O i t f thi t i i i t t i th• One main part of this training is structuring the process
improvement efforts.
• The key to process improvement is a successful
completion of the measure and analysis phase, which
b ild th f d ti f th i tbuilds the foundation for the improvement.
• However, if those in charge are very familiar with the
process they often contribute good ideas. These should
be examined independent from the stage or working
phase the project is inphase the project is in.
• These examinations are called „Rifle shot Studies“
(Juran).

2. Aspects of the "Rifle Shot Studies"
P• Purpose:
– "Rifle shot Studies" should concentrate on one or two
i t i bl th t hi hl l t d t th blinput variables that are highly related to the problem.
• Example: We are quite sure to know the new raw
t i l f b ttmaterial performs better.
• Example: Increasing the temperature about 10° in the
ti l i th i ldreaction vessel improves the yield.
• Methodology:
– Steps that lead to a proper experimental design shouldSteps t at ead to a p ope e pe e ta des g s ou d

• „Rifle Shot Studies“ executed at the beginning of a
project help the team to become a unit for two reasons:project help the team to become a unit for two reasons:
– The team‘s ideas are worth to follow
– Facts can make decisions very easy
