Code Organization & Language
• Tighten up the language– Consistency of style– Reduce verbiage
• Include resource CD– Code in searchable text form– Documentary information– Supplementary information
Keep the Good Stuff“All measurement systems may produce
spurious data points, also known as outliers,
strays, mavericks, rogues, or wild points.”
