As a reminder, my name is Al Haggerty. And we're going to try to get you oriented here in what we call this, The Start of Your Lean Journey. There we go. So by the time we get done, you're going to be able to differentiate between Lean and Six Sigma. And I know that one of the attendees today mentioned that that's why they came. We're going to talk about the 5S tool. That's a derivative of the original Japanese Lean concepts. And we're going to able to define the difference between Lean and a lean enterprise and stakeholders and recognize why lean six sigma principles are being implemented in aerospace, because it's turned out to be a very, very, very valuable tool. And the fact that today is day one of a journey, It's not something that you just do once and finish. And I was reviewing some of the latest changes, and my wife said, gee, you've done this a lot of times. What are you doing? I said, we're on version six. And she said, what? You changed it six times? And I said, this is continuous improvement. So we're going to talk about that. This is a excerpt from The Machine That Changed the World. And some time, if you get a chance, get that book. And Womack and Jones, an ex-MIT professor, he's still alive, and he's still kicking, and very, very interesting guy-- developed a whole bunch of data. But it started with the automobile industry. The book The Machine That Changed the World is about the automobile industry. And in the late 1800s, cars were brand new, and they were assembled by hand. And then Henry Ford revolutionized the production of cars. And the big thing that he came up with was interchangeable parts. Because before that, we handmade parts. And he came up with the concept, that if we could make all the parts the same, we could put them in an assembly line. And that started the mass production. Well, along came Toyota, after World War II. And Toyota made this huge improvement in how we build cars. Part of it was the concept of statistical process control, in terms of how they literally made the parts. But they invented the whole concept of lean. And as you may know, last year, 2007, which just finished, the Toyota production now exceeded General Motors production for the first time. And from market capitalization, numbers of shares times the value of the stock, they're the largest automobile manufacturers. And as you know, we've gone through a lot of problems with Chrysler, was part of the Daimler-Benz until just recently, when Cerberus just bought them back. But our automobile industry is in trouble. I just read the other day that General Motors lost $36 billion last year. Part of that was buying back the rights of the displaced workers, the severance pay and that kind of stuff, and their health care, and so forth. But you can see the difference between, if you look at this, the auto production in the US, these guys, and with the ups and downs. And every time you do one of these, we get these giant layoffs. The nice, smooth Japanese production is as a function of Lean. They continue to improve, and they have a stable workforce. Their products continue to be better and better. I do a lot of jogging, and if you jog along the road and all that, you take a look at the old cars. The old cars that come down the road-- there are Hondas and Toyotas and the Japanese-owned automobiles. The old Chevys and the old Fords, I mean, you see some of them. But they don't last as long. And a good reason is-- the fact is that these cars, I mean, I tell industry groups. I mean, you ask any college kid about driving a car after 200,000 miles, and they'll say, yeah, I got a Corolla, or I got a Camry. I've got a Honda. And there's a reason for it. Because the fact is that they have all the bells and whistles. And all the bells and whistles keep working. So we just talked about that. In the post-world War II period, General MacArthur wanted to rebuild the industry as part of his-- he was the Supreme Allied Commander in Japan, and he tried to get the industry going. And he brought Deming from MIT, basically, to help get the [INAUDIBLE] a bunch of experts. And he instituted a lot of the statistical process control. And the Japanese took it for granted-- not for granted. They said they did it with a passion. Whereas, in the US, we didn't. And therefore, their cars and their products have worked significantly better. So if you take a look at the early craft concept that was used in the Industrial Revolution in past, just think of a jeweler, a watchmaker. Each one of those little parts was made by hand and filed by hand, put together. And if you wanted to become a jeweler, you became an apprentice. And then you became a journeyman. And then you became a master craftsman. And that was how, in fact, you made the kinds of parts. And if, in fact, you could think of a better way of doing it, the master craftsmen would do it. But it was not spread anywhere. I mean, maybe he would teach his apprentice, or so forth. But mass production, which we just talked about, Henry Ford, that kind of concept, if we were going to build years ago, if I was going to build 12 Apaches, we'd put 14 parts in the line, 14 sets of everything. Why 14, if we're going to build 12? Because we're going to scrap them. We don't do that anymore. But that was typical what we would do. And that's pure waste. And the concept was mass production, reduce the cost, get the efficiency up. And there's no question that this was a lot more productive than the master build it one at a time kind of a thing, of a craft person. But here's a big difference. Inspection was a second stage. We would build it and inspect it, build the part and inspect it. Today, in Lean thinking, we build the quality process into the production of the part. And we're going to show you later on that inspection does not catch all the errors, does not catch all the errors. In fact, I guess the poker chips that we just saw before was a good demonstration of that. And