TRIZ (pronounced TREES) is the Russian acronym for the Theory of Inventive Problem Solving. This algorithmic approach to solving technical problems began in 1946 when the Russian engineer and scientist Genrikh Altshuller studied thousands of patents and noticed certain patterns. From these patterns he discovered that the evolution of a technical system is not a random process, but is governed by certain objective laws. These laws can be used to consciously develop a system along its path of technical evolution - by determining and implementing innovations.
Southbeach and TRIZ
TRIZ practitioners have developed conventions for the visual modelling of technical problems in products, services, business and society. Not all of these notations are consistent, even if they are individually valid.
Southbeach Notation was developed to embrace, unify and extend the different styles of diagram in common use. This was necessary so that a general purpose modelling tool and creativity engine could be developed.
