The four kinds of structural organizational change enabled by IT, in order from least to most risky, are
automation, rationalization, redesign, p?
employees are enabled
business processes are analyzed, simplified, and redesigned in
business process redesign
a bank has reworked its mortgage application process so that several steps are handled by computer software, and some steps are combined to reduce bottlenecks in processing. the goal is to gradually improve its efficiency over time. this is an example of
rationalization of procedures
an upscale organic foods grocery chain is implementing an information system that will enable it to add same-day home delivery of groceries to its customers. this is an example of

________ provides a methodology and tools for dealing with the organization's ongoing need to revice and optimize its numerous business processes

which of the following is not a tool provided by business process management software
capture and identify information system requirements for new systems
end user development
allows ends users to easily access data, create reports, and develop simple applications.
A(n)________ is an organizational change that involves rethinking the nature of the business and the nature of the organization itself
t/f the most common form of IT enabled organization change is business process redesign
(T/F) Rationalization of procedures describes a radical rethinking of the business models.
t/f organizations will adjust to new information systems without any special efforts if the system is a good system to begin with
t/f TQM describes the measurement of quality as 3.4 defects per million
which conversion process introduces the system first to a limited portion of the organization
pilot study strategy
Which process develops a detailed description of the functions that a new information system must perform?
shows how the new system will fulfill the information requirements.
Transferring data from a legacy system to the new system would be defined by which system design specification category?
tests each new program separately.
tests the functioning of the information system as a whole in order to determine if discrete modules will function together as planned
provides the final certification that the system is ready to be used in a production setting
in a parallel conversion strategy, the new system
and the old are run in parallel.
in the direct cutover conversion strategy, the new system
replaces the old one at another
Changes in hardware, software, documentation, or production to a production system to correct errors, meet new requirements, or improve processing efficiencies are termed:
In what stage of systems development are design specifications created?
a systems analysis includes a(n)_______ that is used to determine whether the solution is achievable from a financial, technical, and organizational standpoint
______ provide(s) a detailed statement of the information needs that a new system must satisfy, identifies who needs what information, and when, where, and how the information is needed
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
systems design document
during the _____ stage of system development, system specifications that were prepared during the design stage are translated into software code
_______ is the process of changing from the old system to the new system
(T/F) The system is not in production until conversion is complete.
t/f documentation reveals how well a system works from both a technical and end user standpoint
The entire system-building effort is driven by:
user information requirements.
The primary tool for representing a system's component processes and the flow of data between them is the:
data flow diagram
An entire information system is broken down into its subsystems by using
high level data flow diagrams
to understand and define the contents of data flows and data store, system builders use
a data dictionary
To show each level of a system's design, its relationship to other levels, and its place in the overall design structure, structured methodologies use:
in object oriented development
processing logic resides within objects.
in an object-oriented development framework for a university, how would the class Degree, Mathematics and Physics be related
degree is superclass to math and physics
object-oriented modeling is based on the concepts of
class and inheritance
object-oriented development could potentially reduce the time and cost of writing software because
objects are reusable
CASE tools automate
a native mobile app is
a stand alone application that doesn't use browser
_______ describe the transformation occurring within the lowest level of the data flow diagrams
organizational software packages often include _____ features that allow the software to be modified to meet organizational requirements
t/f a data flow diagram offers a logical and graphical model of information flow, partitioning a system into modules that show manageable levels of detail
t/f 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
(T/F) Objects are grouped into hierarchies, and hierarchies into classes.
(T/F) Object-oriented development is more incremental than traditional structured development.
(T/F) CASE tools facilitate the creation of clear documentation and the coordination of team development efforts.
The oldest method for building information systems is:
systems development life cycle
In the traditional systems development lifecycle, end users:
are limited to providing information requirements
in which type of systems building are the development stages organized so tasks in one stage are completed before the tasks in the next stage begin
You are an IT project manager for an advertising firm. The firm wishes to create an online survey tool that will be used to survey focus group reactions to products in development. The most important consideration for the firm is being able to offer the tool as soon as possible as a new corporate service. However, you know that many of the senior managers that are business owners of this project have difficulty in understanding technical or software development issues, and are likely to change their requirements during the course of development. What development method would be most successful for this project?
A systems building approach in which the system is developed as successive versions, each version reflecting requirements more accurately, is described to be ________.
When systems are created rapidly, without a formal development methodology:
testing and documentation may be inaccurate?
what is the primary driving factor in firms to select domestic outsourcing firms to build system solutions
to take advantage of technical skills
a software package evaluation process is often based on a series of questions sent to vendors called a/n
request for proposal
(T/F) The oldest method for building information systems is prototyping.
T/F Prototyping is more iterative than the conventional lifecycle.
t/f a prototype is a working version of an information system that is meant to be only a preliminary model
t/f end user developed systems can be completed more rapidly than those developed through the conventional systems lifecycle
t/f a primary benefit of offshore outsourcing is that this can substantially reduce hidden costs
what is the purpose of responsive web design
It allows one Web site to serve different platforms, such as tablets, PCs, and mobile phones.
what is 'responsive design' for mobile applications
design that responds to digital device and screen
As a technical project manager you have decided to propose implementing a prototyping methodology for a small Web-based design project. What is the order of steps you will follow in this project?
identify user requirements, develop prototype, use, revise
the process of creating workable information systems in a very short period of time is called
which type of systems development is characterized by significantly speeding up the design phase and the generation of information requirements and involving users at an intense level
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?
component based development
______ development focuses on rapid delivery of working software by breaking a large project into a series of small sub projects that are completed in short period of time using iteration and continuous feedback
compared to the use of proprietary components, web services promise to be less expensive and less difficult to implement because of
their ability to enable communication ____?
with a mobile web app
