Get it Right Early, the Rest will take Care of Itself

I’d been running reliability and center lining events across the country, and it never ceased to amaze me how small adjustments like leveling rollers, aligning equipment, straightening processes, could transform an entire line. We were seeing 90% fewer jams, 20% higher yields, 40% productivity gains, and a massive boost in team ownership. It was life-changing.

I decided to convince another client to try this approach in his composite decking factory. While the product was thicker and more stable than others I’d worked with, I knew the principles would still apply.

When I reviewed the concept with my sponsor, he admitted they were battling jams that caused serious disruption. He immediately invited me to run a reliability Kaizen on a key production line.

At first glance, the line seemed simple: straight path, thick product. But once we dug in, the misalignment was obvious. Early in the process, a set of rollers fed stabilizing sheets into melted vinyl. The roller system was out of level, causing tension and stress at the mixing point. Once corrected, the sheets fed evenly, drastically improving flow.

Next, we tackled the water bath where the decking was formed. The “carrier” that transported product through the bath was tilted. That misalignment made the material rise or fall, throwing off the next equipment in the line and potentially causing jams.

We built custom brackets using materials on hand to support the carrier at the precise height and alignment. Then we created easy-to-use visuals to ensure it could be consistently set up.

Once everything was lined up and squared off, we started up the line. It ran beautifully. From that stable foundation, we aligned every piece of downstream equipment. The results? Significant productivity gains, reduced safety risks, and a team that now applies the method to other lines in the plant.

When you take the time to get it right early in the process, everything becomes easier downstream. In reliability Kaizen, precision builds momentum and momentum builds belief.

Don’t Judge a Book by its Cover

For part of my career, I worked for Dal-Tile in Dallas Texas. I was the environmental, safety, health, and mining liaison for our twelve manufacturing plants. My job was to help each plant stay compliant and safe, providing training and reporting support. We had a number of factories in Texas, and I visited each one and get to the know the employees and leadership. That way, I could develop a support plan that was mutually beneficial.

We had a plant in Coleman Texas. If you look on the map, you probably won’t find it. It was kind of like driving into the middle of nowhere, taking a left, and then going another 90 miles to get there. So, that’s what I did. When I got close, I exited the highway and spent the final few miles driving on gravel roads through the middle of the town. I wasn’t optimistic I would find a factory in good shape. As I drove up to the tin building, I was wondering how this could be where they made ceramic tile.

I parked and walked into what I thought would be a nightmare scenario: broken down equipment, unhappy employees, and a poor management/worker relationship. I was wrong. When I entered the facility, it was bright, clean, and people were working safely and efficiently.

The equipment looked brand new. That is, except for one enormous clay mixer. It looked like it had been installed during the Stagecoach era. Turns out, I wasn’t far off. It was installed in 1896. I had never seen equipment that old in use in any of the hundreds of factories I had visited over the years. I had seen new equipment operate as if it was installed in the 1800’s, however.

After meeting the leadership team and touring the plant, I had to ask a question that was gnawing at me. Why was every other piece of equipment new and shiny, except for the mixer? Matt, the plant manager told me, “Adam, this mixer has been in operation for 100 years. It never breaks down, requires very little maintenance, and is easy to use. Newer mixers aren’t built to last and are prone to breakdowns.”

This made sense to me. Instead of looking for something shiny and new, we should support and nurture the things that are precious to us. This mixer was the heartbeat of the facility and as such, it was treated with extra care and respected for the service it provided to the process, employees, and customers of Dal-Tile.

I doubt there are any spare parts for the mixer, but based on what I saw, it’s probably still running to this day.

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.

Guiding Principles – Let Your Conscience Be Your Guide

During my career at Armstrong World Industries, I honed my kaizen approach and spent more travel time at the Macon, Georgia plant than at any other location. That’s why I have so many stories to share about my time there.

In another story, I talked about being called the “Conveyer Whisperer.” I was always looking at board flow around the miles of conveyers that snaked through our factories and trying to figure out how to improve flow and reduce jams.

