First of all, sorry if this is the wrong forum to post in.
I've got what i think is a rather specific question, related to web-development.
about six months ago, i spend a few months developing an internal application for my internship, about 1 week before i left, it was done.
back then i've already given multipl courses in the use of my application, and even improved a bit based on their feedback (mostly cosmetical).
when i left, i was out of feedback and thus assumed my program was ready for use. it works, everyone got instructions and there's a shiney manual availble to all.
now i'm there on a vacation job, but the application has been eating dust and the clients didn't get it (anymore).
i gave courses, got no comments but still they didn't use the application. one of them didn't even know how to use it, despise being instructed and supplies with an manual.
i'm gone in a few weeks, and i'm the only programmer here. so if anything needs to be changed this is the last chance.
these clients here are about technical enough to know how to power the machine on, so my question is: how do you bring a (imo rather complex) application to them?
