Abstract
The purpose of this article is as an
introduction that helps in better understanding the introduction of Business
System Analysis, this article gather the definition about business system
analysis, system analyst and subjects that related to business system analysis
in order to understand the definition before jump to another deep topics about
business system analysis. This article likely will focus on basic business
analysis and help in understanding why is system involved in business analysis.
I hope this article will help as many students and readers out there in order
to have a better understanding regarding business system analysis and for me,
myself to achieve a good writing in distribute information.

Introduction
Introduction
1.0 What
is business analysis
Business analysis is a research
discipline. According to business analyst experts, the development of business
analysis as a professional discipline has extended the role and
responsibilities of the business analyst (BA). Increasingly, BAs are engaged at
an early point. They investigate ideas and problems, formulate options for a
way forward and produce business cases setting out their conclusions and recommendations.
As a result, the responsibility for advising organizations on effective courses
of action lies with BAs, and their work precedes that of the project manager. (Business Analysis 2nd Ed.,
Debra Paul and Donald Yeates (eds), BCS, 2010).
Business Analysis is the discipline of
identifying business needs and formulating workable solutions to business
problems. The development of business analysis as a profession has extended the
role and responsibilities of the business analyst who now needs the widest
possible array of knowledge, skills and tools to be able to use each when and
where it is needed. (Business Analysis 2nd
Ed., Debra Paul and Donald Yeates (eds), BCS, 2010).
1.1 What is business analyst
In larger organizations, System Analysts make
the communication between IT and Business departments possible, to evaluate a
company’s procedures and systems in order to develop insights into how to make
changes to assist the business in operating more efficiently.
Business analyst refers to any person
who is responsible for performing the business analysis functions for IT system
development projects such as analyzing business needs, facilitating the elicitation
of user requirements, documenting and prioritizing the business requirements, verifying
the major project deliverables, business reengineering opportunities and work flow
from business perspective, and facilitating effective communication between
business and IT sides. (Government of the
Hong Kong Special Administrative Region, March 2015)
“A business analyst works as liaison
among stakeholders in order to elicit, analyze, communicate, and validate
requirements for changes to business processes, policies, and information
systems". The set of tasks and techniques used to :
- . Work as liaison among stakeholders
- . To understand the structure, policies and operations of an organization
- To recommended solutions that enable the organization to achieve its goals

As shown above is an example how
putting business analysts in context. A business context model is needed in
order to express the current business problem and the need to propose goodness
and scope of a project. “The business context model should
identify the actors (people, organisations, systems) who play a significant
role in the business process or in the business domain, and the business areas
of interest relevant to the scope of the work and potential change which may
require exploration and further analysis.” (Suzanne Jane Maxted, The Business
Context Model; As Good As It Gets, 2008)

What is a system?
A perceived whole whose elements ‘hang
together’ because they continually affect each other over time and operate
toward a common purpose. Systems consist of sub-systems or functions,
processes, activities and tasks. Examples of systems can be found everywhere. A
flower is a system, which stays alive through the relationship between the
roots and the stem, the petals and the seeds. A computer is a system, which
operates because the central processing unit, the keyboard and the monitor
‘hang together’, operating toward a common purpose. A car is a system, where
the engine, wheels, and chassis work together to provide a particular means of
transportation. The ocean is a system; fish, mammals, algae coral, and water
continually affect each other and change the nature of the ocean over time. (International Records Management Trust
and International Council On Archives, 2009)
Using system, a responsible group of workers usually do task to determining solutions that usually carried out using software system development or management. The person who carries out this task is called a business analyst or system analyst. According to the International Institute of Business Analysis (IIBA) the role of business analyst or system analyst is a liaison among stakeholders in order to understand the structure, policies, and operations of an organization, and to recommend solutions that enable the organization to achieve its goals.
By definition, business system is to do
things to challenge the current way that an organization works. Business people
do what they can to create project which often contain technical and logical
mistakes. ‘Business analysis’ is a study
of what the business is supposed to do, while ‘systems analysis’ is a study of
the business’ systematic behavior.

