Question

Task Prioritization and Coworker Response Simulation (Data Scientist)

Context

You are a Data Scientist supporting a high-traffic e-commerce recommendations team during a busy week. Multiple stakeholders have requested work with overlapping timelines. Apply a clear prioritization framework, make trade-offs explicit, and communicate using Amazon Leadership Principles (e.g., Customer Obsession, Ownership, Bias for Action, Dive Deep, Deliver Results, Earn Trust, Invent and Simplify, Insist on the Highest Standards).

Tasks

Assume the following five tasks are on your plate today. Each task includes impact, urgency, and effort estimates.

Production Incident: Stale Recommendations

Issue: A feature pipeline lag is causing stale recommendations for ~5% of customer sessions since 06:00 UTC today.
Impact: Estimated revenue impact ~$150k/day; SLA defines this as P1 if >2% sessions affected.
Effort: 2 hours to diagnose + 4 hours to patch; coordination with data engineering on-call.
Risk/Dependency: May affect experiment data quality if not resolved.

VP Ad-Hoc Analysis: Prime Day Funnel Attribution

Ask: Provide an EOD tomorrow readout for a press briefing; target accuracy ±2%.
Effort: ~1 day once data is available.
Dependency: Relies on event logs that have a known ~24-hour delay; potential data availability risk.
Visibility: High; VP and PR review.

Experiment Design and Launch: Homepage Ranking Model

Ask: Finalize guardrails and monitoring; launch is scheduled for today. Marketing has an email queued.
Impact: Expected +0.5–1.0% CTR uplift; delays push campaign a week.
Effort: ~3 hours to complete checklist/guardrails and configure monitoring.
Risk: Launching without guardrails risks customer experience and invalid results.

Quarterly Model Retraining and Bias Audit (Compliance)

Deadline: Due in 3 days; compute window reserved for tomorrow.
Effort: ~2 days (retraining, fairness metrics, documentation).
Risk: Missing deadline breaches policy and may lose compute slot.

Weekly Business Review (WBR) Metrics Refresh

Ask: Validate an anomaly in returns metric and update tomorrow’s memo.
Effort: 1–2 hours.
Visibility: Director-level; informs weekly decisions.
Risk: Decisions made on incorrect metrics.

Coworker Message (Transcript)

Product Manager: "Hey, I’m worried the homepage experiment might slip again. Marketing is on my case. Last time data science asked for more guardrails and it delayed launch. Can we please just launch as planned today? We need momentum and the VP will be checking."

Your Tasks

A) Prioritization and Plan

Rank tasks (1)–(5) from highest to lowest priority.
Provide a brief, time-bound plan for the next 24–72 hours.
Justify your ranking using customer impact, urgency, risk, effort, dependencies, and Leadership Principles.

B) Coworker Communication

Draft the 2–3 minute spoken response you would give to the PM to address their concerns.
Demonstrate empathy, ownership, clarity on trade-offs, and propose a solution path.

What Good Looks Like

Clear prioritization framework (e.g., classify P0/P1 incidents before ROI scoring; consider urgency, impact, effort, dependencies).
Explicit trade-offs and risk mitigation.
Communication that shows Customer Obsession, Ownership, Bias for Action, Earn Trust, and Deliver Results.