I was invited to the Macon plant to try my hand on the busiest line at the world’s largest ceiling tile plant. I met David, the Business Unit Manager, and he showed me the areas he thought were causing the most downtime and jams on his line.

As I watched boards go around the line, I noticed many conveyer guides “pinching” the boards and sending them in places and at angles that were the root cause of the downtime and jams in my opinion. I shared my thoughts and improvement ideas with David. He didn’t agree. He bet me that my suggested changes to the guides and conveyers would make things worse.

Challenge accepted! I took his bet and proposed an experiment. I would take a small section of the line and make various changes to the guides and squareness of the conveyer. If my methods didn’t work, he could send me home to corporate on the next available flight. If my method worked, he had to let me continue and use necessary downtime to make changes to the rest of the line. He agreed.

David gave assigned a team of operators and mechanics to me. They were interested in what I thought I could do and my approach to the work. They were a bit skeptical that straightening out guides, removing guides, and leveling conveyers would make a difference in the flow around the line, but they were willing. I had to win the bet – I wasn’t ready to go home yet!

We picked our first target area. It was a small section of conveyer, leading to a stacking mechanism. Boards were flowing into guides that looked like “funnels.” Some were getting stuck, and operators were stopping the line to correct the situation and adjusting the guides.

We built a plan to shut the line down for two hours to find the center of the stacking mechanism, make one of the guides parallel to the direction of travel, and remove the guide on the opposite side of the conveyer. We would skew rolls to drive the ceiling tiles to the remaining guide and then allow them to straighten out as they approached the stacker.

We communicated our plans and then shut down and locked out the line for safety. The team got to work and made all the changes. David came out to see what we were doing and poke some fun at me regarding our bet. He told me that my jet to corporate was waiting!

We finished and took our locks off the line. When the line started up, we noticed a significant improvement in the flow of the boards into the stacker. The team was convinced our work helped and started cheering. David came out of his office to see what was going on. His eyes widened. He couldn’t believe what a difference our small changes made. And, we had removed excess equipment from the line, which got in the way of his employees.

David told me that my flight would have to wait. We had to do this work all over the line. For the rest of the week, we did similar work around the line. By week’s end, we had removed more than a dozen guides from the line and everything was flowing better than anyone remembered.

David told me he was disappointed that I didn’t remove more guides from the line and he was willing to have me come back in the future to complete my work. He’d even make my travel arrangements for me.

Moving Mountains … of Paint

During my corporate career at Armstrong World Industries, I gained a reputation for many things: Lean zealot, “Conveyer Whisperer,” and someone who was willing to take on any challenge anywhere I was needed.

One of our lines at the Macon, Georgia plant was experiencing a large amount of downtime and scrap and I was sent to work with a team to resolve the issue. Many other engineers had been working on various improvements on the line with little effect. What did I know that they didn’t?

My first day at the plant, I met with the management team for the production line. They gave me a tour and showed me all the various issues they had been dealing with and how the other improvement projects were not helping.

As I walked around, I spoke with hourly employees who were dealing with these headaches. They were frustrated and seemed on the verge of giving up. When we passed a paint booth, I noticed the ceiling tiles were rotating and vibrating as they were going through the booth on cables.

I asked if this was a normal situation and was assured it was and it wasn’t causing any trouble on the line. It didn’t look right to me. I walked further down the line and sure enough, these turned tiles were causing problems in later processes.

I requested a small team to work with for the next day or so and was assigned a group of experienced hourly technicians. After reviewing principles of flow and conveyer alignment - I was the “conveyer whisperer” after all - we walked through the line and looked for areas that were violating the principles of flow.

We went to the paint booth and saw clear evidence of violations of flow principles. We walked around the booth trying to find what could be causing the trouble. Then we saw it – a “mountain” of paint that had built up on the floor, just after the paint booth. The cables were travelling through and hanging up through the pile of paint. Each cable was being slowed down at a different speed, which caused the boards to rotate and vibrate through the booth.

