Case description
Significant downtime and scrap occurred during almost all batches in production. The primary cause was identified as waiting time for delivery of new or missing parts, in addition to parts already delivered according to the BOM (Bill of Materials). This resulted in lost capacity, overtime beyond normal working hours, deviations, and worst-case scrap of batches.
Solution
The first step was to identify why new or more parts were being delivered almost every batch than described in the BOM. After interviewing the support team handling the issue, production data from the last 6 months was gathered. Alongside addressing the primary cause, several other issues were identified and a plan for solving them at the root cause was delivered.
Result
A 70% reduction in scrap related to waiting time was achieved, along with a significant increase in OEE (Overall Equipment Effectiveness). This reduction in the need for new or additional parts during planned production saved time in the support areas and eliminated deviations and overtime both in production and the warehouse department.
