What is after-field grade in CS?

The term "post-field" (after-field grade) in the context of CS (Computer Science) is not standard and likely represents an error or specific jargon. It may refer to "post-field grading" or an assessment after data processing in a field. In product management, this could mean evaluating quality or results after data collection at a certain stage (field — data area). For an accurate answer, the context or terminology needs to be clarified.
