We develop entire SQF systems on a remote basis without ever stepping foot inside a plant and this includes a full review of the interior and exterior - the facility personnel are tasked with providing an extensive video that we normally get in sections by department, thus being about 3-6 hours worth.
We either supply the client with the best GoPro available and send it to them or they already have one - we can't accept anything less from a clarity standpoint.
At the point of change over to remote from on-site there was most certainly a lot of nervousness, was this the right move, would it be accepted, etc as there is a LOT to be said about being on-site, interacting with the staff and eyes on all areas for inspections.
From a consulting standpoint watching video is quite acceptable because we can't help companies if we don't know what the "bad" is along with the good, technically during a consulting review and prior to the actual development process we are auditing, but it is a different type of audit - we find out what's wrong and then go about helping the facility to fix it, do the installs, repairs, etc.
A bit different auditing and our clients get that - so we get ALL the video, every inch of the facility, all narrated as they go.
With all this being said I can see how an Auditor (having been one) can (and does, such as an SQF desk audit) review standard documentation via systems such as dropbox, cubby, etc. but I don't see how an Auditor could inspect a facility with only a video provided, photo's etc - there is a lot more that goes into an audit than just an experienced set of eyes...
Interactions on the spot are priceless, as is just sitting in car (and what seems like) out by the guard gate and watching ingress and egress or seeing if I could breach safeguards and drive around a building or enter thru a different door, etc. is also priceless.
Interviews with employees, having a "that smells funny" moment during a tour of the facility could ever be replaced with video.
I don't see a way to replace a human being (and not with a robot) walking around a facility, smelling the air, having a... let me look over there moment and watching paint chips vibrate off the ceiling and fall into food products rolling down the line or being able to ask one of the people to run a metal detector check for me watching how one is done.
So, as far as the part requiring "eyes, nose, ears and legs to walk around I do not see a way to replace the on-site visit part - but standard policy type documents, recall plans, etc sure, that can be done off-site.
As to CV - it's being super hyped and 'they" are doing a real job of it.
