Building Downtime Resilience with a Buffer Station

Note: specific figures, part numbers, and company details have been generalized or removed due to confidentiality.

Background

The line in question had been running for close to a decade: a high-volume machining and assembly operation feeding a major automotive transmission program, running close to around the clock, six days a week.

Role: Project Engineer, leading a cross-functional team of about 10 Duration: 6 months Stakeholders: Plant Operating Committee, Quality, Maintenance, Automation, Production, Accounting

The problem

The line ran with essentially zero buffer between machining and final gauging. Any downstream failure propagated immediately upstream, and healthy machines sat idle waiting on a problem they had nothing to do with. With a 24/7, six-day operating schedule, there was no planned downtime window to install new equipment. Any changeover had to happen without stopping production, or during the one long-weekend shutdown available that quarter.

Approach

• RAID log and risk register. Installation risks, assumptions, and dependencies got logged from day one, since the plan had to work on the first attempt.
• Contingency planning at the design stage. When the primary installation plan ran into an issue during the long-weekend shutdown, a fallback (a temporary hydraulic cylinder mount, run under a documented safety alert) kept the line operational until the next available window.
• Troubleshooting under pressure. Resolving the issue required isolating a fault that wasn’t immediately obvious from the equipment’s wiring, then correcting it to match the design intent.
• RACI matrix across Engineering, Quality, Maintenance, Automation, Production, and Accounting, so a fast-moving weekend cutover didn’t stall on unclear ownership.

Tools used

MS Project, Excel

Outcome

A functioning buffer between machining and gauging, installed without unplanned downtime, giving Maintenance a real window to work on upstream machines instead of chasing every failure live.

What could have been done better

Time constraints forced a lot of fabrication and installation into a single day. Running this during a planned winter or summer shutdown would have given the team more time to install and verify the modifications and train operators on the changes. Doing as much of the fabrication and modification work off the line ahead of time, rather than during the install window, would also have helped.
