Answer #1

The control chart is a graph used to study how a process changes over time. Data are plotted in time order .

When to Use a Control Chart

  • When controlling ongoing processes by finding and correcting problems as they occur.
  • When predicting the expected range of outcomes from a process.
  • When determining whether a process is stable (in statistical control).
  • When analyzing patterns of process variation from special causes (non-routine events) or common causes (built into the process).
  • When determining whether your quality improvement project should aim to prevent specific problems or to make fundamental changes to the process.

A control chart for fraction nonconforming indicates that the current process average is 0.03. The sample size is constant at 200 units. a) Find the three-sigma control limits for the control chart. b) What is the probability that a shift in the process average to 0.08 will be detected on the first subsequent sample? (Hint: use normal approximation) c) What is the probability that this shift will be detected on the second sample taken after the shift?
