Requirement analysis is a crucial step in the software development life cycle (SDLC) that involves identifying, analyzing, and documenting the requirements for a software system.

Stages or steps involved in requirement analysis:

1. Requirement Elicitation: In this stage, the requirements are gathered from various stakeholders, such as the customers, end-users, domain experts, and business analysts. The requirements can be collected through various techniques, such as interviews, surveys, workshops, and observation.
2. Requirement Analysis: In this stage, the collected requirements are analyzed to identify their feasibility, relevance, completeness, and consistency. The requirements are also prioritized based on their importance and criticality.
3. Requirement Specification: In this stage, the analyzed requirements are documented in a formal and structured manner, using various techniques, such as use cases, user stories, and requirement documents. The requirements are also reviewed by stakeholders for validation and feedback.
4. Requirement Verification and Validation: In this stage, the documented requirements are verified and validated to ensure that they meet the intended objectives, are technically feasible, and can be implemented within the available resources and constraints.
5. Requirement Management: In this stage, the requirements are tracked, traced, and maintained throughout the SDLC. Any changes to the requirements are documented, analyzed, and approved by the relevant stakeholders to ensure that they do not impact the project objectives and quality.

Overall, the requirement analysis stages involve a continuous and iterative process of collecting, analyzing, documenting, and managing the requirements to ensure that the software system meets the intended objectives and satisfies the stakeholders’ needs and expectations.

Analyzing Gathered Requirements:

Analyzing gathered requirements is an essential step in the software development process. It involves examining the requirements that have been gathered from stakeholders, customers, and other sources to ensure that they are clear, complete, and consistent. The following are some steps that can be taken to analyze gathered requirements:

1. Review the requirements: Read through all the requirements carefully to gain an understanding of what is being requested.
2. Identify inconsistencies: Look for any inconsistencies in the requirements, such as conflicting statements or duplicate requests.
3. Determine feasibility: Consider whether the requirements are feasible to implement, taking into account technical constraints, time, and resources.
4. Prioritize requirements: Prioritize the requirements based on their importance to the project and their impact on the final product.
5. Clarify requirements: Contact stakeholders and customers to clarify any requirements that are unclear or ambiguous.
6. Identify missing requirements: Look for any requirements that have not been identified or documented and determine if they are necessary.
7. Document analysis: Document the results of the analysis and ensure that all stakeholders are aware of any changes or updates to the requirements.

By taking these steps, the analysis of gathered requirements can help to ensure that the project is on track and that all stakeholders are aware of what is required to achieve the desired outcome.

Documenting Analyzed Requirements:

Once the requirements have been analyzed, it is important to document the results of the analysis to ensure that all stakeholders are aware of the requirements and any changes that have been made to them. The following are some tips on how to document analyzed requirements:

1. Create a requirements document: Create a document that lists all of the analyzed requirements, including any changes or updates that have been made.
2. Organize the document: Organize the document in a clear and concise manner, using headings and subheadings to group related requirements together.
3. Include details: Include details about each requirement, such as its priority level, any dependencies, and any constraints or limitations.
4. Use diagrams: Use diagrams or flowcharts to help visualize complex requirements or relationships between requirements.
5. Use clear language: Use clear and concise language when describing the requirements, avoiding technical jargon or ambiguity.
6. Share the document: Share the requirements document with all stakeholders, including developers, testers, and project managers, to ensure that everyone is on the same page.
7. Review and update regularly: Regularly review and update the requirements document throughout the project to ensure that it remains accurate and up-to-date.

By documenting analyzed requirements in a clear and concise manner, stakeholders can more easily understand what is required for the project and work together towards achieving the desired outcome.
