In Part Three of your course project, you will continue working with the process you used to complete Part Two (either your own process or the hypothetical call center process). You will determine the capability of that process and propose a strategy to decrease potential sources of variability. To complete this part of the project: 1. Use the Capability Ratio Calculator to determine how capable the process is. 2. Identify what the standard deviation of the process needs to be for it to be six-sigma capable with respect to the control variable(s). 3. Indicate what you believe are the two main sources of variability within the process and propose a strategy to decrease them to the levels required to achieve six-sigma capability. (If your process is already six-sigma capable, describe the strategies your organization uses to maintain low levels of variability.)
