Process Optimization and Bottleneck Resolution Questions

Practical methods for improving process throughput quality and cost by removing bottlenecks and optimizing workflow design. Candidates should demonstrate the ability to identify slow steps capacity constraints and rework loops, analyze queues and resource utilization, propose targeted changes such as parallelization automation or resource leveling, and evaluate trade offs between speed quality and compliance. Coverage includes prioritization frameworks impact and effort analysis pilot experiments rollback planning vendor and tool selection, measurement with metrics such as cycle time lead time throughput and error rate, and distinguishing quick mitigations from systemic redesigns while considering system dependencies and unintended consequences.

Technical (SQL): You have an events table recording process steps for orders: events(order_id, step_name, event_time, actor_id). Write an ANSI SQL query (PostgreSQL-compatible) to compute per-order cycle time (time between first and last event), average cycle time per day, and the count of orders with cycle time > 48 hours. Explain how you'd handle missing timestamps or orders with only a single event.

Problem-solving case: You must choose between three improvement options: A) reduce cycle time by 30% with moderate capital cost, B) reduce error rate by 50% with high recurring cost, or C) increase capacity by 20% through hiring. Outline an analytical approach using expected value and scenario simulation to choose one. Show example calculations using assumed numbers, perform sensitivity analysis on key assumptions, and explain how non-financial factors (regulatory risk, customer trust) would influence the final recommendation.

Problem-solving: Describe a robust rollback plan for a process change that spans multiple systems (CRM, ERP, WMS). Include concrete trigger conditions for rollback (metrics and thresholds), data reconciliation steps, communication plan to stakeholders and customers, and how you would ensure system consistency and data integrity after a rollback.

Scenario: You manage a finance operations team subject to regulatory checks and senior leaders ask for 20% faster throughput. Explain how you'd evaluate trade-offs between speed, quality, and compliance. Propose measurable guardrails, sampling strategies, and control points to pursue speed improvements without increasing regulatory risk.

Explain how you would conduct root-cause analysis (RCA) for a recurring delay in a claims processing workflow. Describe the data analysis steps (what timestamp joins, segmentations, or pivots you'd run), qualitative methods (5 Whys, fishbone), who to interview, and how you would validate hypotheses with data before recommending remediation.