another significant improvement is that the master, the master carpenter, the master furniture builder, the master bricklayer, any innovation was driven by the guy that was doing the work. Here, we had industrial engineers and manufacturing engineers, expert periodic improvements to the process. Under the Lean concept, we want every worker to contribute, every worker to contribute in terms of being able-- there's no question, that the real experts in the job, are the people that do it every day. And trying to glean that information is part of the value of Lean thinking. And the biggest thing is really the focus on the customer. See here the craft-- the jeweler was focused on the task of building that watch. The mass production focused on automobiles. Well, we still want to build automobiles. But the focus was on the product. Here, on the Lean thinking, we're trying to deliver value to the customer. And we'll talk more about that later on-- but trying to deliver value. Want to deliver a Mach 1.6, supercruise high payload, vertical-- or short-- takeoff and vertical landing aircraft, called an F-35, to the war fighter. That's the value. And we want to be able to do it for $35 million apiece. That is the value to the Air Force, which is the macro customer. The pilot and the mechanic are the detail customers of how we think-- so big, big difference in the way we approach the concept. Now, we talked about Six Sigma. Six Sigma was developed by Motorola in the '80s. Now, not too many people wear pagers anymore. But when I was a young engineer, I remember that it was sort of like a status symbol to have a pager. I never got one of the darn things. But pagers were a big deal. And Motorola pioneered that business. And they had 80% market share. Until, once again, the Japanese and the Koreans came along, and they added a whole bunch of features to those things, where they could tell you-- when the buzzer went off, they could tell you who it was and where they were coming from and what time it was, and a whole bunch of features. And they delivered it to the United States cheaper. And all of a sudden, Motorola's business went in the tank. And they tried to analyze what was going on. And they decided that-- they did a Pareto analysis. And we'll teach you about Pareto charts here. But they basically made a ranking of what the issues were. And one of the biggest issues was the fact is that they had to scrap and rework a bunch of these pagers. And their quality was not as good as the Japanese, and they didn't last as long. The pagers didn't last as long, for quality reasons. And so they said, how can we fix this? And basically started to apply the Deming statistical process control to the various design processes, manufacturing processes, and so forth, to improve their quality. And they regained their market share. They regained their market share on the pager. So anyway, Motorola, in the '80s-- in fact, I live in Scottsdale, Arizona, now. And the Motorola facility was the one there that did that. But it was improving quality by eliminating defects. And the concept is reduce variation. We're going to talk a lot about that. But under Lean, we're trying to remove waste. And waste is not the fact that people come to work every day to waste things. It turns out that waste is-- the fact is, if this is the perfect way of doing it, and we're doing it now, the difference between what we're doing now and how good it could be is a definition of waste. The Six Sigma is focused on those issues, a variation that, in fact, causing a problem, we focus on the flow. And you're going to hear the term pull, versus push, and so forth, as we go through this. And we're trying to get rid of the waste to improve the business performance. And it's a lot of small improvements, many of them coming from the workers who do the job every day. And I had to work in a-- Boeing sent me to Japan. And I worked in a Japanese factory for a week and after two days of training, had to improve the productivity of a Japanese worker, who was making large industrial air conditioners. And that guy was 55 years old. And he was moving so fast. And my job was to improve his productivity by 30%. And I thought to myself, there is no worker in the United States that's working as hard and as fast as this guy. And he was doing all these jobs. And I had to figure out that literally, it was a repetitive job and try to improve. But it was a combination. I did it, but it was a combination of a whole bunch of small things. And that's what we're trying to do. So we're going to learn a lot about variation and the fact that variation causes problem and the fact-- we're going to talk about flow and how to get the waste out of the process. AUDIENCE: Question. ALLEN HAGGERTY: Yes, sir? AUDIENCE: A simple [INAUDIBLE]. Where does the name Six Sigma come from? ALLEN HAGGERTY: Statistics. AUDIENCE: OK. ALLEN HAGGERTY: Yeah. There's a chart we're going to show you later on, the day after tomorrow, that will actually explain that. But basically, in statistics, sigma, in terms of variation-- so one sigma is 30% of the part, two sigma is 66%, three sigma, so forth. Six Sigma is 99.99999% perfect kind of stuff. AUDIENCE: [INAUDIBLE] standard deviation. ALLEN HAGGERTY: Standard deviation in statistics. I just came from Boeing helicopters. I was on there for a week last week, helping them on the [? root end ?] fatigue problem on the Apache Attack helicopter advanced composite rotor blade program. And there's a [? root end ?] problem, and I was there to fix it. But we literally take six specimens. It has nothing to do with Six Sigma, per se, but six specimens, and then run out the fatigue test and determine what the high confidence 99.999% stress level is that we can guarantee the life of the part. And so it's used a lot. We talk about the fact that Lean optimizers flow and eliminates waste. Six Sigma stresses quality for the elimination of variation. And