C-Charts
A C-Chart shows how a process, measured by the number of nonconformities per item or group of items,
changes over time. Nonconformities are defects or occurrences found in the sampled subgroup. They
can be described as any characteristic that is present but should not be, or any characteristic that is not
present but should be. For example a scratch, dent, bubble, blemish, missing button, and a tear would
all be nonconformities.
