This was a very easy read, and a good introduction to understanding the need for continual improvement.

I'd like to give it to many people in my company.

The last half of the book is filled with case studies. It seemed that only 2 or three seemed directly applicable to my work, but most did have a least one or two ideas or examples that were general enough to be applicable. The use cases were a bit repetitive, but I suppose that this repetitiveness helps in burning the concepts into your mind.

Overall I think this book has some good, badly organized content and a lot of publicity.

This book is divided in two parts. A first part, where all the concepts are explained, and a second part, where some examples and case studies are highlighted.

The first part contains a lot of Kaizen concepts well explained - so if you are looking to learn more about Kaizen and lean this book is for you. However, all the concepts lack a transversal framework that groups everything together. It felt that the concepts and methods were explained in a laundry list format.

The second part provides a gigantic laundry list of case examples of how companies were successful implementing Kaizen methodologies and tools. In my opinion it misses a guiding line between all the case studies since the book only focuses in describing the biggest number of success stories it can. It felt like a 200 page appendix of publicity about how good Kaizen is. It misses a framework at the beginning stating why these success stories were chosen in favor of others and, better even, they should have been merger with the concepts of the first part to give light on the concepts being explain, to function as explanatory examples for the methods. Also, the book has a lot of 1-page images and frameworks that, in my opinion, don't bring that much value.

All in all, I think this could have been a killer book, if written in 200 pages (instead of 400), with a good overall framework for all kaizen concepts and the success stories used as supporting evidence for the methodologies (and not as a laundry list of show-off).

Nevertheless, the book touches on the following good material

1) Major Kaizen Systems
a) Total Quality Control (TQC)
b) Total Quality Management (TQM)
c) Total Productive Maintenance (TPM)
d) Policy deployment
e) A suggestion system
f) Small-group activities

2) The House of Gemba

3) Five A (5S) of Good Housekeeping
a) Sort (Seiri)
b) Straighten (Seiton)
c) Scrub (Seiso)
d) Systematize (Seiketsu)
e) Standardize (Shitsuke)

4) Productivity Improvement
a) Improve quality
b) Improve productivity
c) Reduce inventory
d) Shorten the production line
e) Reduce machine downtime (SMED tool)
f) Reduce space
g) Reduce lead time

5) Muda
a) Overproduction
b) Inventory
c) Defects
d) Motion
e) Processing
f) Waiting
g) Transport

6) Golden Rules of Gemba
a) When a problem (abnormality) arises, go to the gemba first
b) Check the gembutsu ("relevant objects")
c) Take temporary countermeasures on the spot
d) Find the root cause
e) Standardize to prevent recurrence

7) Standards

8) Muda (waste), Mura (variation), Muri (overburden)

9) Visual Management in the Five Ms
a) Manpower (operations)
b) Machines
c) Materials
d) Methods
e) Measurements

10) From Just-in-Time to Total Flow Management
a) Takt time vs. cycle time
b) push production vs. pull production
c) Establishing production flow
d) Benefits: i) cost reduction, ii) working capital reduction, iii) increased productivity, iv) increased quality, v) increased customer service and satisfaction

11) The CEO role in Kaizen

Overview:
"Gemba Kaizen" by Masaaki Imai presents an incisive exploration of the principles and practices of Kaizen, emphasizing continuous improvement through practical, low-cost strategies. The term "Gemba" refers to the actual place where work is done, and the book underscores the importance of making improvements directly at the source.

Content:
Imai outlines the foundational concepts of Kaizen, focusing on the need for a mindset shift towards constant, incremental improvement. The book delves into the practical applications of Kaizen in various business environments, illustrating how even small changes can lead to significant enhancements in productivity, quality, and efficiency.

Strengths:

Practical Examples: The author provides numerous real-world examples and case studies that illustrate the successful implementation of Kaizen.
Accessibility: The approach is designed to be low-cost and commonsense, making it accessible to organizations of all sizes.
Focus on People: Imai emphasizes the role of employees at all levels, advocating for their involvement and empowerment in the improvement process.

Weaknesses:

Repetition: The book tends to reiterate the same points, which can be tiresome and redundant for readers seeking concise information.
Lack of Depth: While it offers a broad overview, the book sometimes lacks depth in its exploration of more complex Kaizen techniques and tools.
Conclusion:
"Gemba Kaizen" serves as a valuable introduction to the principles of Kaizen, especially for those new to the concept. However, for seasoned practitioners, the content might seem overly simplistic and repetitive. The book's strength lies in its practical, down-to-earth advice, though it falls short in providing in-depth, advanced insights for more experienced professionals.

Note:
While "Gemba Kaizen" presents useful guidelines for low-cost management improvements, its tendency to repeat key concepts can be frustrating. The book is a solid starting point but requires supplementation with more detailed texts for those seeking comprehensive mastery of Kaizen practices.

This book’s interesting title spawns from the Japanese language, which serves as the nomenclature for the essential concepts conveyed in this text. This book communicates the concept of management which grew out of Japan, was popularized in the 1980s, and served as the philosophy for companies like Toyota. Management texts like this and Deming’s famous fourteen points taught and continue to teach the international business community about running better businesses.

