Record keeping when it stops being optional

Two purposes, one record

The diagnostic log exists so you can find out why the August batches were soft. The compliance record exists so somebody else can see the filed process was followed. They overlap heavily and they are not identical: the second has requirements about what is captured and how long it is kept, and those come from your process authority and your state rather than from what you find useful.

Ask what is expected before designing the form. A log built for both from the start is one log; a log built for curiosity and retrofitted later is two, and the retrofit always lands in a busy season.

Traceability is the part people add late

Being able to say which jars came from which batch, and which cucumbers went into it, is what turns a problem into a recall of a lot rather than a recall of everything. That needs a batch code that actually reaches the jar, which is a labeling decision as much as a record-keeping one and is much cheaper to design in than to add.

Keep it where the work is

The constraint is unchanged by scale: a record written during the work is worth more than one reconstructed after it, which means it has to be physically present and simple to complete. The most common failure at volume is a more thorough form that gets filled in less often.

More people means the form has to stand alone

A log kept by one person can rely on things that person knows. A log filled in by whoever is on the line cannot, and this is where vague fields start producing vague records. Say what each field means and what units it is in, on the form itself, because the alternative is discovering in February that half a season of temperatures were recorded by three people who each meant something different by "warm".
