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?

Good Better Nearly Ideal

Primary Function of a Paper Clip= Hold Two Pieces of Paper Together

Ideal System =Papers held together without the Paper Clip existing



Ideal System

Ideal System - the function gets performed without the system existing

Acid

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.




21/23

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


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


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!
