In the CRISP-DM cycle, the phase that follows modelling in the diagram's forward order is:

Answer

Evaluation — does the model answer the business question?

Options - A. Evaluation — does the model answer the business question? - B. Deployment — the model is finished, so hand it over - C. Data preparation — every model must be rebuilt on cleaner data - D. Business understanding — the question is revisited after each model Why - A. Correct — modelling → evaluation. The model is judged against the business success criterion before anything is deployed. - B. This skips a phase. Deployment comes after evaluation; a model that has not been evaluated against the business question is not ready to hand over. - C. Modelling → preparation is the backward arrow, taken when the model reveals a missing column — not the forward order, and not something every model needs. - D. Business understanding is where evaluation can send you if the result would not change the decision; it is not the phase after modelling.
