At recent moment, I found a term for OPL for TPM which I am not so familiar. Therefore, I dig out some information and summarized as below to keep a reference, share with my readers.
What is OPL?
OPL is the short term of One Point Lesson. A TPM one point lesson is just one of the many tools that can be used to improve knowledge and understanding of the condition and performance of an asset on a day-to-day basis. The approach engages the front-line operations and technicians and encourages them to get involved in the continuous improvement of the asset. By simply passing on good ideas, maintenance interventions can be optimised to ensure there maximum impact on either the performance or condition of the assets. The benefits for implement OPL for workshop are summarized as below,
* Communicates knowledge and skill about the asset amongst members of the team.
* Raises the knowledge and skills of the team in a very short period of time.
* Is used for eliminating problems and for making improvements to the way of working.
* Makes sure that everyone knows about a better way of doing something.
* Makes sure that next time a problem is encountered everyone knows the way to solve it.
Here is the flow of running OPL,
1. One member of the team prepares a sheet, which describes the problem and solution in simple language. It is often illustrated with pictures if possible.
2. The team discuss the 1-point lesson, formally or informally, and incorporate any ideas.
3. The 1-point lesson is approved by the line management to ensure it is appropriate and safe.
4. The 1-point lesson is then published and read by all members of all shift teams.
Individuals are then asked to sign to acknowledge that they have read the 1-point lesson.
OPL should contain the elements,
1. Workshop location (plant, floor, line #)
2. A simply description of the purpose of this OPL
3. Use photographs or diagrams to show before and after sections
4. Who prepared the document? Who approved the document?
Below are the critical points for successfully implement OPL,
* Treat only one piece of knowledge at a time. The TPM approach is about small incremental steps to continuous improvement.
* Use simple clear language. The objects can be clear learned in 5 -10mins.
* Illustrate the idea with pictures or drawings closing to the place which it is applying.
* Make the 1-point lesson available to everyone who need to work on that process.
* Recognise and reward those who share their knowledge.

Terms of lean manufacturing
green - no problems
baka-yoke – In the past, Japanese called the mistake-proofing as baka-yoke, it meant fool-proofing. Baka is meaning foolish, however, somebody felt the term is not respect to people and changed it to poka-yoke.
heijunka - A production scheduling/leveling tool, essentially to distribute kanban cards in an efficient manner.
jidoka - a Japanese word which translates as autonomation; a form of automation in which machinery automatically inspects each item after producing it, ceasing production and notifying humans if a defect is detected; Toyota expands the meaning of jidoka to include the responsibility of all workers to function similarly, i.e. to check every item produced and to make no more if a defect is detected, until the cause of the defect has been identified and corrected.
jishu kanri - self-management, or voluntary participation.
jutsu - to talk, or ‘the art of’ (i.e., 'leanjutsu: the art of lean production').
kaikaku - A rapid and radical change process, sometimes used as a precursor to kaizen activities.
kaizen - the philosophy of continual improvement, that every process can and should be continually evaluated and improved in terms of time required, resources used, resultant quality, and other aspects relevant to the process.
kanban - a card or sheet used to authorize production or movement of an item.
karoshi - death from overwork.
mizusumashi - the classic 'water spider', who performs a wide range of tasks which allow workers to perform 'value-added' tasks.
mokeru - the Japanese term for the industrial engineering, more properly translated as ‘profit-making I.E.’.
muda (waste) - activities and results to be eliminated; within manufacturing, categories of waste, according to Shigeo Shingo.
mura - inconsistency
muri - unreasonable
nagara - smooth production flow, ideally one piece at a time, characterized by synchronization [balancing] of production processes and maximum utilization of available time, including overlapping of operations where practical.
ninjutsu - the art of invisibility (applies to management)
poka-yoke - a means of providing a visual or other signal as to the location or condition of a part characteristic. Often referred to as 'error-proofing', poke-yoke is actually the first step in truly error-proofing a system (see baka-yoke).
5S - refers to the five words seiri, seiton, seison, seiketsu, shitsuke. These words are shorthand expressions for principles of maintaining an effective, efficient workplace
seiri - eliminating everything not required for the work being performed
seiton - efficient placement and arrangement of equipment and material
seison - tidiness and cleanliness
seiketsu - ongoing, standardized, continually improving seiri, seiton, seison
shitsuke - discipline with leadership
seiban - Seiban is the name of a Japanese management practice taken from the Japanese words "sei", which means manufacturing, and "ban", which means number. A Seiban number is assigned to all parts, materials, and purchase orders associated with a particular customer job, or with a project, or anything else. This enables a manufacturer to track everything related with a particular product, project, or customer. It also facilitates setting aside inventory for specific projects or priorities. That makes it great for project and build-to-order manufacturing.
sensei - one who provides information; a teacher, instructor, or rabbi.
shojinka - continually optimizing the number of workers in a work center to meet the type and volume of demand imposed on the work center; shojinka requires workers trained in multiple disciplines; work center layout, such as U-shaped or circular, that supports a variable number of workers performing the tasks in the layout; the capability to vary the manufacturing process as appropriate to fit the demand profile.
teian - a proposal, proposition, or suggestion. A teian system can be likened to a system which allows and encourages workers to actively propose process and product improvements.