3.0 What is Business System Analysis?
3.1
System thinking
Figure
2 : (Tim Joshi, The Next Generation of Business Analysis Methodologies, 2009)
Systems thinking which an
understanding of a system by look the linkages and interactions between the
elements of the system. It is based on the belief that the component parts of a
system that will act differently when isolated from the system's environment or
other parts of the system. System thinking focusing on integrating information
from different sources and different types.
3.2
Moving to systems thinking
These are experts that share the same
view
Michael
Goodman, 2016

“Systems
thinking often involves moving from observing events or data, to identifying
patterns of behavior overtime, to surfacing the underlying structures that
drive those events and patterns.”
“The
whole system is a systems thinking view of the complete organisation in
relation to its environment. It provides a means of understanding, analysing
and talking about the design and construction of the organisation as an
integrated, complex composition of many interconnected systems (human and
non-human) that need to work together for the whole to function successfully.”

Elements of system
Figure
: Systems analysis and design, 2015
Outputs
and Inputs
- . The main aim of a system is to produce an output which is useful for its user.
- Inputs will be the information that enters into system for processing.
- . Output will be the outcome of processing.
Processors
- . The processor is the element of a system that involves the actual transformation of input into output.
- It is the operational component of a system. Processors may modify the input either totally or partially, depending on the output specification.
- . As the output specifications change, so does the processing. In some cases, input is also modified to enable the processor for handling the transformation.
Control
- . The control element guides the system.
- It is the decision–making subsystem that controls the pattern of activities governing input, processing, and output.
- The behavior of a computer System is controlled by the Operating System and software. In order to keep system in balance, what and how much input is needed is determined by Output Specifications.
Feedback
- . Feedback provides the control in a dynamic system.
- Positive feedback is routine in nature that encourages the performance of the system.
- . Negative feedback is informational in nature that provides the controller with information for action.
Environment
- . The environment is the “supersystem” within which an organization operates.
- . It is the source of external elements that strike on the system.
- . It determines how a system must function. For example, vendors and competitors of organization’s environment, may provide constraints that affect the actual performance of the business.
Boundaries
and Interface
- . A system should be defined by its boundaries. Boundaries are the limits that identify its components, processes, and interrelationship when it interfaces with another.
System.
- Each system has boundaries that determine its sphere of influence and control.
- . The knowledge of the boundaries of a given system is crucial in determining the nature of its interface with other systems for successful design.

Conclusion
Conclusion
In a conclusion, business analysis is a research discipline. It is
contribution of experts such business analyst, system analyst. They have their own
rules and responsibilities which are to investigate ideas and problems,
formulate options for a way forward and produce business cases setting out
their conclusions and recommendations.
Business system analysis consists of system, IT technology in
development to investigate ideas and problems. In larger organizations, System
Analysts make the communication between IT and Business departments possible,
to evaluate a company’s procedures and systems in order to develop insights
into how to make changes to assist the business in operating more efficiently.
By using system, there are responsible group of experts, workers do task to
determining solutions using software system development. By generating and investigating information
and data that existed, they can find possible solutions for the organization
and also they can help organization to achieve their goals and objectives.
It is important to know the function of system thinking, to have a system
thinking in order to manage business analysis using system. Systems thinking
which an understanding of a system by look the linkages and interactions
between the elements of the system. It is based on the belief that the
component parts of a system that will act differently when isolated from the
system's environment or other parts of the system. System thinking focused on
integrating information from different sources and different types.
There are important elements in system, which are outputs, inputs,
processors, control and feedback. For output and inputs, the aim of system to
produce an output for its user, and input will be the outcome of processing.
Processors is a hardware or component in computer which is use to transform
input to output. Control is the guide the system, it is to control the
activities input, processing and output. Lastly, feedback provides the control in
a dynamic system. There are two types of feedback which are positive and
negative feedback. Positive feedback encourages the performance of the system,
and negative feedback is to provides the controller information for their actions
to overcome with solutions and possible decision making.
