It’s not so easy to move manufacturing work back to the US.

I hear it’s a good idea to move manufacturing work back to the US.

Before getting into what it would take to move manufacturing work back to the US, I think it’s important to understand why manufacturing companies moved their work out of the US.  Simply put, companies moved their work out of the US because their accounting systems told them they would make more money if they made their products in countries with lower labor costs. And now that labor costs have increased in these no longer “low-cost countries”, those same accounting systems think there’s more money to be made by bringing manufacturing back to the US.

At a low level of abstraction, manufacturing, as a word, is about making discrete parts like gears, fenders, and tires using machines like gear shapers, stamping machines, and injection molding machines.  The cost of manufacturing the parts is defined by the cost of the raw material, the cost of the machines, the cost of energy to power the machines, the cost of the factory, and the cost of the people to run the machines. And then there’s assembly, which, as a word, is about putting those discrete parts together to make a higher-level product.  Where manufacturing makes the gears, fenders, and tires, assembly puts them together to make a car.  And the cost of assembly is defined by the cost of the factory, the cost of fixtures, and the cost of the people to assemble the parts into the product.  And the cost of the finished product is the sum of the cost of making the parts (manufacturing) and the cost of putting them together (assembly).

It seems pretty straightforward to make more money by moving the manufacturing of discrete parts back to the US.  All that has to happen is to find some empty factory space, buy new machines, land them in the factory, hire the people to run the machines, train them, source the raw material, hire the manufacturing experts to reinvent/automate the manufacturing process to reduce cycle time and reduce labor time and then give them six months to a year to do that deep manufacturing work.  That’s quite a list because there’s little factory space available that’s ready to receive machines, the machines cost money, there are few people available to do manufacturing work, the cost to train them is high (and it takes time and there are no trained trainers).  But the real hurdles are the deep work required to reinvent/automate the process and the lack of manufacturing experts to do that work.  The question you should ask is – Why does the manufacturing process have to be reinvented/automated?

There’s a dirty little secret baked into the accounting systems’ calculations.  The cost accounting says there can be no increased profit without reducing the time to make the parts and reducing the labor needed to make them.  If the work is moved from country A to country B and the costs (cycle time, labor hours, labor rate) remain constant, the profit remains constant.  Simply moving from country A to country B does nothing.  Without the deep manufacturing work, profits don’t increase.  And if your country doesn’t have the people with the right expertise, that deep manufacturing work cannot happen.

And the picture is similar for moving assembly work back to the US.  All that has to happen is to find empty factory space, hire and train people to do the assembly work, reroute the supply chains to the new factory, redesign the product so it can be assembled with an automated assembly line, hire/train the people to redesign the product so it can be assembled in an automated way, design the new automated assembly process, build it, test it, hire/train the automated assembly experts to do that work, hire the people to support and run the automated assembly line, and pay for the multi-million-dollar automated assembly line.  And the problems are similar.  There’s not a lot of world-class factory space, there are few people available to run the automated assembly line, and the cost of the automated assembly line is significant.  But the real problems are the lack of experts to redesign the product for automated assembly and the lack of expertise to design, build, and validate the assembly line.  And here are the questions you should ask – Why do we need to automate the assembly process and why does the product have to be redesigned to do that?

It’s that dirty little secret rearing its ugly head again.  The cost accounting says there can be no increased profit without reducing the labor to assemble the parts.  make them.  If the work is moved from country A to country B and the assembly costs (labor hours, labor rate) remain constant, the profit remains constant.  Simply moving from country A to country B does nothing.  Without deep design work (design for automated assembly) and ultra-deep automated assembly work, profits don’t increase.  And if your country doesn’t have the people with the right expertise, that deep design and automated assembly work cannot happen.

If your company doesn’t have the time, money, and capability to reinvent/automate manufacturing processes, it’s a bad idea to move manufacturing work back to the US.  It simply won’t work.  Instead, find experts who can help you develop/secure the capability to reinvent/automate manufacturing processes to reduce the cost of manufacturing.

If your company doesn’t have the time, money, and capability to design products for automated assembly and to design, build, and validated automated assembly systems, it’s a bad idea to move assembly work back to the US. It, too, simply won’t work.  Instead, partner with experts who know how to do that work so you can reduce the cost of assembly.

The best time to design cost out of our products is now.

With inflation on the rise and sales on the decline, the time to reduce costs is now.

But before you can design out the cost you’ve got to know where it is.  And the best way to do that is to create a Pareto chart that defines product cost for each subassembly, with the highest cost subassemblies on the left and the lowest cost on the right.  Here’s a pro tip – Ignore the subassemblies on the right.

