Well, I was part of governance team who decides the process on smooth operations of SharePoint post its migration to the new system. One of the pain points was to educate the end user on SP 2013.
Switching MOSS to SP 2013 was a drastic change for the user and they were desperately looking for training materials.One of the common approaches is to create KB articles , but again question arises : how often to update , what topics to add/update and how best one can draft the document which may need the expertise of content writers.
Of course, we came up with this approach for L2 support engineers that was effective in the troubleshooting, however there was a separate tooling system that was integrated with SP and known as VisualSP . VisualSP provides loads of materials in the form of videos ,documentations , tips on the ribbon in specific to a SharePoint page.Furthermore, it also offers In-context help content for the end user.
For instance, If a user is on the SiteSettings page, the tool loads all the help topics/videos on ribbon section in relation to the page, i.e : the possible actions/operations that can be performed on the page.
Installation is quite simple that involves installing a package on a WFE server, followed by an option to expose this feature either to all site collections or specific site collections.The feature enabled will furnish loads of contents and I bet users would find this very handy for their daily operations that further can reduce the support tickets for assitance.In addition, the contents can be hidden from few users by managing their permissions at the site collection level.
