POWER SYSTEM ANALYSIS AND DESIGN CHAPTER 1
QUESTIONS AND ANSWERS
Information system - CORRECT ANSWER✅✅✅A set of interrelated components that
collects processes stores and provides as output the information needed to complete business task
. Always includes people who operate the system and carry out some of the work
Systems analysis - CORRECT ANSWER✅✅✅Those system development activities that
enable a person to understand and specify what the new system should accomplish
Systems design - CORRECT ANSWER✅✅✅System development activities that enable a
person to describe in detail how the resulting information system will actually be implemented
Project - CORRECT ANSWER✅✅✅A planned undertaking that has a beginning,end, and
produces end results
SDLC - CORRECT ANSWER✅✅✅System development life cycle
System development life cycle - CORRECT ANSWER✅✅✅A framework that identifies all
the activities required to research, build, deploy, and often maintain an information system
System development process - CORRECT ANSWER✅✅✅Or system development
methodology, a set of comprehensive guidelines for carrying out all the activities of each core
processor of the SDLC
Name the SDLC core processes - CORRECT ANSWER✅✅✅1. Identify the problem and
obtain approval
2. Plan and monitor the project
3. Discover and understand the details of problem or need
4. Design system components
5. Build, test,and integrate system components
,6. Complete system tests and deploy the solution
Agile Development - CORRECT ANSWER✅✅✅An information system development
process that emphasizes flexibility and rapid response to anticipate new and changing
requirements during development
Iterative development - CORRECT ANSWER✅✅✅An approach to system development in
which the system is "grown" piece by piece through multiple mini projects called iterations
Subsystem - CORRECT ANSWER✅✅✅An identifiable and fully functional part of a
complete system
The planning process for an iteration consists of three steps: - CORRECT ANSWER✅✅✅-
Identify the tasks required for the iteration
-Organize and sequence these tasks into a schedule
-Identify required resources (especially people) and assign people to tasks
WBS - CORRECT ANSWER✅✅✅Work breakdown structure
What is the WBS - CORRECT ANSWER✅✅✅After tasks of an iteration are identified,
they are compiled and organized into a document by order of importance, this includes estimates
of how long each task will take.
Iteration schedule - CORRECT ANSWER✅✅✅Tasks taken from the WBS and placed them
on day-by-day sequence.
Two core process 1 activities (called pre-project activities) - CORRECT ANSWER✅✅✅-
Identify the problem and document the objective of the solution system
-Obtain approval to commence the project
, System Vision Document - CORRECT ANSWER✅✅✅Document that shows the problem
description, system capabilities, and business benefits.
Three core process 2 activities - CORRECT ANSWER✅✅✅-Determine the major
components (functional areas) that are needed
-Define the iterations and assign each functional area to an iteration
-Determine team members and responsibilities
Core process 3 activities: - CORRECT ANSWER✅✅✅-Do fact-finding tasks to understand
the requirements
-Develop a list of use cases and a use case diagram
-Develop a list of classes and a class diagram, define user experience with sketches of screens
and reports needed for each use case
Use case - CORRECT ANSWER✅✅✅a document showing a case or situation where the
system is used.
ex/USE CASE: Look up supplier, DESCRIPTION: using suppler name, find supplier
information and contacts
Domain classes - CORRECT ANSWER✅✅✅Identifies the things in the real world that the
system needs to know about and keep track of. To find domain classes, we look for all objects or
things that a system uses or captures.
EX/Object class: Supplier Attributes: Supplier name, address, description, comments
Domain class diagram: - CORRECT ANSWER✅✅✅a visual diagram of domain classes,
their attributes, and their associations with other classes
Use case description - CORRECT ANSWER✅✅✅a method for documenting details of a
use case, to document interactions between the user and the system
