The role-defined, open-ended analysis prompt
Tell it who it is, what the data is, what the three analyses are called, and who the recommendations are for. Then wait five minutes.
Prompt pattern: role ('you are an expert in data analysis'), goal ('uncover insights from this dataset'), the vocabulary ('univariate, bivariate and multivariate analysis, relationships between variables'), the deliverable ('recommendations and insights to the team'), optional framing ('solve this as an assignment'). Context tells the model why it is doing this. Opus was chosen for capability; runtime ~4-5 minutes. Result: executive summary with KPIs, an 'expedited delivery crisis' (67% of customers chose expedited, 0% delivered), platform insights (Meesho AOV ~708, Amazon volume, Myntra cancellations), category and geography, strategic recommendations. ChatGPT with the same prompt: data dictionary first, plain-text steps, Python.
The vocabulary from lessons 2-7 is what makes this prompt work.
