A Formula For Successful Lean Implementation

While Lean management continues to be one of the most prevalent business improvement approaches in the pharma industry, unfortunately, sustainable success has been elusive.   I have written an article published in the latest issue of  “Pharmaceutical Manufacturing” that is a sequel to the series I began years ago, and continued in the January issue of this year on addressing the challenges to ensuring successful implementation.

This article addresses the root causes identified in the January issue, namely lack of senior management commitment and involvement; an emphasis on driving cost reduction benefits (primarily in labor force reduction) over revenue enhancement and strategic benefits; and the continued siloed focus on application to manufacturing rather than across the enterprise.  I’ve utilized my learnings from leading large-scale lean implementations, conversations with lean experts like Richard Schonberger as well as industry executives, to detail the key elements that address the root causes of these challenges.    Many thanks to Rob Fromuth for sharing his experiences and learnings.

I hope this article is of value, and please let me know if you have any comments/feedback.

Lean Six Sigma  – Where Do You Start?

Lean and Six Sigma are the two of today’s most popular business improvement approaches.  Six Sigma drives improvements in quality and reliability by reducing variation using a problem-solving methodology known as “DMAIC” (Define, Measure, Analyze, Improve, and Control).  Lean is a proven approach to eliminating waste in new product development, manufacturing, and distribution in order to cut lead times and investment, increase flexibility and reduce costs.  Lean involves using as little as possible of the available resources – including time – to deliver value to customers.

When a company-wide Lean and/or Six Sigma program is begun, the first challenge that managers and improvement teams face is knowing exactly where to begin improvement efforts.   Waste elimination is contingent about first being able to identify waste.  You cannot eliminate what you can’t see.  Likewise, it is difficult to pinpoint root causes of variability in an unstable work environment.  In many workplaces, firefighting is common and problem solving is reactive in nature versus proactive.  Trying to implement an improvement program in such an environment is a formidable challenge – where do you start?

This is where an approach called “5S” comes in.  5S is an approach to waste and variability identification and elimination by stabilizing the work environment. Waste is easiest to detect and eliminate in a stable environment, as is pinpointing root causes of variability.  5S is a simple and immensely practical approach to improvement which can achieve great results in a very short period of time.

Many organizations typically begin their Lean journey with the deployment of 5S.  After the 5S has been firmly entrenched, they can move on to more advanced methodologies such as SMED, kanban pull scheduling systems, etc.

The following is a description of each of the 5S steps:

The 5S Steps

1st S       Sort

In the Sort step, necessary items for the workplace are separated from unnecessary items and subsequently removed.  A “red tag” campaign is conducted to evaluate items based on their usefulness and frequency of use.  Unnecessary items crowd the workplace and make it difficult to find and keep important items near the work area.  These items include obsolete equipment, broken tools, obsolete inventory, scrap, old files, etc.  Safety and productivity are improved as a result of the extra floor space created.

2nd S      Set-in-Order

The 2nd S involves installing systems whereby necessary items are always located in logically predetermined locations.  Based on the inventory classification of the red tag campaign, items are placed in locations based on frequency of use.  Frequently used items are placed at or near the workplace while infrequently used items are stored in specified locations.  When items are stored in logical places time is not wasted looking for the appropriate tools or fixtures.  The “gold standard” for the 2nd S is a workplace organized such that needed items can be retrieved within 30 seconds with a minimal number of steps.

3rd S – Shine

The 3rd S consists of the carrying out of regular cleaning activities that ensure that machine downtime is minimized by keeping the factory dirt and dust free and the machines properly maintained. Observers are always amazed when they see how incredibly clean the shop floors are of world-class Japanese manufacturing plants.  Daily cleaning of machines and production areas results in a dust and dirt free factory which reduces breakdowns and maintenance costs while improving safety and quality.

4th S – Standardize 

The goal of the 4th S is to maintain and entrench and the first 3S’s via standardization. This is achieved by the providing of easily understood visual warnings as well as standardized work methods and procedures.  Equipment is marked and labeled so that observation and inspection of equipment can be conducted easily and uniformly.  Anyone on the shop floor, not just the actual operator, should be able to determine when a machine or other piece of equipment is malfunctioning.  As a result, determining the condition and status of equipment becomes accurate and easy and responsiveness increases.  Reaction time to malfunctions is reduced resulting in reduced downtime.  Standardized procedures result in the most efficient use of resources as only the most efficient practices are followed.

