OEE Dashboard

The Dashboard shows OEE for one machine, on one shift, on one date — together with what caused the downtime, and a way to close the shift off once it's over.

Reading the figures

Pick a Machine, a Shift and a Date. Four gauges appear:

  • OEE — the three parts multiplied together
  • Availability, Performance and Quality — see the overview for what each one means

Underneath, the same shift is broken down into the raw numbers the gauges came from: Planned time, Runtime, Downtime, and the Total Count with the good count alongside it.

Until you've chosen a machine and a shift, the page reminds you that OEE is always worked out from logged downtime and production counts, never entered directly.

Note

If a gauge is blank rather than zero, something needed to work it out is missing. The page says which — see When a figure is blank.

Downtime breakdown

Below the gauges, downtime for the chosen date is grouped by reason, longest first, with the number of times each reason occurred. This is what turns a low Availability into something you can act on: it's the difference between "the line lost three hours" and "the line lost three hours, almost all of it waiting for material".

Stoppages that were never given a reason appear as Unclassified. A long unclassified bar usually means operators are starting stoppages but not choosing a reason when they resume — worth correcting, because those hours can't be acted on.

The trend

Below the figures, OEE Trend charts the same machine and shift over time — OEE alongside Availability, Performance and Quality — with a switch for the last 7, 30 or 90 days. This is the question the gauges can't answer: not "how did today go", but "is this getting better or worse".

Use the table button beside the range controls to read the same figures as numbers instead of lines.

Where the figures come from

Past days are read from a summary Enture builds each night, which is why a long range loads quickly. Days the nightly job hasn't reached yet — today, most obviously — are worked out on the spot, and the chart says how many of those it's showing. Both are calculated the same way, so a day's figure doesn't change when the summary catches up with it.

If a day says it isn't summarised yet, that usually means the nightly job hasn't run for that date. It will fill in on the next run; the underlying logs are never lost.

Closing a shift

Close Shift marks the shift as reconciled for that machine and date. It does two things:

  1. Closes any stoppage still running on that machine, ending it at the moment you close the shift. The confirmation tells you how many were closed this way — if that number is regularly above zero, stoppages aren't being ended when the machine restarts.
  2. Records that the shift was closed, and by whom, so there's a clear line between shifts that have been checked and shifts that haven't.

A shift can only be closed once. Closing it does not freeze or store the OEE figures — they continue to be worked out from the logs, so correcting a mistaken entry afterwards still corrects the figures.

Tip

Close the shift at handover. It's the moment someone is looking at the numbers anyway, and it stops a forgotten stoppage running on into the next shift and distorting both.
