Understand estimated due dates
Plan maintenance using operating hours and reading history.

- Check that the job has usable reading history.
- Treat the estimated date as a forecast based on recorded running hours.
- Update readings when equipment usage changes rather than relying on an old estimate.
Example
A machine that runs more frequently can reach its target sooner. New readings provide the information needed to revise the forecast.
Check the result: Update readings when equipment usage changes rather than relying on an old estimate.
