Macon a productivity improvement

Many of my early projects for Armstrong World Industries were at the Macon Georgia plant. This was and still is the largest ceiling plant in the world, with a capacity of over half a billion square feet of ceiling tiles produced annually.

I was asked to join a team that was going to help the Macon plant return to budget performance by the middle of the year. At the time, I was known and requested for my product flow and team improvement experience. A group of a dozen engineers, scientists, and project managers traveled to the plant for the week to identify the work we could quickly accomplish to improve plant performance and achieve the required budget attainment by the end of the current operating quarter.

The plant is separated into two operating units: board forming and fabrication. My expertise and experience are in fabrication, so that’s where I was assigned.

When we arrived, I told the team I would take a Gemba walk of the total fabrication business unit and share my recommendations by the end of the day. Hunter, an experienced project manager, and Jason, an electrical engineer asked to join me. I was happy to have help.

As we walked the department, we saw and identified many areas of opportunity that would incrementally improve performance, but to get back to budget performance, we needed a bigger win. And then, we found it. There was a line feeding another major line. As it turns out, it was starving the following line, because it couldn’t supply boards fast enough.

We took a deeper look to see what was causing things to run so slowly. I climbed all over the line to get a visual perspective on what was happening. What I saw shocked me. Large rectangular boards were going around at angles and bumping into guides and equipment and causing jams and shutdowns. It shouldn’t be this difficult to run, I thought.

We measured the operating speed of the line and determined 18 boards could get through the line per minute, when the line was actually running, which wasn’t very often, due to jams. The line was capable of running faster, but the technicians had slowed everything down because they couldn’t trust the boards to flow through the line smoothly.

This was our opportunity. We needed to solve the problems on the line to improve the flow and allow the operating speed to be increased to match the line being fed upstream. This was the project we presented to the rest of the team. I believed we could easily gain ten percent productivity on the line, if not more, which would allow the upstream line to produce closer to its budget with the same labor and energy costs. This improvement would be worth a significant percentage of the overall losses we were trying to recoup.

We were assigned some maintenance support for the rest of the week. Using my reliability and board flow approach, we were able to get boards to flow through the line at 22 boards per minute, which was a twenty percent productivity improvement. We locked all settings in, so that we could sustain the performance and not worry about others adjusting things back to the previous conditions.

This project and many others helped the plant beat its budget commitments and continued to build my reputation as a quick problem-solver and board flow expert. Many years later, I still teach board flow and reliability techniques to clients around the world and the results have been extremely positive and satisfying.
