It's easy now to look back and say we would have done different. We can learn from things like the Titanic but unfotunately a lot of those people did not have the opportunity to correct their own mistakes 'cause they died.

I have had my Titanic moment when I started developing business systems and the first time it ran at the clients' company. A user came to me and told me of a bug in my system and I said: "Impossible! There cannot be a bug in this sytem!" Well, I fell flat on my face and had to apologize. Fortunately my system wasn't a boat that could sink and people lose their lives.
