Lean Production - Review written on December 16, 2007

"I have visited hundreds of companies and taught employees from over one thousand companies. I have compared notes with many of those I have taught. I have also visted a number of the U.S plants that were fortunate to have received assistance from TSSC, which has consistently helped companies achive a level of improvement like "Lean Company X". Unfortunately, I see a persistent trend in the inability of these companies to implement TPS and lean. Over time, the lean production line TSSC sets up degrades rather than improves...There is a "lean production cell" here and a pull system there and the time it takes to changeover a press to a new product has been reduced, but there is where the resemblance to an actual Toyota lean model ends."
Why has American Automotive technology slow to adopt the Toyota Way? Three forces: political protectism, cheap resources, and well established marketing channels. However, as fuel prices continue to escalate, innovative automotive solutions will be rewarded and brand will have less loyality. Toyota claims that their line workers are among the best and brightest minds and their ideas are used to solve problems.
TPS has potential. TPS advocates continual learning through eliminating waste, remove unnecessary labor, to see for yourself and understand the situation, and making decisions slowly by consensus. A circular cycle of gathering information and thinking about the completeness of the problem. All things must be considered in the model. Respect for people: leaders a mentored in the TPS system; TPS challenges employees to develop skills, verbalize ideas and innovations, be loyal to the company, and work in small teams. TPS weakness is that they listen and choose a leader basis on reputation and not merit. A well connected and respect leader has great pull in the organization. A brillant young leader has a difficult time rising to the top without sponsership.
The TPS system is focuses on process and uses a vast number of tools to surface problems. A number of techniques help expose problems, such as, pull systems where the one product at a time is completely built and any error in the process will stop the whole factory. The immediately identification of the problems is brought to the foremost attention of everyone in the plant. TPS process assists external processes, for example after one of the earthquakes, a major parts supplier was offline and Toyota used this supplier exclusive, for parts. Toyota sent 300 engineers to help get the company online.
TPS levels out workload, reduces overtime, and promotes happier employees through empowerment. Tasks are standardized for continueous improvement.
Visual controls are used so problems do not hide, inventory build up, and waste go unnoticed. TPS uses reliable and tested technology. Japan uses four times as many robots as the US. The automated factory has been both a cost saver and a production gainer for Japanese companies. TPS works to establish long term goals. One weakness of TPS long term goal planning is that the consumer never know about it.
In TPS information can use internal and external information given by the consumer; more consumer participation and involvement in the company is encouraged. The phrase "Oh what a feeling, Toyota" should mean the consumer is content with the long term goals and planning provided by Toyota and the consumer plans on support the future by investing in Toyota through purchases.
"Operational efficiency by itself canbe dangerous. Think of the Swiss companies that were so efficient in making mechanical watches yet are now out of business."
"Kaizen teaches individuals skills for working effectively in small groups, solving problems, documenting and improving processes, colling and analyzing data, and self-managing within a peer group. It pushes the decision making down to th workers and requires open discussion and group consensus before implementing a decision." Kaizen takes a strong commitment by senior management, so that individuals can participate effectively without fear. TPS creates "a new way in manufacturing or service delivery - a new way of seeing, understanding, and intrepreting what is happening in a production process, that could propel them beyond the mass production." Lean production focused on speed in the supply chain by "shortening the lead time by eliminating waste in each step of a process leads to best quality and lowest cost, while improving safety and morale."
The first question TPS asks is, "what does the customer want"? The question is directed at both the internal and external customer.
According to TPS there are eight types of waste: Overproduction, Waiting, Unnecessary transport or conveyance, overprocessing or incorrect processing, excess inventory, unnecessary movement, defects, and unused employee creativity. Ohno said, "Every method available for man-hour reduction must, of course, be pursued vigorously; but we must never forget that safety is the foundation of all our activities." There are times improvement will compromise safety. In that case start over and take another look at the operation. "Never be satisified with inaction". Jikodka or in-station quality allows separates the person from the machine. Now the individual is free to be creative and observe improvement. Respect for the individual improves morale and brings more ideas into materialization. Just in Time technology employees pull technology and reduces excess inventory.
Excellent Book On The Toyota Way And Lean Manufacturing! - Review written on September 07, 2007

Jeffrey Liker clearly knows what he writes about. The book is the result of more than a decade of study, on site visits and interviews with several Toyota key people. It describes 14 toyota principles, which go through the Toyota Philosophy, the Toyota Production System, the relationship with employeees, customers, suppliers and partners, and a focus on continuous improvement. No wonder Toyota is one of world top most admired companies!
Very interesting is also the Japanese management principles and mindset - slow but determined, patient, self-reflection, learning by actuall observation and doing, consensus seeking, and managing for the long term.
By coincidence, yesterday (6/Sep/2007) the news came up that Jim Press (American Toyota President)was hired by Chrysler - I can imagine why.

