be completed.

The _____ document,which indicates the start of the design phase,is created during the requirements-gathering and analysis phase of the systems development life cycle (SDLC).

The creation of a system specifications document indicates the beginning of the analysis phase of the systems development life cycle (SDLC).

_____ is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project.

_____ is a philosophy and a software and system development methodology that focuses on the development,use,and reuse of small,self-contained blocks of codes to meet the software needs of an organization.

A ____ is a tool used in structured systems analysis and design (SSAD) analysis model that helps analysts understand the data requirements an information system must meet by defining data elements and showing the associations between them.

Explain the three disadvantages of outsourcing.

What are the five major dimensions of a feasibility study?

During the planning phase of the systems development life cycle (SDLC),the systems designer must define the symptoms rather than the underlying problem.

State the five capabilities of computer-aided systems engineering (CASE) tools.
