Campaign Scrap Reduction (Before vs. After): Definition, Formula, and Industry Benchmarks
A measurement of scrap rate change between a defined baseline period and a post-campaign period, used to quantify the impact of a quality improvement initiative. Pareto Base' campaign management featu…
Well-scoped scrap reduction campaigns — targeting the top Pareto contributor — typically achieve 20–40% reductions in the targeted defect category within 90 days. Pareto Base campaign tracking lets teams measure this without any manual data extraction.
How to Calculate Campaign Scrap Reduction (Before vs. After)
Formula
Scrap Reduction (%) = ((Baseline Scrap Rate − Post-Campaign Scrap Rate) / Baseline Scrap Rate) × 100
Step-by-Step Example
Baseline scrap rate: 6.2%. Post-campaign scrap rate: 4.1%. Reduction = ((6.2 − 4.1) / 6.2) × 100 = 33.9% improvement. On a 10,000-unit/month line, that's 210 fewer scrapped units per month.

What Campaign Scrap Reduction (Before vs. After) Means for Your Team
For Quality Managers
Campaign results are the evidence you need to demonstrate ROI on quality initiatives. Pareto Base gives you a before-and-after comparison for each campaign — campaign duration, baseline rate, current rate, and percent improvement — all in one view.
For CI & Lean Teams
Campaigns are how you structure your CI work. Define the focus area (product, defect category), set the baseline, launch the campaign, and Pareto Base tracks whether your corrective actions are actually moving the needle.
For Plant Managers
You invested in a quality improvement initiative. Pareto Base tells you whether it worked — in units, percentage points, and eventually dollars when cost tracking is enabled.
For Production Teams
When the quality team runs a campaign targeting the top defect on your line, you see the results in your daily log. If the count goes down, the campaign is working.
The spreadsheet problem with Campaign Scrap Reduction (Before vs. After)
Without a purpose-built campaign tracking tool, before-and-after comparisons require manually comparing two different time-slice pivot tables — typically a weekend project for the CI lead, not a daily view.
