Yes. The Explore plan includes the OEE tracker and the other four starter kits with no credit card. You can run it on the demo plant immediately and connect your own downtime and production exports when you sign up.
Availability × Performance × Quality, using your plant's own definitions: which downtime reason codes count as planned, the ideal cycle time per machine, and first-pass yield for quality. Every number shows the records and definition it came from.
That is what it is for. Drop the spreadsheet you keep today; columns are matched to lines, machines and shifts, and the tracker runs on it from then on — by email, folder or upload.
