Requirements Elicitation and Scoping Questions

This topic covers the end to end practice of clarifying ambiguous problem statements, eliciting and defining functional and non functional requirements, and scoping solutions before design and implementation. Candidates should demonstrate the ability to identify target users and user journeys, conduct stakeholder interviews, ask targeted and probing clarifying questions, surface hidden assumptions and root causes, and convert vague business language into measurable technical and business requirements. They should capture acceptance criteria and success metrics, define key performance indicators, and translate requirements into testable statements and test strategies that map unit, integration, and system tests to requirement risk and priority. The topic includes assessing technical constraints and operational context such as expected scale, throughput and latency requirements, data volume and read write ratios, consistency expectations, real time versus batch processing trade offs, geographic distribution, uptime and availability expectations, security and compliance obligations, and existing system state or migration considerations. It also requires evaluation of non technical constraints including timelines, team capacity, budget, regulatory and operational concerns, and stakeholder priorities. Candidates are expected to synthesize inputs into clear artifacts such as product requirement documents, user stories, prioritized backlogs, acceptance criteria, and concise requirement checklists to guide architecture, estimation, and implementation. Emphasis is placed on scoping and prioritization techniques, distinguishing must have from nice to have features, conducting trade off analysis, proposing incremental or phased approaches, identifying risks and mitigations, and aligning cross functional teams on scope and success measures. Expectations vary by seniority: entry level candidates should reliably ask core clarifying questions and avoid solving the wrong problem, while senior and staff candidates should rapidly prioritize requirements, anticipate critical non functional needs, align solutions to business impact, and communicate trade offs and timelines to stakeholders.

Compare real-time personalization versus batch processing for a user base of 50M users/day. Define decision criteria (business latency needs, data freshness, cost, engineering complexity), provide rough cost/throughput and latency implications for each approach, and propose a hybrid architecture that balances freshness, cost, and complexity.

Explain the difference between functional and non-functional requirements in the context of an ML product. Provide three concrete examples of each for a fraud detection model (e.g., model scoring behavior, latency SLO, auditability), explain why each example matters for scoping, and how it affects implementation choices.

List five common hidden assumptions stakeholders make when they request 'real-time scoring' from a model. For each assumption explain its possible impact on scope, cost, or design—for example, differing interpretations of 'real-time' latency, data availability at request time, or expectations about stateful features.

You are told to provide weekly churn predictions but your event stream is hourly. List the timing and latency clarifying questions you would ask before designing the pipeline: label availability, training frequency, acceptable prediction latency, backfill strategy for missing data, and how to handle late-arriving labels or re-labeling.

Write three clear, testable acceptance criteria for an image-classification model intended to detect defects in a manufacturing line. For each criterion include: the metric, threshold or pass/fail rule, required test dataset characteristics (e.g., distribution or edge cases), and any latency or resource constraints for inference.