certain companies have put all their focus on Six Sigma. And other companies have adopted Lean. And over the last 10 or 15 years, we've seen a convergence of companies that use both, and the idea being is, that if the basic quality problem is something that we can apply Six Sigma methods, it makes sense. But quite often, in the big picture, the flow is all mixed up. And therefore, we're concentrating on eliminating the waste in the flow. So there's a lot of companies that, in fact, instead of having a Six Sigma-- General Electric, for example-- and instead of a pure Lean, have, in fact, merged those two. And so you can see here, Rockwell Collins calls it Lean Electronics, Textron-- Six Sigma. The Air Force new system is AFSO21. Boeing now calls it Lean +. And that's a change just in the last two years. So all of these things have merged together. So we're going to talk about the fundamental concepts that underscore both of those. We were talking about someone mentioned, early in the icebreaker, and why they were going to come here, they wanted to learn the terms. There's a bunch of terms that we're going to expose you to over the next three days. And these terms are the language of Lean. And we'll go through those. And believe it or not, when you take your value test at the end, you'll be a lot more knowledgeable and to be able to explain really what those are. So that's good. And I won't go through those at this point. So we talked about the 5S. There are literally five terms in Japanese that began with the S word. And I can't pronounce them. But they have been translated into English to mean Sort, Straighten, Scrub, Standardize, and Sustain. And I'm not sure you can see this, but this is a typical factory sorting area, receiving inspection, where the parts come in, and they get sorted and inspected. And this is before. And if you can see that right now, there's a place for everything, and everything's in its place. And that has a huge impact on the ability to get the job done efficiently. Let me just relate that to your father's tool box, your father's toolbox on his workbench, or the plumber that you see, or the mechanic on your car. And they're in a toolbox. I know that ratchet wrench is in here somewhere. What our job is to do, as the converse of that in terms of sorting and straightening, is to be able to say, I want our mechanic on the line to have all the tools so that he can be like a surgeon. He can be a surgeon-- scalpel, right. And it's all right there, and he knows exactly where it is. And we want to give him the parts and the paper and the tools-- OK, the parts that I need right here, the tools that I need to do the job, and instructions, so that he knows what to do next, if it's, in fact, he's building multiple products. So we want to be more efficient. And we'll find out that actually, straightening out and sorting out is a big improvement. So we're going to do an exercise. Everybody go into your notebook, into your R notebook. And there's a piece of paper that says, 5-S Exercise, 5-S exercise. It looks like this. Now, what we're going to do is we're going to do a 5S exercise. And we're going to measure our improvement. We're going to put metrics on this. And we're going to, in fact, put you in shifts of 30 seconds. And what a good job to do-- when I tell you to turn the page, I'll time you. You've got 30 seconds. And what we want you to do-- you'll see a bunch of numbers. Don't look, a bunch your numbers. And what we want you to do is to find the number one, cross it out, then find number two, cross it out, number three, up to 49. You have to do it in order-- 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Find the number. Cross it out. Find the number. Cross it out. And then stop when I tell you to stop. Ready? Set? Go. OK. AUDIENCE: 8. AUDIENCE: 4. AUDIENCE: 9. ALLEN HAGGERTY: 9. AUDIENCE: I didn't get any. ALLEN HAGGERTY: OK. [LAUGHTER] AUDIENCE: 3. ALLEN HAGGERTY: So round one, the highest was 11. The average-- the average might have been 5 or 6, something like that. So I'm just going to say, OK, that's cool. OK, so now what we're doing is that we're talking about 5S's. The second S is we're going to sort these. We're going to sort these. And what we've done is that we've removed some waste out of the system, and we've removed the numbers between 50 and 90. And for our product, we don't need those. So what you're going to do is the same thing. We're going to go in order. Find the 1, Cross it out. Find the 2. Cross it out. Find the 3. OK? And on your mark, get set, go. Stop. OK. [CHUCKLING] It's a killer, right? How many? AUDIENCE: 10. AUDIENCE: 10 AUDIENCE: 11. AUDIENCE: 13. ALLEN HAGGERTY: 13. AUDIENCE: 19. ALLEN HAGGERTY: 19. AUDIENCE: 32 ALLEN HAGGERTY: 32? AUDIENCE: [INAUDIBLE]. ALLEN HAGGERTY: 22. AUDIENCE: 15 ALLEN HAGGERTY: Highest number was 22. And the average is about 11, roughly, around 2. OK. We've had a productivity enhancement. We've gone from 11 up to 22. Now we're going to do what we call set in order, or straighten. And just think about a factory. We install the rack system to help locate the numbers. And the numbers go from the bottom to the top and from left to right. OK, that sort of makes sense, right? Bottom to the top, left to right. And that'll help you. So start over on the left, and then go up, and then go to the right side. And we'll talk about it. OK. Stand by. On your mark, get set, go. Good. OK, so round three, 39 was our top. Now, the average is certainly, like, approximately 30. Good. OK. Now you see that straightening paid off. The third S is what we call scrubbing. It's tough to scrub a piece of paper. I mean, so but basically, cleaning the factory, if you think of an electronics factory, if you had a dirty electronics factory, and somebody put a chip down, you'd ruin the chip. I mean, that's a simple example. But there's lots of processes. We make composite-- I just said I was in a [? root end ?] factory, making