A system is a collection of interconnected elements that work together to achieve a specific goal. In the context of a Business Information System (BIS), it is an organized structure that enables the management of business processes through the collection, transmission, and processing of information. The elicitation and analysis of system requirements represents a phase of information systems development. When developing a system, it is necessary to distinguish between functional and non-functional requirements, constraints, and specify all expected system specifications. In system analysis, the most common techniques for eliciting system requirements include interviewing users and relevant stakeholders, organizing workshops with stakeholders, and conducting surveys and observations. The importance of presenting a system prototype during interviews is also mentioned to provide users with a visual and interactive experience and to gather feedback. The analyst's experience can be valuable in documenting past processes and reviewing them to identify benefits and shortcomings for future projects. During the feasibility analysis and prioritization of system requirements, it is crucial to evaluate the project's technical, financial, and operational feasibility in order to determine the priorities of the requirements. This analysis involves evaluating resources, time frames, costs, and potential risks to identify key requirements that will be implemented first. The goal is to ensure that the most important and feasible requirements are met first, while the others are planned and allocated based on available resources.
