Tiivistelmä
The purpose of this thesis is to implement WATS (Test Data Management system) in an electronics production environment in order to improve test data handling and support lean manufacturing goals.
The work involved deploying WATS on a production line, integrating it with existing enterprise systems, and configuring it to capture and analyze test data. Lean tools such as Pareto charts, first-pass yield tracking, and PDCA cycles were applied to identify root causes and improve processes.
As a result, test cycle time was reduced by 12.5%, failure rates dropped by 50%, and first-pass yield increased from 90.2% to 95.1%. These outcomes highlight how centralized test data and real-time analytics can significantly improve product quality and production efficiency.
