3. Introduction It’s a process of interacting with customers and end-users to find out about the domain requirements, what services the system should provide, and the other constraints . It is a process that involves gathering, researching, defining, structuring, and clarifying the requirements of a product.   As a result of elicitation, a Business Analyst creates a set of project objectives.

4. Techniques for eliciting requirements:

5. The requirements elicitation and analysis has 4 main process:

6. 1.Requirements Discovery It’s the process of interacting with, and gathering the requirements from, the stakeholders about the required system and the existing system (if exists ). 2. Requirements Classification & Organization Putting related requirements together, and decomposing the system into sub-components of related requirements. Then, we define the relationship between these components . 3. Requirements Prioritization & Negotiation This activity is concerned with prioritizing requirements and finding and resolving requirements conflicts through negotiations until you reach a situation where some of the stakeholders can compromise . 4.Requirements Specification It’s the process of writing down the user and system requirements into a document. The requirements should be clear, easy to understand, complete, and consistent.

7.  Requirements elicitation Activities: Requirements elicitation includes the subsequent activities. Few of them are listed below –  Knowledge of the overall area where the systems is applied. The details of the precise customer problem where the system are going to be applied must be understood. Interaction of system with external requirements. Detailed investigation of user needs. Define the constraints for system development.

8. Problems of Elicitation and Analysis Getting all, and only, the right people involved. Stakeholders often don't know what they want Stakeholders express requirements in their terms. Stakeholders may have conflicting requirements. Requirement change during the analysis process.

9. Solutions to Overcome Challenges in Eliciting Requirements: Maintaining proper documentation. Trying to understand from a stakeholder’s perspective. Establishing proper communication with stakeholders. Identifying conflicting requirements from the stakeholder side. Establishing structured and insightful discussions with end-users. Performing proper market research and competitor analysis.