5th S – Sustain

The 5th S  involves developing habits to entrench the 5Ss on an individual basis.  5S must become a way of life, and not just another “quick fix” program. The key tool for this entrenchment is a detailed regular appraisal of the workplace called the “5S Audit”.  The audit ensures that the 5S program continues indefinitely and a return to old habits does not occur.

It’s clear that 5S is much more than just a “housekeeping” program.  It is a structured program that results in dramatic changes and equally dramatic results.  Improvements between manufacturing plants where none of the 5S practices are in place, and plants with a full 5S environment, have been noted as:

Quality                                                              90 percent;

Productivity                                                     15-20 percent;

WIP Reduction                                                50-80 percent;

Increase in Space                                           30-40 percent;

Accident Reduction                                       90 percent;

Non-Value Added Time Reduction             25 percent

 

A Wisconsin manufacturer of park benches, ash cans, and bicycle racks achieved significant benefits through their 5S implementation.   Setup times were cut by up to half an hour, and lead times by three to six weeks, without much time and money.  Employees noticed the difference. “Things flow a lot easier now,” according to the plant manager, “I can always find my tools.  I love it.”

For any of the tools in the toolkit for becoming lean – quick changeover, total productive maintenance, mistake-proofing, and so on – 5S significantly helps in both the implementation and sustaining of improvements. By implementing 5S, one steel mill for example, improved floorspace and organization on the shop floor.  This cut its setup time from 12 to 16 hours down to two hours.

But 5S isn’t just for the shop floor.  Traditionally 5S methodology has been used in manufacturing companies, but service organizations such as banks, hotels, courier services, and IT-enabled services are now utilizing this approach. Think about it: in a typical day in the office how much time do you waste searching for information, looking for computer files, and walking back and forth to the printer to retrieve a printout or fax?  Are there mistakes being made because you have inaccurate or outdated information?  The 5S themes of organization, standardization are universally applicable to all work environments. Successful companies such as Parker Hannifin began their Office Lean initiatives by first undertaking 5S programs.

Where should 5S be applied?  The answer is in all industries and all departments – it can and should be applied everywhere.   Successful North American implementations include stamping operations, injection molding plants, steel mills and beverage manufacturers.  And as mentioned above, it’s applicable in all functions of the enterprise, not just on the shop floor.

For companies that have limited operating expenses, 5S gives them a high return on investment and immediate payback.  Before implementing any improvement approach such as Lean/Six Sigma, organizations should implement and institutionalize 5S.  By doing this, the likelihood of your continuous improvement efforts succeeding is greatly increased, as you have obtained buy-in at all levels of the organization.     5S creates the basis for Lean thinking.  By getting the workplace under control, by waste can be more easily identified and eliminated.  Root causes of process variability will also become more visible. Finally, implementing 5S will help you get some significant “quick wins” that will help build momentum for your continuous improvement program.

Lean Laggards Article Published / The Importance of Effort Alignment

I hope everyone is having a great holiday!   First a heads-up that the article I referred to in my previous post, “Lean Laggards” has been published in the December 2017 issue of Pharmaceutical Manufacturing.   If you didn’t read my last post, this is an article updating how the Pharma industry has progressed in the last 5 years or so in terms of becoming more “lean” and is a sequel of sorts to a previous article written some years ago.   While lean programs have become an increasingly popular approach to addressing key strategic challenges in the pharma industry, including greater throughput, higher quality and reduced costs, unfortunately the industry has seen little overall progress.   This article explores the root causes of why this has occurred and how it can be addressed.

Speaking of root causes, a recent conversation I had with a colleague prompted me to share a story and a key learning about the importance of spending enough time upfront before beginning an improvement effort before starting.   Some years ago I had a job interview with a company that specialized in Lean/Six Sigma implementations.  One of the interview questions I was asked was, “Which phase of DMAIC (“Define/Measure/Analyze/Improve/Control”) is most important?”

For those not familiar with the term, DMAIC is Six Sigma’s core improvement methodology.   Essentially you define the problem (“Define”), determine the baseline of the current state (“Measure”), identify, validate and select the root cause(s) to resolve (“Analyze”), test and implement solutions (“Improve”), and finally ensure that metrics are in place to monitor the improvement and ensure sustainability (“Control”).

