Which phase determines if the model meets business requirements?

• A. Evaluation
• B. Deployment
• C. Monitoring
• D. Data Understanding

Answer: (A)

The main idea being tested is determining whether a model satisfies business requirements through an explicit evaluation of its outcomes against those requirements. In the evaluation phase, you measure the model using metrics that reflect real business goals and acceptance criteria set by stakeholders, such as acceptable error rates, latency, cost, fairness, and risk, rather than just technical performance. This phase involves using hold-out or test data, scenario testing, and possibly real-world simulations to see if the model’s results meet the defined success criteria and to decide whether it’s ready to deploy or needs further refinement. If the model doesn’t meet the business needs, evaluation informs what adjustments are needed—more data, different features, or a revised approach—before moving forward. Deployment is about putting the model into production, while monitoring checks performance after deployment, and data understanding focuses on what data is available and relevant.
