I thought I would post a follow-up to my "gripes" from some months back.
I'll give VIN credit in that I was contacted by one my reps and we did go over several issues and some things have been addressed since then.
From my end the system itself works pretty well and indeed we do like everything this tool can do for us. We've had more personal involvement from my General Manager which has helped smooth over relations with many of our salespeople and managers and made it very clear they need to get over whatever learning curve and hurdles they can't seem to get by.
Some of my gripes remain largely the same in that many portions of the interface (not the UI itself, just the layout of things) are unintuitive and obviously tacked on. It is rife with spelling errors and grammatical errors, which I realize does not expressly impact performance but it does certainly look less professional than it could. I chalk this one up to the fact I have rarely ever met a developer working for any company who could write their way through their own name without a spelling mistake.
The largest issue still stands; performance and reliability. There have obviously been strides to improve this in recent months and my frustrating explanations to managers have been few and far between since the dawn of 2011, so a kudos is due for those improvements I would say.
Like I said originally, we really do like VIN and what it does. It's getting easier to like it and it needs to make fewer apologies; if you're having problems, stick with it and keep riding your support rep(s).