Case study 1
The Mahindra group follows a policy of non-retrenchment. Once upon a time, at Mahindra & Mahindra, Kandivali, 1134 employed produced 75 engines per day. After they went lean, they progressed to a production of 128 engines a day with 770 people. The rest of the employees were transferred to their Nasik plant. Today the plant at Kandivali has around 7800 workers in the automotive sector. Although the issue of the human resource may be delicate. The problem can be easily overcome, if handled with care and sensitivity.
Despite the difficulties associated with the implementation of ‘lean’, several companies have implemented it successfully and moved ahead. Mahindra & Mahindra selected the route of operational excellence to fight their competition. Regarding their success with the lean mode of operation, Mr. Rajan Narayan, (M & M’s Vice -President) says that they have achieved an improvement in the work culture, productivity and revenue at Mahindra & Mahindra solely due to the lean way.
Mahindra & Mahindra are not the only ones who have opted for the ‘lean’ method. Bajaj Auto Ltd., Pune, Lucas – TVS Ltd., Chennai and LML Ltd., Kanpur and are few of the companies that seem to the trading to the ‘lean’ route successfully.

A3 Management
At recent moment, I always found the term of A3 management in lean. I have no idea what is that once I heard that term, so I was searching the related information for further study. Finally, I found something but it is not so special for me but only its "name".
3. Clear stream of thinking in problem solving, it stated everything we need to consider in problem solving by sequences. We would not missed anything when we are going to improve the target.
Offcause, you can use A4 if you can write so small and the others can see clear what you wrote. On the other hand, you also can make it in A0 so that the others can read it like a map and feel sick in front of it. Altough, it is nothing special but it is a good way we should follow, because it is one kind of lean concept apply in documentation.

In memory of my mother school
"Reasonably training is forging, unreasonably training is grinding." was heard in my military training period in Taiwan. For 15 years, I can not forget that and it encourages me everyday when I went to deep end. I send this to all my good friends and hope it can help them to face the different troubles.
In mechanical theory,
Forging, is meaning to use heat treatment and forging to harden the metal. It makes the iron tough and hard.
Grinding, is meaning to use mechanical machining to grind the sharp edge of the metal. It makes the iron sharp.
Only volition (tough and hard) is not enough, we need braveness (sharp)!

Right or Wrong?
It was a bustup between the counterjumper and customer! For a soft drink worth HK$5.0!
The story was that, as we know, there is a soft drink machine for the customer to fill the drink by themselves. After they paid in the counter, customer got a empty paper/plastic cup and they went to the machine to fill which they wanted. There was a customer there told the counterjumper she gave her a wrong paper cup (for softdrink A). She wanted a soft drink was using the plastic cup (for softdrink B). But the counterjumper mentioned that the customer called for soft drink A but the customer clearly mentioned again she wanted a soft drink B. The customer told the counterjumper may be she heard the calling wrongly. And then the counterjumper change a plastic cup to her but during the exchange of cup, the counterjumper made emphasis the customer was ordering softdrink A repeatly. I believed that the counerjumper talked to customer at least five times for this. And then the bustup was started, and they shouted loudly and there were at least five people stood in front of the door to watch what happened inside. At the same time, I got my paper cup and filled the softdrink with my sons, and left the scene! When my family was leaving there, the bustup was not stop yet, and the customer was calling to the shop owner for complain...
I felt it was very funny! HK$5 almost made the ladies to fight there.
I have some questions to myself,
No matter the customer made mistake for calling or not, she should respect the customer. Just exchange the cup for customer and said, "that's fine, I will change it for you!". Nothing will happen and the customer will satisfy the service perfectly, actually, the shop has no any lost for the incident. Why she repectly emphasis the customer made the mistake?
For the incident, although the handling way of the counterjumper was not good enough, but is that really need to complain to the owner of the shop? May be the counterjumper would lose her job for a cup of soft drink. Can she explain to the counterjumper the she has wrong way to handle the issue? What is the right way to service the customer?
Actually, what is the right way to face a mistake we made? I don't know, but if we think we never made any mistake, it was absolutly wrong. Sometimes, the absolutly correct is incorrect , do the right thing, not do the thing right!

