Chart Type matches the description, e.g. variables charts for variables; attribute charts for attributes.
Rational Subgroup definitions are valid (e.g. not “Shiftly,” “20,” same as Description, etc.) and consistent with the process for the Quality Characteristic; if more than one Rational Subgroup is obviously needed (e.g. each cavity of a mold), do not accept if only one Rational Subgroup is identified.
Sample Size is consistent with the chart types (e.g. n = 10 for ¯("X" )/R would be inconsistent).
Sample Frequency is not too low (e.g. 1/day would be too low in most cases, but might be valid for some).
