The final check or assessment in the CRISP-DM process that ensures the necessary data for a model will remain available and at what cost is known as the deployment phase.
Step-by-step explanation:
The final check or assessment in the CRISP-DM process that ensures the necessary data for a model will remain available and at what cost is known as the deployment phase. This is the last phase in the CRISP-DM (Cross-Industry Standard Process for Data Mining) methodology, where the model is put into production and the necessary infrastructure is set up to support it. During the deployment phase, considerations such as data availability, cost of infrastructure, and system scalability are addressed to ensure the successful implementation and ongoing operation of the model.
