Briefly identify the four types of installation.
The four types of installation are direct, parallel, single location, and phased. Changing over from the
old information system to a new one by turning off the old system as the new one is turned on is called
direct installation. Parallel installation involves running the old information system and the new one at
the same time until management decides the old system can be turned off. Single location installation
involves trying out a new information system at one site and using the experience to decide if and how
the new system should be deployed throughout the organization. Changing over from the old
information system to a new one incrementally, starting with one or a few functional components and
then gradually extending the installation to cover the whole new system is commonly called phased
installation.

Briefly identify and categorize the seven different types of tests as proposed by Mosley.
Software application testing includes several different types of tests. As indicated in the text, Mosley
(1993) classifies the techniques based on whether they use static or dynamic techniques, and whether
the test is automated or manual. While static means the code being tested is not executed, dynamic
does involve the execution of code. Automation indicates that the computer performs the testing;
manual means that people perform the testing. Four distinct categories are identified: (1) static,
manual, (2) static, automated, (3) dynamic, manual, and (4) dynamic, automated. The first category
contains inspections; the second category contains syntax checking. The third category contains
walkthroughs and desk checking; the fourth category contains unit test, integration test, and system
test.

Define system documentation, user documentation, internal documentation, and external
documentation.
System documentation is detailed information about a system’s design specifications, its internal
workings, and its functionality. Internal documentation and external documentation are two types of
system documentation. Internal documentation is system documentation that is part of the program
source code or is generated at compile time. External documentation is system documentation that
includes the outcome of such structured diagramming techniques as data flow and entity-relationship
diagrams. User documentation refers to written or other visual information about an application
system, how it works, and how to use it.
172.
Identify several types of user documentation.
The text identified several types of user documentation. These types include a reference guide, a
user’s guide, a release description, a systems administrator’s guide, and an acceptance sign-off. A
reference guide consists of an exhaustive list of the system’s functions and commands and is usually in
alphabetical order. This purpose of the user’s guide is to provide information on how users can use
computer systems to perform specific tasks. A release description provides information about a new
system release, including a list of complete documentation for the new release, features and
enhancements, known problems and how they have been dealt with in the new release, and
information about installation. The systems administrator’s guide is intended for individuals who will
install and administer the system. It contains information about the network on which the system will
run, software interfaces for peripherals, troubleshooting, and setting up user accounts. Users
demonstrate their approval by recording their signatures on an acceptance sign-off.
173.
Briefly identify the tasks associated with closing down the project.
The first task encompasses many activities. These activities include team member evaluations, team
member reassignments, and notifying affected parties of the project ending. The second task
encompasses post-project reviews with both management and customers; its purpose is to critique the
project, its methods, its deliverables, and its management. The third task involves closing out the
customer contract.

communication and customer service.

What is an electronic performance support system? What forms might this system take?
An electronic performance support system is a component of a software package or application in
which training and educational information is embedded. An EPSS can be implemented as a tutorial,
expert system shell, or hypertext jumps to reference material.
177.
What factors influence implementation success?
While management support and user involvement impact the successful implementation of a new
system, other factors play a part. Commitment to the project, commitment to change, the extent of
project definition, user expectations, and political environment impact the implementation process.
Additionally, Lucas identified six factors that influence the extent to which a system is used; these
include user’s personal stake, system characteristics, user demographics, organization support,
performance, and satisfaction.

How can you support intermittent users of a system?
Intermittent system users require “point of need support.” Their needs can be addressed through the
system interface and on-line help facilities.
