TT-TE-TTM 533_1 TT-TE-TTM 533 Lean Six Sigma PROCESS CAPABILITY

TT-TE-TTM 533_2 TT-TE-TTM 533 Lean Six Sigma Objectives Discuss process capability terms Illustrate assessing process capability Understand the different capability indices Calculate process capability using JMP 17 Discuss using run charts and Pareto charts to establish a process baseline Review the Measure Tollgate

TT-TE-TTM 533_3 TT-TE-TTM 533 Lean Six Sigma Process Baseline The team’ s last task in Measure is to report the current process baseline. The team will continue to collect data on the project metric throughout the project and compare it to the baseline. Process capability is one way to report the process baseline. Graphically, the baseline may be reported with a run chart or even a Pareto plot.

TT-TE-TTM 533_4 TT-TE-TTM 533 Lean Six Sigma Process Capability Terminology Specification Limits Boundaries, usually set by management, engineering or customers, within which a process must operate Voice of the customer Is the service or product meeting the customer’ s expectations? Process Capability Compares the output of an in-control process to specification limits using capability indices Answers the question of how well a process meets a customer’ s expectations

TT-TE-TTM 533_5 TT-TE-TTM 533 Lean Six Sigma Why Assess Process Capability? Allows us to quantify the nature of the problem we will attack as one of the following: ▪ Are the specifications correct for the parameter (Y) of interest (process or performance output variable)? ▪ Is the location of the central tendency of the parameter (Y) centered within the appropriate specifications? ▪ Is the process variation in the parameter greater than allowed by the specifications? ▪ Is the measurement system affecting our ability to assess true process capability? Allows the organization to predict defect levels.
