Chapter 12 Flashcards
Using an organized sequence of activities to study a problem or opportunity using systems thinking.
Systems analysis and design
Trying to recognize systems and the new interrelationships and components of systems in any situation.
Systems thinking
Evaluating the success of a solution after it has
been implemented
Postimplementation review
Your evaluation shows that benefits outweigh costs for a proposed system.
Cost/benefit analysis
The costs of acquiring computer hardware,
software, and specialists.
Tangible - Costs
Loss of customer goodwill caused by errors in a
new system
Intangible - Costs
Increases in profits caused by a new system.
Tangible - Benefits
Improved employee morale caused by efficiency
and effectiveness of a new system.
Intangible- Benefits
A multistep process to conceive, design, and
implement an information system.
Systems approach
A diagram or blueprint of a system that shows
what it does without regard to how it does it
Logical model
Determines the organizational, economic,
technical, and operational feasibility of a proposed
information system.
Feasibility study
The goal of this feasibility analysis category is
to determine whether the proposed system will
provide positive economic benefits.
Economic feasibility
Reliable hardware and software are available to
implement a proposed system.
Technical feasibility
Determining whether or not any copyright or
patent infringements may exist as the result of a
new system
Legal/political feasibility
Do we have the right people to operate the new
system?
Human factors feasibility
A multistage process for studying in detail the
information needs of users and any information
systems presently used, and then developing a
system to correct a problem or improve operations.
Systems development life cycle
A detailed description of user information
needs and the input, processing, output, storage, and control capabilities required to
meet those needs.
Functional requirements
Systems design should focus on developing user friendly input and output methods for a system.
User interface design
A detailed description of the hardware, software,
people, network, and data resources and information
products required by a proposed system.
System specifications
Acquiring hardware and software, testing and
documenting a proposed system, and training
people to use it.
Systems implementation
Making improvements to an operational system.
Systems maintenance
An interactive and iterative process of developing and refining information system prototypes.
Prototyping
Managers and business specialists can develop
their own e-business applications.
End-user development
Correcting, converting, filtering, consolidating,
and organizing data when replacing an old
system.
Data conversion
Operate in parallel with the old system, use a test site, switch in stages, or cut over immediately to a new system.
Conversion
Checking whether hardware and software work
properly for end users.
System testing
Keeping an IS project on time and within its
budget would be a major goal.
Project Management
A user manual communicates the design and
operating procedures of a system.
Documentation
Cost and benefits that can be quantified with a
high degree of certainty
Tangible
The degree to which a proposed system fits with
the business environment and organizational
objectives.
Operational feasibility
Costs and benefits of a new system that are hard to quantify.
Intangible
A phase within systems analysis focused
on understanding the organization and its
environment.
Organizational analysis
The process by which a system goes from designs and blueprints to becoming a working system.
Implementation process
