A simple story sums up the issue. 3M makes a line of a simple picture hooks under the Command brand name. Until recently, the production process in a sense started in an 3M adhesive plant in Missouri, from which the sticky stuff was shipped 550 miles to another 3M plant in Indiana, where the adhesive was applied to polyethylene foam.

From that factory, the work-in-process was shipped 600 more miles to Minneapolis, where a contractor applied the 3M logo and the WIP was sliced into the right sizes. From there, another 200 mile trip to a contractor that added the hooks and did the final packaging. 1300 miles of supply chain travel in total for a product that just sells for a few bucks.

The term "hairballs" for such supply chain complexity was apparently coined earlier by George Buckley, who recently retired after years as 3M's CEO and who launched a program to reduce some of that complexity.

John Woodworth, 3M's senior vice president of supply chain operations, told the Wall Street Journal that "We had long supply chains. It was and continues to be an issue."

Some complexity is inherent in a company that has some 65,000 SKUs across its many divisions, and operates 241 plants in 41 countries. Two-thirds of its sales now come from outside the US.

From our view, the complexity is perhaps at times compounded at 3M because a number of its businesses and plants are suppliers to other areas of the business, as locations and processes needed to support external customers can add complexity, time and distance for internal manufacturing flows.

The point person responsible for leading the war against hairballs is Jim Welsh, a vice president responsible for manufacturing and working with suppliers. He leads a team of 3M supply chain executives that is currently focused on 18 "high-impact" opportunities to improve efficiency in in manufacturing and supply chain.

The general goal is to reduce manufacturing cycle times by 25%.

"3M's long-term plan is to have fewer, larger, more efficient plants, and spread them out around the world," the Wall Street Journal article says. "More production will be done in what 3M calls "super hubs," plants capable of making scores of products for a region of the world. 3M now has 10 hubs, including six in the U.S. and one each in Singapore, Japan, Germany and Poland. It plans at least six more, all outside the U.S."

The hub strategy has already played out in the production of the Command picture hooks. In 2010, consolidated all the steps needed to make the hooks at a plant in Minnesota, where a number of products, such as Scotch tape, Nexcare bandages, furnace filters the hooks and other products are produced.

That plant now creates finished Command products for the Americas while sending giant rolls of unfinished sticky foam to Singapore and Poland, where they are tailored for Asian and European markets. With this strategy, the cycle time for making Command hooks has dropped to 35 days from 100 seen when using the old supply chain flows.

Another example: 3M's Littmann stethoscopes used to be made in steps involving 14 outside contractors and three 3M plants. Now all processes are being brought into a plant in Columbia, Mo. As a result, the cycle time will fall to 50 days from 165, 3M’s Welch says.

It isn’t stated in the article, but to us it seems that the hub strategy appears to mean that more processes will be brought in house, versus use of outsourcers to perform various steps in a multi-phase manufacturing process.

The hairballs (a term, by the way, 3M doesn't much like using today after Buckley’s retirement) not only added operational costs and created long cycle times, they of course also increased 3M’s inventory levels, as buffer inventories were held at multiple locations along the chain. The hub strategy should reduce those inventory levels.

The question of course is how did things get this way before the recent effort to eradicate such complexity. From our view, sometimes such complexity, especially in very large companies, simply grows over time almost of its own nature until some executive leads the charge to reverse course.

Interestingly, 3M itself says that a conservative, risk-adverse culture also played a key role.

Because it was reluctant to make many investments in a product line until it proved itself in the market, 3M would avoid buying new equipment or build new plants. So 3M product engineers "would look around for available machines and expertise even if it was hundreds of miles away. That meant 3M could keep machinery running round the clock more often, gaining efficiency. But it also meant more costs for shipping and longer production cycles."

Welsh says 3M's new strategy is to ramp up production much faster when it has a hit product and avoid "disjointed supply chains" - a nicer sounding term than hairball.

What's your reaction to the 3M story? Do lots of companies have such hairballs? Is outsourcing actually a contributing factor? Let us know your thoughts at the Feedback section below.