rotor blades. Composites have to be absolutely clean. So having a factory that is clean helps product. But I can't do something on that one, so we're just going to skip that next one. OK, the next one is what we call standardize. And we've created a system of ordering the numbers from the lowest to the highest, from the left to the right, and top to bottom. We've put one number in each box, OK, make it easy to get our tools. And we know where our plans are. So we now know where the screwdriver is. We now know where the wrench is, and that kind of stuff. OK. Stand by. Ready, set, go. OK. AUDIENCE: 49. ALLEN HAGGERTY: [INAUDIBLE] whoa. [LAUGHTER] AUDIENCE: 49. AUDIENCE: 49. AUDIENCE: 49. ALLEN HAGGERTY: You can see, on round four, we basically did it. We significantly improved the average. Why don't you review that. AUDIENCE: [INAUDIBLE] roughly, looking at the range and the eyeball, mean, we started out real low, kind of consistent, consistently bad, right? As we went through sort of intermediate steps, notice the variation actually got bigger. Some people took to the improvements quickly. Other people didn't. There was actually more variation. In fact, at this last step, we had a weird bimodal distribution. I have a lot of 30s and a lot of teens, right? Some people got that system, some didn't. But the really good system, with some odd exceptions, brought both that our performance went up and very important, got our variation down. There was actually just a couple of outliers here. Almost everybody was on track. ALLEN HAGGERTY: Now, basically, let me translate that to an aircraft example. Years ago-- I mean, I started in this business in 1962-- they would give a worker a job ticket, a job ticket, and said-- the supervisor would get together at 7 o'clock in the morning and say, OK, you're going to build the horizontal stabilizer today. You've done that before. We know how to do it. Here's the job ticket. Clock in on the job. You'd go clock in on the job. And it would tell you that, in fact, you had to go to the blueprint crib. And you'd pull out the blueprints for that, and you'd spread them out. And then it would tell you that you had a part kit. And you'd go to the parts control, and you'd get that kit. And then it says, whoop, I need this tool. And you'd go to the tool crib and get the tools. And now, we start at 7 o'clock. It's about 7:30, and you've been trying to get your stuff together. Today, we don't do it that way. Today, you get your parts and your instructions. In fact, F-18, Apache, and those kind of things, are paperless, paperless. So you have a computer that right now and tells you a illustrated way of getting the job done. And it's right in front of you. And the parts are right there. The tools are delivered with the job, or they're at your workplace all the time. And you can see, you can see, from 5 to 6 to 49, how this is important in terms of being able to sort, straighten, and standardize. OK? So now you know what 5S is. Now, the fifth S is sustain. And what that really means is that clean factory we saw, the fact is, that at the end of the day, you want to be able to put the tools back in the rack where you found them, so that you know exactly tomorrow morning, when we start, exactly where they are. We want to continue to have a clean factory, so that if we drop a chip, or something like that, we're not running anything. So it's tough. This is like clean your bedroom. Yes, Mother. Right? I've cleaned it. I want it clean next week, too. Right? Keep it clean. And as they say here, it's hard to achieve. I used to do a walk-through and created the Golden Broom Award, the golden broom. And we literally had a hardware store broom that we sprayed with gold paint. And we'd walk the factory to make sure that the folks that had the cleanest shop, the sheet metal shop, the machine shop, we want them to keep it clean. Aerospace is the largest exporter in the United States. When we talk about the balance of payments, the aerospace industry always leads in terms of number of exports. It's a [? flagshop ?] industry. Obviously, today, everything is air-shipped. You've got FedEx and UPS. And UPS, there's a very large fleet. It's not just brown trucks. They've got a large number of cargo travels. But we get products-- it used to be only high-value products. Now we get a lot of things. Sushi is flown in daily; fresh iced tuna flown in from Taiwan every day. It's hard to believe-- flies right into San Francisco. So we move people and goods with our global positioning system, and so forth, and our satellites. We've got wonderful information now that we never had from our satellites. Obviously, national security and the concept of, hopefully, going back to the moon and Mars, and the innovation that that technology provides, made aerospace an exciting place to work. But some terrific work that was done here at MIT in terms of studying the evolution of products and innovation-- this is in green color-- I guess that's sort of green-- the number of major typewriter companies in the world. And you can see it goes up and down like that. And at the peak, at the peak, there were 75 companies making typewriters. Now, my mother was a secretary. And her favorite typewriter was a Smith Corona. Well, Smith was a typewriter company, and Corona was a typewriter company. And they merged, and they made good typewriters. Ultimately, Remington made typewriters. And then IBM made typewriters. And when I was a young engineer-- and some of you may have seen these, but you can't even find them anymore-- the typewriter that had a ball on them, the IBM Selectric. And instead of having keys that went like this, the little ball would just flip to the right position and type. And the really good typist could type much faster on those things. And it was a status symbol for the secretaries, if you get an IBM Selectric typewriter. But what happened is that the advent of the computer later on-- I mean, you