-- Editorial:　Southbeach Forum on Southbeach Notation and Modelling: A Forum for Introduction, Communication, and Evaluation (Toru Nakagawa) (Jun. 9, 2013)

A discussion forum on Southbeach Modelling, including its visual language , software tool (Southbeach Modeller), modelling methods , and their applications. This page will post introductory information from the developer and various communications and reports from users, including myself.

--　Editorial:　Southbeach Trial & Evaluation Project in Japan: "CrePS-SB Project" (Toru Nakagawa) (Jun. 9, 2013)

For the purpose of encouraging the trial use and evaluation of the Southbeach Modelling, I started the "CrePS-SB Project" in Japan. For reducing the cost barrier for the trial of making models with the software tool, I have arranged to offer free '3-month Editor mode license' to a group of volunteers.

-- Forum:　Easy Use of Southbeach Modeller (Toru Nakagawa) (Jun. 9, 2013)

When I translated Howard Smith's White paper into Japanese, I myself drew the 27 diagrams in Japanese with the use of Modeller while looking at the printed English versionｓ. The drawing work was done in less than a day, thanks to the software tool in its easiness to learn and convenience to use. I have posted a note on how to use the Modeller for beginners .

-- TRIZ Paper:　Red, Green, and Blue - Situational Improvement Using Southbeach (Howard Smith (CSC European Group, UK); Japanese translation: Toru Nakagawa (OGU)), (Jun. 9, 2013)

The present paper describes the basic language implemented in the Southbeach Modeller and also the philosophy and application of the modelling method. For representing 'Situations', the author uses diagrams with boxes and arrows. Boxes represent things and facts while arrows the relationships between the boxes. Red shows something harmful (such as problems), while green something useful (such as solutions). Diagrams can be made in various perspectives and then analyzed.
The modelling method allows to represent different and conflicting views and opinions with the diagrams and to guide the group of different people toward alignment for improving the situation. The author explains such a process convincingly (or 'logically') by using a number of examples. He talks about contradictions and problem solving in common cases in the business field. I feel his explanations fresh and insightful, and are easy and convincing for people in non-technological fields. The present modelling method/tool can be used universally with a large range of methods and techniques for problem solving and group decision making.

-- TRIZ Software Tool: Overview of Southbeach Modeller 3.0: A General Purpose Software for Building Thinking Models (Southbeach Solutions Ltd., UK) (Introduction and Japanese translation: Toru Nakagawa) (May 29, 2013)

Here is a software tool developed recently in UK, under the influence of TRIZ tool for Cause-Effect diagrams and being extended much further for building various types of thinking models in an easy and generalized manner. The developers had the motive of improving the ways of business process innovation by introducing modern TRIZ. They made a basic plan around 2006, established their model description language 'Southbeach Notation' in 2008, and have been implementing it into a software tool. In 2011, Howard Smith published a paper describing the possibilities of how such an easy modelling tool can support idea generation and communication in human and technology problems. They have just released the Modeller 3.0 and published its Overview. Their Web site discloses a rich library of documents including many application examples. I suppose that the present tool is rich in descriptive power, general purpose usage, functionality, and also handy and inexpensive. I am impressed with their idea of "Just like Spread Sheets for numbers, Modelling Sheets for ideas". Under the permission by SB, I have translated their Overview slides into Japanese and am posting them in HTML and in PDF .

-- Promotion Case Study:　Establishing TRIZ in a global company (Pauline Marsh (BAE Systems, UK), Karen Gadd (Oxford Creativity, UK)) (Japanese translation: Toru Nakagawa)　 (May 29, 2013)

Presented at ETRIA TFC 2012 last October in Lisbon, Portugal. This is the first and detailed report of the 14 year experiences of establishing TRIZ in a global company, BAE Systems, in UK. TRIZ has been introduced and promoted steadily since 1998 and are used company-widely. Selecting proper methods (including TRIZ) and proper instructors, incorporating the courses in the already established HR programs, promoters within BAE made TRIZ available to any individuals and teams as they needed. The consultants at Oxford Creativity operated workshops for practical problem solving; they are regular 5-day courses designed to be taken as five 1-day courses as well. In the workshops, they first gather initial ideas from everybody by a brainstorming, openly discuss good and bad points of the ideas, and set them all aside with the labeling of 'BAD solutions' for the purpose of exploring for BEST solutions with TRIZ. The authors repeatedly write that 'Individual TRIZ tools are simple and straightforward, and they stimulate your thinking'. The present paper is full of lessons based on their experiences. English paper in PDF , and Japanese translation in HTML . (English slides are to be posted here in July.)