Great article. I am a little suprised not to see BNSF in the mix while I understand their financial mode/operation is a little different. 

That would only give a complete perspective with all the players in the pool.

Using the right tool for the right job has always been a best practice and one of the reasons, we feel, that RFID has never taken off in the DC as exponentially as pundits have been forecasting since 2006. While these results may seem surprising to those solely focused on barcode scanning, the adoption of multi-modal technologies in the DC makes perfect sense for greater worker efficiency and productivity.

The IoT Platform in this year's (2016) Hype Cycle is on the ascending side, entering the "Peak of Inflated Expectation" area. How does this compare to the IoT positions of the previous years, which have already peaked in 2015? Isn't this contradicting in itself?

Editor's Note: 

You are right, Internet of Things (IoT) was at the top of the Garter new technology hype curve not long ago. As you noted, however, this time the placement was for “IoT Platforms,” a category of software tools from a good number of vendors to manage connectivity, data communications and more with IoT-enabled devices in the field.

So, this is different fro IoT generally, though a company deploying connected things obviously needs some kind of platform – hoe grown or acquired – to manage those functions.

Why IoT generically is not on the curve this year I wondered myself.

I agree totally with Mr. Schneider.

I have always lived by "put it in writing" all my work life.  I am a firm believer of the many benefits of putting everything in writing and I try to teach it to as many people as I can.

This "putting in writing" can also be used for almost anything else.  Here are some general benefits (only some) of "putting in writing":

1. Everything is better understood between parties involved.  There are lots of people types who need something visual to improve their understanding.
2. Everyone can read to review and correct anything misunderstood.  This will ensure that all parties concerned confirm the details of the agreements as correct.  This is further enhanced by having all parties involved sign off on a hard copy or confirm via reply email.
3. Everything has a proof.  Not to belittle the element of trust among parties involved, it is always safest to have tangible proof of what was agreed on.
4. There will be a document to refer to at any time by any one who needs clarification.
5. The documentation can be useful historical data for any future endeavor.  It provides inputs for better decisions on related situations in the future.
6. This can also be compiled and used to teach future new team members.  "Learn from the past" it is said.

There are many more benefits.  Mr. Schneider is very correct about his call to "put it in writing".

U.S. companies are reshoring and foreign companies are investing in U.S. locations to be in close proximity to the U.S. market for customer responsiveness, flexibility, quality control, and for the positive branding of "Made in USA".

Reshoring including FDI balanced offshoring in 2015 as it did in 2014. In comparison, in 2000-2007 the U.S. lost net about 200,000 manufacturing jobs per year to offshoring. That is huge progress to celebrate!

The Reshoring Initiative Can Help. In order to help companies decide objectively to reshore manufacturing back to the U.S. or offshore, the nonprofit Reshoring Initiative's free Total Cost of Ownership Estimator can help corporations calculate the real P&L impact of reshoring or offshoring. http://www.reshorenow.org/TCO_Estimator.cfm

Lora, great article! I agree that companies choose the 'safe' solution more often than not. My solution is a bolt-on for legacy ERP's and we even face challeneges of customer adoption. Most like to play it safe and choose an ERP upgrade, which is more costly, time consuming, and has lower ROI across the board. Would love to learn more about your company, we are always looking for partnerships.

If we limit the standard on judging or determining the best supply chain to just three calculations it does not tell the entire picture.  Financial performance metrics are valuable as they capture the economic consequences of business decisions.  But supply chain managers make decsions and use organizational resources that impact a company's financial well being.  Where is a firm's earnings over a period of time determined by sales less product costs and general/adminsitrative costs?  Where is the metric for determining the sources and uses of cash from three perspectives - operational, investment and financial?  Where are these supply chain metrics: on-time delivery, lead time, response time to customers, product returns, procurement costs, network distance, inventory carrying costs, forecasting accuracy, sourcing time, etc,.  Without knowing the results of all these supply chain calculations the there must be a question as to the accuracy of the 25 top supply chains.

