Q

What is meant by a Statistical Process Control (SPC)?

A
  1. Uses statistics and control charts to tell when to take corrective action
  2. Drives process improvement
  3. Four key steps
    ► Measure the process
    ► When a change is indicated, find the
    assignable cause
    ► Eliminate or incorporate the cause
    ► Restart the revised process

Q

What are the three approaches of Quality control approaches?

A

► Statistical Process Control (SPC) - The objective of a process control system is to provide a statistical signal when assignable causes of variation are present
► Process Capability
► Acceptance Sampling

Q

IN terms of x_hat - chart and R-chart, what is difference when between them?

A
  1. The x_hat - chart detects shift in central tendenceny which is something that the R-chart doesn’t. (if the sampling mean alters)
  2. The x_hat - chart doesn’t changes in dispersion which is something that the R-chart does. (if the distribution is wider).

Q

What are 3 managerial issues with control charts?

Study These Flashcards
A
  1. selecting points in the process that needs SPC
  2. Determine the appropiate charting technique
  3. Set clear and specific SPC policies and procedures
17
Q

What is meant by Process Capability?

Study These Flashcards
A

Process capability is a measure of the relationship between the natural variation of the process and the design specifications

18
Q

What is meant by Process Capability ratio?

Study These Flashcards
A

Cp= [ Upper specification - Lower specification] / (6 * sigma)

► A capable process must have a Cp of at least 1.0
► Does not look at how well the process is centered in the specification range
► Often a target value of Cp = 1.33 is used to allow for off-center processes
► Six Sigma quality requires a Cp = 2.0

19
Q

What is meant by Acceptance Sampling?

Study These Flashcards
A
  1. Form of quality testing used for incoming materials or finished goods
    ► Take samples at random from a lot (shipment) of items
    ► Inspect each of the items in the sample
    ► Decide whether to reject the whole lot
    based on the inspection results
  2. Only screens lots; does not drive quality improvement efforts
20
Q

What is meant by an Operating Characteristic Curve?

Study These Flashcards
A

► Shows how well a sampling plan discriminates between good and bad lots (shipments)
► Shows the relationship between the probability of accepting a lot and its quality level
