DescriptionProcess Capability is the process by which variation is studied. Process capability is generally thought about in terms of long-term variation. That is, the total inherent variation that can be expected from the process over a long period of time. Students will learn about the various types of process capability studies and the circumstances under which to choose one type of study over another. This course will be most useful to people who are accountable for maintaining the integrity of their organization's machinery and the efficiency of its processes. The course length is 4 hours and will include detailed instruction, periodic assessments, and a certificate of completion upon successful review. Lesson 1: Process Capability Studies
- Identify examples of real-world situations in which a process capability study could be useful
- Identify the equations associated with process capability studies
Select the times during the life of a process where a process capability study can be run
- Identify the appropriate equation for long-term studies vs. single time studies
- Select the common pitfalls or limitations associated with conducting a process capability study
- Identify factors that contribute to the limitations of process capability studies
- Analyze a scenario that describes a process capability study
Lesson 2: Types of Process Capability Studies
- Identify the three types of process capability studies
- Match the three types of process capability studies to their respective characteristics
- Associate basic design layouts with their respective process capability study type
- Analyze a scenario about a process capability study and determine its type based on its characteristics and design layout
Lesson 3: Planning Capability Studies
- Identify examples of items that should be considered before the process capability study begins
- Place the five steps for evaluating the capability of a process in order
- Discern between formal and informal statistical techniques used to determine normal process distribution
- Estimate inherent variability by calculating the standard deviation
Lesson 4: Process Capability Indexes
- Match the three performance measures with their respective uses
- Determine whether a process is capable of meeting specified tolerances by using Cp
- Determine whether a process is capable of meeting specified tolerances by using Cpk
- Apply the Cp and Cpk indexes to determine whether a process is capable when presented with a real-life scenario