-- Introductory: TRIZ Application 5: Application of TRIZ to Risk Management for Avoiding Unexpected Dangers (Teruyuki Kamimura (Ideation Japan)) (May 19, 2013)

The last article in the TRIZ Special Issue of the JSA's monthly journal "Standardization and QC" 　. After the March 11 Japan Disaster, we have realized the importance of risk management. We had big weak points not only in our attitudes but also in the conventional methods of risk foreseeing and management. Since many years ago TRIZ has developed the subversion analysis method for foreseeing risks, where failures of a system are found to occur by trying to 'invent' the ways of causing failures. Anticipatory Failure Determination (AFD) developed at Ideation International is described well in this article. HTML and PDF in Japanese.

-- Introductory: TRIZ Application 4: Strategic Application of TRIZ for Constructing Intellectual Properties for Winning in Business (Kimihiko Hasegawa (Ideation Japan)) (May 19, 2013)

The 7th article in the TRIZ Special Issue of the JSA's monthly journal　"Standardization and QC" 　. This article describes the strategic importance of constructing IP properly. It describes how one can think of the circumventing other's patents, and then how one should build patents which cannot be walked around. HTML and PDF in Japanese.

-- Introductory: TRIZ Application 3: Integral Use of TRIZ and VE for Creating New Values -- Development of Comfortable Toilet Spaces in Railway Cars (Keiji Inoue (East Japan Railway)) (May 19, 2013)

The 6th article in the TRIZ Special Issue of the JSA's monthly journal　"Standardization and QC"　. This work was originally presented in Nov. 2003 at Japan VE Association Conference, and its slides were posted in this site on Jan. 28, 2004 . The author's group were engaged in developing a new design of toilet spaces in Shinkansen. Their design has already been realized in new cars of Bullet trains of JR East (covering Tokyo and northern part of Honshu). I actually got on such a train a year ago and was amazed with its nice design of the toilet space, much different from the typical ones in the Bullet trains running between Tokyo and Osaka. The author's group was using VE for a long time and introduced TRIZ newly for the purpose of foreseeing the future. The paper describes their integral use of VE and TRIZ; an excellent case study report on both the process and the resultant information. HTML and PDF in Japanese.

-- Editorial: Collaboration Pages with the Promoters of TRIZ and Related Areas: Aims and Call for Contributions (T. Nakagawa) (May 10, 2013)

Three years ago we started 'Collabo Pages' in Japanese . Since they may be productive also under international cooperation, I am now posting the descriptions of the aims of the pages and call for your contributions. Collabo pages accept contributions of (relatively brief) introductions/communications by different TRIZ promoters in Japan and in the world more-or-less regularly. This may be a new way of cooperation for proliferating TRIZ, much stronger than simple mutual links. [This page was prepared for posting on Dec. 24, 2010, but missed. Recognizing this mistake now, I am posting it here as a part of 'To-Do-List for TRIZ'.]

-- Editorial: To-Do-List for TRIZ (T. Nakagawa) (May 8; May 10, 2013)

A list of items which we should better do (with this Web site) for understanding and penetrating TRIZ is revised after 4 years of interval (in Japanese). (a) Revision of the list of TRIZ references and the list of TRIZ links (in Japan and in the world), (b) Introductory pages (or sub-sites) friendly to TRIZ novices, younger people, and children, (c) Collaborative pages with various TRIZ promoters, (d) Japanese translation of important overseas papers/articles, (e) English translation of important Japanese papers/articles, etc. Publication of books and training activities are also important for me to do. I wish the readers to cooperate with me in these activities. [The page is posted also in English . (May 10, 2013)]

-- TRIZ News: Nakagawa's Activities (Reports and Plans) (May 8, 2013)

Nakagawa's activities (especially conferences, seminars, trainings, etc.) are briefly described in Japanese. I conducted a 2-day TRIZ/USIT training seminar for SME engineers last February at Hokuriku Polytechnic College. Lectures on the first-day morning, USIT practice on 3 problems in parallel in the afternoon, and on the second day USIT practice again on 3 different problems.

