Agile in a nutshell

A lot has been written about Agile and its faster and crazier sibling DevOps.  I won't repeat it all here, but I'm generally sold.  For those that aren't convinced or are trying to convince others, you may like this great infographic that explains the most important parts.  This time, it's an artist describing their process of creation, but the same lessons hold: failure (that is: a non-ideal outcome) is not shameful.  It is an inherent part of creation, and to think otherwise is just lying to yourself.  Building something of value will always involve a lot of "missteps."  Deming was right - continuous improvement consistently beats dazzling one-time herculean efforts - but continuous improvements don't make the news.  How do you celebrate and market continuous improvement?