Knowing all the lean tools and having implemented many of them, there still seems to be something missing. While this book discusses the Lean tools, it also discusses what makes them effective. It discusses, the history, mindset, and environment that created and made Lean Manufacturing today.
This book is not for the Lean Champion but for the CEO, the Divisional VP, the Plant Manager, especially in those situations where Lean just has not or is not living up to the expectations.
Good introduction -- but all pros and no cons? - Review written on December 28, 2006
Rating: 4 out of 5
Since the author is a professor, I'd originally hoped for a balanced coverage. But the book did not explore the shortcomings of The Toyota Way. Knowing both the pros and cons would have given us a much deeper understanding.
For example, the American auto companies are still in business long after Japanese cars surpassed American cars in quality -- so the American companies must have done something right, too, like inventing the minivan and SUV markets. Therefore, there's got to be some strategic shortcomings of The Toyota Way.
Another example... the book's case study of the new Sienna minivan is not such a shining example, in my opinion. The chief engineer has to drive across North America to discover the advantage of having multiple cup holders??? American cars/vans have had that feature for years! He had to observe the loading of wood planks into a Honda Odyssey to be convinced for the large body size??? Then "The Honda Way" was already better than "The Toyota Way", and in any case, all American vans/trucks have had the size advantage for decades! Besides, reading an issue of The Consumer Report magazine could give you the same info. So, the question is not how "The Toyota Way" helped discovering those good features in the car, but why it took so long?
Despite the above, I think this is a great book that clearly articulated The Toyota Way from technique to philosophy. Recommended!

As you can check the 4Ps and the 14 management principles typed by some reviewers here, most of them are just common sense. However, common sense is really not that common, at least not in the auto industry when one sees the high failure rate, even amongst Japanese auto makers who copy some but not all of the Toyota Way or Toyota Production System TPS. Thanks to the author, many good samples are vividly written of how Toyota fully commits to its long term principles at the expense of short term benefits, respects the communities where its factories locate, supports even the lowest of worker to quality/value devotion (Dare you stop the whole production line for a minor fault you find? They encourage you to do so in Toyota). I am sure many ordinary but top level managers will excuse themselves from the level of Toyota committment on unique circumstances. In Toyota, they ask themselves "why" five times on each problem to nail its root cause, instead of taking anything for granted, as those ordinary managers do. Moreover, Toyota had invested/devoted much to adapt to the cultural, social....difference between Japan and US. Add them all up, that's the difference between survival and death.
I had read many business books of the HBR type. However, if I am asked to make only one recommendation, this is it.

Liker's "The Toyota Way" provides a good introduction for someone not familiar with "lean production" or "The Toyota Production System (TPS)." On the other hand, I prefer the materials written by Tachii Ohno and Shigeo Shingo (Toyota Production System developers) for their greater clarity (if you excuse the sometimes labored translations) and detail.
Liker begins by pointing out that in the 1980s it became clear that Japanese cars were lasting longer than American models and required less repair. (They were also cheaper to build - even if you ignored lower labor costs.) Toyota's profit for FY '03 exceeded G.M., Ford, and Chrysler - combined! Toyota has the fastest product development process in the world.
Key to the TPS is a commitment to continuous improvement, directed at "adding value." Adding value, however, is defined from the customers' point of view - specifically excluded are activities such as overproduction (creates unneeded transport, tracking, and storage space needs; also increases risks of obsolescence and quality problems), waiting (eg. watching a machine, lack of parts, bottlenecks, downtime - perhaps for line changeover), transportation, defects, and searching (eg. parts, and paperwork - retrieving, or finding the required information within it). Liker also reports that most processes are about 90% non-value-added (waste); if one focuses on value-added "process-time", the proportion of waste is usually much higher.
Keys to eliminating/reducing these problems include continuous flow (one-piece production cells), stopping to immediately fix problems, fast changeover (eg. easy line modification for alternative models), using visual control (eg. marked inventory boundaries, alarm lights), use of "pull" systems and "kanban" to eliminate overproduction (without complex computer systems), helping (and standardizing) suppliers, asking "Why?" five times when a problem arises to ensure correction of "root causes" in a manner that helps other areas as well (eg. why the puddle (oil leak), why the oil leak (gasket problem), why the gasket problem (wrong specifications), why wrong specifications (Purchasing Dept. focus on initial acquisition price), why Purchasing Dept. mis-focus (wrong reward critia) --> correct underlying problems so that does not continually recur), eliminating variation (eg. reduce suppliers, tighter tolerances).
Liker points out that American supermarkets provided Ohno with the idea for the TPS "pull" system (emptying of product space by customers results in a visual cue for staff to restock and reorder).
