Suggested Approach

Start by clarifying the business objective and translating it into a measurable question, then outline a structured plan to collect and analyze data, and finally deliver actionable recommendations with clear next steps. Emphasize iterative stakeholder alignment and hypothesis-driven scoping to manage ambiguity.

Pro tip: Anchor your approach in a specific framework like 'clarify, hypothesize, measure, validate, recommend' and always tie your analysis back to a business metric that matters to Walmart Labs, such as customer lifetime value or conversion rate.

1. Clarify the Problem

Ask targeted questions to understand the business context, stakeholders' goals, and constraints. Define a clear problem statement and success criteria.

2. Define Metrics and Hypotheses

Identify key performance indicators (KPIs) that align with the business objective. Formulate testable hypotheses about what might be driving the problem.

3. Build and Validate Dataset

Determine required data sources, assess data quality, and create a dataset that supports analysis. Clean and transform data as needed.

4. Analyze and Iterate

Perform exploratory analysis, test hypotheses, and validate findings. Iterate with stakeholders to refine scope and ensure alignment.

5. Recommend and Communicate

Synthesize insights into a clear recommendation with actionable steps. Present findings to stakeholders, highlighting impact and next steps.
