• Elicitation – Discovering the underlying business need to be addressed and information related to the product and project requirements, often through conversations with stakeholders.
• Analyzing Requirements – Organizing, specifying and modeling the requirements to ensure they are complete.
• Specifying Requirements – Documenting the requirements in a format that can be shared with stakeholders.