7 wastes - motion

Memorization = 5S in your brain
0. First of all, I am not the expert of memorization but we can have more information from Wiki link as below, Information of Memory from Wiki
1. Can people memorized everything?
I think it is possible. Physically, the memory size in our brain is infinitely. We can have a special training to strengthen memorization. Nowaday, we always equiped a PDA, even a mobile phone with additional memory. We can record everything we want to memorize by text, voice or photo. Therefore, basically, everybody can memorize anything they want, but...is that necessary to do so? Is that necessary we need to memorize the color of our dressing twenty days before? (Assumed that is not a special day we had such as the first time we were having dinner with our girl/boy friend...) Agree? Shift to next question.
2. Why we only memorize something we want?
No more talk about the handheld equipment, only focus the memory in our brain. I believed that our memorization is a selective system but we do not realize its process. We need to keep a spare space in brain for new event or thinking. If our brain is full of rubblish data (same as the rubblish email), it is a serious waste for us. In lean concept, it would be an issue of over stock / inventory, one of the 7 wastes.
First, we only need to memorize something important to us, such as our name, because we need to use that everyday. From working memory through interactive to long term memory. Second, we always can memorize the event which had deep image to ourselves. A simple question, where is the place you first time kiss your girl/boy friend? I think you can remember that in your whole life. From affective system or sensory system to long term memory. Third, we always memorized something which is not always used but need to remember, such as the birthday of your father. Actually, we only need to use that data once a year. From short term memory to long term memory.
3. Is that important of memorization?
A long time before, out of our brain, no other storage memory. All the information and knowledge only can be stored in the memory of brain. At that moment, memorization is so important. How much memory of knowledge you had, it represented how much knowledge you learned. In modern day, the above concept is meaningless, because we have too many devices having the same function of memory storage in our brain.
Now, we said, "undertstanding is more important than memorization.", why we said that? At my point of view, understanding means you have already memorized the truth. For instant, we learn driving in the thoeries of controling steering wheel and gear, it is very hard to forget after we started to drive a car. After we successfully got the driving license, that's mean we have the understanding of driving, you can not forget how to drive because you already understood how to drive. On the other hand, it is very easy to forget something if we do not understand or no way to understand. Can you remember all the numbers in yellow page? How long you can remember those number? The number on yellow page can not be used, that is meaningless for you. You have no way to understand that, and hard to remember.
4. What is factor help for memorization?
Based on the theory of "undertstanding is more important than memorization.", the most important factors improving the memorization are intellect and recombination. Intellect can make the intangible info to be a concrete image. Recombination can help you to put all the concrete image in sequence. Only one part you can remember, you can educe the whole subject.
It was a very common game shown in TV programme. We gave you some items no related such as a ball, a man, a chicken and a car, let you make a story using all the items. I would say, "A MAN played basketBALL, and then drove his CAR back to home, after playing basketball, he felt very hungry and he ate a CHICKEN in dinner by himself.". This is one kind of sample help you to memorize.
5. Which is needed to memorize?
In simply say, happy people only remember happiness. If your brain full of mirthless stories, I don't believed that you can be a happy people. No matter what we are talking about, you only recall the joyless memory to cause a negative emotion. That's a very terrible habit, but I have some friends doing that everyday.
Therefore, I suggest you only needed to remember your knowledge, and your good time. Clear up some spare space in your mind for thinking. Wash away the unhappiness. Do some 5S job for your brain.
OK, my friend, be a happy people!!!

Innovation and creative
Here is a great short movie!
We always reject some creative ideas during kaizen program because we are not sure is that work or not, but if we do not try the new idea, how do we know if it works or not? Just like the video shown above, the child looked like has a mental problem because it was only filled black color in his drawings. Once we puzzled some of the ideas together, we found it worked great.
Please do not reject the ideas from the others in improvement activities again, please!