-- Introductory article: TRIZ Application 2: Easy Practice of Applying TRIZ -- Concepts and Application of USIT (Unified Structured Inventive Thinking) (Toru Nakagawa) (May 8, 2013)

This is the 5th paper in the Special Issue of "Standardization and Quality Control". Since TRIZ has very rich contents of knowledge and techniques, different ways of practices and application have been proposed. Among them, I have been recommending USIT as a compact and well-designed process, easy to understand and to apply. USIT was originally developed by Ed Sickafus, and was further extended in Japan. I explain USIT on the basis of my current understanding of it as the new paradigm of creative problem solving. Two case studies demonstrate the USIT process; one is the improvement of a filter for separating plasma from blood, while the other is developing a new type of 'Mom's bicycle for safely carrying two children'. You can see the concepts and ways of thinking in USIT in this concise 6 page article, I hope. 　Japanese pages , and English translation page .

-- Introductory article: TRIZ Application 1: Innovative Solution to Technological Problems by Effective Use of TRIZ (Setsuo Arita (Hitachi), Kazushi Tsuwako (HGST)) (May 8, 2013)

The 4th article in the TRIZ Special Issue of the JSA's monthly journal. Hitachi Group companies have been most active and successful in Japan to apply TRIZ in their real projects, of over 4500 cases since 1997. An application case is demonstrated here; for recovering the damage on the coded surface of a hard disk they got a TRIZ solution of smashing out the extrusion with the HDD head itself. Another case presented by Dr. Hong-Wook Lee (Hundai-Kia Motors, Korea) at Japan TRIZ Symposium 2010 is also introduced here for illustrating a process of circumventing others' patents on variable-ratio engines and developing an new scheme step by step. HTML and PDF in Japanese.

-- USIT Lectures: USIT News Letters and Mini Lectures (No. 19 to No. 28) (Ed Sickafus; Japanese translation Toru Nakagawa) (Apr. 6, 2013)

Dr. Ed Sickafus is the original developer of USIT, and he published USIT News Letters in 79 issues from Nov. 2003 to Mar. 2009 for sharing his thoughts. 10 issues of them are now posted in Japanese translation and also in English PDF. The Mini Lectures in the News Letters are excellent introduction not only to USIT but also to problem solving methodologies in general, being full of deep insights and dynamic way of thinking.

-- TRIZ Promotion: Malaysia TRIZ and Its Strategies (TS Yeoh, MyTRIZ Malaysia) (Annotation and Japanese translation: T. Nakagawa) (Apr. 6, 2013)

In the Keynote Speech at MyTRIZ Conference 2012 last November, Dr. TS Yeoh talked about their strategies of proliferating TRIZ in Malaysia. MyTRIZ (Malaysia TRIZ Innovation Association) was formed in 2010 and then the crutial foundation of the movement was built in the form of MOU signed by the three parties: Ministry of Higher Education (governing universities), Multimedia Development Corporation (promoting ICT as a government agency), and Intel Malaysia (well experienced in TRIZ). They agreed to cooperate in proliferating TRIZ among the nation, and to set their initial target to train university lecturers. Universities set up the training opportunities and Intel sends its TRIZ experts as trainers without charge. They have trained 1057 lecturers already as the MATRIZ Level 1 practitioners. His slide conclude with the statements: "Collaboration worked! Implementation progressing well. Ride momentum and stay focused." -- Original slides in PDF and brief annotation by Nakagawa in English. Japanese page contains slides in Japanese translation and full annotation by Nakagawa.