I asked my team how often the paint build-up was cleaned. They looked at me like I was from Mars. The answer was never. We immediately cleaned the paint build-up, reattached the cable washers (they were designed to spray water on the cables and capture any paint in a drip pan, rather than the floor) that had been disconnected many years before, and then implemented an audit to verify paint booth cleanliness and cable washer operational effectiveness.

Once we did our work, the boards stayed straight and square through the booth, the quality of paint coverage improved, and downtime was greatly reduced. How do you convince a group to change their habits? Show them results, of course.

Saving Is Not Saving

We were building a ceiling tile manufacturing plant in Russia. Like most projects, the engineering team was directed to save money, as long as it didn’t negatively impact safety or productivity. As most were unfamiliar with doing business in Russia, they used their experience with known vendors to acquire equipment for the plant. If there wasn’t enough capacity to fill equipment needs, the project team worked with local consultants to identify the “best” options for equipment purchases.

A few years earlier we had shuttered a plant in Alabama. Equipment was stored in the hopes it might be used for future projects. The project team identified equipment they thought they could use and had it shipped to a contractor, who was responsible to inspect it and bring it up to optimal operating condition. This was done to save more than $1 million for the project.

Two weeks before plant start-up, I traveled to Russia to assess and optimize the flow of ceiling tiles through the new production line. I had done this work many times in other manufacturing plants and was known as the flow “expert”.

When I arrived, I was assigned a team of two mechanics and one production operator. We were going to send ceiling tiles through various parts of the line and make adjustments and corrections where necessary to improve the flow.

Very few tools were available for our use. I packed string, levels, and flat steel bars to help us with the work. Our initial assessment and work through the line went smoothly. We identified conveyers that were out of level, causing the ceiling tiles to skew and jam. Fixing these problems was simple enough. Soon we had tiles flowing smoothly through the first half of the line. Until we reached the equalizer.

The equalizer is a large panel saw. Its purpose is to cut ceiling boards into finished ceiling tiles. The board goes through a first set of saws, strikes a transfer, and then is driven through a second set of saws positioned at a right angle.

Boards were going through the saws at an angle. Instead of tiles looking like rectangles, they looked like trapezoids. They weren’t going to fit into ceiling grid that way.

There were many possible reasons for the angled cuts. After resolving many issues, the tiles still weren’t correct. What was going on? Normally, fixes happen independently of the saw assemblies. Saws are typically located in a level and square way on a frame. Everything else controls how the boards come to the saws in a square or angled fashion.

In this case, the problem was in the saw assembly. We locked out and climbed up on the equipment to take a closer look. The equalizer was freshly painted and made to look as if it was new. But it was far from new. There were many missing or broken parts. Because of that, we couldn’t control the boards as they were being cut. Broken motor mounts caused the saw blades to rotate in an elliptical fashion. How did the contractor miss this critical detail? How did we miss this during equipment inspection?

We spent the rest of our time repairing or replacing broken parts. Some things couldn’t be fixed immediately. We ordered parts and equipment from other locations. Some had to be air-freighted from the United States at considerable cost. All fixes were completed prior to the official plant start-up, but took valuable resources away from other critical work. All of this could have been avoided had the project team recognized the critical influence of the equalizer and chosen to invest in the right tools for the new plant. Expected savings disappeared due to the lack of All Tools Available.

Trust, but Verify

In 2005, I was asked to be part of a team to help Armstrong’s Mobile Alabama ceiling tile plant improve their performance.  Production output had steadily declined over the first few months of the year, and they were well behind budget.  The team was tasked with identifying and implementing improvements to the operation that would drive performance back to budget for the full year. The team leader called the effort a “Full Court Press”, meaning we would not give up until we accomplished our mission.

The Mobile plant had one board forming line and two fabrication and packaging lines. The board forming line was clearly not the problem, as the quality, productivity, and safety were well above budgeted performance. The fabrication and packaging lines were where the losses were occurring, so we agreed to focus our efforts there.

