Under the CRISP-DM process for data analysis, if your evaluation of a model shows that the model is not useful, you should return to the ___________ step.

• A. Evaluation
• B. Business Understanding
• C. Data Preparation
• D. Modeling

Answer: (B)

When evaluation shows the model isn’t useful, you go back to Business Understanding. This step is where you redefine what problem you’re solving, what success looks like, and what constraints apply. If the objectives or metrics were mis-specified, revisiting them helps ensure subsequent data understanding, preparation, and modeling efforts align with real business goals. Once the business understanding is clarified, you can adjust data collection and preparation or try a different modeling approach to meet those goals.
