**2.7. Step 3: Visit the company during non-production hours**

This step is performed to find out what equipment is operating during non-production hours and find out if it must be operating. You might find support processes - lights, air handling units, compressors - being switched on though there is nothing to support, but also production processes in idle or stand-by mode.

Eyes and ears are useful to find equipment running during non-production hours. The meas‐ urement methods used are the same as during production hours, but the focus may be on other processes.
