"There is a goldmine of costs and wastes that can be reduced in every company." Real-World Examples of SuccessTyco Flow Control has a plant in Black Mountain, N.C., that manufactures valves. In a recent project, it used Lean tools to completely evaluate and modify the way it conducts business, Calvin says. The plant was significantly aligned to be more efficient. Productivity was improved and new savings were realized in excess of $1 million annually. The efforts helped produce a more engaged workforce, product enhancements and improved operating efficiencies. The project investment paid for itself in the first four months after completion of the project. Peerless identified a project to improve changeover times in its test labs. "When we test a pump, the changeover time from pump-to-pump can be as long as an hour and 40 minutes (including time to switch out the piping and all the other things that go into moving a big horizontal pump off a test stand)," Patterson explains. "Through our Lean efforts, we have been able to essentially cut our average changeover to about 20 minutes. We had not improved that changeover time in 30-40 years, so we have been essentially wasting all that productive time. "I do not know how to begin to equate what this savings means in terms of overtime and productivity. It is staggering. The real benefit is we will be able to test more pumps and the system with better quality and not have to hurry through the process. Ergonomically and safety-wise, it is so much better. We have gone from tightening hundreds of bolts through colon pipe and flanges down to 20 to 25 bolts. All this was accomplished just by looking at the problem a little differently. We did not have to invest a lot of money. You can make vast improvements without making a huge capital expenditure." Dave Olecki, continuous improvement manager for Peerless, describes another program that benefited from Lean initiatives. "In one area there is a subassembly where we build large batches of one part at a single time," he explains. "From start to finish, it was probably a month's worth of parts. So we would build 40 or 50 of them and just use maybe two of them that day. The rest would sit on a rack for a month. So not only did you have the extra inventory sitting there, but the workers were not too happy because they had to build these 40 parts really quickly and then watch 38 of them sit on the rack." Peerless solved the problem by applying Lean with a one-piece flow. "It only takes five minutes to build one single unit," Olecki says. "So we decided to just build one at a time as we actually need them. We now have a very small buffer of inventory of these, maybe one or two. This simple decision allowed us to reduce inventory by 75 percent. The operators are happier because they only have to build the parts as needed instead of rushing, and possibly working overtime, to make a huge batch and then watch them sit there." Lean for the BeginnerCalvin offers simple tips for companies looking to implement Lean tools. "A lot of what I see in the marketplace-no matter the company's size-is Lean for Lean's sake," he says. "People decide they are going to do Lean and maybe try a few improvements. But the reality is they often did not have a significant customer or business impact. Yes, the project area did get a little better, but if you asked the customers if anything changed, they would not be able to experience it. You often would not be able to see it on the financials. "What I always recommend-no matter how big or small the company-is to understand what gaps you have in the business. If I am a small company, I may have a productivity issue. I may not be able to get enough shipped out the door with my current resources, and I do not necessarily want to hire more people. It may be that the business in a down market, and I have a cash flow problem. Lean can help in all of these areas.
"Know your target. Know your gap. By knowing that gap and clearly understanding it, that is when you discover what needs to be done, and you can identify the tool set that is going to help this situation. The Lean tool does not need to be exotic or complicated. It is very procedural. You just have to target those gaps and really focus on using Lean principles. "At Tyco Flow Control, one thing we do well is measuring accurately the results on all types of projects. We involve our finance people. I can understand the answers to questions like . . . 'Did I change my cost on payroll? Did the cost of capital go down? Do I have less tied up in inventory now because I implemented these Lean principles?' Those principles are-in many cases-common sense. But I do not recommend starting with Lean for Lean's sake-start with an identified function that needs improvement. Then, apply Lean in those areas that will help improve the function. As you have successes, then you can expand the focus to larger implementations. The payback can be pretty quick if you do it right." Culture ChangesLundgren admits that changing the culture of a business through Lean initiatives can sometimes cause tension. "Lean is so powerful, it can be controversial," he says. "Sometimes people fear headcount deductions. Also, it can be a different way of doing things, and it takes a while to learn." However, Calvin contends that Lean and Six Sigma are both about improvements and change. "Change is not the most welcome thing for some people," he says. "Lean-when properly implemented-is going to have benefits and will make the company stronger. It can open new opportunities for both the business and the employees." Patterson says Peerless will not displace a worker because of a Lean improvement. "A lot of things we do will challenge a worker so that he can be more productive," he says. "We are changing the environment so we can get more out of him. At the same time, for all the right reasons you have to solve a lot of other problems-ergonomic issues, safety issues, quality problems-and it all leads to more productivity. "We are firm believers that we are not going to have fewer people working here at Peerless because of Lean initiatives. We will be more responsive to our customers needs so hopefully they see more value in using Peerless." Trial and ErrorImplementing Lean and Six Sigma tools requires patience, Calvin says. Sometimes lessons are learned from elements of a project that did not work as well as expected. "Even with all the plans, calculations and layouts, sometimes you overlook something," Calvin says. "That is part of getting the culture change across that this is not an end result or a final destination. We are going to continuously improve." One of the lessons learned from the Black Mountain project involved a challenge as a result of accelerating the production line. "We machine, assemble, test and ship the product," Calvin explains. "We actually sped things up so fast that as the product went through the high temperature steam test we no longer had time for it to cool down before the next operation. This helped us identify that we now needed to install a cooling device in the line so employees would not have to wait for the part to cool down in order to finish the assembly operations and box the product. That is one of those things . . . it is a mistake, but it is one of those good mistakes because our production was happening so quickly that we now had to figure out how to improve cooling time to sustain improved efficiencies." Patterson agrees that trial and error is simply part of the process. "We cannot be afraid to fail," he says. Lean must be a company-wide effort and requires support from the workers in the main office to the factory floor, Patterson says. "Throughout your Lean journey, the folks on the floor will be the ones who perfect solutions. They are the process owners-the ones who deal with it every day. A lot of what we do goes toward the psychology of improvement of the guys in the office and on the floor to engage them to come up with solutions. It is not just myself and Dave and his three Six Sigma Black Belts who are coming up with solutions. We end up having several hundred people working toward the same goal."
