Structured Problem Solving and Decomposition Questions
Frameworks and practices for framing ambiguous problems, decomposing complexity into tractable components, and designing an investigative plan. Includes problem framing, hypothesis tree and funnel approaches, logical decomposition of metrics and processes, prioritization of diagnostic paths, and communicating a clear problem statement and scope. Emphasis on translating vague business issues into testable questions, mapping metrics to subcomponents, and sequencing investigations based on impact and likelihood.

Design monitoring and alerting for fairness-sensitive metrics across demographic groups. Build a metric tree (e.g., overall accuracy → per-group accuracy, false-positive rates, calibration), define alert thresholds and an escalation policy, and discuss trade-offs between sensitivity (detecting small drifts) and false alarms that waste engineering time.

Create a hypothesis funnel for frequent hallucinations in a generative QA system. Include branches for training data quality, retrieval/knowledge-augmentation failures, prompt templates, model temperature and decoding, and evaluation gaps. For each branch suggest at least one concrete diagnostic test.

You have three diagnostic actions with estimated effort and expected impact: A (low effort, low impact), B (moderate effort, high impact), C (high effort, medium impact). Under a two-day timebox, explain a prioritization approach and pick an execution order. State assumptions and how uncertainty in impact changes your choice.

A binary classifier's false positive rate is rising sharply among a particular user segment. Create a diagnostic plan: list the data slices to compare, metrics to compute (e.g., precision, score distribution), experiments to try (threshold tuning, targeted relabeling, feature importance), and a method to estimate business impact for each potential fix.

You inherited a legacy recommendation model with little documentation and unclear objectives. Outline a 90-day roadmap to align stakeholders, assess model quality, define measurable goals and OKRs, and deliver at least three prioritized improvements. Include milestones, data/metrics you will gather, and who to involve at each stage.