Use your costed Bill of Materials (BOMs) to create the Paretos.  You’ll be told that the BOMs are wrong (and they are), but they are right enough to learn where the cost is.

For each of the highest-cost subassemblies, create a lower-level Pareto chat that sorts the cost of each piece-part from highest to lowest.  The pro tip applies here, too – Ignore the parts on the right.

Because the design community designed in the cost, they are the ones who must design it out.  And to help them prioritize the work, they should be the ones who create the Pareto charts from the BOMs.  They won’t like this idea, but tell them they are the only ones who can secure the company’s future profits and buy them lots of pizza.

And when someone demands you reduce labor costs, don’t fall for it.  Labor cost is about 5% of the product cost, so reducing it by half doesn’t get you much.  Instead, make a Pareto chart of part count by subassembly.  Focus the design effort on reducing the part count of subassemblies on the left.  Pro tip – Ignore the subassemblies on the right.  The labor time to assemble parts that you design out is zero, so when demand returns, you’ll be able to pump out more products without growing the footprint of the factory.  But, more importantly, the cost of the parts you design out is also zero.  Designing out the parts is the best way to reduce product costs.

Pro tip – Set a cost reduction goal of 35%.  And when they complain, increase it to 40%.

In parallel to the design work to reduce part count and costs, design the test fixtures and test protocols you’ll use to make sure the new, lower-cost design outperforms the existing design.  Certainly, with fewer parts, the new one will be more reliable.  Pro tip – As soon as you can, test the existing design using the new protocols because the only way to know if the new one is better is to measure it against the test results of the old one.

And here’s the last pro tip – Start now.

Supply chains don’t have to break.

We’ve heard a lot about long supply chains that have broken down, parts shortages, and long lead times.  Granted, supply chains have been stressed, but we’ve designed out any sort of resiliency.  Our supply chains are inflexible, our products are intolerant to variation and multiple sources for parts, and our organizations have lost the ability to quickly and effectively redesign the product and the parts to address issues when they arise. We’ve pushed too hard on traditional costing and have not placed any value on flexibility.  And we’ve pushed too hard on efficiency and outsourced our design capability so we can no longer design our way out of problems.

Our supply chains are inflexible because that’s how we designed them.  The products cannot handle parts from multiple suppliers because that’s how we designed them.  And the parts cannot be made by multiple suppliers because that’s how we designed them.

Now for the upside.  If we want a robust supply chain, we can design the product and the parts in a way that makes a robust supply chain possible. If we want the flexibility to use multiple suppliers, we can design the product and parts in a way that makes it possible.  And if we want the capability to change the product to adapt to unforeseen changes, we can design our design organizations to make it possible.

There are established tools and methods to help the design community design products in a way that creates flexibility in the supply chain.  And those same tools and methods can also help the design community create products that can be made with parts from multiple suppliers.  And there are teachers who can help rebuild the design community’s muscles so they can change the product in ways to address unforeseen problems with parts and suppliers.

How much did it cost you when your supply chain dried up? How much did it cost you the last time a supplier couldn’t deliver your parts? How much did it cost you when your design community couldn’t redesign the product to keep the assembly line running? Would you believe me if I told you that all those costs are a result of choices you made about how to design your supply chain, your product, your parts, and your engineering community?

And would you believe me if I told you could make all that go away?  Well, even if you don’t believe me, the potential upside of making it go away is so significant you may want to look into it anyway.

Crossword - Product Technology Innovation

Win Hearts and Minds

As an engineering leader you have the biggest profit lever in the company. You lead the engineering teams, and the engineering teams design the products. You can shape their work, you can help them raise their game, and you can help them change their thinking. But if you don’t win their hearts and minds, you have nothing.

Engineers must see your intentions are good, you must say what you do and do what you say, and you must be in it for the long haul. And over time, as they trust, the profit lever grows into effectiveness. But if you don’t earn their trust, you have nothing.

But even with trust, you must be light on the tiller. Engineers don’t like change (we’re risk reducing beings), but change is a must. But go too quickly, and you’ll go too slowly. You must balance praise of success with praise of new thinking and create a standing-on-the-shoulders-of-giants mindset. But this is a challenge because they are the giants – you’re asking them to stand on their own shoulders.

How do you know they’re ready for new thinking? They’re ready when they’re willing to obsolete their best work and to change their work to make it happen. Strangely, they don’t need to believe it’s possible – they only need to believe in you.

Now the tough part: There’s a lot of new thinking out there. Which to choose?

