• Tool Time Handbook 1.0 for Lean: by David P. Langford
  Co-authored by David P. Langford and Sarah Pavelka, this spiral bound handbook is an excellent resource. It is written in an easy-to-understand format with diagrams and explanations of 23 Lean Quality Improvement Tools and their suggested uses. You'll understand how Lean tools can successfully be applied to the 9 Step PDSA Improvement Process (Plan-Do-Study-Act Process). Our goal was simplicity. Each tool has a process explanation and is graphically represented. All of the Lean Quality Learning tools are also referenced to the 9 Step PDSA cycle for fast tool selection and implementation. This enables you to spend less time selecting tools and more time learning how, when and where to use them. Tool Time for Lean books are being used by students, administrators, board members, personnel staff, healthcare professionals, and business leaders, as well as by employees from schools, universities, corporations, hospitals, and government agencies.

• The New Economics: For Industry, Government, Education by W. Edwards Deming

• Management Matters: Building Enterprise Capability by John Hunter
  The book provides an overview for viewing management as a system. It is largely based on those of Dr. Deming, along with natural outgrowths or extensions of his ideas such as lean manufacturing and agile software development. To achieve great results there must be a continual focus on achieving results today and building enterprise capacity to maximize results over the long term. Managers have many management concepts, pactices and tools available to help them in this quest. The challenge is to create and continually build and improve a management system for the enterprise that leads to success. The book provides a framework for management thinking. With this framework the practices and tools can be applied to build enterprise capacity and improve efficiency and effectiveness.

• Evolutionary Operation: A Statistical Method for Process Improvement by George E. P. Box, Norman R. Draper
  Evolutionary Operation (EVOP), is a simple but powerful statistical tool with wide application in business. What originally motivated the introduction of EVOP, was the idea that the widespread and daily use of simple statistical design and analysis during routine production by process operatives themselves could reap enormous additional rewards.

• Understanding A3 Thinking: A Critical Component of Toyota's PDCA Management System by Art Smalley, Durward K. Sobek
  Winner of a 2009 Shingo Research and Professional Publication Prize. The A3 report has proven to be a key tool In Toyota’s successful move toward organizational efficiency, effectiveness, and improvement, especially within its engineering and R&D organizations. The power of the A3 report, however, derives not from the report itself, but rather from the development of the culture and mindset required for the implementation of the A3 system. In other words, A3 reports are not just an end product but are evidence of a powerful set of dynamics that is referred to as A3 Thinking.

Management Articles

• A Fun Presentation on a Powerful Software Test Design Approach by Justin Hunter
  "My own consistent experiences and formal studies indicate that pairwise, orthogonal array-based, and combinatorial test design approaches often lead to a doubling of tester productivity (as measured in defects found per tester hour) as compared to the far more prevalent practice in the software testing industry of selecting and documenting test cases by hand."

• Robust Experimental Strategies for Improving Upstream Productivity by Ronald D. Snee
  The solution to this problem is to use Lean principles to streamline the processes and procedures used to do the experimental work. Eliminating complexity and wasted time and effort results in experimentation being speeded up and scientists having more time to do creative work.

• Each necessary, but only jointly sufficient by John Allspaw
  "for complex systems: there is no root cause. ... Frankly, I think that this tendency to look for singular root causes also comes from how deeply entrenched modern science and engineering is with the tenets of reductionism. So I blame Newton and Descartes. ... In the same way that you shouldn’t ever have root cause 'human error', if you only have a single root cause, you haven’t dug deep enough."

• Keys to the Effective Use of the PDSA Improvement Cycle by John Hunter
  "The PDSA cycle is a learning cycle based on experiments. When using the PDSA cycle prediction of the results are important... The plan stage may well take 80% (or even more) of the effort on the first turn of the PDSA cycle in a new series. The Do stage may well take 80% of of the time - it usually doesn't take much effort (to just collect a bit of extra data) but it may take time for that data to be ready to collect."

• Small Business Guidebook to Quality Management
  The aim of this guidebook is to help small businesses make the transition to a quality culture. While the focus of the guidebook is small businesses the information is helpful to anyone transforming and continually improving their organization.

• Teaching Engineers Experimental Design with a Paper Helicopter by George E. P. Box
  "How a paper 'helicopter' made in a minute or so from 8 1/2' x 11' sheet of paper can be used to teach principles of experimental design including - conditions for validity of experimentation, randomization, blocking, the use of factorial and fractional factorial designs, and the management of experimentation."

• Standardized Work is a Goal To Work Toward, Not a Tool to Implement by Jeffrey Liker
  Standardized work is foundational to the Toyota Production System, yet remains one of the most misunderstood principles to outsiders. It is crucial to understand the true purpose of this foundational practice. Standardized work in the context of the Toyota Way refers to the most efficient and effective combination of people, material, and equipment to perform the work that is presently possible. “Presently possible” means it is today’s best-known way, which can be improved.