Motivation needs theory in lean
David McClelland pioneered workplace motivational thinking, developing achievement-based motivational theory and models, and promoted improvements in employee assessment methods, advocating competency-based assessments and tests, arguing them to be better than traditional IQ and personality-based tests. His ideas have since been widely adopted in many organisations, and relate closely to the theory of Frederick Herzberg.
David McClelland is most noted for describing three types of motivational need, which he identified in his 1988 book, Human Motivation. He said that most people possess and exhibit a combination of these characteristics, bias to a particular motivational need, and this motivational or needs 'mix' consequently affects their behaviour and working/managing style.
David C McClelland's motivational needs theory,
Achievement motivation (n-ach)
David McClelland's needs-based motivational model These needs are found to varying degrees in all workers and managers, and this mix of motivational needs characterises a person's or manager's style and behaviour, both in terms of being motivated, and in the management and motivation others.
The need for achievement (n-ach) The n-ach person is 'achievement motivated' and therefore seeks achievement, attainment of realistic but challenging goals, and advancement in the job. There is a strong need for feedback as to achievement and progress, and a need for a sense of accomplishment. McClelland contrasted achievement-motivated people with gamblers, and dispelled a common pre-conception that n-ach 'achievement-motivated' people are big risk takers. On the contrary - typically, achievement-motivated individuals set goals which they can influence with their effort and ability, and as such the goal is considered to be achievable. This determined results-driven approach is almost invariably present in the character make-up of all successful business people and entrepreneurs. For the lean leaders with strong 'achievement motivation', they make the best leaders, but there can be a tendency to demand too much of their staff in the belief that they are all similarly and highly achievement-focused and results driven, which of course most people are not. On the other hand, they would like to use imperatively or compulsorily to lead the projects. Sometimes, they would even jump to the solution during the kaizen without any brain-storming discussion. Meditating myself, at the beginning stage of my leading of lean transformation, I made the same mistake as well.
The need for authority and power (n-pow) The n-pow person is 'authority motivated'. This driver produces a need to be influential, effective and to make an impact. There is a strong need to lead and for their ideas to prevail. There is also motivation and need towards increasing personal status and prestige. A strong n-pow 'authority-motivation' will produce a determined work ethic and commitment to the organisation, and while n-pow people are attracted to the leadership role, they may not possess the required flexibility and people-centred skills. Power motivation divided by two concept, individualistic power motivation and social power motivation. Because of the lean leader in individualistic power motivation tends to control the members in the team, the aggressive and trust in kaizen team was always be destroyed. Empowering members by the lean leaders with social power motivation can encourage and draw out the interesting of improvment.
The need for affiliation (n-affil) The n-affil person is 'affiliation motivated', and has a need for friendly relationships and is motivated towards interaction with other people. The affiliation driver produces motivation and need to be liked and held in popular regard. These people are team players. Mcclelland suggested that a strong n-affil 'affiliation-motivation' undermines a manager's objectivity, because of their need to be liked, and that this affects a manager's decision-making capability. At the same way, leading the lean transformation, we are no way to escape to challenge or be challenged. High affiliation leader would frustrate by this needs which can not be satisfied. Furthermore, because of they want to be liked by members, they cower to give their reasonable requests and challenge the team. Too high of this needs will cause the halt or slow down of lean transformation.
Not only talking about the lean leaders, basically, human being is full of these needs. The most important factor of success in lean transformation is well balancing the needs of motivation. Nobody can tell you what is the correct mix of needs, and you must build up a right mix according to the situation in different period of lean journey.

Albert's Gemba walk
For many years, I stayed in China for working and ignored the political news in Hong Kong. At recent moment, I left the current job and stayed Hong Kong, so I heard many news and started to care about my home town. I knew it is not good for me as a Hong Kong people, anyway, I am going to fix my mistake from now on.
Here is two video clips about Councillor Albert Chan (陳偉業) presented in legislative council, to resolve the Public Revenue Protection Order 2009, published in the Gazette as Legal Notice No. 27 of 2009 and laid on the table of the Legislative Council on 4 March 2009. In simply said, Hon Albert Chan proposed to cancel the increasing of tobacco tax. They were a excellent presentation for Albert's ideas, and he made me to think in different point of view for a matter.
My blog is always talking about the lean manufacturing concept. This time, I used the Albert's presentation to show my idea for lean as well. I am not going to agree or disagree with Albert's proposal, but it made me interesting on "vulgarity" news for the councillors. The clips were found in youtube.com and they made me understand why they did that in council. The first thing I most disappointed that the public media were all focusing on the vulgarity they said in council meeting, but why they did that? It was obviously that the media was going to mislead the story. Whatever, it is a political game and I am not going to present my point of view here.
The most interesting fact is Albert gave us many points which are based on the Hong Kong people's livelihood. He gave the analysis of the economic problem of the cigarette seller on the streets with real data supporting. I believed that Albert has visited the seller and got the real information on the street, he found that it has a deep impact of the income for the newpaper seller on the street. What is the meaning of Gemba walk? It is not only used in factory, the councillors supposed to has the gemba walk on the street to understand what is happening on there.
This is a fatal absurdity to elminate the red wine tax and double the tobacco tax. Is that the people drinking the red wine really live longer than the others? In the situation of economic down, the most important thing is to solve the problem on livelihood, it is nonsense to double the tax of tobacco and think it can solve the problem of smoking for thousands years. At recent moment, many and many problem on the medicines and its dealer, it was the problem of monitoring fron the government. A moment before, one hospital let a diver to die in front of her gate. What did the Secretary for Food and Health do? The best policy or solution never came from the nice and beautiful office, it must come from the Gemba!
I just hope the secretaries of department walk out from their office and see what is happening in Hong Kong, and learn some lean concept if possible.
