The TEEPTRAK approach

Stop estimating the losses. Measure them on every machine.

The calculators on this site run on your estimates. TEEPTRAK replaces the estimates with measured data: every stop with its duration and reason, every cycle and every scrapped part, machine by machine and shift by shift.

Availability, performance and quality losses recorded automatically, not typed in at the end of the shift
Stop reasons entered by operators at the machine, in their own language
OEE per machine, line and shift, live on the shop floor and in management reports

Used in 700+ factories. At Hutchinson, OEE rose from 47% to 72%. Installed with a module wired into the electrical cabinet and a sensor at the edge of the line. No PLC changes. TEEPTRAK is not an MES: it measures, so you know what to fix first.
