TRIZ in a Bi-system, Consisting of TRIZ and Lean Sigma

As any system, TRIZ behaves according to the trends of the General Systems’ Theory. According to one of the trends, technological systems evolve in a general direction from mono-systems to bi- or poly-systems. Then the bi- and poly-systems convolute into mono-systems. TRIZ is not an exception to this trend. To date, TRIZ and a modified Value Engineering (VE) function analysis comprise a mono-system of contemporary TRIZ.

At a close review, TRIZ provides qualitative assessment and analysis of the system under consideration. Yet, in a technical system analysis a numerical representation of system’s features, functionalities and problems is very important as it provides a universal assessment of system’s parameters and provides foundation for comparative analysis of the system and its environment.

Therefore, it is imperative that TRIZ is equipped with necessary tools for quantitative assessment of system’s parameters. In the last 8-10 years a number of attempts were made in combining TRIZ with some other methodologies. Most popular are attempts to combine TRIZ with Six Sigma. However, these attempts were made by Six Sigma experts, who are not very experienced with TRIZ and its tools. As a result, TRIZ is placed in a subordinate position to Six Sigma. Most notable is TRIZ application with DFSS – Design for Six Sigma, where some TRIZ tools are utilized for solution of design issues. A more detailed analysis of these attempts will be provided in the body of the paper.

Case Studies From A Breakthrough Innovation
"Starting in August 2004, the Hong Kong government began sponsoring a deployment of TRIZ to a cluster of eight local companies. Over the course of the next 15 months, each company was invited to assemble a team of between 5 and 8 engineers and designers each of whom would be exposed to a series of six three-day TRIZ education and utilization sessions. The aims of the program were for each company to realize new products, patents and tangible financial benefits, and to measure the extent to which TRIZ allowed companies to accelerate their rate of innovation. This paper describes a collection of some of the success stories emerging from the program."

Alexander Selyutsky - a key figure in the history of TRIZ!

Alexander Selyutsky

Selyutsky Alexander Borisovich was born April 6, 1933 to an intelligent Jewish family residing in Leningrad. During the World War II the plant where his father was working was evacuated to the Urals, and the family (the parents and Alexander) moved to Chelyabinsk. Here, Alexander graduated from high school. He wanted to go to a military school, but didn’t pass vision test and entered the Chelyabinsk Polytechnic Institute. In his first year he was forced to learn boxing (because of frequent anti-Semitic attacks) and became a Komsomol activist.

After graduation, he was sent to Petrozavodsk Onega tractor plant, where he worked as a designer. He continued leading a very active social life, organized and led voluntary militia patrolling the streets of the city because the situation was very criminal. In the search for more satisfying work he became interested in patenting, completed appropriate courses and became a patent agent.

In 1960, Alexander married Dolly Naumovna Audleys, and had a daughter Alla in 1961. The same year G.S Altshuller published a book " “Learn how to invent"[1] . After reading this book in 1965 Selyutsky wrote a letter to Altshuller. This letter started their acquaintance by correspondence. Since then, Alexander became one of the most dedicated Altshuller’s disciples and an active promoter of the emerging new science.

They finally met in 1968 in Dzintary (near Riga), at the seminar organized by the Central Board of VOIR (state leading inventors’ and innovators’ society) that invited Altshuller and several of his associates. It was the first time that Alexander and others got a chance to work under the direct guidance of Altshuller and to learn from him. Later, in 1983, Alexander participated as one of the instructors in the seminar conducted by G.S. Altshuller in Moscow at the Institute for continuous education for chemical and petroleum industries.
