Exam 10: Building Successful Information Systems

What are the steps involved in prototyping?

The object-oriented approach treats process and data independently and is a sequential approach that requires completing the analysis before beginning the design.

What is the function of the models created during the analysis phase?

____________________ centers on a structured workshop where users and system professionals come together to develop an application.

Why is the formation of a task force important?

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

A ____ illustrates the logical steps in a process but does not show data elements and associations.

In ____________________,a small-scale version of the system is developed,but one that is large enough to illustrate the system's benefits and allow users to offer feedback.

Only tangible benefits should be included in an economic feasibility study since intangible benefits cannot be quantified.

During the ____ phase,the systems designer must define the problem the organization faces,taking care not to define symptoms rather than the underlying problem.

The systems development life cycle (SDLC)is also known as the ____.

A request for proposal (RFP)is usually prepared during the implementation phase and contains detailed information about the functional,technical,and business requirements of the proposed information system.

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

A ____ helps analysts understand the data requirements a system must meet by defining data elements and showing the associations between them.

During the planning phase,analysts investigate a proposed solution's feasibility and determine how best to present the solution to management to get funding.

What are the parts of the design phase?

____________________ tools are particularly helpful for investigation and analysis in large-scale projects because they automate parts of the design phase.

During the ____ phase,the information system is operating,enhancements and modifications to the system have been developed and tested,and hardware and software components have been added or replaced.

____ costs measure what you would miss by not having a system or feature.

____ users are employees who will use the system regularly,and they can offer important feedback on the system's strengths and weaknesses.
