I came across an interesting approach to problem solving called
TRIZ this week. The development of
TRIZ began in 1946 with the mechanical engineer
Genrich Altshuller studying patents on behalf of the Russian navy.
Altshuller's job was to inspect invention proposals, help document them, and help others to invent. By 1969 he had reviewed about 40,000 patent abstracts in order to find out in what way the innovation had taken place. By examining a large database of inventions,
Altshuller concluded that only one per cent of inventions were genuinely original; the rest represented the novel application of previous ideas.
Altshuller argued that "An invention is the removal of technical contradictions". Along these lines, he said that to develop a method for inventing, one must scan a large number of inventions, identify the contradictions underlying them, and formulate the principle used by the inventor for their removal. Over the next years, he developed "40 Principles of Invention".
The
TRIZ process presents an approach for the analysis of problems in a technological system. The fundamental view is that almost all "inventions" are reiterations of previous discoveries already made in the same or other fields, and that problems can be reduced to contradictions between two elements. The goal of
TRIZ analysis is to achieve a better solution than a mere trade-off between the two elements, and the belief is that the solution almost certainly already exists somewhere in the patent literature.
A problem is first defined in terms of the ideal solution. The problem is analysed into its basic, abstract constituents according to a list of 39 items (for example, the weight of a stationery object, the use of energy by a moving object, the ease of repair etc.), and
reframed as a contradiction between two of these constituents. Using a contradiction matrix based upon large-scale analysis of patents, a series of suggested abstract solutions (for example "move from straight lines to curved", or "make the object porous") is offered, helping the analyst find creative practical solutions.
This all sounds a bit technical, however, there are clearly opportunities here for those of us working on the people
agenda. So it must
surely be worth considering what
TRIZ could tell us about contradictions such as Flexibility v Control, Diversity v Stability etc?
