Is there anything in the world which you can safely use without skills?
If you were the only one able to drive a truck in your company, and you wonder whether someone without those skills could safely drive the company trucks - wouldn't you worry that in the beginning there might be some fatal crashes?
In that case, I recommend your company asks for paid services by a third-party - or they take the risk of trial and error. It depends on how mission-critical the eZ publish installation is.
The reason I ask, is that I am trying out EZ publish compared to other. One other alternative I have, is to pay for it by third party.
In your opinion: Is it possible to set up an installation of EZ Publish and make it work? without any flaws, except the occasional reboot once in a while?
The person that would take over after me, would be capable of setting up user permission and that sort of thing, but not anything more advanced than that.
I have had 5-6 clients with no support contract that have worked in their ez 3.2 and 3.4 installations for years without ever contacting me with problems. Their content is still up to date, so I would guess that would suggest it can be used without too much in the way of webmaster-type technical skills.
They will likely be able to maintain the content just fine.
Updating I doubt: That's sometimes challenging even for seasoned admins of ezpublish ;). And I'd say the same for most CMS out there. Changing content should be simple, changing the system itself is often dangerous. If the site is mission critical, they should definitely get a support contract for it.
The main issue I see is this: if eZ had a security issue which was solved by an update, people without enough knowledge to install the update (or even KNOW they had to install it in the first place!) would be left in the cold. And it would potentiatlly give put eZPublish in a bad light if unpatched sites got hacked, too (I know everyone not updating their webapps has themselves to blame, but really, the public perception often isn't that clearcut with regards to this).
