had a 200 screen mockup in invision handed to me. it was obvious that a few different teams at the design agency had worked on it: screens 1-25 had a certain nav bar 26-39 had the same nav bar, but everything a few pixels off with a slightly smaller font in off-white, vs white. screens 40-70 alternated between the first to nav bars, and introduced pull down select boxes with multiple checkboxes in them. the multiple checkboxes represented - in some cases mutually exclusive combinations of things which contrasted with other nav options. ... and so on. Things had to look pixel-perfect - "look, it's a design agency, they put a lot of work in to thinking about how this is supposed to look and work". So.. you'd make the screens exactly the same ('just export all the CSS for each page', etc). But then, when using the app in development, if you went between various screens, and saw the discrepancies - font sizes changes in nav, for example - that caused more negative feedback - "this is broken!". I tried to demonstrate the design screens were the problem themselves by just paginating between the invision slides - you could see the font sizes jump/change immediately. "now you're just being negative". I didn't last very long on that project...
