About the Author

About the Author of Gemba kaizen

Masaaki Imai (1930–2023), author of Gemba Kaizen: A Commonsense, Low-Cost Approach to Management, was a globally recognized management consultant and Lean manufacturing pioneer. A leading authority on operational excellence, Imai founded the Kaizen Institute in 1985, establishing himself as the foremost evangelist of the Kaizen philosophy—continuous, incremental improvement grounded in workplace-level problem-solving. His 1986 bestseller Kaizen: The Key to Japan’s Competitive Success introduced Lean principles to Western audiences four years before the term “Lean production” gained prominence, selling over 300,000 copies across 16 languages.

Trained at the University of Tokyo, Imai’s methodologies emerged from collaborations with Toyota visionaries like Taichi Ohno, shaping frameworks adopted by Fortune 500 firms and manufacturing giants. His work earned accolades including the Shingo Prize and Asia-Pacific Human Resource Development Award.

Imai’s final book, Strategic KAIZEN™ (2021), completed his trilogy on organizational improvement. Gemba Kaizen remains a foundational text in industrial engineering and process optimization, detailing 21 low-cost techniques to boost productivity and quality. Translated into 14 languages, it has guided lean transformations in over 30 countries through Imai’s consulting network.

Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!

@ladyInfinity

I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.

@jayallen

The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.

@Raguipa

What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.

@colonyofcreatorsNGO

I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.

@BeFreed user

It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.

@austinakon

I love this app. Used it for several days and I cannot stop listening. Such a great way to start.

@jcrules328

I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.

@DanielCZ

I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.

@BeFreed user

I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.

@Brad

I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!

@BeFreed user

The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.

@jayallen

BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.

@BeFreed user

At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!

@matteo77

BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
