During which process phase is the Prioritised Requirements List baselined?

The Prioritised Requirements List (PRL) is baselined during the Foundations phase. This phase is critical for establishing a clear understanding of the requirements and priorities before the development work begins. Baselining the PRL ensures that there is a formal agreement on the scope and priorities of the requirements, which serves as a foundation for subsequent development iterations.