-- TRIZ papers: "Theory of Resolving Differences (2)", The Second Collection of Papers Written by Toshio Takahara (2008-2012) (Annotated Bibliography and 13 Papers) (Mar. 7, 2013)

This page is a collection of all the 13 papers/presentations published by Toshio Takahara from 2008 to 2012 in the area related to TRIZ. It contains an annotated bibliography written by the author and links to individual papers in PDF. His first collection (of papers 2003 - 2007) was posted in 2008. 'Differences' refer to those between the desired situation and the present situation, and hence 'Resolving Differences' implies both problem solving and task achievement.
A list of papers is shown below; links to the HTML pages posted earlier are shown, but links to PDF files are omitted. Takahara summarizes "From 2008 to 2012, I have worked on the topics of (1) Radical thinking for enumeration, (2) Basic concepts of movement and contradiction, and (3) Way of life. All these topics are interrelated." The author had a heart surgery a year ago and even while the process of recovery he wrote a few papers. We wish him health and happiness.

-- USIT Lectures: USIT News Letters and Mini Lectures (Ed Sickafus) (Japanese translation: Toru Nakagawa) (Jan. 30, 2013)

Dr. Ed Sickafus is the original developer of USIT (Unified Structured Inventive Thinking). Though he retired Ford Motor Company in 2000, he has been active in developing his theories further and in sharing his thoughts and experiences. He started his 'U-SIT and Think News Letter' since November 2003, sometimes weekly and some other times irregularly, and up to No. 79 in Mar. 2009. The column of 'Mini Lecture' describes his thoughts and applications of USIT to familiar problems; they are very interesting and enjoyable to read, containing insights. We posted the Japanese translation versions from No. 1 to No. 10 in 2004. After 9 years of interruption, I restarted to posting the Japanese edition step by step. Dr. Sickafus has kindly permitted me to post his original English Editions in PDF in this Web site.

-- From the Editor: General Index of this site has been revised (Toru Nakagawa) (Jan. 9, 2013)

The present site has a powerful feature that all the articles accumulated for over 14 years are kept active with easy access. The General Index page is the key tool for the purpose. All the articles are classified into their categories and arranged in the chronological order (the latest at the top) in each (sub)category, and are accessible by one click to the individual pages. In the revision this time, the overall structure is kept as before without change but the categorization is slightly revised and is shown more clearly with the color coding of the table and in a consistent formatting. There are a number of articles which are added from missing, enhanced in the reference, moved to more appropriate subcategories, etc. The index is quite large, of 37 printed pages in English and of 30 in Japanese, and yet useful and handy for accessing articles you want.
[For example, see some old articles, such as 'Report of A Personal Trip to TRIZ Mother Countries (Russia & Belarus, Aug. 1999)' (TN, Aug. 23, 1999), 'Experiences with My Teacher G. S. Altshuller' (Phan Dung, May 8, 2001), and 'Tech Optimizer 2.5 -- Mechanism, usage and methodology learning (TN, Feb. 25, 1999). These articles are posted both in English and in Japanese.]

-- From the Editor: Message for the New Year 2013 (Toru Nakagawa) (Jan. 9, 2013)

Greetings from Japan for a Happy New Year 2013! I have resigned by the end of last December from the Board and Management Members of the Japan TRIZ Society, NPO. But I still have a strong will to "develop TRIZ/USIT further and make it useful for solving problems and achieving tasks in many and different issues in Japan and in the World", and continue to be active as the Editor of the "TRIZ Home Page in Japan" as before. I wish to make this home page a 'Public site' really useful for learners and practitioners of TRIZ/USIT in collaboration with many authors and readers in Japan and in the World.

-- TRIZ / USIT Documents: TRIZ and USIT Solution Generation Methods -- Cross References (Toru Nakagawa) (Posted: Apr. 3, 2003; Withdrawn: Apr. 8, 2003 - Dec. 21, 2012; Posted: Dec. 22, 2012)