I feel this ranking misses the mark in SC. It does not seem to consider a key indicator in days inventory on hand, which is key to determining a SC company's ability to forecast, manage inventory costs and reduce aged stock. In additiion I realize it's difficult to understand what goes into the customer survey, but would I assume specific metrics are being asked. For examples customer's opinion on service level differentiation and the ability to deliver the right product on time, which should then be allocated a bigger weighting than 10%. It would also be interesting to take a view of the above list's SKU portfolio complexity, seasonality and launches/promotions. I would again assume some companies on the list above have a far more complex SC to manage and lead, ultimately requiring a lot more innovation within a SC to stay ahead of competitors, and ultimately satisfy their customers demands.  I understand above metrics are difficult to measure, as mentioned in the article, but they somehow need to be considered to give a true reflection.

A Very Good Article...

While some feel that lean is a scam that pushes for more out of the personnel and out of the companies through reduction of waste and adding value for the customer, there are several things to remember:

1) Lean methodologies are designed and implemented to reduce time wasting, so this may seem that you are working harder as an employee.

2) Lean methdoligies only work when everyone from the janitor to the owner of the company get involved and back the program.

3) Lean methods are there to make you work smarter not harder, although it may feel you are working harder.

4) YES... Sometimes lean methodologies fail! This is due to project overun or taking on too large a problem and trying to fix it all in one go and not taking the smaller problems that are associated with the large problem and fixing them first. Sometimes fixing the small problems leads to resolution of the larger problem.

The Supply Chain technology is not considered a problem because traditionally supply chains are thought to be cost centres unlike sales functions. The tendency, in general, to limit expenses and cost cutting on upgrades for technology and for talent have been hindering progress for the businesses. Supply chains lack real time visbility and above all trust across the value chain (not that the participants are dishonest) rather it's about the cascading effects referred to as the bull-whip effect which causes higher magnitudes of disruptions. 

Supply chain real time information should top the list .

Another problem is that of multi homing as so much data is available across several feeds of IOT/Email/Internet /Mobility/ERP that organisations tend to have issues around finding a single platform to collate them for meaning analysis. 

Blockchain (if deployed appropriately) can be a great solution for solving the issues around the supply chain.

Excellent article.  It very much points to the need for Shared Risk / Shared Reward as we teach at Vested.  Suppliers will respond when they are made part of the team, and they have a lot to bring to the game.  The service provider is the subject matter expert in the services provided, and in an excellent position to enhance the capabilities and services offered by the shipper.

As the article points out it is not a lack of technology that is holding back performance but rather a failure to form the right sort of relationships.  As well as the length of such relatiohships, practitioners should consider employing arrangements that incentivise both parties to innovate and deliver levels of performance and profit that neither thought possible.  By far the best model I have come across to achieve this is the Vested Outsourcing model developed by researchers from the University of Tennessee.  See www.vestedway.com for information on the model and case studies that show how others have benefited from creating a Vested deal.

I have recently co-authored a white paper with my colleague wherein we have looked at 2 fundamental guiding principles  -

1. Always have enough to Sell / Produce
2. Do not have excess to Sell / Produce

These 2 Golden Rules can be the foundation of keeping optimal inventory levels and for organizations to achieve the same. We have looked at a framework which tries to reduce the phase mismatch between Demand & Supply, and tries to bring the shape of the supply curve closer to shape of the demand curve.

We have classified symptoms and underlying root causes for the above "Phase mismatch" and "Curve Mismatch" between Demand and Supply, and then talked about addresssing those individual root causes to strive towards Leaner Inventory levels while maintaining or improving service levels.

So to answer your question, we feel the Companies which have addresed these causes have been able to keep DIO horizontal or even going down, while others have not been able to control rising DIO because of not addressing the root causes.

You ask why turns are flat or declining despite lots of attention and technology. The answer is, I think, 2 fold: the supply chain environments VUCA (Volatliity, Uncertainty, Complexity, Ambiguity) is on a continuous upward curve and this means that forecast accuracy inevitably declines in parallel - and much of that inaccuracy is hidden by the statistics. For instance a company with, seemingy good, 80% mix accuracy will find that figure is skewed so high by the few high volume / low variability items. 80% of the items will be achieving considerably less than 60% error.

