What Is a Shift Breakdown in Actuals Tracking? EDGEBIC Definition

A shift breakdown splits one day's hours on a scheduled operation into the shifts that produced them. In EDGEBIC by User Solutions, every scheduled operation carries a per-day record of planned hours, actual hours, and pieces. The shift breakdown is the layer beneath that record: four hours on day shift, three on night shift, instead of a flat seven hours on Monday.

The analogy is a timesheet with a second column. The daily line says Monday, seven hours. The breakdown says Monday morning four, Monday night three. Same total, considerably more useful.

For the broader vocabulary of planning, see the manufacturing glossary.

How a Shift Breakdown Works

An operation on the schedule occupies a work center over some span of time, and that span can cross days. The per-day record is how that span is decomposed into calendar dates: for each date the operation touched, a line carrying the hours planned for that day, the hours actually worked, and any pieces produced.

That is enough on a plant with one shift. A day is a single block, so a day total is unambiguous.

It stops being enough as soon as the plant runs more than one shift. Monday is no longer one block; it is a day shift and a night shift, staffed by different crews, potentially with different capacity, different overtime rules, and different holiday calendars. Seven hours on Monday could be a full day shift with an idle night, a half day and a half night, or almost anything in between.

The shift breakdown resolves that. It decomposes the single day into its constituent shifts, so the record says which shift produced which portion of the day's hours. The daily record remains the roll-up you read at a glance; the breakdown is where the detail lives.

This matters most for three questions. Which crew ran this operation. Whether a shift is consistently over or under its plan. And whether a day total reconciles with what each shift independently reported. None of those can be answered from a day-level number alone.

A Concrete Example

Job 42's milling operation is planned across Monday and Tuesday. The plant runs a day shift from 08:00 to 16:00 and a night shift from 16:00 to midnight.

Monday's daily record reads: planned eight hours, actual seven hours, one hundred fifty pieces. Read on its own, that looks like a slightly short day and nothing more.

Underneath it, the shift breakdown says something more specific. Day shift, four hours. Night shift, three hours.

That changes the reading entirely. The plan expected the operation to run through the day shift, and it only got four hours there, with the remainder picked up at night. Something interrupted the day crew. Maybe a material wait, maybe a machine problem, maybe an operator pulled onto a rush job. Whatever it was, it happened during the day and the night crew absorbed the shortfall.

Now look at the same breakdown across the whole week. If day shift is short on Monday, Tuesday, and Wednesday while night shift consistently runs over, that is not an incident, it is a pattern, and it is a pattern you cannot see at all from the day totals. The breakdown is what makes it visible.

How EDGEBIC Uses It

The shift breakdown is the per-shift layer of the daily actuals record:

• It decomposes a day. Each day's record for an operation can carry the hours attributable to each shift that worked it, so a two-shift day reads as two lines rather than one aggregate.
• It reconciles crew reporting. When a day total does not match what a crew says it ran, the breakdown localizes the discrepancy to a shift instead of leaving it as an unexplained difference on a day.
• It matters in proportion to your shift count. On a single-shift plant it duplicates the day total; on a multi-shift plant it is where the useful detail sits.