can't even find typewriters today. I mean, they're in museums. What the research has indicated is that, when a invention happened, a whole bunch of people jump into the industry. And then as the product stabilizes, where innovation, they've gotten about all the gadgets into it that make it better, the process, not the product innovation, but the process innovation-- who can make the typewriter more efficiently, and deliver it to the customer at lower cost, and there's some consolidation-- Smith and Corona get together and become one company. And they, in fact, the numbers of companies reduce. Automobile industry-- I mean, I can-- and Earl and I, we can remember Hudson automobiles, when we were kids, Hudson automobiles and Studebaker and Nash. You folks probably have never-- you might have heard of them. But the Studebaker company started in the world in making Conestoga wagons to go out West. And then they wind up making early automobiles. And in the late '40s, after World War II, they had a very unique company. The automobile industry has gone down from cars, enclosed steel body cars-- look at all this. There were a whole bunch of companies in that industry. And now we have three in the United States. And then, a couple of years ago, Chrysler was not really a US company. It was Daimler-Benz. So the same product phenomenon happened in automobiles. And here we are here. There's a chart that I sent [? Analisa ?] the other day. We had 54 aerospace companies in 1940. And that has consolidated down to where you've got, in the commercial airplanes, you've got Boeing and Airbus. Then you've got some big Embraer and Cessna and some of the folks that make business jets. But the number of companies is really dramatically reduced. And the same phenomenon would have been predicted down here, except during the Cold War, it was important to keep companies alive and keeping what we call a warm base or a hot base, in order to be able to produce them. But the question is, as happened here and here, as the efficiency improved, only those companies that had a better business model really stayed in the business. And so the question is, are we in trouble in aerospace? We hope not. But the point is, the very fact that we're doing Lean, Lean Six Sigma, and transforming ourselves into very, very efficient companies, hopefully that will, in fact, sustain the industry. So that's something to keep in mind. Because we used to say, in Pentagon budgeting, that only the healthy tigers survive. The weak ones get eliminated. And so the name of the game is to keep going. So the question is, the industry that came of age in a court order cannot survive with an obsolete business strategy. And so we're going to talk about that strategy. Now, for many, many years, starting with World War II, the name of the game was high priority, develop the aircraft. This is even pre-missiles. And the way we got the price was, what was the cost? The government would audit the cost, and then you'd put 10% or 15% profit on top of that. And that determined what the price was. Over the last 10 or 15 years, the customer has gotten a lot smarter. And it said, you know, look, this is what we're willing to pay, and this is what we think is reasonable profit-- same as this, 10% or 15%. And if we're going to buy it from you, you better get your cost down. Otherwise, A, you don't get the business, or B, you don't make any money. So the customer determines the price. And we in industry have to lower the cost to achieve the profit. So when we go through a design process, our design has to come up with the fact is that we've got to meet the range-- you guys are aero engineers-- range and payload and reliability and maintainability, and so forth, all of those specs. But one of the key specifications-- we're going to talk more about this when we talk about cost-- one of the key specifications now is achieving the cost. So we talk about design to cost, design to cost. And we keep iterating the design until we achieve that cost. And those companies that don't iterate the design to achieve the cost at the beginning wind up not making money, not making money-- so big issue. So we use Lean to help us achieve and to make sure that we're efficient in all of our processes. So here's some basic data. Now, this is the return on invested capital. And here, this is the average of the capital goods companies. These are the big companies in the United States that manufacture. These are not service industries. These are big capital-- make big equipment. And you can see that basically, almost 8% margin, net margin. And you can see over here, that the return on the invested capital is 11% or 12%. And you hear some of the aerospace companies-- In fact, it's interesting, as we've taught this course, how many of these companies were down here. Boeing and Lockheed, and so forth-- we were all down here about five years ago. And we've, in fact, become more efficient. OK, this is 2007. So actually, it's funny to watch those things. We're becoming more and more-- and Rockwell used to be down here, and they've gone way up here. And actually, Clay Jones is the CEO. I met him back in 2002. And he came to see McDonnell Douglas, because we were doing Lean. And he wanted to learn how to do it. And he went back. And now they have Lean Electronics. And they've done very, very well, done very well. So the point of the story is that the aerospace industry has been moving up into what we call the green zone. So we have red, yellow, green and a lot of the military charts and a lot of industry charts now as a way of communicating-- red, yellow, green, just like a stoplight chart-- not so hot, caution, great. And the aerospace industry, as it's become Lean, is moving in that direction. And it's a gratifying phenomenon. We typically have underperformed capital goods manufacturers. But Lean is driving us to the right-hand corner, which is great. We're talking about enterprises. And