ISDS 406 Midterm 1 (Ch. 1 PlanningPhase)
Analysis models - correct answer ✔Part of the Analysis Phase (PADI);
describe how the business will operate if the new system is developed;
represent user/system interactions and the data and processes needed to
support the underlying business process.
Analysis Phase of SDLC - correct answer ✔The deliverables produced in the
analysis phase provide a general idea what the new system will do. These
deliverables are used as input to the design phase, which then refines them to
produce a set of deliverables that describes in much more detailed terms
exactly how the system should be built; answers the questions of who will use
the system, what the system will do, and where and when it will be used.
THREE STEPS:
1) An analysis strategy is developed to guide the project team's efforts. Such
a strategy usually includes studying the current system (called the as-is
system) and its problems, and envisioning ways to design a new system
(called the to-be system).
2) The next step is requirements gathering (e.g., through techniques such as
interviews, group workshops, or questionnaires). The analysis of this
information—in conjunction with input from the project sponsor and many
other people—leads to the development of a concept for a new system. The
system concept is explained through a set of requirement statements and a
set of business analysis models that describe how the business will operate if
the new system is developed. The analysis models represent user/system
interactions and the data and processes needed to support the underlying
business process.
,3) The analyses, system concept, requirements, and models are combined
into a document called the system proposal, which is presented to the project
sponsor and other key decision makers (e.g., members of the approval
committee) who will decide whether the project should continue to move
forward.
analysis strategy - correct answer ✔First step in the Analysis Phase (PADI);
An analysis strategy is developed to guide the project team's efforts. Such a
strategy usually includes studying the current system (called the as-is system)
and its problems, and envisioning ways to design a new system (called the to-
be system).
Approval committee - correct answer ✔The system request and feasibility
analysis (Planning Phase) are presented to an information systems approval
committee (sometimes called a steering committee), which decides whether
the project should be undertaken.
Architecture design - correct answer ✔2nd step in the Design Phase (PADI);
describes the hardware, software, and network infrastructure that will be used
for the to-be system.
As-is system - correct answer ✔current system
Break-even Analysis - correct answer ✔one strategy used to determine the
economic feasibility of a project (economic feasibility is part of the Feasibility
study performed in the Planning Phase of the SDLC)
Business analyst - correct answer ✔The business analyst role focuses on
the business issues surrounding the system. This person helps to identify the
business value that the system will create, develops ideas for improving the
business processes, and helps design new business processes and policies.
, The business analyst will have business training and experience, plus
knowledge of analysis and design.
Business Need - correct answer ✔A project is identified when someone in
the organization identifies a business need to build a system. Examples of
business needs include supporting a new marketing campaign, reaching out
to a new type of customer, or improving interactions with suppliers.
Business Process Automation (BPA) - correct answer ✔technology
components are used to complement or substitute manual process.
Business Process Improvement (BPI) - correct answer ✔In many situations,
business process improvement (BPI) results from studying the business
processes, creating new, redesigned processes to improve the process
workflows, and/or utilizing new technologies enabling new process structures.
Business Process Reengineering (BPR) - correct answer ✔complete
revamping of the organization's business processes; BPR projects involve
substantial risk due to the significant organizational and operational changes
that result.
Business Process Management (BPM) - correct answer ✔BPM is a
methodology used by organizations to continuously improve end-to-end
business processes. BPM can be applied to internal organizational processes
and to processes spanning multiple business partners.
Business Requirements - correct answer ✔The business need drives the
high-level business requirements for the system. Business requirements
describe the reasons for developing the system and outline the capabilities it
will provide the organization. These requirements need to be explained at a
high level so that the approval committee and, ultimately, the project team
understand what the business expects from the final product. Business
