VAD R SIX SIGMA? 4
6.
The Goal
is to reach 6 Sigma in all products
and processes as well in the
Product Development flow as in the Customer Supply flow.
Short term it is to give savings
and fulfill the goals of the organization.

The Strategy is to use Powerful Statistical tools like:
Factorial Experiments (DOE)
Regression Analysis
Hypothesis Testing
SPC and so on
STRATEGI 6
8. SIX SIGMA CRITICAL 3 FACTOR INTERACTION 7
Defining and using metrics that focus our attention on defects
that are most important to the customer and have the greatest
potential for impacting the bottom line.
Dedicated
resources trained in the use of the 6 Sigma problem solving
methodology.
Systematic Approach to reducing defects which affect what is
important to the customer (qualitative & statistical).

19. A pragmatic case study in color matching
Nya tuffare krav p kulr-matchning gentemot tidigare
modeller
Kraven specificeras fr kulrmtning enligt CIELAB-standard
Mtning sker p:
Glans
Ljushet (L)
Kulrton rtt-grnt (a)
Kulrton gult-bltt (b)
Fr att kunna faststlla en stabil process mste orsakerna till
akut variation elimineras och den kroniska variationen
studeras.

Matt, svart yta ger nstan ingen reflektion. En liten variation
fr en enskild frekvens i spektrat ger ett stort utslag p mtvrdena i
CIE-Lab.
Repeterbarhet och kalibrering sker alltid mot vit yta. Vr
utrustning har repeterbarhet p E=0,15 fr vit yta.
Minoltas bsta utrustning ger inte speciellt mycket bttre vrden
p matt, svart yta.
