The scope of requirements changes in Waterfall model is less comparative to the Spiral Model. You progress to the next stage in Waterfall model only when the requirements of the above stages are finalized and signed off. So exactly, we do not have any scope of changing the requirements once we move down the phases in this model.

However, during the life cycle Spiral model gives us flexibility to change the requirements and scope anytime.

In this model, we implement the individual requirements following all the standard phases of Software Life Cycle. If there is any new change in the software we can implement it in the next version of the software.
