I have a colleague that often use this expression "Gating process". Example, "Once this is done, we will need to proceed to the Gating process". I would like to know what he mean.
I'm not a teacher...
Here are a couple of internet articles which may help you understand this phrase:
DLR?s Gating Process - Data Center Guidelines and Checklist for Design and Construction
To summarize these articles - a gating process is a decision making tool implementing GO/NO-GO decision points (the gates) at various points along the way.
This seems the most likely meaning given the limited context of the original question.
[Other possibility - unlikely]
There is also an electronic component which is referred to as a gate. The supporting electronic circuits could be referred to as the gating process, but such use would be unusual.
Thank you. That make sense.
