In my years working in software development from a marketing perspective, the right way always seems a bit too subjective from the people who are advocating change. That doesn't mean it's not subjective if you truly sit down and think about it. The problem is how it's delivered and sold.

At the end of the day, I've come to the understanding that even from a non-software development position, I could point out a dozen of those "but we've always done it that way" examples that are hindering the development, the product and so forth.

It doesn't matter what I or others would say, it's simply hard as hell to get change. And based on my experience, it's pretty common and mostly attributed to the fact it's easier going in the (bad) direction you already going rather than stopping, considering a new direction and heading into the direction just as quickly as you were before.
