4. Solution to the problem by scientific methods ( 2 )7

Customizing the method based on the voice of engineers
Step1．Solution by the process of “QFD → TRIZ → TM”・”QFD→TRIZ→TM” process does not always match to the start of the theme
・Believer of the method says that this method can solve all of the problems.
But, we can not solve them by one method.
・We want to check the effect by the first trial of method.

Step2．Customizing QFD,TRIZ and TM by the purpose
・Engineers would like to know what is valid method in each scene of development.
・My purpose is increasing the development efficiency ,not using the method.
Please show me the solution and effect to the problem.
・Managers and engineers have the experience of failure by QFD, TRIZ and TM
in the past, have a allergy to the method.
・Why is the only solution QFD, TRIZ and TM ? I think to use plenty of other methods.

Visualizing the development process byfunctional chain. And providing Solutions tothe target of problem by various methods.

Cause Analysis is more efficient than looking
for the cause in the functional model.

◆ Cause and Function Analysis leads to the root cause

However, oral simplistic “ Why ? Why ? "can not lead to the true root causes.

Summary① Visualization based on the functional Approach is effective
for using the scientific methods including TRIZ in the technicalproblem-solving process .
②Providing the Solutions are acceptable for developers naturally
without pushing to use scientific methods.

Next challenge
Our next challenge is to develop human resources who can provide
a cross-method solution.
