Some people say, “we’re not changing it, because this is the way it’s done.”
And some people say, “the way it’s done isn’t good enough, let’s make it better.”
In a given situation, you might encounter one or the other type of response. In fact, each of us might adopt one posture or the other.
It’s not “who”, it’s “what do they believe.”
It’s worth thinking about the beliefs of the person you’re talking to before you try to suggest making things better. And it will help you understand the feedback someone else is giving you about your work as well.
