The plant on one page
As a plant manager you don't watch one line — you run the whole floor against a number and a ledger. This module teaches you to read rolled-up OEE/TEEP and the savings ledger as a single operating view, so you spend attention where it changes money.
Roll-up, don't average blindly
OEE rolls up from station to line to plant, but a plant-level OEE number hides where the loss lives. Your job is to read the roll-up top-down and drill on the worst contributor, not to celebrate or panic over the headline. A high plant OEE can still hide one constraint line bleeding the schedule.
Read OEE as its three factors — Availability, Performance, Quality — at every level. The factor that's lowest tells you which of the Six Big Losses to chase. A plant strong on Quality but weak on Availability has a downtime problem, not a scrap problem, and that distinction decides who you call into the room.
- ›Availability low → downtime/changeover losses
- ›Performance low → speed/minor-stop losses
- ›Quality low → defect/startup-reject losses
OEE tells you 'how well,' TEEP tells you 'how much is left'
OEE measures how well you run during scheduled time. TEEP measures the same effectiveness against all calendar time, so it exposes unscheduled hours — the capacity you own but aren't using. On one page, OEE drives improvement work and TEEP drives capacity and capex conversations.
When someone says the plant is 'maxed out,' the TEEP number settles it. If TEEP is well below OEE, you have idle calendar time before you have a true constraint.
The ledger is the second half of the page
Effectiveness numbers say where you're losing; the verified-savings ledger says what you've actually recovered and banked. Reading them together turns a status dashboard into an operating view: losses on the left, finance-verified recoveries on the right. If OEE is improving but the ledger isn't moving, your gains aren't reaching the P&L — and that gap is itself a signal to investigate.
Read top-down: OEE shows how well you run, TEEP shows how much capacity is left, and the verified ledger shows what actually hit the P&L. One page, three lenses.
Plant OEE is up two points week-over-week and looks healthy on the headline tile. But the savings ledger is flat, and Line 3 — your constraint line — shows Availability as its weakest factor while two other lines carry the average up.
What do you do first?
Plant TEEP is far below plant OEE. What does that primarily indicate?