On our first day at Mobile, we attended the morning production meeting. We introduced the team to the staff and reviewed performance. The plant staff members were open to our help, but weren’t sure what we would be able to deliver in a short time. We assured the staff we would do our best and coordinate any efforts through them. Once the meeting ended, we took a tour of the fabrication department. During this tour, we observed many problems and spoke with operators, mechanics, and other staff to get feedback and ideas. Many were disappointed with the performance and hoped we would be able to help them turn things around.

Each of our team members had a specialty. One was interested in the programming used to control the equipment, another was fascinated by the coordination of materials and resources. My area of expertise was flow of materials through the production line. During the tour, I noticed many line-stops and jams. I knew I could provide help.

With the agreement of our team leader, another team member and I took a detailed look at one of the main fabrication lines. This line was led by a technician named Walter. Walter was extremely interested in what we were doing, and asked if he could tour the line with us. We were happy to have him along, as he introduced us to all of the crew members and lent credibility to our efforts. He also appreciated our approach of watching the line carefully to identify the causes of the line-stops and jams.

Something Isn’t Hitting Right

On our tour, we stopped at the punch press to watch its operation. Something didn’t look right to me. The press creates holes in the ceiling tiles which allow air and sound to enter the tile. It’s critical for the ceiling tile to enter and exit the press squarely and centered. Following the press, there’s a gate that stops the tile while the press completes its work. If the tile is angled, the edge of the tile gets damaged when it hits the gate. As I watched the tiles enter and exit the press, I noticed they weren’t exiting the press squarely and hitting the stop-gate at an angle.

I asked the press operator if he was concerned about the tiles hitting the stop gate at an angle. He told us he thought any damage would be cut out later down the line. It looked to me as though the amount of damage wouldn’t cut out completely, but the operator was convinced otherwise. I made notes of what I had seen, and we continued our tour.

Following the press, tiles were being painted and then cut to final size. After the cutting station, tiles went through an inspection station, where two operators were visually checking the quality of each and every one. While we were there, the inspectors were rejecting one-third of the tiles they were inspecting. There was so much scrap being generated they were having a hard time keeping up and had to stop the line many times.

During one line-stop we asked the inspectors what they were seeing. They showed us the broken edges of the tiles. The edges had cracks down the length of the tiles at an angle. They looked just like the angle of the press stop-gate we had seen earlier. I asked the inspectors for a few samples, which they were more than happy to share.

A New Angle on the Situation

We took a walk back to the press with Walter. We showed the press operator the sample ceiling tiles. He was shocked. He didn’t realize the stop-gate was causing so much scrap. He immediately shut the line down to make adjustments.

While the line was down, I asked if I could take a look inside the press to see if there might be a reason the tiles were hitting the gate at an angle. After locking out the press, I took a closer look and was amazed at what I saw. The guide rails in the press were not straight as designed, but curved. These rails were causing the tiles to turn at an angle when they entered the press. All plants had scheduled maintenance to replace press guide rails every six months. When I asked the press operator when the last time the rails had been changed, he didn’t remember, but thought it had been years. I then asked if they had backup press guide rails in their storeroom. Luckily, they did. Even luckier, they were straight.

Setting Things Straight

We replaced the curvy press guide rails with straight ones, and started up the press. Immediately we stopped the press. We were still damaging the edges of the tiles, this time at a different angle. We quickly identified the problem. The stop-gate was angled for the curvy guide rails and had not been adjusted for straight press guide rails. Once we straightened the stop-gate, the edge damage disappeared. After a few handshakes and high fives, we created a monthly press guide rail inspection and a six-month replacement program for this critical component.

During the week, the team made many other quick improvements and planned out other work that helped the Mobile plant return to budgeted performance for the year. If there’s a lesson to be learned from Armstrong’s Mobile plant, it’s to trust your processes, but verify them on a regular basis. Trust alone cannot eliminate inefficiencies or waste from creeping in, but consistent verification can identify these issues quickly so that they can be corrected.