Whatever the new thinking, it must make sense at a visceral level, and it must be simple. (But not simplistic.) Don’t worry if you don’t yet have your new thinking; it will come. As a seed, here are my top three new thinkings:

Define the problem. This one cuts across everything we do, yet most underwhelm it. To get there, ask your engineers to define their problems on one page. (Not five, one.) Ask them to use sketches, cartoons, block diagram, arrows, and simple nouns and verbs.  When they explain the problem on one page, they understand the problem. When they need two, they don’t.

Test to failure. This one’s subtle but powerful. Test to define product limits, and don’t stop until it breaks. No failure, no learning. To get there, resurrect the venerable test-break-fix cycle and do it until you run out of time (product launch.) Break the old product, test-break-fix the new product until it’s better.

Simplify the product. This is where the money is. Product complexity drives organizational complexity – simplify the product and simply everything. To get there, set a goal for 50% part count reduction, train on Design for Assembly (DFA), and ask engineering for part count data at every design review.

I challenge you to challenge yourself: I challenge you to define new thinking; I challenge you to help them with it; I challenge you to win their hearts and minds.

Heroes of the Company

If I was a company, the first thing I’d do is invest in my engineering teams. But not for the reasons we normally associate with engineering. Not for more function and features, not for product robustness, not technology, and not patents. I would invest in engineering for increased profits.

When it comes to their engineering divisions, other companies think minimization – fewest heads, lowest wages, least expensive tools. Not me. I’m all about maximization – smartest, best trained, and the best tools. That’s how I like to maximize profits. To me, investing in my engineering teams gives me the highest return on my investment.

Engineers create the products I sell to my customers. I’ve found when my best engineers sit down and think for a while they come up with magical ideas that translate into super-performing products, products with features that differentiate me from my cousin companies, and products that flat-out don’t break. My sales teams love to sell them (Sure, I pay a lot in bonuses, but it’s worth it.), my marketing teams love to market them, and my factory folks build them with a smile.

Over my life I’ve developed some simple truisms that I live by: When I sell more products, I make more profits; when my products allow a differentiated marketing message, I sell more and make more profits; and when my product jumps together, my quality is better, and, you guessed it, I make more profits. All these are good reasons to invest in engineering, but it’s not my reason. All this increased sales stuff is good, but it’s not great. It’s not my real reason to invest in engineering. It’s not my secret.

When I was younger I vowed to take my secret to the grave, but now that I’ve matured (and filled up several banks with money), I think it’s okay to share it. So, here goes.

My real reason to invest in engineering is material cost reduction. Yes, material cost reduction. My materials budget is one of my largest line items and I help my engineers reduce it with reckless abandon (and the right tools, time, training, and teacher.) I’ve asked my lean folks to reduce material cost, but they’ve not been able to dent it. Sure, they’ve done a super job with inventory reduction (I get a one-time carrying cost reduction.), but no material cost reduction from my lean projects. I’ve also asked my six sigma organization to reduce material costs, but they, too, have not made a dent. They’ve improved my product quality, but that doesn’t translate into piles of money like material cost reduction.

Now, I know what you’re thinking: Why, Mrs. Company, are you wasting engineering’s time with cost? Cost is manufacturing’s responsibility – they should reduce it, not engineering. Plain and simple – that’s not what I believe, and neither do my engineers. They know they create cost to enable function, good material cost – worth every penny. But they also know all other cost is bad. And since they know they design in cost, they know they’re the ones that must design it out. And they’re good at it. With the right tools, time, and training, they typically reduce material costs by 50%. Do the math –material cost for your highest volume product times 50% – year-on-year. Piles of money.

I’ve learned over the years increasing sales is difficult and takes a lot of work. I’ve also learned I can make lots of money reducing material costs without increasing sales. In fact, even during the recent downturn, through my material cost reductions I made more money than ever. I have my design engineers to thank for that.

Company-to-company, I know things have been tough for us over the last years, and money is still tight. But if you have a little extra stashed away, I urge you to invest in your engineering organization. It makes for great profits.

Radically Simplify Your Value Stream – Change Your Design

The next level of factory simplification won’t come from your factory.  It will come from outside your factory.  The next level of simplification will come from upstream savings – your suppliers’ factories – and downstream savings – your distribution system.  And this next level of simplification will create radically shorter value streams (from raw materials to customer.)

To reinvent your value stream, traditional lean techniques – reduction of non-value added (NVA) time through process change – aren’t the best way.  The best way is to eliminate value added (VA) time through product redesign – product change.  Reduction of VA time generates a massive NVA savings multiple. (Value streams are mostly NVA with a little VA sprinkled in.) At first this seems like backward thinking (It is bit since lean focuses exclusively on NVA.), but NVA time exists only to enable VA time (VA work).  No VA time, no associated NVA time.

