TRIZTRIZProjects frequently reach a point where theanalysis is completed and the team is at a point
where it is unclear where they need to go forresolution. This applies not only to projects butto problem solving, root cause analysis, or
even Six Sigma (upon completion of theanalysis phase). The project team must becreative in order to determine what to do next.
TRIZ minimizes the chance of unpredictableand unrepeatable results that are associatedwith brainstorming or brainwriting.

TRIZTRIZ
TRIZ is based on the idea that many of
the underlying root problems thatengineers face today contain elementsthat have already been solved
(approximately 90%), often in acompletely different industry, for a
totally unrelated situation, that uses anentirely different technology.

The most important recognition is thattechnical systems evolve
Which evolves towards theincrease in ideality
By overcoming Contradictions
Achieved primarily with theminimal introduction of
resources

T.R.I.Z. (Trez or trees)
Theoria Resheneyva Isobretatelskehuh ZadachTheory of Inventive Problem Solving
Developed after WWII (1946) by GenrichAtschuller (1926-1998), a Russian inventor andnaval officer. He was sent to the Siberian Gulag
camp by Stalin for thinking too much. He wasreleased from prison after Stalins death.
Based on a theory that there are universal
principles of inventive and creativity. TRIZ is structured method that can be used to
rapidly generate plausible concepts that solveproblems in technical and non-technical domains.

@QAI
Altschuller / T.R.I.Z. Started with 400,000 patients, today it
includes the study of more than 2.5 millionpatients.
Altschuller discovery:
Each innovative patient solves a technicalproblem, but across domains, there are commonsolutions. These solutions were boiled down to 40principles.
Inventive problems often carry with them inherentcontradictions. (e.g. stronger, but heavier)
Anyone can use this knowledge and methodologyto solve problems.
Resources are often idle during problem solving.

Why TRIZ ?
Simply stated, we need to createinnovative products and services to
remain competitive ! We need to significantly improve the
engineers ability to quickly solve difficult and
seemingly impossible engineering problemswhich often lead to next generationinnovative products.

Altschuller Contradiction Matrix The 40 Inventive Principles can be utilized to solve
problems but unfortunately, fixing one problem oftenresults in creating another problem.Examples:
Companies buy other companies to grow andstrengthen themselves. This often results in acompany disorganized and less stable.
Coffee should be hot for enjoyable drinking
but cool enough to prevent burning thedrinker.Bandwidth increases (Good) but requires more
power (bad)
Training increases competence (Good) butrequires employees to be away from their jobresponsibilities (bad).
These contradictions can be resolved by applying theContradiction Principles in a Contradiction Matrix.

Altschuller Contradiction Matrix
As you can see from the examples onthe previous slide there are twocategories of contradictions.
1. Technical contradictions are based onclassical engineering of trade-offs. The
desired state can not be obtain becausethere is a barrier in the system.
2. Physical contradictions (Inherent) are
situations in which one object or systemcontradicts the requirements of the other.

ContradictionsContradictions appear first as a gapbetween demands and supplies. They
are overcome by break-throughinventions. These inventions form the
micro-steps of evolution in technicalsystems. Since the solutions are notknown, creative problem solving is the
method utilized to overcomecontradictions.

Contradiction Matrix
Are a result of Altschullers patent research
The principles are technical characteristics Can be applied throughout the Six Sigma
DMADV process whenever conflicts or
contradictions arise.
It is a large table that link pairs of the
engineering principles (39 X 39 matrix).

Contradiction Matrix
The core process is to drive a physical
contradiction (using the matrix) and solveit with the Separation Principle. Once thephysical contradiction is determined thissolution technique is powerful enough toidentify break-through (innovative)
solutions.