• The Scientific Context of Quality Improvement by George E. P. Box, Soren Bisgaard
  Scientific method is a key ingredient in the new philosophy of quality and productivity improvement. This paper provides an overview. A discussion of new ideas of how to design quality into products and processes is provided and Taguchi's work is evaluated.

• Analytical studies: a framework for quality improvement design and analysis by Lloyd Provost
  "An enumerative study is one in which action will be taken on the universe that was studied. An analytical study is one in which action will be taken on a cause system to improve the future performance of the system of interest. The aim of an enumerative study is estimation, while an analytical study focuses on prediction. Because of the temporal nature of improvement, the theory and methods for analytical studies are a critical component of the science of improvement."

• QFD: Past, Present, and Future by Yoji Akao
  "This paper reflects on the early days of QFD, the current status, and future challenges."

• Foundations For Transformation: Linking Purpose, People and Process by Mike Stoecklein
  "Nearly all organizations have attempted some type of company-wide improvement effort, and most managers and workers in organizations have experienced attempts to introduce and implement different management approaches. The experience for most people has been a series of programs (flavors of the month1) rather than the pursuit of a philosophy of improvement. We have observed predictable patterns in companies that pursue company-wide improvement from nearly all industries and share them in this paper. The foundations for transformation can be applied to not only business, but also government and education."

• Statistics as a Catalyst to Learning by Scientific Method by George E. P. Box

• The Principles of the Kanban Method by David Anderson
  Use the 5 Core Properties." 1. Visualize the workflow 2. Limit WIP 3. Manage Flow 4. Make Process Policies Explicit 5. Improve Collaboratively (using models & the scientific method)"

• Actionable Metrics by John Hunter
  "Metrics are valuable when they are actionable. Think about what will be done if certain results are shown by the data. If you can't think of actions you would take, it may be that metric is not worth tracking."

• Andon Cords at the Toyota Takaota Plant by Mark Graban
  "They pull the cord and a light flashes on an 'andon board' It tells the team leader which station has a problem (and music plays). Within seconds, a team leader (having two stripes on his hat) shows up to help. There is one team leader for every eight workers, on average (or 14% of their labor waiting for problems or responding to them)."

• Lean Knowledge Work
  by Bradley Staats and David M. Upton. "our research in IT, financial, engineering, and legal services reveals that such work can in fact benefit from the principles of the Toyota Production System. For one thing, a substantial amount of knowledge assumed to be tacit doesn’t have to be; it can be articulated and captured in writing if the organization makes the effort to pull it out of people’s heads. For another, all knowledge work includes some activities that have nothing to do with applying judgment and can be streamlined by training employees to continually find and root out waste. Even when knowledge is genuinely tacit, creating systems and rules to guide workers’ interactions can lead to more-effective collaboration."

• Dr. Demingʼs Camping Expedition
  "Asking why all the time is the most effect route to overcoming problems. "The only drawback to it Iʼve found is when youʼve needed only three whys to get to the root cause, some determined people still go on to ask two more. Or else they stop at the fifth, even if they havenʼt gotten to the root cause... Blinded by the quality tools and techniques, you have missed the completely obvious"

• Eight Reasons Retrospectives Fail by Esther Derby
  "Choosing Actions the Team Doesn’t Have Energy For... They may have tried before and failed, the task may be too difficult or time-consuming given the other work they have to do, or the work may be plain unpleasant. In any case, when the team doesn’t have energy to work on an improvement, chances are pretty good it won’t get done. Go with the task the team has the energy to complete."

• Teaching Quality Improvement by Quality Improvement in Teaching by Ian Hau
  This paper describes how students and the instructor worked as a team to improve the quality of teaching in a class. The defect rate dropped from 78% to 22% for computer instruction, 56% to 8% for blackboard presentation and 82% to 20% for overhead presentation.

• Are lean principles universal? by Michael Ballé
  "There is only one golden rule: we make people before we make parts. This requires a spirit of challenge, open mind and teamwork, as Pascal Dennis phrased it in his great lean novel Andy and Me. Every industry is different, but all human beings share the same capabilities and potentials – that is universal. As one Sensei once told me, the biggest room is the room for improvement."

• TPS vs. Lean and the Law of Unintended Consequences by Art Smalley
  "In every piece of TPS literature from Toyota, this stated aim is mixed in with the twin production principles of Just in Time (make and deliver the right part, in the right amount, at the right time), and Jidoka (build in quality at the process), as well as the notion of continuous improvement by standardization and elimination of waste in all operations to improve quality, cost, productivity, lead-time, safety, morale and other metrics as needed. This clear objective has not substantially changed since the first internal TPS training manual was drafted over thirty years ago."

