1. Picturization of accuracy & precision
Accurate and Precision
Accuracy & precision of a process
can be best explained by using the
analogy of a rifle firing at a target.

2. Accuracy and precision
With the center of the target taken to be the true
value of the characteristic being measured and
by the rifle shots representing the measured
values, there are four combinations of accuracy
and precision as depicted in the following slides.

3. Inaccurate and imprecise

4. Accurate and imprecise

5. Precise but inaccurate

6. Accurate and precise

7. Objectives of Six Sigma
As observed from the Picturization in the preceding slides, the objective of
moving towards world class manufacturing a is to continuously achieve
greater consistency of the processes by aiming for higher levels of accuracy
& precision
