Campaign Effectiveness Analysis
The founder brief mentions "Campaign Analysis 40%". The meaning of 40% (budget share, uplift threshold, discount level, attribution weight?) is not defined, so it is not applied here. Standard incrementality analysis is used until the rule is supplied.
The scenario and data are provided, but tasks that depend on the undefined business rule are marked and must not be assumed.
Business scenario
Marketing spent heavily on Black Friday and summer sales. Finance asks which campaigns paid back.
Problem statement
Estimate the incremental revenue and gross margin of each campaign against a baseline, net of discount cost and budget.
Learning objectives
- Construct a credible baseline
- Estimate incremental margin, not just revenue
- Detect pull-forward effects
Instructions
Baseline: same days in the prior year scaled by the growth rate of non-campaign weeks, or the 4 weeks before/after excluding other campaigns. Margin = net revenue − unit_cost × quantity. ROI = (incremental margin − budget) ÷ budget.
Tasks
- Daily revenue and margin series with campaign flags.
- Baseline per campaign; incremental revenue and margin.
- Discount cost estimate.
- Post-campaign dip (pull-forward) check.
- ROI table and recommendation for 2026.
