To test whether the sample mean is equal to the population mean (variance is known) -
ANS-One Sample Z-Test
When counting "number of defects" in fixed sample size each time - ANS-C-Chart
When measuring "number of defects per unit" in variable sample sizes - ANS-U-Chart
When measuring "number of defectives" in each sample (fixed sample sizes) - ANS-nP-Chart
When measuring "percent of defectives" in each sample (variable sample size) - ANS-P-Chart
When measuring a continuous variable using samples of fixed size - ANS-X-Bar (r or s)
Helps to show complexity that may be simplified, redundancies that may be eliminated, and
procedures that may be standardized. - ANS-Simple Process Flow Chart
Shows transportation and work flow. - ANS-Spaghetti Diagram
Shows employee and machine relationships - ANS-Worker Machine Chart
Material and information flow at high level for product families consuming common sets of
resources; typically at the plant/facility level. - ANS-Value Stream Maps
Purpose: organize facts, opinions, and issues into natural groups; use to find themes and
messages in customer statements (interviews, surveys, focus groups) - ANS-Affinity Diagram
