Exam 13: Developing Information Systems

"The system designer creates a working prototype quickly,using tools for rapidly generating software" describes which step in the prototyping process?

Prototyping is more iterative than the conventional lifecycle.

System testing

Rationalization of procedures describes a radical rethinking of the business models.

In the traditional systems development lifecycle,end users:

A structure chart is a bottom-up chart,showing each level of design,its relationship to other levels,and its place in the overall design structure.

Once the existing process is ________ in terms of time and cost,the process design team will try to improve the process by designing a new one.

The direct cutover strategy replaces the old system entirely with the new system on an appointed day.

There are alternative methodologies for modelling and designing systems,the most prominent are ________.

________ is a specific measure of quality,representing 3.4 defects per million opportunities.

A(n)________ is the model or blueprint for an information system solution and consists of all the specifications that will deliver the functions identified during systems analysis.

Object-oriented development uses the kernel as the basic unit of systems analysis and design.

Once a process has been implemented and optimized,it needs to be measured twice.

The ________ is a top-down chart,showing each level of design,its relationship to other levels,and its place in the overall design structure.

The ________ details the system specifications that will deliver the functions identified during systems analysis.

John is in the process of developing a new system.John is defining the problem,identifying its causes,specifying the solution,and identifying the information requirements that must be met by a system solution.John creates a road map of the existing organization and systems,identifying the primary owners and users of data along with existing hardware and software.John will then detail the problems of existing systems.By examining documents,work papers,and procedures;observing system operations;and interviewing key users of the systems,John can identify the problem areas and objectives a solution would achieve.John is in which stage of system development?

Documentation reveals how well the system has met its original objectives.

Groups of objects are assembled into software components for common functions,which can be combined into large-scale business applications,in which type of software development?

________ allows a software package to be modified to meet an organization's unique requirements without destroying the integrity of the package software.

In object-oriented development
