Implementation Strategy and Planning Questions

Covers realistic planning and delivery of solutions across technical, operational, and organizational dimensions. Candidates are evaluated on defining rollout strategies such as pilot deployments, phased rollout, or full release; scoping a minimum viable scope and sequencing features; estimating budgets, personnel needs, and team composition; creating timelines, milestones, and cross functional responsibilities; and identifying dependencies across teams and systems. Includes specifying technical requirements for infrastructure, integrations, customizations versus configurations, performance and scalability, security and compliance, and deployment and rollback approaches. Emphasizes risk identification and mitigation for integration, data migration, operational disruption, and user resistance; contingency and rollback planning; deployment and operational readiness including staffing and training; and monitoring and defining success metrics tied to adoption and business outcomes. Also assesses trade off analysis between speed, quality, and cost, cost estimation and return on investment, communication and change management approaches to drive adoption, and creative problem solving to deliver outcomes within constraints such as limited budget, technology, or compressed schedules.

Explain model drift versus data drift and provide practical methods to detect each in production. Mention statistical tests (K-S, PSI), monitoring windows, use of shadow traffic, and actions you would take upon detection (retrain, degrade functionality, notify stakeholders).

Describe three practical rollback strategies for ML deployments: automatic rollback on KPI regression, manual rollback, and blue-green deployment. For each, list the trigger conditions, rollback steps, pros/cons, and when you would prefer that approach in a financial-services product with regulatory audit requirements.