My answer to the interview question was “Define.”   More than a decade later my answer has not changed.  In fact, I am even more certain.  What I have seen a number of times in my career is the lack of adequate time spent upfront prior to beginning improvement efforts on defining just what exactly what is intended to be accomplished (“Where are we going?”), and aligning key stakeholders on the goals/objectives and plan (“How do we intend to get there?”)

The results of not taking the proper steps to ensure success with the above can be at best loss of time/money and at worst, a failed project.

There’s an old expression I was taught when I first started consulting: “If you don’t know where you’re going, any road will take you there.”

Before starting an improvement effort it needs to be clearly and precisely defined just what precisely do you intend to accomplish?   I can recall a number of times where I’ve talked to someone at a company undertaking one of these efforts and one of the first questions I ask is, “What do you intend to accomplish with this project?”  I can’t tell you how many times I’ve heard, “to improve,” or “get better.”  Those times where there is a more specific answer such as “improve quality” or “change our culture” I then ask, “Okay, so what exactly does that mean?  How will you measure the change?”

If you can’t clearly and precisely define where you want to go and how you will measure progress you need to do more work upfront before starting.  Another challenge I see all too often is that different stakeholders have different opinions on what “success” looks like.   This is a recipe for disaster!

So what should be done to avoid these issues?  One great tool to use is a project charter.  The process of creating a charter and putting words on paper will force a clear articulation of the challenge to be resolved.   The charter should be discussed with every key stakeholder to ensure alignment.   If you don’t have alignment, don’t proceed with the project!   Spend the time upfront via alignment workshops.  It will take more time on the front end, but you will save time/money and reduce the risk of failure.

Food for thought on this for those who are in the process of undertaking improvement efforts such as Lean, Lean/Six Sigma, Operational Excellence, etc:  if asked what defines “success” for these efforts, would everyone in your organization give the same answer?  Of key importance: are your leaders all aligned?

“Lean Laggards” – Upcoming Article on Lean Progress in the Pharma Industry

A heads up that I have an article due for publication in the December issue of “Pharmaceutical Manufacturing” updating how the Pharma industry has progressed in the last 5 years or so in terms of becoming more “lean.”

This is a sequel of sorts to the article I wrote some years ago on the same topic.  Despite all the published case studies and conferences dedicated to this topic, the degree of progress (or lack thereof) is likely to be surprising to many.   This article will show how this lack of progress is evidenced in the trend of pharma company inventory turns, and detail the root causes for the stagnation, and in some cases, regression.

I am in the progress of writing a follow-up article due for publication in the first quarter of 2018 that will detail an approach to address these root causes.

One other note of interest:  in the course of writing this article I conducted some research on the progress of non-Pharma companies in terms of becoming more “lean.”  The results were surprising.  

Hope this is of interest.

Simple Solutions for Complex Problems

Have you ever heard of Derreck Kayongo?  I had not until I began reading a book published recently called “Visual Intelligence.”   According to the book, the author, Amy Herman, has taught the FBI, the State Department, Fortune 500 companies, and the military how to hone their “visual intelligence,” which is described as the ability to better see and understand details of what’s going on around you.

There’s an anecdote in the book about Derreck Kayongo.  Kyongo was born in Uganda just as Idi Amin’s dictatorship began.  As violence spread through the country and civil war erupted, Kayongo and his family became refugees in Kenya. He later immigrated to America to attend university.

On his first day in America, Derreck Kayongo was preparing to take a shower in his hotel when he discovered the many different kinds of soap in his room: hand soap, face soap, body soap, shampoo, conditioner. He had never seen so much soap for one person! After a few days, he began to wonder what happened to the partially used soap that disappeared from his room each day.   Unlike the slivers of soap used in the African refugee camps he had grown up in, the bar from his shower was fairly substantial; it seemed almost brand new after he had used it.

He asked the concierge what happened to the old bars and was shocked to hear they were thrown away.    In Kayongo’s mind this was a waste no one could afford, not when he knew more than two million people, most of them toddlers, still died every year from diarrheal disease, a condition that was easily prevented by washing one’s hands with soap.   Soap was a luxury item in Africa that many could not afford, yet in America it was simply thrown away.   Kayongo then decided to try to do something with what he found to help his old country:  he drove to local hotels and asked if he could have their used soap.

