What are the Big Six Losses?

Six Big Losses refer to the top six kinds of losses that every manufacturing organization faces:

1. Equipment Failure

2. Setup and Adjustments

3. Idling and Minor Stops

4. Reduced Speed

5. Process Defects

6. Reduced Yield

If you drill-down the performance, availability and quality losses of OEE, you will arrive at these six major losses, which can be used to improve manufacturing productivity. The Six Big Losses can help an organization mitigate the problems that arise with:

• Performance loss, reducing preventable downtime and any unforeseen stops.

• Availability loss, reducing stops caused due to reduced speeds or idling or minor stops.

• Quality loss, reducing defects caused due to poor process.
