Job Title: Senior Data Analyst Company Name: iOPEX Technologies Job Url: https://chatgpt.com/c/698d23c9-016c-832f-b916-8aa954de4818 Job Description: If a senior stakeholder asked for this on Wednesday for a Monday board presentation, I’d treat it as both an analytics and risk-management exercise. Day 1 (Wednesday): Clarify and scope Clarify the decision context How the forecast will be used (scenario planning vs. committed target) Required level of precision Definition of “avoided spend” and what counts as an overpayment Whether a range is acceptable vs. a point estimate Align on output Point estimate + confidence range Key assumptions Sensitivity scenarios I’d communicate early that given data limitations, I’ll provide a defensible estimate with transparent assumptions rather than false precision. Day 2 (Thursday): Build a defensible baseline Assemble the best available proxy dataset Pull historical payment and overpayment records from all relevant systems Reconcile definitions and identify gaps Partner with finance/operations to validate logic Data validation Reconcile totals against financial statements or summaries Quantify missingness and potential bias Document transformation logic Initial analysis Trend historical overpayment rates Identify drivers (volume, policy changes, operational changes) Create a simple baseline projection Day 3 (Friday): Model scenarios Given limited time and imperfect data, I’d prioritize transparent forecasting approaches, such as: Baseline trend extrapolation Scenario modeling (conservative, expected, optimistic) Sensitivity analysis on key drivers (volume, detection rate, intervention impact) I’d quantify uncertainty explicitly (ranges rather than single numbers). Day 4 (Weekend or Monday morning): Synthesize for decision-makers Deliver a concise executive summary: 1. The estimate Range + most likely scenario 2. Key drivers What assumptions matter most 3. Confidence level What is well supported vs. directional 4. Risks & caveats Data gaps and potential variance 5. Next steps How to improve the forecast (data instrumentation, monitoring plan) How I’d communicate I would be explicit: The number is a decision support estimate, not an exact prediction Here’s what would change the forecast Here’s how we’ll track actuals vs. forecast This builds trust and prevents misuse of the number. Why this approach works It balances: Speed (tight timeline) Rigor (validation + scenarios) Transparency (assumptions and uncertainty) Most importantly, it ensures leadership understands both the insight and its limitations, enabling better decisions. If you want, I can condense these into shorter versions for a form with character limits or make them more technical (e.g., specific modeling techniques).
