As someone who's been in software development for only a couple years by comparison, I don't see huge architectural changes happen too often for any of our products. This is something that I'm currently trying to improve upon within my company, but I've gotten pretty discouraged with all these comments lol. Is there any way to mitigate the obsoletion of these models?
