Computer systems programming has evolved over time, with software requirements being a major challenge. Software engineering was introduced to address this issue, focusing on requirements, design, coding, and testing. One key aspect is software requirements elicitation, which involves understanding user needs. Concept of operations (ConOps) analysis and document play a crucial role in this process, helping users and developers clarify requirements and improve communication. ConOps serve as a bridge between user needs and system development, aiding in the overall software development process.
