2. Why? IEEE EMC Lab Best Practices
All US Automotive EMC labs have to solve the same problems, but don’t often cooperate on solutions.
This results in:
Different solutions
Duplicate cost/resources

IEEE EMC Lab Best Practices
Customer Reminder & Verification
Customers often schedule, but do not show-up when expected.
Lab Supervisor calls customers 1 week before scheduled start time to remind and verify.
Does anybody else see this problem?
How do you discourage/prevent this behavior?
