System Analysis
It is the very first step in any system development and the critical phase where developers come together to understand the problem, needs, and objectives of the project.
Some of the key aspects of system analysis are:
- Problem Identification: It involves identifying the issues that the system is aiming to address. Whether it is automating a business process, improving data management, or improving the user experience, understanding the problem is the first and most important step.
- Requirements Gathering: Once the problem is identified, the next step is to gather and write down the requirements. This involves communicating with the customer and developer to gather information about how the system is to be designed.
- Feasibility study: Before going into development, it is important to check the feasibility of the project. This includes the evaluation of technical, operational, and financial aspects to determine the feasibility of the proposed solution.
- Analysis and modeling: To get a deep insight into the system, analysts develop various models, such as Data Flow Diagrams(DFD), Use Cases, and Entity-Relationship(ER) diagrams. These models help the customer to visualize the system and its interactions.
- Scope Definition: Defining the scope of the system is important to prevent adding excessive features to the system and ensure that the project stays within its limits. It identifies what is part of the system and what is not.
Example:
Fraud Detection Systems: Studying transaction patterns and inconsistencies in financial data to develop algorithms for detecting and preventing fraudulent activities.
System Analysis | System Design
In the areas of science, information technology, and knowledge, the difficulty of systems is of much importance. As systems became more complicated, the traditional method of problem-solving became inefficient. System analysis is to examine a business problem, identify its objectives and requirements, and then design the most optimal solution to fulfill those needs.
