Systems analysis
Systems analysis is “the process of studying a procedure or business to identify its goal and purposes and create systems and procedures that will efficiently achieve them”. Another view sees systems analysis as a problem-solving technique that breaks a system down into its component pieces and analyses how well those parts work and interact to accomplish their purpose.
The field of system analysis relates closely to requirements analysis or to operations research. It is also “an explicit formal inquiry carried out to help a decision maker identify a better course of action and make a better decision than they might otherwise have made.”
The terms analysis and synthesis stem from Greek, meaning “to take apart” and “to put together”, respectively. These terms are used in many scientific disciplines, from mathematics and logic to economics and psychology, to denote similar investigative procedures. The analysis is defined as “the procedure by which we break down an intellectual or substantial whole into parts,” while synthesis means “the procedure by which we combine separate elements or components to form a coherent whole.” System analysis researchers apply methodology to the systems involved, forming an overall picture.
System analysis is used in every field where something is developed. Analysis can also be a series of components that perform organic functions together, such as systems engineering. Systems engineering is an interdisciplinary field of engineering that focuses on how complex engineering projects should be designed and managed.
System analysis is a problem-solving process that involves breaking down a system into its components to understand how it works, identify issues, and find improvements. It is used to identify problems, define system goals, and gather requirements for either improving an existing system or developing a new one. This analysis helps ensure that a system functions efficiently and effectively to meet its objectives.

Key aspects of system analysis
- Problem identification: System analysis aims to identify problems, inefficiencies, and areas that need improvement within a system.
- Goal and requirement definition: It involves gathering facts and understanding user needs to define what the system should do, which is essential for either developing a new system or modifying an existing one.
- System breakdown: Analysts break down a complex system into its individual parts to study how they interact and function together.
- Improvement and development: The insights gained from analysis are used to recommend and develop improvements or to design a new system that is more effective, secure, and meets user requirements.
Applications of system analysis
- Improving existing systems: It can be used to analyze and upgrade outdated or problematic systems to make them more efficient or to fix issues.
- Developing new systems: It is a crucial first step in developing new systems to ensure they are built correctly and will function as intended.
- Problem-solving: It serves as a structured method for tackling problems that involve a complex system, regardless of whether it is a computer program, a business process, or a manufacturing operation.