Value streams are all about parts (making them, counting them, measuring them, boxing them, moving them, and un-boxing them) and products (making, boxing, moving.)  The making – touch time, spindle time – is VA time and everything else is VA time.  Design out the parts themselves (VA time) and NVA time is designed out.  Massive multiple achieved.

But the design community is the only group that can design out the parts. How to get them involved? Not all parts are created equal. How to choose the ones that matter? Value streams cut across departments and companies. How to get everyone pulling together?

A Recipe for Unreasonable Profits

There’s an unnatural attraction to lean – a methodology to change the value stream to reduce waste.  And it’s the same with Design for Manufacturing (DFM) – a methodology to design out cost of your piece-parts. The real rain maker is Design for Assembly (DFA) which eliminates parts altogether (50% reductions are commonplace.) DFA is far more powerful.

The cost for a designed out part is zero.  Floor space for a designed out part is zero. Transportation cost for a designed out part is zero. (Can you say Green?) From a lean perspective, for a designed out part there is zero waste.  For a designed out part the seven wastes do not apply.

Here’s a recipe for unreasonable profits:

Design out half the parts with DFA.  For the ones that remain, choose the three highest cost parts and design out the cost.  Then, and only then, do lean on the manufacturing processes.

A Recipe for Unreasonable Profits.

 

What is Design for Manufacturing and Assembly?

Design for Manufacturing (DFM) is all about reducing the cost of piece-parts. Design for Assembly is all about reducing the cost of putting things together (assembly).  What’s often forgotten is that function comes first.  Change the design to reduce part cost, but make sure the product functions well.  Change the parts (eliminate them) to reduce assembly cost, but make sure the product functions well.

Paradoxically, DFM and DFA are all about function.

Here’s a link to a short video that explains DFM and DFA: link to video. (and embedded below)

 

Secret Sauce that Doubles Profits

Last month a group of engineers met secretly to reinvent the US economy one company at a time.  Here are some of the players, maybe you’ve heard of them:

Alcoa, BAE, Boeing, Bose, Covidien, EMC, GE Medical, GE Transportation, Grundfos, ITT, Medrad, Medtronic, Microsoft, Motorola, Pratt & Whitney, Raytheon, Samsung, Schneider Electric, Siemens, United Technologies, Westinghouse, Whirlpool.

Presenter after presenter the themes were the same: double profits, faster time to market, and better products – the triple crown of product development. Magic in a bottle, and still the best kept secret of the product development community. (No sense sharing the secret sauce when you can have it all for yourself.)

Microsoft used the secret sauce to increase profits of their hardware business by $75 million; Boeing recently elevated the secret methodology to the level of lean. Yet it’s still a secret.

What is this sauce that doubles profits without increasing sales?  (That’s right, doubles.) What is this magic that decreases time to market? That reduces engineering documentation? That reduces design work itself? What is this growth strategy?

When trying to spread it on your company there are some obstacles, but the benefits should be enough to carry the day.  First off, the secret sauce isn’t new, but double the profits should be enough to take a first bite.  Second, its name doesn’t roll off the tongue (there’s no sizzle), but decreased time to market should justify a taste test. Last, design engineering must change its behavior (we don’t like to do that), but improved product functionality should be enough to convince engineering to swallow.

There are also two mapping problems: First, the sauce has been mapped to the wrong organization – instead of engineering it’s mapped to manufacturing, a group that, by definition, cannot do the work. (Only engineering can change the design.) Second, the sauce is mapped to the wrong word – instead of profit it’s mapped to cost.  Engineering is praised for increased profits (higher function generates higher profits) and manufacturing is responsible for cost – those are the rules.

With double profits, reduced time to market, and improved product function, the name shouldn’t matter. But if you must know, its name is Design for Manufacturing and Assembly (DFMA), though I prefer to call it the secret sauce that doubles profits, reduces time to market, and improves product function.

I can name that tune in three notes.

More with more doesn’t cut it anymore, just not good enough.

The behavior we’re looking for can be nicely described by the old TV game show Name That Tune, where two contestants competed to guess the name of a song with the fewest notes. They were read a clue that described a song, and ratcheted down the notes needed to guess it. Here’s the nugget: they challenged themselves to do more with less, they were excited to do more with less, they were rewarded when they did more with less. The smartest, most knowledgeable contestants needed fewer notes. Let me say that again – the best contestants used the fewest notes.

In product design, the number of notes is analogous to part count, but the similarities end there. Those that use the fewest are not considered our best or our most knowledgeable, they’re not rewarded for their work, and our organizations don’t create excitement or a sense of challenge around using the fewest.

For other work, the number of notes is analogous to complexity. Acknowledge those that use the fewest, because their impact ripples through your company, and makes all your work easier.