that's a key word in Lean. And there's lots of different kinds of enterprises-- Programs-- Joint Strike Fighter or the Boeing 787 Dreamliner, the Global Positioning System. Then you have a multi-program enterprise, for example, Raytheon. I have Raytheon marine electronics on my big sailboat. And we'll show you that later on. The United Technologies is Sikorsky, Pratt & Whitney, Carrier air conditioning, the Otis elevator company-- lots of products, lots of programs. And then we've got the national and international enterprises, the aerospace enterprise, our whole aerospace industry, military and commercial; the European Airbus and the other companies, the EADS. So we can have enterprises that overlap each other, intersect. And we'll show you how they can, in fact, be connected. So what is an enterprise? And it says, one or more organizations will have related activities, a unified operation, and a common business purpose. So here we are here with the end user. And Lean, we focus on the end user. And remember, just a new concept-- is the end user the airline that buys a 787? Or is it the pilot and the maintenance mechanic, because those are the real end users, and we want to make it easier for the pilots and easier for the maintainers? And then engineering's job is to conceive a product design that achieves the value that we want to deliver to the end user. And then manufacturing operations and our supplier network add the value to create the product. And there's a bunch of supporting organizations-- finance, that keeps the books; the human resources people, that acquire the personnel and provide the benefits, and so forth, and do the training; legal, obviously; and then product support. In a military environment, one-third, roughly, one-third of the total life cycle cost is the acquisition. How much do we pay for the development and the production? But 2/3 are the operations and support costs. And it turns out, that if you put the product out in the field, and we've got a good customer here, the maintenance cost, the training cost-- think about training pilots. 50 years ago, it cost $100,000 to train a pilot. Today it's in the millions. But the amount of money for spare parts and repair and overhaul-- so 2/3 of the lifecycle costs are in the product support area. So all of these are part of an enterprise. And you can see the intersections of-- the product development guys send specs to the suppliers to build the parts. They also send specs down to manufacturing with the blueprints to do it, and so forth. So you can see those intersections there. So if you basically have a headquarters-- this could be the headquarters of what used to be McDonnell Douglas in St. Louis. And then you've got a factory there. And it turns out that we, in fact, have suppliers. And we, in fact, go out to our second and third-tier suppliers. What's a second and third-tier supplier? We buy titanium from outfits like RMI. We're buying titanium from Russia today. They have a huge source of titanium. We get Alcoa-- obviously, aluminum. And so those are first-tier suppliers. But we also then go down below that to our machine shops. That Hicksville machine shop on Long Island makes big machine parts for us. And we have to make sure that that whole supply chain is, in fact, synchronized and working. Boeing is having trouble right now on the 787s, because of the fact that the supply chain was a major new innovation, the way they were going to, in fact, build this airplane. Because they gave design responsibility to major subcontractors, who flowed that down to sublevels. And some of those parts didn't flow up on the same very, very aggressive schedule that they put in place for the 787. So supply chain is a key part of it, and they're all part of the Lean enterprise. So here's a multi-program business unit. You've got the end user. OK, let's say that an airline-- but the end user is like a pilot and a mechanic. And you've got employees on the F/A team. Boeing was the prime. Northrop Grumman made the aft section. On that Joint Strike Fighter, the F-35, Lockheed is prime. Northrop Grumman is making the aft section. British Aerospace is making the Ford cockpit. So those are partners. You've got detail suppliers that make actuators and that make alternators, and that kind of stuff. You've got the unions, the IAM, which is the machinist union in St. Louis, the United Auto Space Workers, in Boeing, Philadelphia. Society and Congress are stakeholders in this thing, because the fact is that Congress is paying for it, and society is depending on these products, A, for transportation, and for defense, and so forth, corporately to shareholders. So all of these are stakeholders, because they've got a piece of the action. If we shut down a plant, if we shut down a plant-- we shut down a plant in Columbus, Ohio, and there's a whole bunch of people that aren't working there anymore. There's a responsibility to the shareholders to get value. But on the other hand, part of the stakeholders, in terms of society, is, for example, the communities that we serve. And so all corporations today-- most of the big corporations-- try to be good community neighbors and in fact, try to do things that don't hurt. But I mean, I was on a consulting contract last February, in Detroit, when Ford said they're going to cut 30,000 people. Whoa, boy, talk about sad people. So here, what we're trying to do is have value for all of the stakeholders. Obviously, the value-- we want the best value delivered to the customer. We've promised performance. We've promised price. We've promised reliability to the end users. Our employees, we're saying to you, make good products. We'll sell a lot. You'll have jobs for your families. The unions-- it's the same situation. The shareholders' return on investment-- you buy a share stock, and you want to get dividends, and you want to see the stock price go up. The partners-- Northrop Grumman and Lockheed