I have not had a chance to watch the recent Cosmos television series, but I do remember the one from 1980. It starred Carl Sagan, who commented on the importance of scientists being open-minded. Sagen said, It often happens that scientists say, you know, that's a really good argument. My position is mistaken. And then they actually change their minds. You never hear that old view from them again. They really do it. It doesn't happen as often as it should because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. I don't want to talk about politics and religion, but I'd like to add Agile to Sagan's list. There are too many of us. who are no longer as open-minded about various aspects of Agile or Scrum as we should be. When confronted with a great view that is different from our own, we don't say, you know, that's a really good argument. My position is mistaken. As Sagan says, a good scientist should do. At least we do not say it as often as should. You are investing a lot of time to be here, and you or your company has paid for you to here. It would be a shame if you went back to your job after this is over and haven't changed your mind about anything. To do that would mean you haven' grown or improved. My challenge to each of us, myself especially, is while we are here to find something about which we can say later You know, that's a really good argument. My position is mistaken. Without this willingness to change our minds, we are no longer improving. So let's remain open-minded. Let's question our assumptions. Something you're doing is working for you, but is it working because of something unique to your domain or something you need about your team or about you situation? When someone here tells you about some alternative approach that also works, be open to it. Remind yourself you could be wrong about the general applicability of whatever has been working for you. Let's all remember to be intellectually humble. We don't want to the singers on America's Got Talent who don' have talent. Remember that the less we know about a subject, the least we think there is to know, about that subject. A true expert at Agile realizes he or she can probably never be an expert in Agiles because people are involved and we're hard to predict. And let's not get hung up by our brand loyalties. Sure, we all may have our preferences. I love Scrum. For the most part, it pays my bills. But the two ideas I'm most closely associated with, user stories and story points, Both come from extreme programming. Look around and use the best ideas wherever you find them and in whatever process you found them. Let go of knowing. Be open to experimentation. be willing to say, as Carl Sagan said we should, that's a really good argument. My position is mistaken. If you loosen your grip on your own certainty just a bit, what I think you'll find is a whole world of possibilities, a new path to learning and growth that you might never have considered. But that's just what I think. And hey, I could be wrong.