The present page and a set of its subsequent pages represent the cross references between the solution generation methods in TRIZ (including 40 Inventive Principles, 76 Inventive Standards, and Trends of System Evolution) and those in USIT (Sickfus' 21 Heuristics, and the USIT Operators we developed). Correspondences from individual TRIZ methods to USIT sub-operators and also from individual USIT sub-operators to TRIZ methods can be read in these pages. They are useful as the cross references in the both directions TRIZ <---> USIT. These documents were originally developed during our work for reorganizing the whole TRIZ solution generation methods into the USIT Operators, as presented in ETRIA TFC 2002 in Nov. 2002 .
Among them, the TRIZ --> USIT reference pages (i.e., the (0) - (4) pages shown bellow) were once posted on Apr. 3, 2003, but were withdrawn on Apr. 8, 2003 because of my mishandling of the copyrights of TRIZ references. After over 9 years, I am re-uploading them today with a revision of reference descriptions under the permissions by the relevant authors. I would like to express my sincere apologies for my mishandling and also my thanks for giving me permissions of posting to the relevant authors: Ms. Larisa & Yuna Komarcheva (the copyright owners of Mr. Genrich Altshuller's works), Dr. Yuri Salamatov, Mr. Darrell Mann, and Dr. Ed. Sickafus.

-- TRIZ Forum: How to Nurture and Develop Innovative Talent? (Toru Nakagawa) (Dec. 12, 2012)

Presented at Panel Discussion of Malaysia MyTRIZ Con 2012 on Nov. 8, 2012. Slides and description of the talk, on 3 questions. (Q1) How to nurture and develop creative (innovative) talent? --> 'Creative power' = 'Creativity' × 'Continuing efforts'. And 'creativity' may contain some types of attitudes, minds, capabilities, ways of thinking, etc. Different types of creativity urge different ways of nurturing. (Q2) When and how did you get interested in innovation science? --> I happened to encounter TRIZ in 1997 at a seminar. There were backgrounds for me to get interested in it. ... (Q3) Do you think school education limits the growth of students' creativity? --> It depends. Teaching a student to be creative or not is just the accumulation of positive and negative responses by the teacher (and parents and others) in various occasions of student's action and thinking for many years. ... The page is a record of my thoughts on these delicate questions.

-- TRIZ/USIT Paper: Creative Problem-Solving MethodologiesTRIZ/USIT: Overview of My 15 Years in Research, Education, and Promotion (Toru Nakagawa) (Dec. 12, 2012)

Keynote Lecture presented at Malaysia MyTRIZ Con 2012, on Nov. 8, 2012 at Penang, Malaysia. This is based on my paper and my talk presented last March just before my retirement from OGU. I am talking how I have been studying and extending TRIZ in research for these 15 years since I encountered TRIZ in 1997. The main theme of my research has been extended: TRIZ --> USIT --> New paradigm of creative problem solving (Six-Box Scheme) --> General Methodology for Creative Problem Solving. The fourth stage just started last May. "Easy to learn, applicable everywhere, and effective" is my motive in developing a creative problem-solving / task-achieving methodology. Slides are posted in HTML images and in PDF .

-- TRIZ Conference Report (26): Malaysia MyTRIZ Conference 2012 (Nov. 6 - 9, 2012 at Penang, Malaysia) Participation Report (Toru Nakagawa) (Nov. 15; Dec. 12, 2012)

A brief report, written for the management members of JTS on Nov. 12, is posted in the Japanese page with minor modification. A very impressive event consisting of Conference, Workshop, and Competition. Held by MyTRIZ (Malaysia TRIZ Innovation Association), with the support of 2 Government Ministries, MDeC (a national agency in the field of ICT), Intel Malaysia, Univ. Science Malaysia, etc. A strategic 3-party agreement was made in 2010 among Intel Malaysia, Malaysian government, and Malaysian universities: 'Training of TRIZ to university lecturers are promoted by university's setting up, Intel's providing with its TRIZ experts without charge, and government encouragement. Then the lecturers teach TRIZ to students.' On the basis of this strategy, the Competition was carried out with the entree of 27 teams from various universities. MyTRIZ has about 50 members from industry and about 200 from universities.
Conference had interesting invited talks both on industrial promotion/application and on teaching at universities and for children. 6 Keynote speakers were invited from abroad, and TRIZ pioneers in Malaysia gave very good presentations. Proceedings were not prepared beforehand. When the presentation slides are posted in their Web, I wish to introduce several of the presentations in this site as well.