are working together. The suppliers-- and this is Eaton, that makes electrical stuff. And it's [INAUDIBLE] that makes actuators and Honeywell that does flight controls. And then society-- we're trying to, in fact, have the benefits of being able to fly and go see your grandkids kind of thing. So what is a Lean enterprise? And a good definition-- and in fact, he just came back in the room. But Professor Murman, Professor Murman pulled together a bunch of professors here from MIT about five or six years ago and wrote this book, The Lean Enterprise Value-- Insights From MIT'S Lean Aerospace Initiative. And it says, "A lean enterprise is an integrated entity that efficiently creates value for the multiple stakeholders by employing lean principles and practices." And you remember, these are all of the elements that it takes to create an enterprise. And what we're trying to do is to create value for all people in the total supply chain and in the enterprise. Let me take it the other way around. We have an army officer here. The Air Force spent 20 years developing the F-22. It was called the Advanced Tactical Fighter. The Air Force wanted that for $35 million apiece. it took 20 years to develop, and you can add inflation on that, and whatever. But the point is, today's F-22 costs $180 million, $180 million. The Air Force wanted to buy 750 of them, 750 of them. And what happened is that Congress said, we can't afford $180 million aircraft and buy 750 them. And what happened is over time, now the Air Force can only buy 183, 183. And they wanted 750. Now, there's a lot of pressure right now to try to keep the line going. And whether that happens or not, I mean, the chances are we'll never get to what the customer wanted. And the issue here was the fact is that the value that the customer wanted, the end customer, was not delivered. Because from a strategic and tactical standpoint, having greater numbers gives you an advantage. The problem is we're not going to be able to get that advantage, because we're buying less. So delivering value is a big deal. My favorite example-- and I'll probably talk about it tomorrow-- is that, if I told you that I have a wonderful Ford Focus outside on the curb, and if you sign right here, it will only cost you $60,000 for the Ford Focus, and you say, Al, I don't think I want that, right? The point is that intuitively, we know what value is. And $60,000 for a Ford Focus doesn't intuitively compute. And so the name of the game is the market people tell us what is it that the customers want. And it could be a Mach 1.6 $35 million Joint Strike Fighter kind of a thing. Or it can be a $220 million large 747. Or it can be a laptop computer for $900. But we all know intuitively what the features and the attributes that we're looking for and what we sort of want to pay. And if, in fact, we can conceive the design and iterate the design and get the waste out of it, so that we can deliver that value to the customer, we'll be able to sell them. And the enterprise will thrive. And all those stakeholders, all the stakeholders have a piece of the action. And we've got happy employees and happy communities and happy shareholders. So we talked about business acquisition, market research, engineering, define the requirements, iterating the product design, and coming up with robust processes to make repeatably, to get the variation out of them at high quality, managing the supply chain down through the second and third tiers and [INAUDIBLE],, efficiently producing these. And then, obviously, we have to deliver them to the customers and then support them for the life cycle. And so those are those big lifecycle processes. But then there's a bunch of supporting infrastructure-- finance, information technology, human resources, and so forth. And Lean applies to these, too. Every one of these processes can be more efficient. I used to do Lean lectures at Boeing, in addition to my job as vice president of engineering. And I had a contracts administration person, who's actually a lawyer. And all of a sudden, he says, Al, I got it. I can see why we want to be able to get on contract sooner. Because we have a whole bunch of people trying to wait for the contract go ahead. And these guys are still fooling around, trying to get the terms and conditions. And so they were trying to get the contracts administration folks even leaner. So that's the book. And I heartily recommend that you get it, Jim Womack and Dan Jones and Dan Bruce. And The Story of Lean Production-- How Japan's Secret Weapon in the Global Auto Wars Will Revolutionize Western Industry-- and it has spread from the automobile industry in Japan to the aerospace industry. And now, hopefully, Detroit's going to get the message. But a three-star general in the Air Force said, "Can the concepts and principles and practice of the Toyota Production System be applied to the military aircraft industry?" And they gave a contract, a sturdy contract to MIT. And in the early '90s, the answer was a resounding yes. And if we focus lean on enterprise valuation and creation-- and Professor Murman for more than 10 years led this whole effort and was very, very successful in developing a body of knowledge, a body of knowledge that really works. All the major aerospace companies are using it. It does produce value. In fact, now we're trying to spread it to the health care industry and other organizations. But Lean does pay off. And in fact, the Air Force said, you've got this great body of knowledge. And we now know that it does work. How do we spread that and diffuse it, so that it's being taught in colleges? And the Lean Academy, of which this is a piece, was created about five years ago to disseminate this whole body of knowledge by conducting courses like you're in right now. So here's some examples. This was General Dynamics and then Lockheed on the Atlas program. You can actually see that on the initial development, it used to