Statistical Process Control for Failure Rates

P and np charts are appropriate for dichotomous data in categorizing which processes are in control and which processes are failing. As a current or future health care administration leader, your commitment to quality will reinforce the use of these charts to execute decision making for the promotion of efficient and effective health care delivery systems.

For this Discussion, review the resources for this week regarding control charts for attribute variables. Then, evaluate how your organization, or one with which you are familiar, might use the control chart to evaluate whether a process is in control.

NOTE: For this Discussion, you will be required to run the SPSS software platform.

Post a description of one of the control charts presented in the resources for this week and explain a process where it might be used. Be specific and provide examples. Then, create the appropriate control chart for the process you described using fictitious data. Attach this chart. Do not use real data. Explain whether the process you chose is under control or not, and explain why.