Kayongo found a recycling facility to scrape, melt and disinfect the bars of soap he collected.  He and his wife Sarah eventually created a life-changing international aid organization that collects discarded soap from hotels, reprocesses it and distributes it to vulnerable populations worldwide. This simple idea fights the #1 killers of children in many at-risk communities: hygiene-related diseases. Active in 32 countries, Global Soap has given millions of bars of soap to refugees and people affected by natural disasters like the earthquakes in Haiti and Nepal. Global Soap recently partnered with Clean the World. These organizations have contributed to an amazing 30% reduction in child deaths, globally, since 2009 and are expanding Kayongo’s original vision to include micro-loans and training for soap makers in communities around the world. In fact, the city of Atlanta designated May 5 as annual Global Soap Project Day.

What do we learn from this story?  Solutions to difficult problems can come from being able to really see and paying attention to details that you may often go unnoticed.

Accelerating Continuous Improvement Initiatives: Applying Lean, Six Sigma and TOC to Program and Project Management

In the last post, I provided a link to an article I wrote some time ago on how to utilize TOC to focus Lean / Six Sigma improvement efforts.   If you haven’t already, I recommend reading that article as it provides a good overview of Lean, Six Sigma, TOC and how they can best work together to maximize value.

The problem of these types of programs not being successful or not achieving their maximum potential value continues today.   In this article, I discuss principles to ensure that your program is successful.  I recognize that some of these principles, such as “Top management must be committed and actively involved” are much easier said than done.   In fact, my most recent thinking is that the issue of top management commitment is at the top of the list as to why these initiatives aren’t nearly as successful as they could be.    In my view, this area needs to be focused upon in more detail in terms of what CI practitioners can practically do to get this commitment and involvement.

In order to address this problem, we need to understand what is the root cause.   From recent discussions with Richard Schonberger, a leading lean advocate, these types of initiatives may not be viewed as “strategic” enough to warrant continued senior management attention and commitment.   From what I’ve seen, there appears to be a lack of understanding of how lean and Six Sigma can be utilized to drive strategic benefits.   One theme that I’ve consistently seen is that of these programs being short term approaches to drive cost reduction.  This is a perception that needs to change if we want to be successful.

I’m currently writing an article that covers this topic in more detail, but I’m interested in your comments.

Where to focus improvement efforts? Using TOC (Theory of Constraints) with Lean/Six Sigma

In the previous blog post, I wrote about the challenge that arises once companies have decided they need to undertake improvement efforts, they frequently take on more improvement projects than they can handle.  I have seen this over and over again in my career, especially with companies that are starting Six Sigma efforts.    One of the success measures used is the number of certified “belted” practitioners.  In order to get certified, there is usually a requirement to undertake training and achieve results with a project.   As a result, the organization can take on projects that may not drive significant value, but drain the organization’s valuable capacity.

One approach to focus improvement efforts where they drive the most value is the Theory of Constraints.  I was lucky enough to be exposed to TOC when I started my career.   I wrote an article in 2006 that described what is TOC and how it can be used to enhance lean and Six Sigma efforts.    Take a look, and leave any comments you have below.

No time for improvement!

The following story was told to me when I first started in management consulting, over 25 years ago:

Once upon a time, a very strong woodcutter asked for a job in a timber merchant and he got it. The pay was really good and so were the work conditions. For those reasons, the woodcutter was determined to do his best.

His boss gave him an axe and showed him the area where he supposed to work.

The first day, the woodcutter brought 18 trees.

“Congratulations,” the boss said. “Go on that way!”

Very motivated by the boss words, the woodcutter tried harder the next day, but he could only bring 15 trees. The third day he tried even harder, but he could only bring 10 trees. Day after day he was bringing less and less trees.

“I must be losing my strength”, the woodcutter thought. He went to the boss and apologized, saying that he could not understand what was going on.

“When was the last time you sharpened your axe?” the boss asked.

“Sharpen? I had no time to sharpen my axe. I have been too busy trying to cut trees…”

One of the most common refrains I hear from clients is that they are “too busy” to engage in improvement initiatives.   Employees are already working overtime, how can we possibly ask them to engage in an improvement initiative?

