Suggested Approach

Start by clarifying the goal and constraints, then outline a structured process: identify high-potential promotion candidates using data, design a test with clear success metrics, and iterate based on results. Emphasize cross-functional collaboration and a test-and-learn mindset to drive sustainable revenue growth.

Pro tip: Focus on incrementality rather than total sales—measure lift against a control group to avoid attributing baseline sales to the promotion. Also, consider the long-term impact on customer behavior and margin, not just short-term revenue.

1. Define Objectives and Constraints

Clarify the specific revenue goal (e.g., increase in-store revenue by X%), timeline, budget, and any operational constraints (e.g., inventory, staffing). Align with stakeholders on what success looks like.

2. Identify Promotion Candidates

Analyze historical sales data, customer segments, and product margins to select items with high potential for incremental lift. Consider factors like seasonality, complementarity, and price elasticity.

3. Design the Experiment

Choose a test design (e.g., A/B test at store level), define control and treatment groups, select success metrics (e.g., incremental revenue, units per transaction, margin), and determine sample size and duration.

4. Execute and Monitor

Launch the promotion, monitor key metrics in real-time, and ensure operational execution (e.g., signage, inventory). Address any issues promptly and maintain data integrity.

5. Analyze Results and Scale

Compare treatment vs. control to measure incremental impact. If successful, scale to more stores; if not, iterate on the promotion design. Document learnings for future tests.

Key Points to Mention

  • Incrementality measurement using control groups to isolate promotion impact
  • Selection criteria for promotion: high-margin, popular items with elastic demand
  • A/B testing methodology: randomization, sample size, statistical significance
  • Cross-functional collaboration with marketing, merchandising, and store operations
  • Consideration of long-term effects: customer retention, brand perception, and margin impact
  • Use of data to iterate and optimize promotions over time
