Which statement(s) are incorrect about Fractional Factorial Designs?

Resolution V design is desired while controlling costs of experimentation

A Half Fractional Design for 5 factors has the same number of experimental runs as a Full Factorial Design for 4 factors assuming no repeats or replicates or Center Points

Quarter Fractional experiments can exist for those with 4 factors

Resolution V design is desired while controlling costs of experimentation

Half Fractional experiments do not exist for those designs with only 2 factors

Questions that can be best answered by a Visual Factory include all of these except _____________________.

Are setups optimized for lower scrap levels?

Can extra inventory be seen easily?

Can changeover challenges be recognized?

Are unneeded tools or supplies easily noted?

Situations where standardized work needs to be incorporated include all of these except _____________________.

Machines continually operating to reduce the labor cost per piece

Changeover instructions incomplete

Lack of a system to assure proper inventory levels at repair stations

Machines continually operating to reduce the labor cost per piece

Process flow for the same product assembly taking various cycle time for completion

If a Six Sigma project was to reduce changeover times and the team found the project success was decreasing over time since changeover times began to creep back up, which Lean tools should be considered in the Control Phase to reestablish and sustain the project success?

Confirm a Visual Factory exists to assure proper communication of status of machines

Improve the lighting to assure adequate visibility

Confirm a Visual Factory exists to assure proper communication of status of machines

Implement Kanbans to assure enough inventory for the process step

Reword the standardized work instructions to use active verbs and not passive phrases

For a Kanban to be successful which of these must occur?

Fairly stable process demand of product or service

Low defect rate of incoming product or service

SPC Charts are used extensively in different business and decision-making environments. In this example a vendor is being selected based on speed of delivery. Which of the conclusions would help you pick a vendor for your needs regarding lead-time of delivery from your vendors? (Note: There are 4 correct answers).

Vendor B as it has a better consistency (lower variance) on lead time

Vendor B since Vendor A shows a situation out of control as shown in red

Vendor B since the Control Limits are much narrower than Vendor A

Vendor B has higher lead time, but a process with much narrower Control Limits

Vendor A with a much shorter lead time in delivery

Vendor B as it has a better consistency (lower variance) on lead time

Vendor B since Vendor A shows a situation out of control as shown in red

Vendor B since the Control Limits are much narrower than Vendor A

Vendor B has higher lead time, but a process with much narrower Control Limits

Which of these elements are not included in Implementation plans?

Planned audits of work completion

Which of these are examples of business metrics or Key Performance Indicators commonly referred to as KPI's?

Which statements are correct about the advanced Capability Analysis shown here?

(Note: There are 3 correct answers).

Six Sigma ICBB image Question 121 72347 09232024004307000000

A.

This is a Poisson Capability Analysis.

B.

The average DPU with 95% confidence is between 0.024 and 0.0295.

C.

The DPU does not seem to vary depending on sample size.

D.

The process shows only one instance of being out of control statistically so we have confidence in the estimated DPU of this process.

E.

The maximum DPU in one observation was nearly 0.0753.