Simpler is Better

Sometimes we make things more complicated than they have to be. When we remove the complexity, things seem to get better. I have learned this lesson many times, but my trip to Macon Georgia proved it to me and my team.

In the late 1990’s, I was often asked to help factories solve productivity issues. As I was new to the manufacture of ceiling tiles, I had much to learn. One of my ways to learn was to spend as much time as possible on the factory floor, observing and talking with the operators and mechanics.

I was visiting the largest ceiling plant in the world in Macon Georgia and asked the plant manager if I could spend a day on the line, observing operations and talking with his people. He seemed surprised by my request, but was open to it and gave me the green light.

I started at the beginning of the fabrication line, where the formed 4-foot by 8-foot panels were loaded, and introduced myself to Joe, who was “feeding” the line. He asked me what I was doing there. I explained I was trying to learn how the line operated and the issues he was dealing with. He seemed amused by this and showed me how he operated the line. After about an hour of observation and discussion, Joe had given me a thorough overview of his area of the line and the problems from his perspective. I thanked him for taking the time with me and then left him to go visit with the next operator on the line, Ruth.

Ruth was intrigued by an engineer (a Yankee, no less) who wanted to know what issues she had to deal with as well. She showed me what happened when boards traveled through her paint booth. She was making constant adjustments to the line and I asked her why. She explained the equipment that measured viscosity of the paint was broken, so she was doing her best to get a consistent paint coating, using her experience and observations. Ruth let me try my hand at adjusting viscosity of the paint, and I realized how difficult it was. After some time, I thanked Ruth for her insight and moved on to the remaining operators on the line.

After a full day of visiting, observing, and discussing the issues on the line, I believed I had a plan to make some improvements. I returned to the main office and reviewed my findings with the plant manager. I asked him if he was willing to assemble a small team of operators, mechanics, and a supervisor to work on the problems I had observed. He was extremely willing and said he would have them ready to work with me the next day and for the rest of the week (4 days). Now, I had to determine what to do with my new team.

At 7 am the next morning, I met my team: 3 operators, two mechanics, and a supervisor. We had a meeting room in the middle of the factory. After getting to know each other, I reviewed my observations from the prior day. Luckily for me, two of the operators on the team were Ruth and Joe, so they had some experience with me and felt comfortable talking with me and the rest of the team members. After talking about what I had seen and reviewing their ideas, we came up with two areas to work on: Cutting boards squarely and applying paint consistently. We decided to work on each issue as a full team, one issue at a time. Our first issue was cutting boards squarely.

It’s Hip to be Square

We walked out to the line and went to the equalizer station to see what was going on. The equalizer was a large table saw that cut the 4-foot by 8-foot boards into 2-foot by 4-foot ceiling tiles. The board travels into the equalizer, gets cut into 2-foot by 8-foot strips, then gets transferred at 90 degrees to the next series of saw blades. They then cut the 8-foot strips into 4-foot tiles.

As we watched, we saw the boards go through the saw blades at an angle. Why was this happening? It turns out there were three upper “hold down” rolls driving the boards through the first pass of blades. These rolls were adjustable for on either side of the conveyor. Operators would make pressure adjustments to the rolls to help drive the boards through the saws. There was no way to tell if they were applying equal pressure to the rolls. The unequal pressure on the boards was forcing them through the saws at an angle. Sometimes, this would cause the boards to be cut to the incorrect size, causing scrap.

There were two hold down rolls at the entrance to the saws and one on the exit of the saws. It seemed the two rolls at the entrance were fighting each other, so we decided to raise one of the rolls. To our amazement, the boards ran more squarely through the saws.

