What is structured analysis?
Structured analysis is a systems development method used for analyzing and designing information systems. It involves a step-by-step process for understanding, documenting, and designing the various processes, data, and interfaces within a system.
In structured analysis, the system is divided into smaller modules or components, allowing for a detailed analysis of each part separately. The main focus is on understanding the functions and requirements of the system, identifying its inputs, processes, and outputs, and documenting them using various techniques such as data flow diagrams, entity-relationship diagrams, and process specifications.
The objective of structured analysis is to break down a complex system into manageable components, understand the flow of data and processes within the system, and identify the relationships and dependencies between various components. This helps in identifying potential issues and bottlenecks in the system and designing an efficient and effective solution.
Structured analysis provides a systematic approach to analyze and design systems, making it easier to understand and communicate the requirements and specifications of a system to stakeholders, developers, and users. It is often used in combination with other methodologies such as structured design and structured programming to develop high-quality and well-structured information systems.