take 48 and 1/2 months. And they actually got it down to 36 months and down at 27 months, ultimately got it down to 18 months, going through a series of major changes and going through the Lean processes to, in fact, achieve what they wanted. The F-18, Super Hornet-- huge change in requirements-- more payload, three times greater ordnance bringback when they land on the carriers, 40% increase in unrefueled range, five times more survivable, designed for growth, big change in reduced support costs, and multi-mission. And they did it within budget, did it on schedule-- well, actually, ahead of schedule-- 1,000 pounds underweight. And there's a high correlation between those program management practices and our Lean enterprise. And that's all the way from trying to do all of these various missions, as you can see here. It's one of the big success stories of industry. And Rockwell Electronics-- we mentioned Clay Jones before-- 25% improvement in productivity, 46% reduction in inventory, cycle time reduction-- big deal-- 75%. And it also works in the office, on technical manuals, on paper-processing, accounting, publishing cycle time-- 72% reduction, work-in-process reduction-- 70%, 38% productivity improvement. So it does apply everywhere. And we're going to give you some exercises that talk about it. Kanban is a Japanese word. And it's a Lean tool that we use a lot. We use it in the office in terms of processing engineering drawings, and we use it in out in the factory. And there's several ways of making it apply to the movement of material and parts in the factory or information, information like in drawings and the parts cards, and so forth. And sometimes it's actually done with a card. And we're going to go through some Kanban exercises here. But basically, what it says is that-- you remember, I told you originally, if we were going to build 12 Apaches, that I'd put 14 parts out there. And you'd give all 14 forgings to a machinist and say, here's a job card. Go do it. Now we give him one. And we, in fact, when he finishes machining that, he looks over here. And there's a card that says he can go get his next piece. And then he puts a card in. And we move it. We do single piece flow. Because if he makes a mistake on 12 forgings in machining them, we've got 12 rework parts and 12 scrap parts. So empty part-- one way of doing it is an empty parts bin. So in fact, he sees an empty one. The parts guy fills it up. An open space on the production floor-- we paint yellow boxes on the floor. And so if the part is there, I grab that part. And when it's empty, the production control guy says, oop, give him another part. So that's another way of doing it. It reduces inventory. It reduces scrap and rework. And then we do the same thing with engineering. You can have racks on the wall for them to do that. So it took 30 years for Toyota to develop all aspects of this system. And you can see that they did their early experiments with Kanban in the '50s. it took them 10 years, and they put it company-wide. And then they drove it all the way down to their first, and second, third-tier suppliers. And they're continuing to develop what we call the Toyota Production System. Boeing now, for example, calls that the BPS, the Boeing Production System, which is basically the Toyota Production System. And they're very, very proud of that. So how long do you think it might take a large aerospace company to implement Lean thinking across their enterprise, starting with the knowledge now available? So in your folders, you've got some cards, colored cards. I think they're 3 by 5 cards. They're colored cards. OK. How long do you think it would take? There's a blue card for 20 years, a red card for 10, green for 5, and yellow. How long do you think it would take a large aerospace company to implement Lean across their enterprise? Just hold up the card at-- blue card? OK, you can hold them up. Wow, I see a bunch of red cards, yup, red and blue. You're right. It takes a long time. I mentioned to you, that was in addition to being vice president of engineering, I was the head of Lean for Boeing Integrated Defense Systems. And when you think about the Apache and the C-17 and the F-15 and the F-18 and the Chinook and the Apache-- and I had all of those-- it takes a long time to get all the organizations up to speed and to drive all these principles down. And it's just a lot of work, and it's a continuous journey. So welcome. You've taken step one. And the takeaways on this is that Six Sigma started with the Japanese automobile industry, and then the electronics industries, and now into the aerospace industries. And I mentioned to you now that the hospitals and the health care people are interested. And if you watch, next time you go to the hospital or your mom and dad go to the hospital, and all that, and you see the bill for an operation, or something like that, you know how very, very expensive it is. My daughter-- my sister just had both knees replaced-- $70,000. Can you believe that? And Medicare paid for that, because she was having trouble walking. But I mean, $70,000 is a lifetime of [INAUDIBLE].. But our medical business could stand some Lean thinking. And enterprise has a core and extended boundary-- and the extended boundary-- the employees, and the suppliers, and the communities, and the stockholders. And certainly, today is step one of learning this. And you can continue to bring it back and keep thinking about it in almost anything you do. So just on a card, on one of those white cards, just write down, for example, for your particular department-- I guess we're a little late here. But anyway, write down just quickly who are the stakeholders. If you've had an internship in industry, an internship in industry, just write down-- you don't have to put your name on it-- write down who the stakeholders were for that function. If you were in engineering design, who was the stakeholders? Put it down. OK?
