We all live with misconceptions, some even die with those. One of the misconceptions I was living with till date was- TRIZ is only meant for product companies. I am sure there would be thousand others who wouldn't want to challenge the paradigm. This mental block of mine was humble challenged by Prof. Prakash R Apte in a two day workshop on TRIZ last week. Hosted by CII Institute of Quality at Pune, the session saw some 12 practitioners from various companies learning and sharing their perspectives on the subject of Systematic Creativity. These were from Philips Innovation Campus, Mahindra and Mahindra, Honeywell, Praj Industries, Tata Steel, Parle Products, PSG College of Technology and Wipro (yours sincerely). Prof. Apte, with over 31 years of working with TIFR, followed by now teaching at IIT Bombay, was apt as the guide. Here's a quick 101 on TRIZ and what got discussed, and also on how my myth got burst.
TRIZ is an Russian acronym for "Theory of Inventive Problem Solving" devised by Genrich Altshuller in 1946. After doing extensive study of over 40,000 inventive patents, Altshuller arrived at the axiom that- the evolution of all technical systems is governed by objective laws. There exists a standard pattern of evolution of technical systems and the problems that one encounters today have already been solved before. Inventions solve these objective flaws. He identified inventions to largely fall under these categories: Apparent Solutions (32%), Minor Improvements (45%); Major Improvements (18%); Radical Change (4%); and Discovery (1%).
One of the fundamental principles of TRIZ is Ideality, which is defined as total value (good effects) from the system divided by total cost (harm effects). The Ideal Final Result (IFR) thus achieved though consistent inventions, ultimately does away with the system itself w/o compromising on the outcome. TRIZ suggests one to start with defining the IFR and then the 1-step back from it, which should be the true objective of the creativity.
He defined Inventive Problem solving to the solving of such contradictions. He defines broadly two types of contradictions- Technical and Physical. The former are classical engineering 'trade-offs' where if something gets better, something else gets worse. He depicts 39 such features and put them in a Contradiction Matrix. Further he assesses 40 Inventive Principles that could be use to address such contradictions. These include- segmentation, taking out, merging, skipping, copying, homogeneity, and periodic action, among others. At first these principles appear to suite only physical objects, but with a little bit of practice, one could easily abstract these to solve any problem. That's what helped my burst my myth.
On the other hand, the Physical contradictions are situations where one object has contradictory, opposite requirements. One could adopt one or more of the six separation principles to address these contradictions. These separations are in time, space, micro level, macro level, condition or to convert these to technical parameters.
As you can see from here, TRIZ doesn't believe in Optimization, it believes in Elimination of the problem/ contradiction. Means, TRIZ intends to arrive at Breakthrough Thinking instead of Trade-offs. Hence the power.
Another important tool from TIZ is studying the Trends of Evolution of Technical System, aka S- Curve study. Altshuller established 8 patterns of technial system evolution (today extended to 35), which includes- increasing ideality, matching and mismatching of parts, decreasing human efforts, etc. The S-Curve study helps establish the evolution pattern and identification of the room for invention.
One of the other interesting tools from TRIZ was S-Field Analysis and Standard Solutions. Stemming from the fact that every system can be subdivided to the lowest level where it could be represented as an interaction b/w two substances and a field. The so called Substance- Field (S-Field) model is the most fundamental way of eliminating constraint, by leveraging above principles.
In summary:
TRIZ is logical as it works on addressing constraints, the root cause of a problem,
TRIZ is not limited to a technical or physical domain. Services industry equally stands to gain from it. Needs ability to abstract and practice,
TRIZ gives tools which are person agnostic and furthers one's ability to visualise problem/ object in a granular fashion, and
TRIZ needs a due share of attention and evangelism in the light of the work that has already gone into it and the potential it possesses.
I got hugely benefited from the techniques and now am on with taking up few experiments back home in the company. Adding Practice to Theory (of Inventive Problem Solving)!
