4. • Many organizations consider information systems and computer
applications as essential to their ability to compete or gain
competitive advantage.
• Information has become a management resource equal in importance
to property, facilities, employees, and capital.
• All workers need to participate in the development of these systems
and applications
• But one specialist plays a special role in systems and applications
development, the systems analyst.
• A systems analyst(s) facilitates the development of information
systems and computer applications.
The Systems Analyst - A Key Resource

5. Systems
Analysts as a
Facilitator

6. • The systems analyst performs systems analysis and
design.
• Systems analysis is the study of a business problem domain
for the purpose of recommending improvements and
specifying the business requirements for the solution.
• Systems design is the specification or construction of a
technical, computer-based solution for the business
requirements identified in a systems analysis. (Note:
Increasingly, the design takes the form of a working
prototype.).
The Systems Analyst - A Key Resource

7. • The system analyst bridges the communications gap
between those who need the computer and those who
understand the technology.
Why do businesses need Systems Analysts?

8. • Systems analysts are people who understand both business
and computing.
• Systems analysts study business problems and opportunities
and then transform business and information requirements of
the business into the computer-based information systems
and computer applications that are implemented by various
technical specialists including computer programmers.
What is a Systems Analysts?

9. A formal definition:
• A systems analyst facilitates the study of the problems and needs of a
business to determine how the business system and information
technology can be solve the problem and accomplish improvements for
the business.
• The product of this activity may be improved business processes,
improved information systems, or new or improved computer
applications frequently all three.
What is a Systems Analysts?

10. • When information technology is used, the systems analyst is
responsible for:
• the efficient capture of data from its business source
• the flow of that data to the computer
• the processing and storage of that data by the computer
• the flow of useful and timely information back to the business and its people
• Information technology is a contemporary term that describes the
combination of computer technology (hardware and software) with
telecommunications technology (data, image, and voice networks).
What is a Systems Analysts?

11. • A systems analyst is a business problem solver.
• A systems analyst helps the business by solving its problems using
system concepts and information technology.
• A systems analyst sell business management and computer
users the services of information technology.
• A systems analyst sells change.
What is a Systems Analysts?

12. • The role of systems analyst is changing into two different
positions or roles, business analyst and application analyst.
• A business analyst is a systems analyst that specializes in business
problem analysis and technology-independent requirements analysis.
• An application analyst is a systems analyst that specializes in
application design and technology-dependent aspects of development.
A synonym is system or application architect.
What is a Systems Analysts?

13. • A system analyst is a system-oriented problem solver.
• System problem solving is the act of studying a problem environment in
order to implement corrective solutions that take the form of new or
improved systems.
• Most systems analysts use some variation of a system problem
solving approach called a system development life cycle.
• A systems development life cycle (SDLC) is a systematic and orderly
approach to solving system problems.
What Does a Systems Analysts do?

14. • The SDLC usually incorporates the following general-purpose problem
solving steps:
• Planning - identify the scope and boundary of the problem, and plan the
development strategy and goals.
• Analysis - study and analyze the problems, causes, and effects. Then, identify
and analyze the requirements that must be fulfilled by any successful solution.
• Design - if necessary, design the solution not all solutions require design.
• Implementation - implement the solution.
• Support - analyze the implemented solution, refine the design, and implement
improvements to the solution. Different support situations can thread back
into the previous steps.

A System Development Life Cycle

16. • System analysts are responsible for other aspects of a system
including:
• PEOPLE, including managers, users, and other developers – and
including the organizational behaviors and politics that occur when
people interact with one another.
• DATA, including capture, validation, organization, storage, and usage.
• PROCESSES, both automated and manual, that combine to process data
and produce information.
• INTERFACES, both to other systems and applications, as well to the
actual users (e.g., reports and display screens).
• NETWORKS, which effectively distribute data, processes, and
information to the people.
What Does a Systems Analysts do?

17. • Systems analysts can be found in most businesses; however,
the organization of information services in many businesses is
in turmoil as those businesses reorganize to improve service,
quality, and value.
