I wasn't able to read this entire thread but did read some of it! Right now my company is in the middle of figuring out what type of software to use for procedures and documentations. We have gone over a good amount of options but are now testing Google Drive/Docs. We had a DokuWiki up and running for a while but it didn't catch on to even the small group of people deciding on what software to use. BTW ISO is the end goal and what started all of this.
Question: I assume each person has a username and password? Otherwise, it would be difficult to ID who made each edit. This also allows permissions. However, does anyone have any employees that work off site? Or field service techs/engineers, contractors, etc that need offline access to the materials?
If so, what options are there and how do you access from offsite? VPN I'm assuming unless the Wiki is not on the company intranet.
Currently reading the link from the OP and I will probably have more questions as I continue. I tried to post the link but I do not have 10 posts yet
