The challenge

Harrow had grown by acquisition to 14 plants on four different ERP instances. Group gross margin had fallen 6.8 points in three years, but no two plants defined cost of goods the same way, so the board could not tell whether the problem was pricing, mix, yield or procurement. Plant managers each had a credible explanation and none of them agreed.

Our solution

We built a common cost model and pulled 26 months of transaction-level data out of all four ERPs into a single warehouse with plant-level reconciliation to the statutory accounts. Process mining on production and procurement events isolated the actual drivers: unplanned changeovers accounted for 2.9 points, off-contract spot purchasing 1.8, and scrap concentrated in three product families a further 1.5. We then ran a 16-week improvement programme on the top three drivers with plant teams owning the interventions.

The results

6.2 of the 6.8 lost margin points recovered within four quarters — $31m annualised. Changeover time down 34% through scheduling changes alone, with no capital spend. Off-contract spend reduced from 22% to 6% of category value. The cost model and warehouse remain in use as the group's monthly reporting spine.
