Chart erratum and refactoring

A computer program product comprising:

• one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:
• evaluating, by one or more processors, a specimen chart relative to a chart erratum model comprising features mapped to an optimum state for a first chart type;
• generating a first risk score for a first sample feature of the specimen chart, wherein the first risk score comprises a delta from the optimum state;
• and
• refactoring the specimen chart to mitigate the first risk score of the first sample feature.