Now, we had to figure out how to apply equal pressure to each side of the boards as they entered and exited the saw blades. After many ideas, we realized that by giving the operator the ability to adjust each side of the rolls, they were almost guaranteed to force the boards through with unequal pressure, unless they knew the exact pressure on each side of the board. Since we didn’t have any gauges to measure this, we had to come up with a simpler solution to ensure equal pressure.

Gravity was the solution to our problem. If we could just use the mass of the roll (approximately 55 lbs.) to roll over the board as it entered and exited the saws, the roll would put equal pressure across the board. There was only one way to test this. We disconnected the adjusting screws on the rolls and allowed the rolls to “float” over the board as it traveled below them and into and out of the saws. Now the board was going through in a perfectly square manner. We decided to remove the adjusting screws completely, so operators wouldn’t have the opportunity to reverse this improvement. We also made sure we communicated our changes to all shifts, so people would understand what we did and why we did it. We were proud of ourselves. Now it was time to figure out how we could help the painting process.

It all depends on your point of view

Paint viscosity is critical on a ceiling tile. If the paint is too viscous (too thick), it will cover up the holes on the surface of the tile and reduce its acoustical absorption. If the paint is not viscous enough (too thin), it won’t achieve the proper coverage and required color. The instrument that was broken, a Brookfield viscometer, is a mechanical device that measures the resistance of the liquid as a rod or disc rotates through the liquid. It wasn’t working, so the paint technicians were using a Zahn cup to measure viscosity. This cup looks like a cylindrical ladle with a hole in the center. It is dipped into the liquid and the time it takes for the liquid to totally exit is measured in seconds. The longer the time it takes, the thicker the liquid.

The technicians were taught to observe the bottom of the Zahn cup from the outside. When paint was no longer flowing out of the cup, they recorded the time and then compared it to a chart to assess viscosity. The problem was that as the last bit of paint came out, there were drips, and each operator measured the time differently, leading to variations in viscosity measurements and adjustments. This was leading to problems in the paint booth. We had to find a way to consistently measure the time.

After much trial and error, we realized that we were all looking at the cup incorrectly. If we looked inside the cup, we saw the paint exit in the same way. The moment paint had fully exited the cup, there was a hole that appeared in the center of the cup. Using this method, we were able to consistently measure the time from person to person. It was extremely easy to teach, and we could come up with the ideal time to achieve the desired viscosity. From then on, paint coverage was more consistent from operator to operator.

The team had just solved two major problems and was excited to do more, but these changes took most of the week. We decided to focus the rest of our time on training the other shifts and crews, to ensure they understood and properly utilized the changes.

At the end of the week we showcased our efforts to the plant leadership team. They were impressed with the improvements, enthusiasm, and creativity of the team. These changes led to reduced downtime and scrap for the line. I was invited to the plant many times over the next few years to work with teams using the same approach. I am proud to say that we were able to simplify many other processes and improve performance all over the plant.

Little Things Mean A Lot

A global consumer goods manufacturer was experiencing high levels of downtime, jams, and long changeovers on a critical production line. They invited Process Improvement Partners to their plant to observe and discuss the problem and identify opportunities for improvement. After reviewing performance, we took a walk to the line. The line was running, and after a description of line components, it became apparent there were quick opportunities to improve performance of the line. The techniques we would use were quite basic: leveling, squaring, aligning, and centering of products with the process. It seemed so simple, and the customers were skeptical. We suggested a five-day Kaizen to improve line reliability, scheduled for January 2019.

Leading up to the Kaizen event, we had many discussions with line operators, mechanics, and engineers, and we made several confirming observations on the line. During a discussion with the Plant Manager, it became apparent he didn’t buy-in to the approach. He had used a process called “Center Lining” before, and had mixed results. In addition, it took weeks to accomplish. We assured him centering of the process would be completed on the first day of the Kaizen and then we would optimize all parts of the process around the center in the following days. He was still skeptical, but heard enough and saw our confidence, and gave final approval for the Kaizen to proceed.

