01 · Long-standing defect improvement
From a recurring defect to a lasting improvement.
My role · Engineering project lead
A manufacturing defect had resisted years of troubleshooting. Earlier actions had not produced a lasting result, and travel restrictions made collaboration across sites even harder. I led the engineering team responsible for understanding the problem and turning its findings into a sustainable improvement.
Before changing the process, we had to make sure we were solving the right problem.
Understand the problem
I enjoy root cause analysis: understanding why a problem occurs, then asking what would prevent it from returning. I consider individual actions and the wider system. In this case, we separated process variation from measurement error. We mapped possible causes into a hypothesis tree and planned how to test each one, using data, process knowledge, and experiments. That clearer understanding gave us a stronger basis for deciding what to change.
Reduce the noise
Objective information gives people a common basis for decisions and communication. I plan changes carefully, checking risks before acting on a running line. In this project, we turned verified findings into standard procedures, helped teams return to a shared operating standard, and monitored key process inputs and defect results. I value documentation as a living system: focused on what people need, practical to use and maintain, and updated as the work changes.
Improve together
With onsite support restricted, I used remote workshops and shared reviews to align teams on the evidence, risks, and priorities. We adapted deployment to local constraints and connected onsite teams with remote experts. I seek solutions that benefit everyone involved by understanding different perspectives and finding shared goals across functions. Trust and enthusiasm guide how I build that cooperation. Shared ownership helped us keep improving across sites.
What changed
The team improved defect performance across multiple sites and sustained the new baseline beyond the immediate recovery. The work created a repeatable control and improvement system for future challenges.
What I enjoy in technical management and team leadership is helping people turn evidence into lasting improvement.
