The systematic discussion of requirements is crucial. This is exactly what we mean by requirements engineering or requirements management: a systematic and disciplined process for specifying and managing requirements.
Requirements engineering is a fundamental phase in the software development process in which the requirements for the software product to be developed are identified, analysed, documented, verified and managed. This process lays the foundation for the entire development cycle and has a great influence on the success of the project.
A thorough requirements analysis makes it possible to understand the needs and expectations of all relevant stakeholders. This understanding forms the basis for developing software that meets the specific needs and desires of the stakeholders.
From requirements documentation to quality control: requirements engineering helps you to develop software that convinces users - regardless of whether you rely on agile methods, the waterfall model or another process model.
