TrizDescription:
TRIZ is spreading into corporate use across several parallel paths – it is increasingly common in Six Sigma processes, in project management and risk management systems, and in organizational innovation initiatives. research began with the hypothesis that there are universal principles of creativity that are the basis for creative innovations that advance technology. If these principles could be identified and codified, they could be taught to people to make the process of creativity more predictable. The short version of this is:
Somebody someplace has already solved this problem (or one very similar to it.) Creativity is now finding that solution and adapting it to this particular problem. General guidelines: 1. Problems and solutions are repeated across industries and sciences. The classification of the contradictions in each problem predicts the creative solutions to that problem. 2. Patterns of technical evolution are repeated across industries and sciences. 3. Creative innovations use scientific effects outside the field where they were developed.
The TRIZ general problem at the highest level is to find a way to produce the product with no waste, at 100 percent yield, with no added complexity.
For example, consider using a laser instead of a scalpel for eye surgery. In this case, ultrasound can be used to break the cell walls or using an enzyme to "eat" the cell wall (chemical energy) instead of hitting them. This may seem very general, but it led the pharmaceutical researchers to analyze all the resources available in the problem (the cells, the cell walls, the fluid they are in, the motion of the fluid, the processing facility, etc.) and to conclude that three specific solutions had high potential for their problem: 1. The cell walls should be broken by sound waves (from the pattern of evolution of replacing mechanical means by fields). 2. The cell walls should be broken by shearing, as they pass through the processing facility (using the resources of the existing system in a different way). 3. An enzyme in the fluid should "eat" the cell walls and release the contents at the desired time. All three methods have been tested successfully. The least expensive, highest yield method was soon put in production.
The "General TRIZ Solutions" referred to in Exhibit 1 have been developed over the course of the 60 years of TRIZ research, and have been organized in many different ways. Some of these are analytic methods such as: • The Ideal Final Result and Ideality, • Functional Modeling, Analysis and Trimming and • Locating the Zones of Conflict. (This is more familiar to Six Sigma problem solvers as "Root Cause Analysis.")Some are more prescriptive such as: • The 40 Inventive Principles of Problem Solving, • The Separation Principles, • Laws of Technical Evolution and Technology Forecasting and • 76 Standard Solutions. In the course of solving any one technical problem, one tool or many can be used. The 40 Principles of Problem Solving are the most accessible "tool" of TRIZ. These are the principles that were found to repeat across many fields, as solutions to many general contradictions, which are at the heart of many problems.

Triz is a problem solving method based on logic and data, not intuition, which accelerates the project team's ability to solve these problems creatively.
A TRIZ general solution formula is "The problem should solve itself." One of the patterns of evolution of technology is that energy (fields) replaces objects (mechanical devices).