WHY are they too busy?”   Many times it’s most likely because their “axes” (i.e., processes) never get sharpened.    I like to tell this story to clients and also add, “what happens if you don’t do anything at all?  Will things ever get better?  Or will they get worse?”

Another familiar refrain is, “I understand, but now isn’t a good time to do something.”   The thing is, it’s NEVER a good time!

Once you’ve agreed that you need to improve, the key questions become WHAT to improve and HOW to improve.  This is where many companies go wrong.   They take on too many improvement initiatives and as a result never get anything done.   I talk about this in the article I wrote some years ago, ““How Constraints Management Enhances Lean and Six Sigma.”   Every organization has limited capacity – FOCUS your improvement efforts on what’s important.

More on this topic in subsequent posts.

Inventory Turns Continued – Has Lean Progress Stagnated?

In the previous blog post, I stated, “What may surprise you even more is that it has become exceedingly difficult to find examples of companies that have demonstrated sustainable progress with lean.”

Hopefully that piqued your interest.   Again, before proceeding, please review the article I listed in the previous post, The Impact of Inventory Turns on Speed, Quality, and Costs to understand why the trend of inventory turns can be used a proxy to measure a company’s level of “leanness.”

Now that that’s been established, let’s look at how some of the companies are doing that are best known for their lean efforts.   If you do a Google search on “Top Lean companies” or similar words, you typically will get names that include the following:

Hewlett Packard
Wal-Mart
Caterpillar Inc.
Intel
Illinois Tool Works
Textron
Parker Hannafin
John Deere
Ford
Toyota

These companies are usually the ones you find listed as examples of what a successful Lean program would look like.   In the article that I wrote on the state of Lean in the pharma industry, I listed HP and Wal-Mart as examples of companies that Pharma could learn from.  Let’s revisit how things were at that time in these two specific cases:

  • HP has successfully applied Lean concepts with a number of case studies you can find online.  In the time period from 2000-2009, HP displayed significant improvement in inventory trends – inventory turns improved at an average rate of 6.9%.  HP’s upward trend translated directly into growth of free cash flow at a rate of 6.9% percent, with interest on the cash compounded over the 10 year period of lessening funds tied up in inventory.
  • At Wal-Mart, from 2000 to 2009, inventory turns improved at an average rate of 2.6% which translates directly into free cash flow improvement of the same rate.    Wal-Mart was able to transform an entire industry via their Lean improvement approach and dictate the requirements to successfully compete.

Now let’s take a look at the trend of inventory turns for HP and Wal-Mart, along with the other companies in the list above, in the period from 2009-2016.   All data was taken from Morningstar.com so blame them not me for any accuracies.

Inventory Turns Inventory Turns Inventory Turns Inventory Turns Inventory Turns Inventory Turns Inventory Turns Inventory Turns
Company Name 2009 2010 2011 2012 2013 2014 2015 2016
Hewlett Packard 12.50 15.26 13.98 13.38 13.97 13.62 12.19 7.15
Wal-Mart 8.79 9.00 9.08 8.70 8.34 8.08 8.11 8.06
Caterpillar Inc. 3.16 3.81 3.61 3.13 2.89 3.20 3.08 3.09
Intel 4.66 4.52 5.16 4.57 4.76 4.80 4.38 4.33
Illinois Tool Works 6.04 7.05 7.06 6.94 6.04 7.15 6.96 7.30
Textron 3.12 3.78 3.98 3.92 3.57 3.31 2.72 2.63
Parker Hannafin 5.95 6.47 7.27 7.08 7.26 7.41 7.23 7.13
John Deere 6.11 6.50 5.93 5.26 5.11 5.45 5.06 5.14
Ford 14.22 18.38 19.18 17.45 17.00 16.21 15.63 14.70
Toyota 11.27 11.58 12.19 11.20 11.17 11.52 10.83 10.77
Average 7.58 8.64 8.74 8.16 8.01 8.08 7.62 7.03

What do you notice in the data above?   Does ANY company show an upward trend in this time period?   Not one of them does.   It’s clear that lean progress has stagnated, and sometimes even regressed at these “lean leaders.”

Why has this happened?  More on that in the next post.   In the interim, please leave comments if you think you have any insights.
