Any deployment taking >60 minutes was listed as a defect Sigma (ZLT):Root Causes: There is no process or documentation detailing the Shop 0.02Floor Special Application Installation and Configuration 5MSA Results: An MSA was not performed during Measure for thefollowing reasons: 1.Cost in labor to complete a measure MSA was togreat to complete. 2.
