Standard work adherence
First, check if tasks follow defined procedures.
Quality checks
Then, verify inspection points.
Safety compliance
Next, ensure safety rules are followed.
Equipment condition
After that, check tools and machines.
Material handling
Also, review handling and storage.
Documentation
