Requirement engineering

What is requirements analysis in programming and IT?

Requirements analysis (also referred to as requirements management or requirements elicitation) is an important process in IT and software development. It is the systematic identification, documentation and analysis of requirements for a system or software. The goal of requirements analysis is to understand the needs and expectations of stakeholders (e.g., customers, users, managers, developers) and to derive clear, complete, and consistent requirements from them.

Requirements analysis usually consists of several logical steps:

1. Requirements elicitation: Here, information is gathered from various stakeholders to understand their needs and expectations.
2. Requirements analysis: The collected information is analyzed to identify the actual requirements for the system or software.
3. Requirements documentation: The identified requirements are documented in a structured format to create a common understanding for all stakeholders.
4. Validation and verification of requirements: The documented requirements are reviewed to ensure that they are accurate, complete, and consistent.
5. Requirements management and tracking: Requirements are managed and tracked throughout the development process to ensure they are met in the final solution.

Requirements analysis is critical to the success of an IT project because it helps to clearly define project goals and requirements, reduce the risk of errors and misunderstandings, and increase customer satisfaction.
