Forgiveness over Permission
Much of the agile software movement is about loosening controls, shifting more to asking forgiveness rather than permission. Yet loosening controls isn’t the same as anarchy and no control – a misrepresentation that’s commonly thrown at agilists too. It’s about asking how we can use a minimum of controls, so that that we don’t suffocate the good in our desire to protect ourselves from the bad.
