Questions
1. What are the major roles played by a systems analyst on a project team?
A system analyst’s role is to:
Identifying how technology can improve business processes
Designing the new business processes
Designing the information system
Ensuring that the system conforms to information systems standards
2. Compare and contrast the role of a systems analyst, business analyst, and
infrastructure analyst.
These three roles emphasize different perspectives on the system. The business
analyst represents the sponsor/users interests, while the systems analyst knows how to
apply IS to support business needs. Together, the systems analyst and the business
analyst can design a system that conforms to the IS standards while adding value to
the business. The infrastructure analyst has more technical knowledge and provides
the team with technical constraints, or identifies infrastructure changes that the new
system will require.
System Analyst: A System Analysts role is to:
Identifying how technology can improve business processes
Designing the new business processes
Designing the information system
Ensuring that the system conforms to information systems standards
Business Analyst: A Business Analyst’s role is to:
Analyzing the key business aspects of the system
Identifying how the system will provide business value
Designing the new business processes and policies
Infrastructure Analyst: The Infrastructure Analyst’s role is to:
Ensuring the system conforms to infrastructure standards
Identifying infrastructure changes needed to support the system

3. Compare and contrast phases, steps, techniques and deliverables.
The Systems Development Life Cycle “SDLC” has a set of four fundamental phases:
planning, analysis, design, and implementation. Different projects may emphasize
different parts of the SDLC or approach the SDLC phases in different ways, but all
projects have elements of these four phases.
Each phase is itself composed of a series of steps, which rely upon techniques that
produce deliverables (specific documents and files that provide understanding about
the project).
Example: When you apply for admission to a university, there are several phases that
all students go through: information gathering, applying, and accepting. Each of these
phases has steps—information gathering includes steps like searching for schools,
requesting information, and reading brochures. Students then use techniques (e.g.,
Internet searching) that can be applied to steps (e.g., requesting information) to create
deliverables (e.g., evaluations of different aspects of universities).
4. Describe the major phases in the SDLC.
There are four major phases in SDLC.
a) Planning: The Planning phase is the fundamental process of understanding
why an information system should be built and determining how the project
team will go about building it.
b) Analysis: The Analysis phase answers the questions of who will use the
system, what the system will do, and where and when it will be used. During
this phase, the project team investigates any current system(s), identifies
improvement opportunities, and develops a concept for the new system.
c) Design: The design phase decides how the system will operate, in terms of the
hardware, software, and network infrastructure; the user interface, forms and
reports; and the specific programs, databases, and files that will be needed.
d) Implementation: The final phase in the SDLC is the implementation phase,
during which the system is actually built (or purchased, in the case of a
packaged software design). This is the phase that usually gets the most
attention, because for most systems it is longest and most expensive single
part of the development process.

5. Which phase in the SDLC is most important? Why?
All systems development projects follow essentially the same fundamental process
called the system development life cycle (SDLC). The planning phase in SDLC is the
most important phase because during this phase the project team identifies the
business value of the system, conducts a feasibility analysis, and plans the project.
This phase is the fundamental process of understanding why an information system
should be built and determining how the project team will go about building it.
6. Describe the principal steps in the planning phase. What are the major
deliverables?
The planning phase is the fundamental process of understanding why an information
system should be built and determining how the project team will go about building
it. It has two steps:
1. Project Initiation: This step involves the identification of the system’s
business value. A system request presents a brief summary of a business need,
and it explains how a system that supports the need will create business value.
The IS department works together with the person or department that
generated the request (called the project sponsor) to conduct a feasibility
analysis. The feasibility analysis examines key aspects of the proposed project
like the technical feasibility, economic feasibility and organizational
feasibility
2. Project Management: Once the project is approved, it enters—project
management. During project management, the project manager creates a work
plan, staffs the project, and puts techniques in place to help the project team
control and direct the project through the entire SDLC. The deliverable for
project management is a project plan that describes how the project team will
go about developing the system.