• Lean Leadership Kaizen is Management by Mark Rosenthal
  "First they tried copying the benchmarked system on a small-scale test to deepen their understanding of what they had studied. Trying it on their parts surfaced differences that weren’t obvious at first, and they learned copying definitely wouldn’t work. Key: The reason they tried to copy was to learn more about it. This was a small-scale concept test, not an attempt at wholesale implementation... So, while an individual improvement task might take longer as people learn, in the end there is a multiplier effect as more and more people get better and better at making improvements. Sadly, it is really impossible to assign an ROI to that, so traditional management doesn’t allow for it..."

• Clearing Up Myths About the Deming Cycle by Ron Moen, Cliff Norman

But how to actually get their organization to adopt the ideas often confounds them..."

• A Fresh Look at Flow Charting by Tony Burns
  "The computer enables each symbol to be neatly aligned and connecting lines drawn clearly and simply...However, in using computer based flow charts, there may often be more negatives than benefits, as will be seen."

• The Art of Discovery by George E. P. Box, John Hunter
  Quotes by George Box in the video: “The scientific method is how we increase the rate at which we find things out.” “I think the quality revolution is nothing more, or less, than the dramatic expansion of the of scientific problem solving using informed observation and directed experimentation to find out more about the process, the product and the customer.” “Tapping into resources: Every operating system generates information that can be used to improve it. Everyone has creativity. Designed experiments can greatly increase the efficiency of experimentation."

• Doing More With Less in the Public Sector: A Progress Report from Madison, Wisconsin by William G. Hunter, Jan O'neill, Carol Wallen

  "He explained: 'Have you noticed that the Malaysia highways all use a much older, but cheaper version of noise absorbing wall?' Our team shook our heads. 'That's the problem. They can't afford this yet. It's true that our offering is superior to what the Malaysians are using, but economic reality is the reality that we live with.'"

• Why I dislike the name Six Sigma by Rafael Aguayo
  "Lack of management appreciation of the need for participation. Deming emphasized joy in work, teamwork and listening to your people. This seems to be totally lacking in Six Sigma. In fact major SS practitioners emphasize practices that will destroy teamwork, company cohesiveness and pride. ... Failure to appreciate the company as a system. Making improvements to one variable, such as material costs, can lead to higher labor costs. Lowering costs in one department can lead to higher costs overall for the company. These mistakes can be avoided if one understands the systemic nature of a company."

• Special Cause Signal Isn’t Proof A Special Cause Exists by John Hunter

• A3 Reports: Tool for Process Improvement by Durward K. Sobek, Cindy Jimmerson
  "Toyota uses it to systematically guide problem-solvers through a rigorous process, document the key outcomes of that process, and propose improvements. The tool is used so pervasively that it forms a keystone in Toyota's world-famous continuous improvement

• Using Poka-Yoke Techniques for Early Defect Detection
  "Poka-yoke devices fall into two major categories: prevention and detection. A prevention device engineers the process so that it is impossible to make a mistake at all. A classic example of a prevention device is the design of a 3.5 inch computer diskette.The diskette is carefully engineered to be slightly asymmetrical so that it will not fit into the disk drive in any orientation other than the correct one. Prevention devices remove the need to correct a mistake, since the user cannot make the mistake in the first place. A detection device signals the user when a mistake has been made, so that the user can quickly correct the problem. The small dish used at the Yamada Electric plant was a detection device; it alerted the worker when a spring had been forgotten. Detection devices typically warn the user of a problem, but they do not enforce the correction. ... [in software tesging] Unit testing and "smoke testing" [7] come closer to the notion of poka-yoke, in that they are located close to the source of the potential mistakes and the quick feedback they provide can keep mistakes from moving further along in the process."

• Practical Combinatorial Testing by Raghu Kacker, Rick Kuhn, Yu Lei
  "Combinatorial methods can help reduce the cost and increase the effectiveness of software testing for many applications. ... With the NASA application, for example, 67% of the failures were triggered by only a single parameter value, 93% by 2-way combinations, and 98% by 3-way combinations. The detection rate curves for the other applications studied are similar, reaching 100% detection with 4 to 6 way interactions."

• Using Design of Experiments as a Process Road Map by Davis Balestracci
  "The current design of experiments (DOE) renaissance seems to favor factorial designs and/or orthogonal arrays as a panacea. In my 25 years as a statistician, my clients have always found much more value in obtaining a process "road map" by generating the inherent response surface in a situation."

• How An Aeron Chair Gets Built Every 17 Seconds
  "At Herman Miller, they average 1,200 'plan-do-check acts'--that is, little proposed changes to the assembly process--ever year. ... A decade ago, an Aeron took more than 600 seconds in total to build. Today, it’s about 340. Meanwhile, safety metrics have improved by a factor of 6. Quality metrics have improved by a factor of 10. A single Aeron takes one fifth of the labor to make that it once did. The actual factory itself is 10 times smaller. Today, Herman Miller is doing far more with the same labor force that was once producing a sum total of five different office chairs. Today, they produce 17, using roughly the same number of people. And all the while, lead times have shrunk from two months to as little as 10 days." "