In most Kaizen events, we provide a structure and approach to the team charged with solving a problem. We very rarely dictate specific actions to the team. In this case, the entire first day was controlled and team members were asked to follow very specific instructions before implementing their ideas.

After receiving training on the approach, the team walked to the production line. We reviewed safety requirements, shut down the line, and locked it out. The next step was to identify the center of the critical packaging process. This was the part of the line where everything comes together – the product and the package. We told the team everything leading up to the packaging process should be located and optimized to the center of the process. They didn’t think it would be very important, but were willing to learn and find the center of the line.

We located the center of the line at the midpoint of the conveyor frame on the out-feed side of the equipment and wrapped a string around that point. Then, stretching the string through the equipment, we found the center of the conveyors leading up to the equipment. A trained eye can keep the center precise within 1/32”, so we found what we believed to be center along approximately 100 feet of equipment and conveyor and pulled the string taut. Then, we marked the equipment and conveyor every 4 feet along its length to identify center for the process. Once complete, we noticed all product was coming into the equipment off center. The packaging was tracking off-center as well. That was the first time the skeptical team members saw something they weren’t expecting.

Our next step was to check the levelness of all of the conveyors leading up to and through the equipment. Ideally, all conveyors should be no more than 1/32” out of level at every transition (one section of conveyor to the next section) and side to side. Using a torpedo level and some shims, the team documented levelness of every section of conveyor. They found many of the conveyors were out of level by more than ¼” and some were out as much as ½”. The good news was this condition was easily corrected, and by the end of two hours, all conveyors were leveled throughout the process. The team was losing its skepticism as the products ran more consistently once we started the line back up. The first day ended with the team handing the line back over to the production organization.

The next morning, the team came in energized. They heard from the afternoon shift and overnight shift that the line had run smoothly overnight - much better than anyone had expected. We had four more days to improve things before the end of the Kaizen.

The next step was to optimize the location of the product with reference to the center of the process. Now that we had identified the center and leveled the line, this was easy. The challenge was to determine ways to ensure that our new settings would not change as soon as the Kaizen was over. The team was given the freedom to come up with ways to create and sustain the new settings. Using collars, pins, and labels, the team came up with ways to identify the proper locations for all of the different products running on the line. They also identified the product changeover steps (in the order to be followed) and labeled each part of the line with changeover steps that would need to be accomplished in proper sequence. These labels were made with large, bright green stock, so people wouldn’t miss them and forget a changeover step.

One problem the team identified was that the packaging wasn’t wrapping the product in a consistent manner. Upon further investigation, it was determined a top guiding roller was applying unequal pressure to the corrugated wrapper and the wrapper was shifting from side to side. One of the team members came up with a simple solution - tie all parts of the top guiding roller together to guarantee equal pressure across the wrapper. By doing this, the wrapper consistently met the product every time.

Improvements came fast and furious over the final days of the Kaizen, and by the last day, everyone noticed a significant improvement in line performance. The operators on the line thanked the team for correcting years of problems and even offered suggestions to make things better, which the team was able to incorporate into their work.

At the report out, team members remarked they were surprised how extremely small improvements impacted performance. They also realized these techniques could be taken to any other line in the factory. Once skeptics, they become zealots.

PIP Helps Team in York, PA Improve Reliability of Critical Operation

Many consultants train and teach. I like to demonstrate and verify with teams that they truly understand the techniques for improvement that I am sharing with them. Most importantly, I want them to be able to take this work and transfer it to other parts of the factory without my assistance.

During an event in York, PA, I showed a team of maintenance technicians, engineers, and production operators how to level, square, and centerline equipment during a reliability improvement Kaizen. I demonstrated these techniques to show them how critical even the smallest improvements are. We were able to reduce the out-of-level condition on some conveyers from ½” to less than 1/16”. We also optimized the location of the product that was flowing through the conveyers and equipment. Immediately after doing this work, the production line ran smoother than anyone could remember.

When the team reported their results and findings, the audience was so impressed that they committed to doing this work all over the facility, using their new reliability experts.
