What Is a Production Log

A production log is a written record of what a plant made, when it was made, and the conditions it was made under. It’s the document a manufacturer uses to prove exactly what came off the line on any given day.

It’s easy to mix up a production log with a shift log or a shift report, but each one does a different job. A shift log records general events during the shift. A shift report summarises how the shift performed. A production log is narrower than both. It only focuses on the product itself.

A typical production log includes:

• The date, shift, line, and operator
• The product code and batch or lot number
• Start time, stop time, and total run time
• How much was planned and how much was actually produced
• The raw material lot numbers used
• Quality checks done during the run
• Any deviation, hold, or rework that came up

In regulated industries, a production log isn’t just paperwork. It’s the record someone follows backwards if there’s a recall, a customer complaint, or an audit. Without a clear log, a batch becomes hard to trace, even if the product itself is fine.

There are two common problems with production logs. The first is transcription. Operators write numbers on paper at the line, then re-type them into a system later, and small errors creep in along the way. The second is delay. By the time the data reaches anyone who could act on it, the shift is already over.

A digital production log fixes both. The data is captured once, at the line, and shared in real time with supervisors, quality, and planning, so nothing gets re-typed and nothing gets missed.

EviView’s forms and workflows help teams capture production data once, at the source, with full traceability across every shift and line. See how it works.
