Business Problem & Impact
GEAE shop floor end users experience unnecessary downtime during
system replacement, due to incomplete configuration and uninstalled Process Capability – Before
required applications . One shop floor workstation can be down for days T USL

Root Causes: There is no process or documentation detailing the Shop 0.02

MSA Results: An MSA was not performed during Measure for the
following reasons: 1.Cost in labor to complete a measure MSA was to
great to complete. 2. GE ITS did not control the process used in baseline 0
