Promotion of scientific methods in Olympus ( 1 ) Providing 7 solutions for the purpose 2009 2012 ～ 7 Solutions Typical Use of Methods QFD QFD Fuzzy Frontend Setting Theme Using various types Fast Cause Analysis of methods TRIZ Cost Reduction according to the problem Making Strong Patent Experiment ,Evaluation TRIZ TM TM Risk Prevention 4 2015/8/19 No data copy / No data transfer permitted 4 2015/8/19 No data copy / No data transfer permitted

5 2. Promotion of scientific methods in Olympus ( 2 ) Engineers are the customer for us. We‘ve been listening to the voice of the customer without force of methods. ◆ Anyway we are busy. Please shorten training time ・ Long time of training can not be accepted. Please set the training in the gap of work and work. ◆ Tell me how to resolve the problem not the methods. ・ Tell me what method are available in the scene. Purpose is not the use of method. We want to raise the efficiency in problem-solving. ◆ Stop the hard sell of QFD,TRIZ,and TM ・ I have failed at work by using the QFD. So, I do not like to use the scientific method. . (Allergy of scientific methods) ◆ It is difficult to resolve problems by one method. Why do you teach only one method ? ・ 1 method can not solve the problem. Please tell me the connection way of methods.

6 3. Seven Solutions meet the wide range of issues “ Functional Drawer ” is the Key of connecting 7 solutions Process is connected by the function wherever I open the drawer.

Function is the point of contact with TRIZ Good point of TRIZ is to generalize the complex problem TRIZ problem solving process Function Contradiction matrix Ｖ Ｏ Ｓ Technology General solution contradiction (Principle) Creation of ideas Generalization Functional element S Solutions acts V to the object O Problems in the field in the field The contact point between the methods and solutions

5. Connecting QFD by the function ( 1 ) 8 Connecting the needs and seeds by the function Seeds Customer Needs are the level of functions and Needs Technique is a means for requests for the function system does not realizing the functions have I want to boil the water in 1 minute Means of heating Heater ,Induction heating The specifications are the achievement level of the function Needs Seeds Driven Driven Means of keeping temperature Seeds Wool insulation ,Vacuum insulation Function Ｏ Ｓ Driven V Heater heats the bottom plate Ｓ Ｏ Needs V Ｓ V Ｏ Pot boils the water Driven Insulation keeps the temperature of the built-in case Function connects the seeds and needs !
