One of the most common types of mistakes/errors that I've seen in the industry is simply forgetting to fill out a blank on a form or record.
Nothing is worse than doing record review and finding that someone has left something important blank which will be required to release product. One example we have is forgetting to initial that an important ingredient was added in a batching/mixing record (secondary verification).
I've seen reference to mistake-proof records in the past. Obviously there is no perfect solution, but what ideas for formatting and process have others had success with to reduce mistakes and blanks on forms and records?
