Ducati: is it unreasonable to expect that when an update" breaks other parts of the game
From the investors perspective, yeah it is. WGT still has to do what the investors want, first. Then comes a few bug fixes with whatever time is left over. This is where triage comes in "what can we get done this month given the time we have left after the investor stuff is done." Usually that's a matter of a couple of days. Software development deadlines are extremely tight, and the investors like to load you (the project manager) up with stuff that takes 35-40 days to complete, but they want it done in 30. Investors/stakeholders generally don't have a sense of what that actually requires or what needs to happen to get it done. They just want it done.
There was a video I saw once that showed an interaction between a developer, an investor and the project manager. The investor says, "Ok, what I want you to do is draw three parallel lines in blue ink, but one of them should be green." The developer then explains, in futility, why you cannot draw green lines with a blue pen. That's the kinda "we don't really know what's truly going on" response you get from the higher-ups. It's not their job to know small picture stuff. They're looking at big picture.
As such the regression fixes get put off for lack of time.
