A brief guideline for requirements authoring

1. Start by identifying the stakeholders: Understand who the primary and secondary stakeholders are for the project, and gather their input on the requirements. This will help ensure that the requirements align with the needs of the customers and other stakeholders.
2. Define the project goals and objectives: Clearly define the goals and objectives of the project, and ensure that they align with the needs of the stakeholders. This will provide a clear direction for the project and help guide the requirements authoring process.
3. Use a consistent format: Use a consistent format for writing the requirements, such as the SRS (Software Requirements Specification) template. This will help ensure that all requirements are written in a clear and consistent manner, making them easier to understand and implement.
4. Be Specific, Measurable, Achievable, Relevant, and Time-bound (SMART): Make sure that each requirement is Specific, Measurable, Achievable, Relevant and Time-bound. This will help ensure that the requirements are clear, testable and achievable within the given constraints.
5. Use plain language: Use plain language when writing the requirements, avoiding technical jargon and acronyms. This will help ensure that the requirements are easy to understand for all stakeholders.
6. Prioritize the requirements: Prioritize the requirements based on their importance and impact on the project. This will help ensure that the most important requirements are addressed first and that the project stays on track.
7. Validate the requirements: Validate the requirements with the stakeholders, and ensure that they are complete, consistent, and aligned with the project goals and objectives.
8. Keep requirements up-to-date: Keep the requirements up-to-date throughout the project, and make sure that any changes are reviewed and approved by the appropriate stakeholders.
9. Document the requirements: Keep a clear and complete documentation of the requirements, and make sure that they are easily accessible to all stakeholders.
10. Continuously review and improve: Continuously review and improve the requirements authoring process, and make sure that it aligns with the best practices in the industry.

It is important to note that these are general guidelines, and the actual process and format may vary depending on the context and the stakeholders involved. Also, it is important to have a clear process for requirements authoring that should be followed by all stakeholders involved in the development process, and that should be part of the overall requirements management process.
