3. Time requirement for the application of methods（１）5Designers are sensitive to the timeBecause..
◆No time for training after the Lehman Shock◆No time for new methods ,because productdevelopment cycle is fast
◆Not useful for methods such as QFD despite
the time-consumingLong time to apply methods and training is NG !

6. Summary

21① The product designers do not have time to put
new ideas and methods in their process.
So it is effective for us to promote and educatescientific methods based on 90 minutes.
② Promotion committee system has good function
for training of practitioners as follows.
・Division leaders are familiar with their technology
and problems for real-time support.
・ Division leaders discuss their technical andpromotional issues in the committee.