So most item level forecasts used for driving replenishment through an MPS (be it ERP or APS) are simply leading to unbalanced stocks, service threats and continuous expediting / fire-fighting. These schedule interrutions are "variability" that is disrupting flow and, thereby, increasing lead-times, using unplanned capacity and generating excessive (and still unbalanced) inventories.

The replacement in ex-stock supply chains is "enterprise(s)-wide" pull which also uses "push" for extreme/exceptional events. Its other key characteristics are that the supply chain is decoupled and is demand-driven. And now it can be implemented using SAP since they announced they they have co-developed an enhancement for IBP that supports this transformational way of working - up to 50% inventory reduction, requiring less capacity and shorter lead-times all while achieving planned service levels.

IoT is without a doubt starting to become a major factor in the profitability of various companies. In the manufacturing sector, we will see it come into the front by the end of 2020 completely. Various sectors have already adapted IoT solutions like the security industry or companies offering BPO Services India. Contact centers not just in India and China but across the world have adapted technology following the principles of IoT. The manufacturing sector is soon going to follow.

I  can speak with some context. While efficiency and tools can reduce inventory, we also see the number of SKUs and new products increasing, and also the number of sales/depot points. This means the inventory in such cases, can start with very high number and with more customization and choices available to the consumer, so there is no end to the long tail of products available within a category. It is unlikely that the slow/dead goods are written off so easily to be not included here.

A larger question, would it be purely an IO problem or also a Demand Planning (Forecast Error) problem? A higher cycle time of service but a better fill rate can improve inventory performance, by aggregation. But a bad forecast can do away all the good work you do in inventory planning.

Do you have numbers for decorative coatings in the list? I did not see something there only for decorative coatings.

My opinion is that peaks and valley are just nice graphics to explain.  Smooth responses save the day.   3PLs  just adjust to the climate and the areas of movement of Logistics.    One purpose of the 3PL movement was to adjust to an always changing market.   They will never be fixed and will flex as the logistics changes.   3PL companies have vast knowledge of their business.  Their success is their ability to move up and down as the market flows.  They bring a level playing field to the transportation world that in the past was rigid but looked good on spreadsheets.  Industry graphic personnel like to be able to answer all the changes because they can only see documents.  3PLs see the needs, the issues, the positive changes and the knowledge to know why and when to adjust.   They (3PLs) have smoothed the waves of the past and everybody likes to see the spikes so they know something is there to clearly report on. Smooth sailing is boring but sure gets you where you want to go.

In My Opinion, the fact that capacity will tighten should be obvious to everyone engaged in the transportation. 
Capacity to move freight isn’t how many trucks or trailers are in the system or what a computer 
program says, it still is truck driver based and poorly-managed companies won’t be able to imporove
this fact.  Investing in people is still most important!

Get ready to pay higher prices for goods and services. I think we could lose 10% of Capacity in many areas.

Gone are the days when consumers will wait for a retailer to have the product back in stock, those days are done. We live in the "I want it now" society and with Amazon in their pocket consumers can easily "now" it to themself the next day right from their phone.

The importance of product availability is under the microscope at all retailers as an empty shelf equals lost customers, a poor customer experience and entirely abandoned purchases.

We are on a mission at krunchbox to help suppliers fix their product availability and sell thru and improve their buyer relationships, hopefully before their retail partner fines start rolling in and or we see more retailers close.

You are correct There are government programs to encourage investment at small and mid-size manufacturers, but McKinsey says these programs generally have smaller budgets, less certainty of ongoing funding, and more constraints on their mandates than comparable programs in other countries. Policy makers should examine which existing initiatives are producing the most promising results, then scale up those efforts and commit to them for the long term.

We've heard the term “hairball” used in many contexts, but to the best of our knowledge not in the Supply Chain.

Until now, that is, as industrial giant 3M tells the Wall Street Journal that it has been working hard to remove a series of hairballs from its supply chain network.

The basic problem: overly complex movement of goods and too many product touches across 3M's vast network.
