What is Downtime?
Downtime
The equipment stops running when it should be running.
What it means
Downtime is time when equipment is down for various reasons, such as breakdowns, waiting for materials, or replacing items. Record when, how much, and why you stopped.
All we know is that the equipment is stopped. The reason must be written down by someone. Only when the reasons accumulate can you decide what to fix first.
At the pen factory
On the 19th day, the assembly machine stood for 30 minutes from 10:20 to 50:00. Record “spring jammed.” Upon inspection the next day, the screws on the spring feeder are found to be loose.
Why it matters
Without records, no one knows how many times the same breakdown occurred this month.