The philosophy of this work is simple. Instead of focusing on goal-achievement (as many in the West have), workers should focus on continual improvement (the kaizen) of their work practices (the gemba). Each day, they should try to eliminate some wasted energy or product from their work (the muda). I find this philosophy more congruent with my understanding of my work in the sciences and in research. It facilitates open-ended work instead of predefined (and often constricting) goals.

Although the concepts are commonplace in leading American businesses today, the nomenclature was introduced to me from a group at the University of Alabama at Birmingham who use it to manage their medical center. After 200 pages of theory, this book also contains about 200 additional pages of use cases where these concepts are applied to many businesses in many different situations across many continents. It is relevant to areas as disperse as manufacturing, medical practice, and software development.

A lot of the concepts in these management books have always struck me as fairly obvious: yes, quality is important. Prioritize quality over other concerns because you need to be competitive on the market. Be specific when giving feedback and setting goals. Involve all relevant stakeholders to contribute ideas for continuous improvement, etc. Hard to argue with any of that. However, I did enjoy some of the specific examples Imai has in this book, such as the one about the water in the hot spring resort. Question data and find the true root cause of an issue.

The tenets of "gemba" are similar to user research and user-centered design, areas that became more popular after this book was published in '97. Yes, it makes sense to actually do real user research, such as ethnography, as opposed to sitting around in meetings and theorizing. But the application of this "gemba" approach isn't without issues. In one example, a company decides that knocking down its walls and forcing everyone into an "open-concept office" is the way to go because of "gemba" and one employee complains that it would be "too noisy." This, I think, is a valid complaint. We have seen more recently that open-concept offices have their own issues.

I agree that standardization is generally good and should be done, where possible, but I also believe that it is a lot more possible and practical to accomplish it in manufacturing.

Goes a bit overkill on all the case studies at the end, IMO. That could have been trimmed.

Recommended for anyone in big corporations or government who's looking for a method and philosophy to create structural change for quality and efficiency.

"Kaizen" means continual improvement, and "Gemba" means the workplace - so basically, it means bringing continuous improvement for the better at a workplace. So not only we should look at operation and innovation, but there needs to be a space there for Kaizen (to improve existing processes and products).

For this to work, we need to get rid of or reduce "Muda", which means wastes.

It's interesting to see there are many touchpoints and matrics that can be monitored and optimized. Example of Muda: transportation time, waiting time, duration of downtime, production time, movement distance...etc. By reducing those waste, we become more efficient.

Cost-reduction and quality improvement go hand in hand, not one without the other. Track and reduce the Muda, keep improving the processes from pre to post-production, and have a QA system to monitor throughout.

Awalnya saya pikir buku ini sama persis dengan Strategic Kaizen, ternyata ada bedanya. Masih menggunakan inti dari kaizen perihal elimination hal-hal yang tidak perlu di tempat kerja (Gemba), berikut pengetahuan tambahan dari buku ini:

1. Penerapan standard kerja yang fleksibel membantu perusahaan lebih berkembang.
2. Disiplin diri membantu menciptakan dan mempertahankan efisiensi, dalam buku ini diceritakan tentang 5S kaizen yang sudah sering kita dengar.
3. Manajemen visual adalah alat yang murah, masuk akal, dan memungkinkan kita menghemat waktu dalam memecahkan masalah pada lingkungan kerja yang semakin kompleks, sekaligus motivasi karyawan secara lebih kuat.
4. Gemba Kaizen adalah pola pikir, harus dilakukan oleh pimpinan perusahaan, dan dilakukan sedemikian rupa sehingga memberikan contoh yang baik bagi karyawan.
5. Manajer yang baik bekerja di tengah-tengah Gemba, mereka akan lebih mengenal pekerjanya dan kedua belah pihak akan lebih percaya satu sama lain.

Buku ini jadi semacam gabungan Kaizen + 4DX.

4-4.5 stars
It's a very clear depiction of both concepts: gemba gembutsu & kaizen.

Very structured, directly referring to whole knowledge base accumulated by kaizen practitioners across Japanese industry leader companies - though very credible. It's focus on typical production companies (as kaizen originated there), but 80-90% of ideas can be directly applied in other industries as well.

Why not 5 stars then? Because it's a rating of a book, not of a method. Book itself is very dry, even with all the examples - in fact ~40% of the book (final part) consists of cases, but they are very far from being inspiring or even just interesting. Maybe it was me being tired with the topic, but I think that going for count instead of quality (pleeenty of cases here) didn't help here.

But anyway - if you're interested in Kaizen and/or Toyota Way, plus you're not afraid of manufacturing industrial specifics, that book is truly a decent read.

Excellent learning book!

This book explains most of the concepts in a very simple way. There are maybe a little too many references, although some of them are really excellent are good learning examples.
Excellent book nevertheless!

This books give you a good introduction into Kaizen and the results when you apply it into your organization. With all the different case studies (Kaizen stories) as a reader I can see how different industries can take advantage of Kaizen. I recommend every upper management to read this to change the perspective towards the way work is handled, people are treated and profit maximization.

A good place to start when learning about the Kaizen philosophy. It's top level, and does not go deep on the processes, though i think each of them deserves their own book.

I highly recommend, and i believe the ideas are applicable in all kinds of businesses and situations. Even for maintaining a kaizen way of life. :)
