The scoping targets over the first 12 months, stated as assumptions rather than promised results: cut defect escape rates (measured in PPM) to directly lower warranty and rework costs, reduce scrap 8-12% by catching defects at the source rather than downstream, and lift throughput yield because lines spend less time on quality holds and rework loops. OEE follows the same mechanism - fewer unplanned quality stops means more scheduled time actually producing. What those percentages translate to in dollars depends on your throughput and current scrap history, which is exactly what the audit weeks quantify before you commit to a build.
The return compounds in months 7-12 as your operators get fluent with the system and the model stabilizes on your product mix. Retraining cycles shorten from weeks to days, accelerating time-to-production for new SKUs and reducing the engineering overhead on line changeovers. The bigger shift is in what your quality team does all day: less standing at inspection stations, more root-cause analysis and supplier quality work - the judgment work you hired them for. By month 18, cumulative scrap and rework savings are scoped to cover the system's cost on your high-volume lines and keep compounding from there - a target we build from your own throughput and margin data, not a benchmark claim.
