which statements describe characteristics of six sigma?
at six sigma, your processes will be 99.9997% defect - free
the main goal is to capture data on all activities that take place within the organization
the six sigma methodology charts process performance against a mean measurement
six sigma measures as 4.3 defects per million opportunities

Explanation:

• Six Sigma aims for extremely high quality. A key characteristic is a very low defect rate.
• The formula for calculating the defect - free rate in Six Sigma is based on statistical quality control. The defect - free rate \(P = 1-\text{DPMO}\times10^{- 6}\). For Six Sigma, \(\text{DPMO}=3.4\), so \(P=(1 - 3.4\times10^{-6})\times100\%\approx99.9997\%\).
• The main goal of Six Sigma is not just data - capture (that could be a part of a broader data - driven approach in an organization but not the core of Six Sigma). Six Sigma is more about reducing process variation and defects.
• Six Sigma charts process performance against control limits (not just a mean measurement). It uses statistical process control techniques like control charts which have upper and lower control limits around the mean.
• As mentioned above, Six Sigma has a DPMO (Defects Per Million Opportunities) of 3.4 (not 4.3).

Answer:

At Six Sigma, your processes will be 99.9997% defect - free.
