What is Psychological inertia (PI) ?

· Deals with resistance to change due to human programming

· Creates barriers to innovative brainstorming during problem solving.

· Resulted from what a person has learnt before in the form of rules & regulations – do’s & dont's, tv, books, person we interact with

· The knowledge or experience creates boundaries & restrictions in a person’s mind

What Is Creativity ?

From human motivation , By Robert E. Franken, he defines that “creativity is defined as the tendency to generate or recognize ideas, alternatives, or possibilities that may be useful in solving problems, communicating with others, and entertaining ourselves and others.”(California State University, Northbridge)

What is Trimming?

· Trimming is a method of eliminating Components from an Engineering System to reduce or eliminate the disadvantages of those trimmed Components · Trimming is used to increase the efficiency and reduce the cost of the Engineering System Example :

Cause and Effect Chain Analysis :

· A cause-and-effect analysis generates hypotheses about possible causes(reasons) and effects(results) of problems · A Cause & Effect Chain (CEC) analysis diagram is a structured way of expressing hypothesis about the causes of a problem or about why something is not happening as desired · It helps to focus attention on the process where a problem is occurring and to allow for constructive use of facts to narrow down on the actual causes · It cannot replace empirical testing of these hypotheses, it does not tell which is the root cause, but rather the possibilities Example :

TRIZ process flow :

2 Key Steps : A) Function Analysis • Helps to clearly identify the Engineering System . • In function analysis we have the Supersystem, System and Subsystem. • Subsystem – component within Engineering system. • Supersystem – component outside system boundaries. Not designed as a part of the System. • System – components interaction between subsystem. B) Cause and Effect Chain Analysis • Help to identify the fundamental root cause(s). • These fundamental root causes are essentially the root causes of Engineering System problem which need to be resolved. Function can be categorized into two types : a) Useful i. ...
