The Need for Innovation
Lev & Gu Model
Economic Performance =
(Physical Assets) +
(Financial Assets) +
(Intangible Assets)
Drivers of Stock Performance
Shareholder return is most closely correlated with growth in earnings from intangible
assets. Developing intangible assets requires competency in innovation.

Basic Concepts of TRIZ
TRIZ (pronounced as trees)
Russian acronym forTheory of Inventive Problem Solving
Originated in 1946 by Genrich Altshuller
from the study of patents.
Key Insights:
People invent better with abstracted
principles than with guesswork Studies of inventions can identify a
comprehensiveset of principles to use

What is an Inventive Problem?
No known means for solution
High psychological inertia
Different levels of solution Contains one or more contradictions
A contradictionis a situation where an attempt
to improve one feature of the system leads to
the degradation of another feature.

Define the Challenge and Problem
The initial statement may not really define the problem
Review the background of the problem
Collect available data
Redefine the problem
Wrong problem = wrong solution
Define what should be improved
What is the gap between where you are now andwhere you want to be?
What obstacles prevent easy movement to close
the gap?

Primary Function of a Paper Clip= Hold Two Pieces of Paper Together
Ideal System =Papers held together without the Paper Clip existing
Sum ofUseful Functions
Sum ofHarmful Functions
Ideal System
Ideal System - the function gets performed without the system existing

Acid

Chamber Destruction Problem
1. Exclude container from
the system
2. Now, find another way
to keep the acid in
contact with the
specimen
Imagine an Ideal System- the function is performed
without the existence the system.

Define Objectives
What the final result will look like?
What measurements will be used to define
success?
What is the minimum acceptable level of
performance?

Formulate Opportunities
Three Opportunities to improve Ideality:
1. Improve useful functions
2. Counteract harmful functions
3. Resolve the contradictions:
Contradictory Functionshould produce a
Useful result, and should not produce a
Harmful result.

Two sisters were fighting over the last orange.
The mother steps in to settle the argument.
How does she resolve the conflict?
Dividing the Orange
8/13/2019 TRIZ History
22/23
She cuts the orange in two, and gives each sister half.
A good compromise, but, is there a better solution?
Dividing the Orange
8/13/2019 TRIZ History
23/23
YES! Resolve the conflict.
Explore the needs of each.
One sister ate the orange and threw away the peel.
The other sister used the peel in a recipe, and threwaway the orange!
Clearly there is a solution which would delight bothparties!
